The Conservation Biology Institute, in collaboration with Ted Weller (USFS – Pacific Southwest Research Station) is expanding the functionality of Data Basin to create a clearinghouse for migratory bat detection data. This new functionality will allow users to: (1) import location-aware spreadsheet data into Data Basin; (2) dynamically visualize these locations and their attributes (such as number of bats of a particular species) within the interactive map; and, (3) explore charts of time series records across one or more locations. Additional tools under development will allow aggregation into a single master dataset, support form-based imports to more easily capture site and detector information from researchers during upload, and support export of records into spatial and non-spatial outputs.
More information about the exciting implications of this project can be found within an article on The Wildlife Society website.
Working as a subcontractor to Dynamac Corporation, the Conservation Biology Institute provided the scientific leadership and technical support for two BLM Rapid Ecoregional Assessment (REAs). The Sonoran Desert ecoregion was completed in the spring of 2012. A series of conservation elements were chosen for the eocregion and over 40 management questions addressed. Most questions pertained to a listed set of change agents, including urban and agriculture development, energy (including renewables), fire, invasive species, recreation, and climate change. For each conservation element, conceptual models were created and, for each specific management question, an accompanying GIS-based process model was created that outlined the data and steps necessary to generate an answer to the question. Part of the project required an exhaustive acquisition and review of available spatial data – hundreds the ecoregion. Extensive and sophisticated modeling had to be applied to multiple topics including target species habitat, natural ecological systems, climate change, invasive species, wildfire, and landscape integrity. Also, some custom analytical software had to be generated throughout the course of the project.
Project review was conducted using Data Basin and final results reside in a private group space on this web-based data management and mapping system. To inquire about access to the data and map-based results, please contact Karen Prentice at BLM Headquarters (kprentice@blm.gov).

CBI investigated the effects of climate and vegetation on the distribution of martens (Martes caurina) and fishers (Martes pennanti) in the Sierra Nevada in California under current and projected 
future conditions to inform conservation efforts for these species and to investigate how different modeling methods and resolutions may affect predictions about species’ responses to climate change. Martens and fishers are closely related forest carnivores of conservation concern in California, where both reach their southernmost distributions. The species have contiguous elevation ranges, with the smaller marten occupying high subalpine forests that experience deep and persistent snow, and the larger fisher occupying mid-elevation forests that experience less snow and warmer temperatures.
The goals of this project were to:
- add robust, downscaled, climate-change effects assessments to CBI’S Sierra Nevada Carnivores project, which is a comprehensive, science-based effort to map areas important to sustaining rare carnivore populations and improving forest management.
- compare alternative analytical approaches and resolutions for assessing climate impacts on vegetation and sensitive species.
Because martens and fishers require similar forest structural conditions (dense forests with large trees and abundant dead wood) but different climate regimes (cooler, moister, and snowier conditions for martens; warmer, drier and less snowy conditions for fishers) they offer a unique opportunity to investigate how our changing climate may affect the species directly as well as via changes in vegetation. Also, because they compete with one another for food, and fishers will kill martens when they meet, this system offers an opportunity to investigate how species interactions may also affect future populations.
Specific study tasks:
- Examine how the current distributions of martens and fishers are influenced by vegetation characteristics (e.g., forest composition and structure), climate (e.g., temperature, precipitation, snow depth and duration), physical variables (e.g., elevation, % slope) and presence or absence of the other species.
- Project the potential future distribution of both species under climate change based on results of Task 1 and using alternative emissions scenarios and general circulation models at different resolutions.
- Use the results to support conservation and forest management plans to ensure long-term sustainability of marten and fisher populations in the face of climate change and increasingly severe fire regimes.

National interest in roadless area conservation dates back to the 1970s when the Forest Service was directed by Congress to inventory roadless areas in response to the public’s growing desire to protect wild landscapes primarily through wilderness designations. In 2001, President Clinton enacted the Roadless Conservation Rule to protect 58.5 million acres of inventoried roadless areas on Forest Service lands, including nearly 2 million acres in Oregon. However, on May 13, 2005 the Bush administration issued a revised rule that established a process for governors to propose locally supported regulations for conserving roadless area within their states. While some states, including Oregon, have legally challenged this rule change, State governments will continue to play a vital role in providing recommendations to the Forest Service concerning the protection of federal roadless areas. This report provides new information on the importance of roadless areas in Oregon that places these areas among the most ecologically valued in the nation, thereby providing a scientific foundation for protecting all of Oregon’s roadless lands regardless of the method to achieve this outcome.
CBI staff outlined the crucial role that Southern Orange County, California, could play in efforts to conserve biodiversity at both global and regional scales and developed a conservation framework for the area. Using principles of conservation planning, they delineated four core biological resource units. That must be conserved essentially intact, without further internal fragmentation by development, to continue supporting key species and ecosystem processes. This information was presented by CBI, in support of the Natural Community Conservation Planning (NCCP) program for the Southern Orange County NCCP subregion, which is the last best hope to conserve a large, ecologically intact representation of the globally unique coastal foothills and terraces ecosystem of southern California.
The Puente-Chino Hills Wildlife Corridor is a peninsula of mostly undeveloped hills jutting about 42 km (26 miles) from the Santa Ana Mountains into the heart of the densely urbanized Los Angeles Basin. Intense public interest in conserving open space here has created a series of reserves and parks along most of the corridor’s length, but significant gaps in protection remain. These natural habitat areas support a surprising diversity of native wildlife, from mountain lions and mule deer to walnut groves, roadrunners, and horned lizards. But maintaining this diversity of life requires maintaining functional connections along the entire length of the corridor, so that wildlife can move between reserves—from one end of the hills to the other.
Already the corridor is fragmented by development and crossed by numerous busy roads, which create hazards and in some cases barriers to wildlife movement. Proposed developments threaten to further degrade or even sever the movement corridor, especially within its so-called “Missing Middle.” This mid-section of the corridor system, stretching from Tonner Canyon on the east to Harbor Boulevard on the west, includes several large properties proposed for new housing, roads, golf courses, and reservoirs. Such developments would reduce habitat area and the capacity to support area-dependent species and, if poorly designed, could block wildlife movement through the corridor.
This report builds on an impressive array of previous ecological and wildlife movement studies in the Puente-Chino Hills, as well as the general literature on wildlife movement corridors as it applies to this unique peninsula of wildness. It supplements the existing information with an analysis of gaps in protection—with special focus on the vulnerable Missing Middle—and recommends conservation and management actions to prevent further loss of ecological connectivity and retain native species.
Wolves were extirpated from the Adirondacks over a century ago due largely to human eradication efforts. The Conservation Biology Institute (Corvallis, OR) was chosen by the Adirondack Citizens Advisory Committee to examine the question of biological feasibility of reintroducing gray wolves back to the Adirondacks. By applying what is known about gray wolf ecology (in general) to the best available spatial and genetics data for the Adirondacks, we examined three basic questions:
- Is there suitable gray wolf habitat in the Adirondacks to support a viable population?
- Is there adequate landscape connectivity both within the Adirondacks and between the Adirondacks and the surrounding region to allow for reasonable gray wolf movement important to their persistence?
- What does the most recent genetics tell us about wolves in the Adirondacks?
The Klamath-Siskiyou ecoregion of southwest Oregon and northwest California has long been recognized for its global biological significance and is considered an Area of Global Botanical Significance by the World Conservation Union, a global Centre of Plant Diversity, and has been proposed as a possible World Heritage Site. More recently, World Wildlife Fund US scored the Klamath-Siskiyou as one of their Global 200 sites reaffirming its global importance from the standpoint of biodiversity.
CBI used GIS as the principle tool to assess the state of the environment in the Klamath-Siskiyou and to develop a reserve design proposal based on the three-tracks. GIS is a computer-based analytical mapping technology that is rapidly becoming the cornerstone for conservation planning at many different spatial scales.
The proposed work plan called for the analysis to be focused at the 1:100,000-map scale using the best available data. While the 1:100,000 remained our target planning scale, we incorporated larger scaled data (e.g., 1:24,000) wherever possible. Doing so allowed for much more meaningful and reliable analyses. One of the greatest challenges throughout this project was evaluating and integrating the various data layers acquired from numerous sources.
The purpose of this project was to create a GIS-based model that identifies specific focal areas throughout the range of the redwoods. Focal areas were defined as zones that offer the best conservation opportunities for long-term protection and maintenance of the redwood ecosystem based on current conditions. GIS was utilized because of its spatially explicit architecture and advanced analytical capability.
This model was produced for Save-the-Redwoods League as part of their overall Master Plan – an organizational blueprint for protecting the redwood ecosystem. More specifically, this model was intended to help the League target their future proactive conservation planning efforts more effectively as part of their overall conservation mission while supplying a broader organizational tool that could be shared with its conservation partners in the region.
