Monarch butterfly (Danaus plexippus plexippus) populations across the continent have dropped precipitously over the last 30 years, especially those found west of the Rocky Mountains. In 2018 and 2019, it was estimated that less than 30,000 individuals make up the western population of monarchs, representing the lowest estimates on record and less than one percent of 1980s-1990s population levels. An analysis of annual and seasonal data from 1980-2017 showed monarch butterflies overwintering in coastal California have declined more quickly than monarch overwintering in Mexico, and declines were most strongly associated with losses and degradation of overwintering habitat. To inform restoration of the overwintering...
FY2013This project retrieves four years of data from over 200 temperature sensors nested within 28 sites across ~40 million hectares of the hydrographic Great Basin. The sensors span all major aspects and up to 700 m of elevation within sites, and occur in numerous management jurisdictions in 18 mountain ranges plus other areas not in ranges. This project: Quantifies the variability of climate at micro-, meso-, and macroscales across the Basin, and across diel, seasonal, and interannual periods. Informs management and conservation efforts, in terms of helping calibrate and refine the climatic stage upon which all biological actors and efforts hinge (Beier and Brost 2010). Feeds into other bioclimatic and wildlife...

Incorporating climate change considerations into land management and species conservation remains challenging for natural resource managers, because other stressors such as drought or invasive species currently have a larger impact. Thus, it is often difficult to prioritize long-term goals when resources for the immediate needs of species are already difficult to secure. This project aims to combine the latest decision science with climate change refugia modeling to create a novel decision-framework that emphasizes a collaborative approach to complex management issues, which aims to bridge the gap between managing for current priorities and long-term climate change adaptation. In doing so, this framework will be...

Natural resource managers are confronted with the pressing challenge to develop conservation plans that address complex ecological and societal needs against the backdrop of a rapidly changing climate. Climate change vulnerability assessments (CCVAs) provide valuable information that helps guide management and conservation actions in this regard. An essential component to CCVAs is understanding adaptive capacity, or the ability of a species to cope with or adjust to climate change. However, adaptive capacity is the least understood and evaluated component of CCVAs. This is largely due to a fundamental need for guidance on how to assess adaptive capacity and incorporate this information into conservation planning...

Abstract (from Conservation Biology): Adaptive capacity (AC)—the ability of a species to cope with or accommodate climate change—is a critical determinant of species vulnerability. Using information on species’ AC in conservation planning is key to ensuring successful outcomes. We identified connections between a list of species’ attributes (e.g., traits, population metrics, and behaviors) that were recently proposed for assessing species’ AC and management actions that may enhance AC for species at risk of extinction. Management actions were identified based on evidence from the literature, a review of actions used in other climate adaptation guidance, and our collective experience in diverse fields of global-change...

Abstract (from Conservation Science and Practice): Climate change uncertainty poses serious challenges to conservation efforts. One emerging conservation strategy is to identify and conserve climate change refugia: areas relatively buffered from contemporary climate change that enable persistence of valued resources. This management paradigm may be pursued at broad scales by leveraging existing resources and placing them into a tangible framework to stimulate further collaboration that fosters management decision-making. Here, we describe a framework for moving toward operationalizing climate change refugia conservation at an ecoregion scale with an analysis for the Sierra Nevada ecoregion (CA, USA). Structured...

Abstract (from Conservation Science and Practice): Resource managers have rarely accounted for evolutionary dynamics in the design or implementation of climate change adaptation strategies. We brought the research and management communities together to identify challenges and opportunities for applying evidence from evolutionary science to support on-the-ground actions intended to enhance species' evolutionary potential. We amalgamated input from natural-resource practitioners and interdisciplinary scientists to identify information needs, current knowledge that can fill those needs, and future avenues for research. Three focal areas that can guide engagement include: (1) recognizing when to act, (2) understanding...

Worldwide, many species are responding to ongoing climate change with shifts in distribution, abundance, phenology, or behavior. Consequently, natural-resource managers face increasingly urgent conservation questions related to biodiversity loss, expansion of invasive species, and deteriorating ecosystem services. We argue that our ability to address these questions is hampered by the lack of explicit consideration of species’ adaptive capacity (AC). AC is the ability of a species or population to cope with climatic changes and is characterized by three fundamental components: phenotypic plasticity, dispersal ability, and genetic diversity. However, few studies simultaneously address all elements; often, AC is confused...

A primarily stream-dwelling and obligate stream-breeding species, the foothill yellow-legged frog (FYLF) has declined from over half of its historical range, and a listing decision under the U.S. Endangered Species Act will likely be made in December 2021. Recent analyses suggest that the Southwestern California (SWC) clade is the most genetically unique and at the highest risk due to stressors in its geography, revealing the urgency of addressing the conservation of this clade. The rapid extirpation of some FYLF populations from the Central California Coast may have resulted from chytrid fungus. Therefore, strategic translocations from the remaining populations along the Central California Coast now could help...
California has a broad diversity of forest ecosystems and associated wildlife, which are facing complex conservation challenges due to the increase in the frequency, severity, and size of fire outbreaks throughout the state. Although these ecosystems are fire adaptive, these catastrophic fires burn with such high severity that they destroy complete forest stands and kill off the seed bank needed for natural forest regeneration. One of the primary mechanisms for reducing the threat of high severity fires is fuel management treatments to reduce the understory and prevent damaging crown fires from occurring. Increasingly federal, state, and private entities are coordinating fuel management projects across the patchwork...
Climate change adaptation research has made major advances over the last decade. For example, much is known about the impacts of climate change, many novel adaptation planning approaches have been developed, decision tools have become ubiquitous, and many novel adaptation options have been proposed. However, additional research is needed to demonstrate how these adaptation planning schemes can translate to implementation on the ground. The area in and around the Yosemite and Sequoia National Parks in Southern Sierra Nevada serve as ideal natural laboratories to study the impacts of climate change and the effectiveness of various on-the-ground forest treatments and restoration designs. Southern Sierra Nevada faces...

California’s Central Valley habitats will continue to be influenced in the future by factors including changing land use, water availability, and population growth. Water scarcity and droughts will increasingly challenge wetland managers in the Central Valley. Thus, decisions on where to implement restoration and conservation projects today would benefit by considering plausible future landscape scenarios to ensure that restoration projects implemented now, continue to have value for decades to come. Recent work has developed spatially-explicit land use and climate change scenarios for Central Valley wetlands. Building on these existing efforts, this project will assess site-specific suitability of wetland habitat...
The Bureau of Land Management (BLM) manages the largest area of public lands in the United States. Decision-making on BLM lands is complex because managers have to balance diverse, sometimes conflicting, resources, uses, and values. Land managers are more likely to achieve long-term land management goals and balance multiple desired uses and values across public landscapes when their decisions are informed by the best available science, including climate science. Strengthening the use of science and climate information in federal decision making is a priority for the current administration and for federal agencies, including the BLM. The Climate Adaptation Science Centers are committed to developing climate science...
