In: National Seminar on Emerging Issues in Biodiversity Management, 8-9 January 2009. IUCN Commission on Ecosystem Management (CEM), Bharatidasan University, Tiruchirappalli, Tamil Nadu, India. Abstract: This article highlights the inter-relationship among existing biodiversity and socio-economic concerns of native people inhabiting the Garo Hills in Meghalaya, Northeast India. The socio-economic condition of the indigenous people of the Garo Hills has changed rapidly of the past century. Since, the majority of land belongs to individuals or local community, therefore, the conservation scenario in this part of country is quite different compared to the rest of India. Mass scale practice of traditional shifting cultivation (or jhum), with increasingly short fallow periods, is one the major causes of the degradation of native old forests. The analysis of Zone of Influence (or buffer around existing protected area network (PAN) revealed that proportion of agricultural, jhum and scrubland in close proximity of PAN is very low that indicates low anthropogenic pressures on native forests. Also, we recorded 108 tree species that local people use for various purposes. State government has established an eco-development Society to take care of 134 villages around Balpakram and Nokrek National Parks. As regards the forest management practices inside the community owned areas, the main emphasis has been on the strict protection of the ‘village community reserves’ in the midst of jhum areas. Such examples exist near Nokrek, Balpakram, Baghmara and Emangiri area and could provide the basis for further forest biodiversity conservation.

    Abstract: As part of a larger Polar Bear Science Team effort with USDI Geological Survey, analyses were made of historic, current, and future (next century) habitat and populations of polar bears in four ecoregions throughout their global distribution. Habitat carrying capacity was modeled using a simple analytic framework, projecting future capacity as a function of present polar bear crude and ecological densities. Population outcomes were modeled based on potential effects of environmental conditions, prey and foraging habitat availability, and anthropogenic stressors, in a Bayesian network. All future projections were made using minimum, maximum, and ensemble mean values of sea ice conditions summarized from a suite of 10 general circulation models. Polar bear populations were projected to decline during the 21st century throughout their range, and severity of decline depended on future ice floe availability. In 2 ecoregions, most likely outcomes were extirpation within 45-75 years, resulting in overall potential loss of about two-thirds of the world’s current polar bear population by mid-century. The main factor accounting for declines is loss of ice sea habitat.

Todd, M., F. L. Waterhouse, S. Saunders, J. M. Meggs, B. S. Lindgren, and B. Marcot. 2008. Monitoring ground arthropod functional communities to evaluate the effectiveness of structural retention for biodiversity conservation in coastal forests of British Columbia. Poster presented at International Union of Forest Research Organizations (IUFRO) Conference on Biodiversity in Forest Ecosystems and Landscapes, 5-8 August 2008, Kamloops, Canada. 
    Abstract: We are examining the utility of ground arthropod communities as suitable, sensitive response indicators of structural integrity in coastal forests. To monitor and evaluate the effects of stand-level retention practices on biodiversity and the potential interactions of such management with the effects of climate change, we are exploring cost-effective, logistically straightforward ways of assessing functionally representative biotic responses reflective of ecosystem resilience. The ecosystem approach under investigation examines the responses of ground arthropod functional groups (e.g. trophic or ecosystem process roles) to changing patterns in ecosystem structure and function resulting from different types and degrees of stand-level disturbance. Functional rather than taxonomic diversity becomes the surrogate for biodiversity, with shifts in functional diversity and richness reflecting shifts in microhabitat and microclimate either in direct response to changing conditions, or through interaction with more dominant functional groups under those changed conditions.
    Work began in 2007 in the Roberts Creek Study Forest (RCSF) in the Douglas-fir dominated, dry Coastal Western Hemlock biogeoclimatic sub-zone (CWHdm). The RCSF offers a range of structural types and conditions created through alternative harvest systems applied between 1993 and 1999. Using pitfall traps as the primary sampling tool, our goal is to determine if we can relate the responses (biomass, abundance, diversity) of functional arthropod assemblages to a suite of structural habitat attributes. Arthropod samples are sorted and identified to the level of morphospecies, grouped by functional roles, and response variables analysed relative to key structural variables.
    We present preliminary results on comparative morphospecies assemblages from 2007 samples across various structural types. Approaches to functional group identification are discussed, with linkages to morphological and taxanomic characteristics supporting these groupings. Identification of a sub-set of better known taxa (e.g. Carabidae) will support a comparison of morphospecies with fuller taxonomies, to evaluate the reliability of using morphospecies as a basis for functional community analysis. Multivariate analyses will be used to explore relationships between structural conditions and arthropod community responses. Patterns of functional redundancy, richness and diversity will be examined, as these relate to the functional resilience of the community.

In: 1st Asia Section Regional Meeting of the Society for Conservation Biology, November 17-20, 2005. Kathmandu, Nepal. 
    Abstract: The project demonstrated an approach for integrating protected areas (PA), managed forests, and the intervening matrix to conserve biodiversity and to provide economic and social benefits to urban and rural sectors. The Wildlife Institute of India, US Forest Service, Indira Gandhi National Forest Academy, and several state Forest Departments began this work in 1995. We identified four pilot Conservation Areas (CA) that represent major Indian ecosystems: Terai (north India), Garo Hills (northeast), Satpura Range (central), and Anaimalai Hills (south). In each CA we did a biodiversity assessment, compiled wildlife-habitat relationships information, evaluated forest practices and human use, developed management strategies, and worked with field staff to identify needed changes. A 6-volume management guide (www.wii.gov.in/download/index.html) presents the underpinnings of the approach, wildlife-habitat relationships, and results of the four CA case studies. Primary lessons learned were to think broadly across landscapes; coordinate inventory data and analyses; integrate management across ownerships and allocations; consider cumulative effects; refocus silvicultural and other management practices toward biodiversity issues, as well as meeting human needs; and work with local managers and indigenous users of the forest. The transition to “biodiversity-based forestry” will require continuing education for professionals and experimentation using adaptive management. Our current work focuses on working with field-level planners and managers to implement this strategy.

    Abstract: Evaluating anthropogenic influences on biodiversity should span freshwater aquatic, marine, and terrestrial environments (experience from northwest USA).  Protected areas alone cannot save biodiversity because boundary effects pervade landscapes (Zimbabwe).  Instead, we should clearly articulate goals and realistic expectations for biodiversity elements on each land use allocation (India).  Relying only on individual species (threatened, endemic, indicator, flagship, umbrella species, etc.) will not suffice; we must look across taxonomic and functional groups and also better account for local extirpations of species, subspecies, demes, and metapopulations.  We need a clear classification and valuation method of ecosystem services (Kyoto Accord).  Simplification (Germany, China) and conversion and loss (Ecuador) of forests has degraded biodiversity, but variable retention (Canada) and selection harvesting (Russia) can help maintain forest biodiversity elements.  Integrating cultural and religions interests with sustenance and conservation will be a major theme (Alaska, Malawi, northeast India).  We need to emphasize biodiversity conservation more at local project scales (Cameroon, Congo) and use landscape ecology to redesign urban sprawl and reduce impacts on hydrologic systems (Florida).  Ultimately, population density and growth will determine what our planet will be capable of producing and supporting for centuries to come (China, India, Mexico).

    Abstract: Human activity continues to simplify ecological systems at an accelerating rate. We should argue no further about definitions of biodiversity and instead use broad definitions that include multiple levels of biological organization at multiple scales of space and time. Evaluating anthropogenic influences should span boundaries of freshwater aquatic, marine, and terrestrial environments; we can no longer view such systems independently. We need to view landscapes as quilts of ownerships and mosaics of management emphases. We cannot just rely on protected areas as inviolate islands of pristine ecosystems to save biodiversity because boundary effects pervade landscapes. Instead, we must view the landscape as a whole and clearly articulate goals and realistic expectations for what biodiversity elements can be provided on each ownership or land use allocation. We cannot rely on just indicator species (including flagships, umbrella species, etc.) but instead must look broadly across taxonomic and functional groups. We cannot rely on just focusing on threatened, endangered, rare, and imperiled species (e.g., species global ranking criteria and red data species listings); ensuring that species do not become viability concerns in the first place is the better and far less costly preventative strategy. We need to better study patterns and causes of local extirpations of species, subspecies, morphs, demes, and metapopulations. We cannot focus on just habitats and species; we must also evaluate patterns of key ecological functions of organisms and biophysical ecological process of ecosystems. Asking “what is natural” has little meaning in much of the world and diverts us from the more difficult question of “what elements and processes do we want to influence and provide?” We need a clearer classification of ecosystem services and a way to valuate each category and to evaluate effects of human activities on each category. As much focus is needed on restoring biodiversity as on delineating and protecting existing “hot spots.” Much more emphasis is needed on “bottom up” approaches to providing for local economic, agricultural, and industrial needs in an ecological setting. Conservation and restoration of diverse, self-sustaining ecosystems must be viewed as politically and socially desirable for long-term health of human communities, economies, and cultures. These goals must not be viewed as antithetical and in conflict; they are different sides of the same coin. We need to better incorporate an understanding and emphasis on biodiversity at local scales, to help redesign urban sprawl, work-place and transportation and communication infrastructures, and agricultural and agroforestry systems, all to incorporate and restore key elements of biodiversity (ecosystem elements) for our own long-term health. We should re-energize landscape architecture as an ecological discipline to incorporate elements of biodiversity. Ultimately, though, it is human population density and growth that is the arbiter of the future of biodiversity on this planet; how we design our environments and guide population growth now will determine what our planet will be capable of producing and supporting for centuries to come.

Presented 25 January 2005 at conference on Using Past Ecological Conditions in Resource Planning: Status of the Science and Application Experience. Central Cascades Adaptive Management Partnership and the Northwest Oregon Ecology Group (invited). 
    Abstract: * "range of variation" can be gauged in many ways; I demonstrate and critique use of running means, SD, SE, min-max values, confidence intervals, and frequency histograms, and mention ways to characterize patterns of disturbance events * I suggest using frequency histograms as the best way to show distribution of conditions (over time or space) and their relative amounts, frequencies, or likelihoods; could be useful in a decision modeling and support context, as it shows conditions as probabilities * I demonstrate these statistical analyses with 3 data sets (precipitation, forest cover from Spies' CLAMS model, and actual steelhead counts) having different properties of regularity, periodicity (autocorrelation), and variability * the literature varies all over the board in terms of how range of variation is measured, what parameters are used, what is taken as baseline or reference conditions, and how retrospective studies are used to gauge past conditions and variations * the degree of variation itself is a function of temporal extent and geographic extent of whatever parameter is being analyzed; the longer the time period or wider the area, the more likely to include infrequent, more extreme events, which affect how "variability" is characterized * so the manager really needs to explicitly state the time and space dimensions by which they are gauging range of variation, and have reasons for this; don't just set the dimensions to match some predetermined desired outcome * one should understand the mechanisms behind variability, such as with disturbance dynamics * the manager might consider specifying both desired future conditions AND "desired future dynamics" * also, "historic" or "natural" can be gauged by using retrospective data, by setting some normative goals (thru policy, modeling, etc.), or by using reference landscapes; I critique use of each of these, including your good point that "history is dead"

Poster presentation at conference on Biodiversity Conservation in Plantation Forests, 25-29 April 2005. In: Bordeaux, France. 
    Abstract: Challenges to biodiversity conservation in managed forests of the US Pacific Northwest are a complex mix of biological, socio-economic, policy and management concerns. Biodiversity in regional managed forests are a particular concern, with 20 million hectares (28%) of the landscape in the States of Oregon and Washington having forest cover. Current disturbances across this expanse are predominantly related to timber harvest, but also include recreation, cattle grazing, mining, fire, invasive species, disease and the concern of habitat alteration due to climate change. Over 300 vertebrate species are associated with the humid, western portion of this forested landscape alone, and biodiversity concerns regionally extend to a broader array of taxa including vascular plants, lichens, bryophytes, fungi, vertebrates, and invertebrates. Federal sensitive species lists for agencies managing national forest lands in this western portion (?) include over 100 vertebrate species and about 400 plants, 30 lichens, 10 bryophytes, 35 fungi and 20 mollusks. Forest ecosystem management paradigms across our region now include sustainability concepts for the maintenance of multiple forest resources, including well-distributed populations of native biota and ecosystem functions. However, the priority of biodiversity protection in the mix of commodities conferred from the landscape currently varies with land ownership. A more cohesive, comprehensive plan for biodiversity protection is only beginning to emerge. We synthesize current directions regarding ten topics: 1) biodiversity definitions and objectives; 2) aiming for ecological function; 3) spatial scales of biodiversity assessment; 4) comparing active and passive management approaches; 5) habitat modeling; 6) invasive species; 7) monitoring; 8) information systems; 9) socio-political aspects; and 10) collaborations. Successful conservation programs must clearly identify the definitions, processes or roles of each of these areas in an adaptive management framework in which management is conducted as learning trials from which to evaluate and readjust decisions. Whereas coordinated programmatic oversight is essential, the efforts of individuals and interagency partnerships can be significant and are critical to provide momentum and longevity to the tasks.

    Abstract: We studied elements of a protected area network (PAN) in South Garo Hills and adjacent Nokrek National Park of western Meghalaya, northeast India. Our study area has been named Garo Hills Conservation Area (GCA). The PAN in GCA currently consists of (1) four protected areas (PAs; national parks or wildlife sanctuaries) and (2) five reserved forests (RFs). To more effectively provide jointly for wildlife and people over the long-term, the PAN in GCA could also incorporate formal designation of (3) seven wildlife habitat corridors linking the PAs and RFs, and their buffer zones of influence, and (4) a number of sacred groves in community lands that provide old forest environments. The PAN could also include guidelines to restore and maintain (5) designated zones of old-forest elements among shifting-cultivation or jhum community lands, such as river gallery forests and large-tree patches, and (6) specific substrates and vegetation elements within and between croplands, managed forests, and other high-use areas.
    The mapping and analysis of the landscape in GIS domain revealed that old primary forests covered nearly one-fifth of the landscape. The important forest types, as per Champion and Seth's classification, include the Tropical Moist Evergreen Forest and Tropical Moist Semi Evergreen Forest and Tropical Moist Deciduous Forests. Increasing shifting cultivation coupled with the shortened jhum cycle have been identified as severe threats to native forest and wildlife resources. There is an urgent need to bring the changes for maintaining ecological sustainability to GCA. For this purpose, the recommended actions could be implemented as local demonstrations in GCA to illustrate specific measures and approaches for conserving native old forest or important wildlife habitats. The potential themes identified for demonstration are: 1) Additions to protected areas, 2) Protection of primary forests and mature forests in wildlife corridor habitat areas, and 3) Provision of elements of older secondary forests as wildlife habitat and for biodiversity conservation in heavily jhummed area.

    Abstract: A "Survey and Manage Species Program" has been established under the Northwest Forest Plan (USFS, BLM) that, in part, entails site surveys and annual reviews of rare and little-known species of fungi, lichens, bryophytes, vascular plants, mollusks, and vertebrates in late-successional and old-growth forest reserves. Under this program, colleagues and I have developed 12 species-habitat models using Bayesian belief networks (BBN) in a rigorous procedure involving expert knowledge, peer review and model revision, testing with known site data, and validation and updating with new, random-site data. These species-habitat risk analysis models are intended to help managers predict likelihoods of species presence based on microsite characteristics, and to prioritize sites for expensive and intensive pre-disturbance survey. Thus, their sensitivity to site conditions, and their accuracy of predicting species presence (more so than absence), are paramount and being tested. A second set of BBN models represents risk management in the decision framework for annual species reviews conducted by managers and specialists under the program. These decision models were crafted strictly from the guidelines in the Record of Decision and are helping to ensure consistency in the species reviews, as well as helping to identify hidden inconsistencies in the guidelines. Overall, the species risk analysis models and the decision risk management models are best used to guide thinking and evaluation, not to substitute for human decision-making.

    Abstract: The conservation biology literature offers numerous approaches to assessing and managing individual and multiple species. Main categories of 32 approaches considered here include those aimed at the needs of individual species or groups of species (approaches based on viability of target species, surrogate species, and viability of multiple species) and those aimed at providing for ecological communities and ecosystems (approaches based on geography, range of natural variation, abiotic ecosystem processes, diversity of habitat conditions, and indicators of system status). There is much overlap in the objectives and definitions among many categories of approaches. Although the approaches are not mutually exclusive, they also are not fully interchangeable. The degree to which rare and little-known (RLK) species would be provided varies considerably under each approach. No one approach aside from those explicitly addressing individual RLK species seems to provide a consistently high assurance and likelihood of conserving those species. The least effective single approaches to RLK conservation likely include very broad-based "coarse filter" species or system approaches that provide indeterminate descriptions and guidelines of environmental and ecological factors. The most effective tactic for conservation of RLK species -- short of conducting costly autecological studies -- may be a combination of approaches across scales of biological and system organization that together provide a reasonable level of assurance for species, habitats, and processes that contribute to their viability. The best specific combination of approaches may vary according to existing knowledge, available data on species locations and habitats, characteristics of the ecosystem, other concurrent management schemes and land allocation designs, and especially levels of risk that managers are willing to take.

Poster presented at: Conference on Innovations in Species Conservation: Integrative Approaches to Address Rarity and Risk, April 28-30, 2003. USDA Forest Service and others. Portland, OR. 
    Abstract: We are studying the distribution of terrestrial invertebrates, including rare and little-known species, in old-forest (late successional and old-growth) stand remnants and adjacent forest plantations in the Washington Cascades ... to test hypotheses of the roles of forest remnants in a managed forest landscape. We are analyzing percent occurrence, relative frequency, and relative biomass of terrestrial arthropods from soil/litter sampling, pitfall traps, and beat-and-sweep sampling of low vegetation. Analyses determine how functional groups of species vary across forest remnant size, forest and plantation age, and proximity to forest edge. We classify each species into: old-forest obligate, old-forest source (found mainly in old-forest remnants but disperses into clearcuts), clearcut obligate, clearcut source, edge obligate, or forest-clearcut facultative user. Results will help determine how old-forest remnants and clearcuts serve as key habitat refugia and as sources of inocula of dispersers for all species. Analysis of species by functional group can help pose hypotheses on the organisms' roles in community processes, and how rare and little-known species may be addressed in groups. Results will help validate the Northwest Forest Plan management guidelines on leaving 15% old-forest cover during timber operations, and on the future management of resulting old-forest remnants.

    Abstract: We summarize the research findings of a major research project undertaken in the Garo Hills Conservation Area (GCA), Western Meghalaya and recommend management actions, including recent analysis of elephant habitat and recommendations for applying result in demonstration projects. A landuse and landcover map for GCA landscape (ca. 2,548 sq km) was prepared using remotely sensed data from Satellite IRS-1D of Feb, 1999. The landscape was characterized for 'forest fragmentation' and available 'core areas' using Bio_CAP. About 20 per cent of the landscape is highly fragmented and most of this is situated in southwestern portion of the GCA. The intact and least fragmented area occupied nearly 70 per cent of the landscape. A total numbers of 2,236 and 644 forest patches with the total available core area of 561 sq km and 291 sq km were found at the specified edge distances or buffer width of 250 m and 500 m, respectively. Seven potential wildlife forest habitat corridors were delineated by mapping the least fragmented forest patches those link the protected areas with the smaller fragments of managed forests. The analysis revealed that nearly one-fifth of the landscape was covered by old primary forests, which was mainly composed of the Tropical Moist Evergreen Forest (TMEF) patches. The paper also discusses the vegetation patterns in four different forest types viz. Moist Evergreen, Semi-evergreen, Moist Deciduous and Sal Formation and the effect of shifting cultivation under three successional stages viz. young (up to 15 years), mature (15 to 30 years) and old (more than 30 years) forests. A total of 1062 angiosperms belonging to 578 genera and 154 families were identified during several field visits between year 1997 to 2000. This included 411 tree species belonging to 224 genera and 71 families. The Importance Value Indices of 165 tree species sampled in 35 one-hectare plots were computed. Also the study developed a few elephant-habitat relationship models using population estimates of the State Forest Department for the years 1993 and 1998. Increasing shifting cultivation coupled with the shortened jhum cycle has been identified as one of the most severe threats to the forest resources and the elephant population, which apparently has undergone a 44% decline over the 5-year interval between the two censuses. There is an urgent need to bring the changes for maintaining ecological sustainability in GCA. The recommended actions could be implemented as local demonstrations in GCA to illustrate specific measures and approaches for conserving old forest or important wildlife habitats in GCA. The potential themes identified for demonstration are: 1) Additions to protected areas, 2) Protection of primary forests and mature forests in wildlife corridor habitat areas, and 3) Provision of elements of older secondary forests as wildlife habitat and for biodiversity conservation in heavily jhummed area.

In: Conference on Watersheds Across Boundaries: Science, Sustainability, Security, 3-6 November 2002. Skamania Lodge, Stevenson, WA. 
    Abstract: We present an evaluation of the ecological roles ("key ecological functions" or KEFs) of fish and wildlife as one facet of subbasin assessment in the Columbia River Basin (CRB) of USA and Canada. Using a wildlife-habitat relationships database (IBIS) and GIS, we have mapped KEFs as levels of functional redundancy (numbers of species with particular KEF categories) that may occur within subbasins and subwatersheds historically and at present. Such "functional analyses" complement analyses of habitats and species, and serve to inform on the degree to which wildlife communities are "fully functional" and how that functionality can be influenced by changes in habitats. Our analysis is the first of its kind, particularly in the transboundary CRB. The analysis depicts historic, current, and changes in functional redundancy for selected KEF categories; total functional richness (number of KEF categories performed by all wildlife species in an area); and functional diversity (functional richness weighted by functional redundancy). The maps denote parts of the subbasin that are strong or deficient in specific ecological functions. Land managers could use the maps to guide restoration or conservation priorities for ecological functions of fish and wildlife.

    Abstract: We present maps of "functional analyses" of wildlife throughout the Columbia River Basin of British Columbia and the United States. Functional analyses display geographic patterns of key ecological functions (KEFs, major ecological roles) of wildlife associated with existing terrestrial habitats. They are a way to explicitly depict the degree to which wildlife communities are "fully functional" and how that functionality can be influenced by changes in habitats. To produce the maps, we used published and recently updated databases on wildlife-habitat relations that depict associations of each wildlife species with macrohabitats, and categories of KEFs pertaining to each species, and GIS data on hydrologic unit boundaries and occurrence in each unit of each wildlife species. The maps depict (1) levels of functional redundancy (number of species performing each KEF) for selected KEF categories, (2) total functional richness (number of KEF categories performed by all wildlife species in an area), and (3) functional diversity (functional richness weighted by functional redundancy). The maps help highlight areas strong, or deficient, in specific functions. We also display maps showing changes in the functional analysis parameters since historic time for the U.S. portion, and suggest ways that land managers could use the maps to guide restoration or conservation priorities.

    Abstract: Through the efforts of the Wildlife-Habitat Relationships in Oregon and Washington project and the Northwest Power Planning Council's sub-basin planning process, an opportunity existed to acquire information on the functions that are performed by fish and wildlife. Our presentation will depict the different kinds of functions that fish and wildlife perform and which functions are overlapping. Specifically, we will build a functional web depicting such species' potential interactions or roles using terrestrial <==> riparian <==> aquatic linkages. Findings from a hypothetical stream reach will be shown and an illustration of how this information can be determined across a subbasin will be depicted.

    Abstract: This presentation will give conference attendees an overview of the products of international teamwork that has brought together information on 600 species of terrestrial wildlife, fish, and habitats throughout the entire Columbia Basin of both the US and Canada. Collecting and compiling wildlife-habitat information for this project resulted in an assemblage of 7 data matrices: 1) Wildlife-Habitat Types, 2) Structural Conditions, 3) Habitat Elements, 4) Key Ecological Functions, 5) Life History Characteristics, 6) Salmon, and 7) Management Activities. Information in the 7 matrices has undergone Quality Control, and it also incorporates (where appropriate) confidence levels or literature citations to give the user a sense of the reliability of the data. In total, this effort has received support from nearly 40 organization and has taken over 5 years to complete. Our goal is to develop an international wildlife information system that would disseminate high quality information for education and conservation of the Basin's ecosystems. We are now applying the information to sub-basin planning in the Flathead and Kootenay Rivers on both sides of the US-Canada border.

Multi-species framework: coordinating theory, models and lexicon across spatial scales and between fish and wildlife in the Columbia Basin. In: Joint Meeting, Society for Ecological Restoration and Ecological Society of America, 4-9 August 2002. Tucson AZ. 
    Abstract: The Multi-species Framework is a hierarchical approach to fish and wildlife recovery in the Columbia Basin. Framework biologists developed a theory and lexicon to evaluate populations and ecosystem function in historic, current and the future times. Three alternatives: dam removal, system-wide habitat enhancement and main-stem river enhancement were evaluated for the basin and eleven provinces. Attributes to assess the influence of alternatives in the basin and provinces are a mix of empirical data, modeled data and expert opinion. The next step in the Framework is to collect data to evaluate fish, wildlife and ecosystem function within subbasins of each province. These data will be used to validate the broader-scale basin analyses. Various federal, state and tribal agencies have and continue to align with the Framework to address their various mandates. Models to assess the influence of alternatives share a common population biology theory that link fish and wildlife population analyses and provide a translation of habitat variables to population productivity (lambda), capacity, and abundance. Fish population results quantify historic losses and indicate that the dam removal alternative is likely to produce more fish than habitat improvement alternatives. Wildlife population analyses indicate that alternatives to enhance fish populations could have unanticipated site-specific negative influences on threatened species. Ecosystem function analyses indicate areas in the basin where functional diversity and functional redundancy have been lost or reduced and where alternative management plans might enhance functions.

Marcot, B. G. 2001. Decision support models for plant and animal conservation. In: Restoration and recovery: beyond good intentions. Society for Ecological Restoration Northwest Chapter Conference, 2-6 April 2001. Bellevue WA.
    Abstract: A major challenge in conservation is managing species and ecosystems with scant scientific knowledge and great uncertainty. Decision support models (DSMs) can aid this by (1) evaluating the implications of uncertainty in meeting management goals, (2) combining empirical data with expert judgment, and (3) through sensitivity testing and validation steps, identifying key habitat elements as a basis for prioritizing inventory and monitoring. DSMs include a wide range of tools and include Bayesian analyses and belief network modeling, data and text mining, decision modeling such as decision tree analysis, expert systems, fuzzy logic and fuzzy set theory models, genetic algorithms, rule and network induction, neural networks, reliability analyses, quantitative (environmental) risk analysis, simulation and scenario modeling, and other approaches. Successful use of DSMs for plant and animal conservation depends largely on the availability of data or experts, and the willingness of decision-makers to articulate their risk attitudes and decision criteria. These are no small hurdles. Many DSMs can aid in merging scientific data with expert knowledge, although no model can replace empirical field studies. Several examples of DSMs are demonstrated to illustrate the 3 objectives listed above.

National Symposium on Elephant Conservation, Management and Research, 16-20 December 2001. Rajaji National Park, India. 
    Abstract: Elephant census data were compared with detailed map information on conditions of forest vegetation in the South Garo Hills and Nokrek area of western Meghalaya. Recent increases in slash-and-burn ("jhum") cultivation in the area have decreased forest cover and increased fragmentation of native evergreen, semi-evergreen, and deciduous forests. The analysis determines which vegetation types and fragmentation patterns account for elephant population densities and changes. A system of 7 forest habitat corridors for elephants has been proposed to link protected areas (PAs). We analyze the vegetation conditions for the corridors to help determine the best arrangement of that would provide forest cover for elephants among the PAs

    Abstract: An impediment to developing an integrated ecological approach to watershed management is that wildlife and fish biologists lack a common intellectual tradition and lexicon. Management objectives and terminology differ between the two disciples, which often inhibits communication and progress. In the Multi-species planning process, Ecosystem Diagnosis and Treatment (EDT) provided a common intellectual framework that has fostered a multi-species approach. In this paper we will discuss a fish and wildlife "Rosetta Stone" that argues for the multi-species application of EDT. The theoretical underpinnings of the EDT method are defined in terms of productivity and capacity equations that are taken from the disaggregated Beverton-Holt model of Moussalli and Hilborn.
    The Beverton-Holt model, usually in its aggregated form, has been widely used in fisheries modeling and management. It describes the density-dependent relationship between numbers of recruits and adult spawners that produce them. In its aggregated form, the Beverton-Holt stock-recruit relationship is identical to the difference form of the logistic equation for lag-free density-dependent population growth. The logistic equation as described in ecology text books are more familiar to wildlife biologists than Beverton -Holt equations. The disaggregated form of the Beverton-Holt is identical to the disaggregated form of the logistic model for density-dependent population growth as described by Leslie. Both the Mousalli and Hilborn equation and the Leslie matrix can be expanded mathematically in the same manner to express the expected number of recruits in terms of adult breeders. These points provide a rationale for free translation between EDT information types (e.g. Level 2 habitat description) for fish and wildlife. It also provides a point of commonality between EDT and other models such as those based on a Leslie matrix.

Marcot, B. G. 2000. Key elements of biodiversity in the Columbia River Basin: patterns of diversity, key ecological functions, and evolutionary context. Presented 14 September 2000 to The Wildlife Society 7th Annual Conference. Invited. In: Nashville, TN. 
    Abstract: Total biodiversity of the Interior Columbia Basin consists of an estimated 43,825 species of macro-organisms (but only 39% of these are known from surveys or studies). These include an estimated 18,946 species of plants and allies, 24,270 invertebrates, 609 vertebrates, and hundreds of thousands of micro-organisms including soil bacteria, protozoa, microfungi, and other species critical to ecosystem health and productivity. Most species are unstudied, especially plants and invertebrates. We evaluated a total of 14,028 species and included 1,339 species and 143 species groups in a species-environment relations (SER) database. The SER database includes depictions of each species' key environmental correlates and key ecological functions (KEFs). KEFs depict species' ecological roles as potentially affecting other species. I developed a classification of KEFs and present an analysis of KEF categories. Maintaining species' evolutionary potential is another element of biodiversity which can be described and measured; examples are shown of mapping: habitats at species' range peripheries; disjunct populations; locally endemic species, subspecies, and ecotypes; species' range peripheries; and environments at the edges of species' range of tolerance.

    Abstract: The Terrestrial Staff of the Science Advisory Group has developed “causal web” models relating key environmental correlates (KECs) of wildlife species, to potential population response under several Final EIS alternatives for the Interior Columbia Basin Ecosystem Management Project. The models involve use of Bayesian belief networks (BBNs), which represent conditional probabilities of population response given environmental conditions at two scales of spatial resolution. The KECs were identified by use of literature and expert panels and formalized into a Species-Environment Relations database. The probabilities and BBN model structures were derived from literature and, where needed, expert judgment. The BBN models provide a consistent, testable framework by which to represent simple habitat relations of a wide array of species. Sensitivity analyses using entropy-reduction metrics identify controlling KECs that may be worthy of further study or monitoring. BBN species modeling represents a major step beyond using expert panels to evaluate population viability; it opens the “black box” of expert opinion by formally modeling the subjacent ecological relations.

Marcot, B. G. 1998. Analyzing key ecological functions of wildlife species. Abstract and presentation at: Landscape management of Pacific Northwest forests: exploring practical tools for managers. 19-20 February 1998. Olympia WA.
    Abstract: Key ecological functions (KEFs) of species are those roles that organisms play that ultimately affect the biodiversity, productivity, and sustainability of their ecosystems. Understanding the functional roles and interactions of species is an important facet of ecosystem management but is usually overlooked by land managers. Databases depicting species' KEFs as hierarchical classes can be used to determine several functional parameters of communities, including functional redundancy, functional diversity, functional variance and similarity, and geofunctional ecology. Functional redundancy is the number of species with the same KEF; total functional diversity is the number of KEF categories times the mean number of species per category; functional variance is the variation in redundancy among KEF categories within a community; functional similarity depicts, in dendrograms, the differences among communities in terms of their KEF categories; and geofunctional ecology maps in GIS the ranges of species sharing a common KEF. Such metrics and maps can be used to determine the communities with the greatest functional variance and lowest redundancy in particular KEFs, that is, those potentially at greatest risk of environmental change; and to delineate specific geographic areas with weakest spatial links of particular KEFs across the landscape, for potential conservation or restoration actions. Examples from the interior Columbia River Basin are provided. Using this approach, the manager can also describe the ecological roles of extirpated and extinct species lost from communities; functions of exotic species; and even key ecological functions of humans. Data for a KEF database come from expert panels and literature, but help to craft testable hypotheses and identify major research needs.

Poster presentation at: Landscape management of Pacific Northwest forests: exploring practical tools for managers. 19-20 February 1998. Olympia WA. 
    Abstract: This poster displays a classification system for key environmental correlates and key ecological functions of plants and animals of the interior Columbia Basin; depictions of correlates and functions in Paradox relational databases, as a species-environment relations (SER) model; and use of the SER database to guide and evaluate ecosystem planning for the Columbia Basin. The SER approach is a significant extension to the traditional wildlife-habitat relationships programs and models. Some of the management questions answerable by the SER database include: what species are influenced by manipulating environmental factors? What are the collective ecological functions of a set of species, such as those influenced by management activities? Are there any "threatened ecological functions" deserving special attention, and what environmental conditions are necessary to manage for the species providing these functions? Some lessons learned from the SER approach include: maintaining species' ecological functions can be an explicit part of ecosystem management guidelines; and testable hypotheses regarding the ecological role of wildlife in their ecosystems can be articulated and related to management effects.

Marcot, B. G. 1998. Terrestrial biodiversity and ecological functions. Poster presentation at: Landscape management of Pacific Northwest forests: exploring practical tools for managers. 19-20 February 1998. Olympia WA. 
    Abstract: Results of an assessment of terrestrial biodiversity and ecological functions of species for the interior Columbia Basin Ecosystem Management Project are presented. Total species biodiversity consists of an estimated 43,825 species of macro-organisms (but only 39% of these are known from surveys or studies). These include an estimated 18,946 species of plants and allies, 24,270 invertebrates, and 609 vertebrates (vertebrates constitute only 1% of the total). Most species, especially fungi and invertebrates, are unstudied. Since historic times, wildlife species associated with native grasslands, native shrublands, and old single- and multi-layer forests have declined the most within the study area. Those associated with young successional stages of forests, conifer- encroached sagebrush, and disturbed riparian conditions have increased the most. Findings suggest that key factors to address in ecosystem management are: (1) maintaining all key ecological functions of species as affecting biodiversity, productivity, and sustainability of ecosystems; (2) providing all key environmental correlates--habitats and other factors that influence species viability--for maintaining species at risk; (3) providing for viability and ecological functions of all life forms--fungi, lichens, bryophytes, vascular plants, invertebrates, and vertebrates; (4) maintaining conditions that allow for evolutionary potential of species and ecological integrity of ecosystems; (5) using selected bioindicators for monitoring changes in environmental conditions; (6) maintaining concentration centers and hot spots of biodiversity and species rarity and endemism.

    Abstract: By 1980, it was clear that the rapidly diminishing amounts of old-growth forests in the Pacific Northwest would bring federal land management agencies into conflict with the requirements of the Endangered Species Act. This is a story of the various attempts to come to grips with the inevitable and the interactions of politics and science that came into collision - time after time - until the Federal Courts shut down all timber harvesting activities on federal lands in the Pacific Northwest. This lead to a remarkable series of events that resulted in the "President's Plan" for management of the federal forests of the region which was, and is, the only large-scale application of the principles and techniques of conservation biology. This, in turn, led to the ongoing assessment and planning activities for the Columbia Basin. Lessons learned at each twist and turn in this ongoing story are discussed.
