CBI is working with Utah’s Division of Wildlife Resources (DWR) and The Bureau of Land Management to develop decision support models to inform current conservation initiatives in Utah and throughout the Colorado Plateau ecoregion. Based on previous REA (Rapid Ecoregional Assessment) work, CBI is updating the existing terrestrial landscape and aquatic intactness models for the Colorado Plateau ecoregion as well as updating habitat profiles for a number of identified conservation elements of interest (largely native species and communities). CBI is extending the models to cover the entire state of Utah as well as fine-tuning the models to be more effective at answering different management questions over smaller geographic areas.
CBI is also updating a previously created climate stress logic model with the most recent climate data from the 5th Intergovernmental Panel on Climate Change (IPCC) report as well as carryout some new analyses. For example, mapping potential climate refugia – areas where plants and animals may find shelter from changes in climatic conditions. CBI is also examining past and future climate variability to model climate velocity, which is the speed along the Earth’s surface needed to maintain constant climate conditions with the rationale being that species survival may depend as much on keeping pace with moving climate as the climate’s ultimate persistence. Results of the climate modeling will illustrate at the landscape level the degree to which locations in the landscape will be impacted by climate stress over the next century and help estimate the likelihood that certain species will survive shifting suitable habitat conditions.

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).

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.
Island foxes (Urocyon littoralis) inhabit the six largest Channel Islands off the coast of southern California, with a separate subspecies recognized on each island: San Miguel Island fox (U. l. littoralis), San Nicolas Island fox (U. l. dickeyi), San Clemente Island fox (U. l. clementae), Santa Catalina Island fox (U. l. catalinae), Santa Rosa Island fox (U. l. santarosae), and Santa Cruz Island fox (U. l. santacruzae). Due to their limited geographic distribution and small population sizes, foxes on all six islands have been listed as Threatened by the State of California, and all subspecies except those on San Nicolas and San Clemente have been listed as Endangered by the U.S. Fish and Wildlife Service due to recent precipitous population declines and high risk of extinction.
Due to the persistent high risk of this island species, robust monitoring of fox populations and their threats is a key component of recovery and long-term management. In response to a request from the Recovery Coordination Group of the Island Fox Integrated Recovery Team, the Conservation Biology Institute was commissioned by The Nature Conservancy, with additional funding from the Catalina Island Conservancy, to develop a monitoring framework for five subspecies of island fox on San Miguel, San Nicolas, Santa Catalina, Santa Rosa, and Santa Cruz islands. A monitoring framework previously developed for the U.S. Navy for San Clemente Island foxes (Framework Monitoring Plan for the San Clemente Island Fox, 2006), in addition to years of monitoring and research on all six islands, provided the foundation for the current multi-island monitoring framework. This document thus represents the first comprehensive synthesis of monitoring data, objectives, and protocols across multiple Channel Islands with foxes.
This report describes the considerations and approaches used to identify specific monitoring objectives, determine parameters to address these objectives, and develop protocols to measure these parameters. It presents illustrative island-specific examples of monitoring scenarios designed to address current monitoring objectives, but with different levels of effort and resulting precision. Recommendations are offered as guidelines with some built-in flexibility to account for on-the-ground feasibility. It is expected that island managers will tailor and adapt protocols for on-the-ground use, based on their resources and priorities, understanding that there is generally a trade-off between monitoring intensity and information value, and that future advances in our knowledge of fox ecology and in the development of field and analytical techniques may result in adaptation of this framework monitoring protocol.
CBI led the development of a science-based adaptive habitat management plan for the approximately 3,000-acre Ramona Grasslands Open Space Preserve in central San Diego County. The Ramona Grasslands are a regionally important conservation area, supporting a variety of target resources, including vernal pools and rare vernal pool species, Stephens’ kangaroo rat, wintering and breeding raptors, riparian habitats and arroyo southwestern toads, and native grasslands. The Ramona Grasslands are grazed by cattle, which maintain habitat suitability for some species but adversely affect other natural resources. CBI initially partnered with The Nature Conservancy to develop a Framework Management Plan for the Grasslands, which laid out a scientific basis for implementing management activities, describe experimental manipulations to increase our understanding of the dynamics of the system, and to develop a biological monitoring program to assess changes in resource states.
CBI then worked with the County of San Diego Department of Parks and Recreation and their contractors to develop a detailed description of baseline conditions in the Ramona Grasslands and specific management and monitoring recommendations (Area Specific Management Directives) that were derived from the Framework Management Plan. Development of the management plan was preceded by a 2-year baseline field monitoring program that was coordinated by CBI. The Area Specific Management Directives proposed an adaptive grazing strategy to balance resource needs and optimize habitat quality across the preserve. Monitoring activities proposed by the management plan included surveys of grassland, vernal pool, and riparian plants; characterization of stream channel geomorphology and water quality; and avian, small mammal, amphibian, and fairy shrimp surveys.
