The U.S. Forest Service, Oregon State University, and Conservation Biology Institute have collaboratively developed the Seedlot Selection Tool to help forest managers match tree seed collections (called seedlots) with planting sites to help ensure the resilience of forests in a changing climate.
The Seedlot Selection Tool (or SST) is a free web-based decision-support tool that can be used to map planting locations based on either current climate data or a range of possible future climates across the conterminous U.S. and Mexico. Users can select a tree species, a climate scenario and relevant climate variables for the species, and other parameters to identify sources of seedlots appropriate for planting on a particular site or planting sites that are appropriate for planting seedlings from a particular seedlot. A valuable planning and educational tool, the SST helps explore possible future conditions, assess risk, and plan potential responses as part of a decision about which seedlot seedlings will be best adapted to a particular planting site in the future.

The SST was spearheaded by Glenn Howe at Oregon State University and Brad St. Clair at the USFS Pacific Northwest Research Station and developed by Nikolas Stevenson-Molnar, Brendan Ward, and Dominique Bachelet at CBI. Recently the USDA Climate Hub and USFS Region 6 staff worked with CBI to develop a step-by-step Guidebook and Video Tutorial for the Seedlot Selection Tool for Region 6 Silviculturists. These materials are useful to anyone who wants to learn about the use of this resource.

Support for the SST came from the USFS, OSU, CBI, and the USDA Northwest Climate Hub.
CBI is providing scientific and technical support to Greenpeace Canada and AV Terrace Bay as they work together to maintain the ecological integrity of the Kenogami-Ogoki Forests in Ontario, Canada while providing a sustainable wood supply to the AV Terrace Bay mill and protecting cultural values of First Nations peoples.
There are two major, interrelated components of the project. First, CBI is examining a series of important aspects of woodland caribou conservation in the region, which has been a major focus throughout boreal Canada for a number of years as ongoing development is continually eroding woodland caribou habitat resulting in serious declines in some populations. Using data provided by the Ontario government, CBI is attempting to identify key caribou activity areas, regional movement patterns, and crucial habitat.
CBI is also creating a series of risk-based protected areas scenarios by defining areas of high landscape value and high biological value. High biological value is determined by considering representation of native ecosystems, overall forest values, concentrations of rare species, wetlands, and vital woodland caribou habitat.
Upon development of the scenarios, CBI will facilitate a discussion to review the trade-offs of the different scenarios between AV Terrace Bay and Greenpeace Canada, using Data Basin to support the discussion given the spatially explicit nature of the effort. In the end, the hope is to forge a land management agreement between the two parties that will allow for sustained economic development of the forest resources while protecting the ecological integrity of the region (including woodland caribou viability) and cultural values of the local First Nations peoples.
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.

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.
The fisher (Martes pennanti) is a large member of the weasel family associated with dense, structurally complex, low- to mid-elevation forests. Remaining populations in the western U.S. are small, disconnected from one another, and threatened by habitat modification and fragmentation. In 2008 fishers occupied less than half their historic range, having apparently been extirpated from the central and northern Sierra Nevada. A small population persist in the southern Sierras, south from Yosemite National Park to the vicinity of the Greenhorn Mountains in southern Tulare County.
The Conservation Biology Institute (CBI) was commissioned by Region 5 of the U.S. Forest Service to compile all available data on fisher populations and habitat in the southern Sierra Nevada, assess their current status, and predict how they are likely to respond to various alternative forest management actions, as well as unmanaged events such as wildfires, drought, or bark beetle outbreaks. The project was designed to create a scientifically credible set of habitat maps and estimates of fisher population size and distribution in the southern Sierra Nevada based on current conditions and likely future change under a range of alternative scenarios.
A group of independent science advisors was assembled to oversee the technical aspects of the analysis and ensure use of best available science. Stakeholder groups were kept informed via stakeholder representatives from the timber industry, conservation organizations, the US Fish and Wildlife Service, California Department of Fish and Game, and the various National Parks and Forests in the studya are. CBI worked closely with experts from the Pacific Southwest Reserach Station and Region 5 to ensure that the analysis accurately reflected proposed forest management actions.
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:
- Conversion due to urbanization, agriculture, ranching, and mining
- Commercial exploitation of timber and wood pulp
- Local exploitation for firewood
- Human-altered distribution regimes (e.g. fire)
- Introduction of exotic species
- Construction of infrastructure facilities – particularly roads
Consequently, long-term forest conservation depends, at least in part, on large-scale forest restoration. The purpose of this report is threefold:
- Discuss the concept of forest restoration form a conservation biology perspective
- 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
- Place forest restoration within the larger context of worldwide forest conservation
