Plants

Climate change is impacting soil and vegetation management practices, ecosystem function, human health, cultural resiliency, and economic well-being. CASC-funded projects inform vegetation and ecosystem restoration and shifting land management practices to help conserve important native plant species. Explore our science with plants below.

Post-Fire Conifer Regeneration Under a Warming Climate: Will Severe Fire Be a Catalyst for Forest Loss?

The Southwest U.S. is experiencing hotter droughts, which are contributing to more frequent, severe wildfires. These droughts also stress vegetation, which can make it more difficult for forests to recover after fire. Forest regeneration in burned areas may be limited because seeds have to travel long distances to recolonize, and when they do arrive, conditions are often unfavorably hot and dry. C

Relocating Plants for Conservation and Restoration: Developing a Risk Assessment Framework

There is growing interest in the facilitated movement of plants as a means of conserving or restoring species and habitats, as climate conditions and management goals change. For example, plants might be relocated to support pollinator conservation or the restoration of prairies. Some land managers, in an effort to be proactive in the face of changing environmental conditions, are also considering

Supporting Local Agricultural Planning and Adaptation in Alaska

Agriculture in Alaska is climate-limited. Factors such as low heat energy, short growing seasons, and cold winters prevent the survival of many crops. While considerable research has gone into assessing how to overcome some of these limitations, results suggest that climate change is already altering the equation, and will likely continue to do so. Some research suggests crop production for some v

The Future of Culturally Important Species in North America

Thousands of plant and animal species are culturally important to the Indigenous peoples of North America. Global change is leading to major shifts in the abundance, distribution, and life history of these species, with concomitant effects on their value to the peoples for whom they are most culturally important. While a number of studies have begun to explore the futures of culturally significant

Understanding Fire-caused Vegetation Type Conversion in Southwestern Conifer Forests under Current and Future Climate Conditions

Fire size, frequency, overall area burned, and severity are increasing across many vegetation types in the southwestern U.S. In many cases, large contiguous areas are burning repeatedly at high severity, triggering vegetation type conversions (VTC), where once-dominant coniferous forests fail to return to their pre-fire state, often transitioning to shrub- or grass-dominated systems. Loss of these

Assessing Climate Impacts and Adaptation for Biodiversity and Natural Resources in San Diego County

The Mediterranean ecosystems of southern California are some of the most ecologically diverse systems in the world. The diversity of plants and animals, as well as high rates of endemism, make the area a biodiversity hotspot. High diversity in plant and animal species contributes greatly to the health and productivity of ecosystems, and plays an important role in the local and state economy (e.g.

Climate Change Impacts on Invasive Species in the Northwest: A Synthesis and Path Forward

Invasive species have increasingly severe consequences for ecosystems and human communities alike. The ecological impacts of invasive species are often irreversible, and include the loss of native species and the spread of disease. Implications for human communities include damaged water transportation systems, reduced crop yields, reduced forage quality for livestock, and widespread tree death -

Climate Extremes and Ecological Impacts to California Estuaries

Estuaries are located at the interface where rivers meet the sea, creating unique ecosystems with complex physical and biological processes. Coastal wetlands provide essential ecosystem services to people, including flood protection from high tides and storm surges, commercial fisheries, carbon sequestration, improved water quality, and wildlife food and habitat. Coastal wetlands are also home to

Climate Impacts on the Locations and Availability of Traditional Food Sources from Native Northwestern Shrubs

Fruit-producing shrubs such as huckleberries, salal, and hazelnut are an important component of social history and traditional tribal diets in the Pacific Northwest. The fruits of these shrubs are also an important food source for foraging wildlife and pollinators, and serve as the basis for both non-tribal harvesting and small-scale commercial operations. Among land managers and tribes, there is

Improving Projections of Wildlife and Landscapes for Natural Resource Managers

Managing natural resources is fraught with uncertainties around how complex social-ecological systems will respond to management actions and other forces, such as climate. Modeling tools have emerged to help grapple with different aspects of this challenge, but they are often used independently. The purpose of this project is to link two types of commonly-used simulation models (agent-based models

Spoilt for Choice: A Review and Evaluation of Downscaled Climate Data for the Pacific Northwest

In order to assess and understand the potential impacts of climate change on important natural resources, managers, planners, and decision-makers need climate information at a local or regional scale. In general, Global Climate Models (GCMs) provide data at coarser scales than most natural resource managers need but Regional Climate Models (RCMs) are starting to deliver finer scale results. The pr

The Impacts of Climate Change on Phenology: A Synthesis and Path Forward for Adaptive Management in the Pacific Northwest

Phenology, or the timing of the annual cycles of plants and animals, is extremely sensitive to changes in climate. We know that plants and animals may adjust the timing of certain phenological events, such as tree flowering or migration, based on changes in weather. However, it’s important that we also understand how the timing of phenological events is changing over longer time frames, as climate
