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.

CBI conservation biologists Jerre Stallcup, Patricia Gordon-Reedy, and Jessie Vinje are working with the San Diego National Wildlife Refuge (NWR), U.S. Bureau of Land Management (BLM), and California Department of Fish and Wildlife (CDFW) to develop methods for restoring grasslands of historic ranchos in southern San Diego County.  Together, we will develop an adaptive management plan with the objective of replicating this process on other conserved lands in southern California.

In the early to mid-1990s the Otay-Sweetwater area of San Diego County was comprised mostly of large cattle ranches; these were formerly Mexican land grants established in the early 1800s. Because of their size, resources, and location near large public land holdings of BLM and CDFW, these properties were excellent candidates for acquisition as part of the San Diego Multiple Species Conservation Program (MSCP), a proactive and ecosystem-based conservation initiative launched in 1991 and continuing today. However, the properties also held special appeal to developers for many of the same reasons.

The San Diego NWR was thus born from unprecedented cooperation and partnership among local, state, and federal agencies, developers, and private conservation groups.  This area, where CBI is now working, lies within the largest expanse of undeveloped land in the MSCP planning area, supporting some of the last remaining coastal habitats of southern California.  Because of the concentration and global significance of its sensitive habitats and endangered species, and its high habitat integrity and proximity to other conserved lands, this unfragmented landscape is one of the highest priorities for conservation in California.

CBI used detailed habitat assessments and conceptual models to design cost-effective ways of controlling exotic grasses to benefit targeted grassland species (Otay tarplant, Quino checkerspot butterfly, and burrowing owl), testing different mechanical and chemical methods informed by past management practices.  We will restore native grasslands and forblands suitable for these and other rare species.  Coordination among land managers will allow us to conserve costs through economies of scale in contracting and implementing multi-year management actions with the objective of expanding the coverage of management actions based on the results of this project.

This project is providing spatially explicit scientific foundations for forest management recommendations to sustain and enhance populations of four imperiled carnivores in the Sierra Nevada of California:  marten (Martes americana), fisher (Martes pennanti), wolverine (Gulo gulo), and Sierra Nevada red fox (Vulpes vulpes necator).  The recommendations focus on enhancing resiliency of existing populations over the next 15-20 years, and assessing strategies for adaptation to climate change in the longer term.

Products include maps depicting habitat value and distribution for each species, lands important to maintaining population connectivity and movement potential between habitat areas, and lands important to accommodating shifts in distribution under climate change.  These maps will serve as foundations for spatially explicit conservation, management, and restoration recommendations, which can be incorporated into National Forest Management Plans and other land use and management plans.

This project will produce decision-support maps and tools to support an Interagency Fisher Biology Team in developing and implementing a Conservation Strategy for the west coast fisher Distinct Population Segment (DPS)–a Candidate for listing under that Endangered Species Act that stretches from southern British Columbia through Oregon, Washington, and California.  The Interagency Fisher Team includes representatives of the US Fish and Wildlife Service, US Forest Service, and other Federal, State, and Provincial agencies with an interest in species conservation and forest management.

CBI will prepare maps, analyses, and other decision-support tools, including habitat value, habitat connectivity, and population distribution maps for the DPS under current conditions, and an assessment of climate-change effects on fisher habitat and populations in the future.  These types of spatially explicit decision-support tools are needed to inform conservation planning and adaptive management to sustain and restore habitat value and fisher populations within the fisher DPS.

As the Earth’s climate changes, many plant and animal species are reacting by shifting their geographic ranges. As a result, resource managers are now faced with the challenge of developing and implementing strategies that will support wildlife adaptation to climate change. The sheer magnitude and diversity of models and data that can be applied to climate impact analyses and adaptation strategies can often be confusing to many users.

Recognizing a need for clarity within this field, the Yale School of Forestry and Environmental Sciences convened a working group of the nation’s leading conservation biologists, modelers, and policy makers to develop a guidance tool for integrating natural adaptation strategies into the context of natural resource planning and policymaking. The tool, The Yale Mapping Framework (www.databasin.org/yale), assists resource managers in selecting the assessment and modeling strategies that are most relevant to their specific needs, helping to guide choices among the many tools, data, and methods that planners may use to implement their adaptation approaches in the face of a changing climate.

This report assesses potential impacts of feral pig populations in southern California (San Diego, Riverside, Imperial, and Orange counties) and Baja California, with an emphasis on San Diego County. We compiled information on the status of pigs in these areas from the literature and interviews with numerous individuals knowledgeable about feral pig populations, including a population recently introduced into San Diego County. We also reviewed available information on the potential impacts of feral pigs on natural resources, water systems, agriculture, and human health, and discussed the feasibility of various control and eradication options.

We developed population and habitat suitability models for feral pigs in San Diego County to examine the potential for numeric and geographic expansion following the recent introduction near El Capitan Reservoir. The models suggest that the population has the potential to grow rapidly and expand into large expanses of currently unoccupied habitat. Such expansion could harm natural biological resources, including riparian and oak woodland communities and numerous sensitive species. It is possible that populations could establish in such protected lands as Cuyamaca Rancho State Park and Volcan Mountain Preserve, as well as various wilderness areas. This could greatly diminish and possibly nullify large conservation investments already made in this region, including habitat restoration efforts. Finally, an expanding feral pig population in San Diego County could invade and cause grave damage in Baja California, where feral pig populations have not, to date, been reported.

In response to the environmental consequences of burning fossil fuels, particularly climate change, and rising energy prices, alternative energy sources are being actively sought throughout the world. Renewable energy sources can help to meet growing energy demands while reducing environmental costs. One widely promoted alternative is biomass energy derived from dedicated biomass crops, as well as from forest and fire management activities. While biomass energy shows some promise as a clean, renewable, and domestic alternative to fossil fuels, it can conflict with critical ecological values and sustainability goals if not properly planned for and implemented.  In order to move toward ecological sustainability, biomass energy production must not degrade these important ecological values.  However, existing projections of available forest and shrubland biomass resources in the U.S. have not adequately taken these values into consideration.

The Natural Resources Defense Council (NRDC) commissioned CBI to evaluate the effect that ecological constraints would have on estimates of forest and shrubland biomass resources available for energy production in California, as assessed by the California Energy Commission in 2005.  California, home to many biologically diverse and unique areas, has been a leader in developing biomass as a potential source of energy as the demand for electrical power continues to rise.  The current contribution from biomass to electrical power in California is very small, but current and future biomass resources could be effectively developed to contribute as much as 15 percent of electrical energy demands by 2020. Rapid development of biomass as an energy alternative in California and elsewhere without careful consideration of the overall environmental impact could help achieve climate change abatement goals on the one hand but devastate important biological and ecological values on the other.  Accounting for these effects is an initial step towards reducing the environmental impact and risk to important conservation values as biomass development planning and implementation moves ahead. Using available spatial datasets, CBI’s GIS-based analysis quantified and mapped the changes to the current forest and shrubland biomass estimates after accounting for ecological values, such as old growth forest and critical habitat, and the wildland-urban interface.

The IABIN Data Integration and Analysis Gateway (DIAG) is a gateway within Data Basin that provides a custom view of content in the system for IABIN users.  This gateway is intended to showcase the information produced by the 5 IABIN thematic networks: ecosystems, invasive species, pollinators, protected areas, and species & specimens.

IABIN was created in 1996 as an initiative of the Santa Cruz Summit of the Americas meeting of Heads of State. Steadily gaining momentum, there are now 34 countries in the Americas that have officially been named IABIN focal points.  Although endorsed by governments, NGOs, universities, museums, and the private sector all belong to and play important roles in IABIN.

IABIN will provide the networking information infrastructure (such as standards and protocols) and biodiversity information content required by the countries of the Americas to improve decision-making, particularly for issues at the interface of human development and biodiversity conservation. It is developing an Internet-based platform to give access to scientifically credible biodiversity information currently scattered throughout the world in different institutions, such as government organizations, museums, botanical gardens, universities, and NGOs.

The IABIN Secretariat is dedicated to the implementation of IABIN will support a technical standards development process, coordinate catalogues and directories (either centralized or distributed), manage communications including electronic mailing, lists and Web sites, coordinate efforts with other networks, support training for member countries and organizations, and support the efforts of IABIN nodes.

All content developed by IABIN is open and available for public use.

The World Wildlife Fund has identified over 200 ecoregions (the Global 200) recognized for their high conservation priority, and calls for concentrated conservation planning in these regions. Not surprisingly, forested ecoregions constitute the majority of the Global 200.

Humans associate a wide array of values with forests. Historically, human interaction with forests has been predominantly destructive. Among the most important of these include:

Consequently, long-term forest conservation depends, at least in part, on large-scale forest restoration. The purpose of this report is threefold:

  1. Discuss the concept of forest restoration form a conservation biology perspective
  2. Outline the ecological characteristics, technical constraints, socio-political and economic influences, and overall restoration principles relevant to the Global 200 major habitat types and associated realms
  3. Place forest restoration within the larger context of worldwide forest conservation
