Final Report: Anticipating Forest Vulnerability to Fire-Catalyzed Ecosystem Change Forests in the western US are increasingly impacted by climate change. Warm, dry conditions associated with climate change both increases fire activity in western forests and make it more difficult for forests to recover after wildfires. If forests fail to recover, they may shift to non-forest ecosystems like grasslands or shrublands. It is important to understand where fires may result in the loss of forests because forests provide a variety of ecosystem services, including carbon storage, water regulation and supply, and biodiversity. Western forests are also integral for the timber industry and valued for their recreation opportunities, which can also support local economies. The goal of this project is to identify... Categories: Publication; Types: Citation Sagebrush and Climate Change North Central Climate Adaptation Science Center Workshop Report The North Central Climate Adaptation Science Center’s (NC CASC) Sagebrush and Climate Change Workshop occurred on August 20 and 21, 2024 at the University of Colorado Boulder, the NC CASC’s university host. The workshop convened experts and partners from a range of agencies, institutions, and geographies to discuss research and synthesis needs in the eastern sagebrush biome in Montana, Wyoming, and Colorado. The workshop was organized to promote discussion and gather input from experts, practitioners and stakeholders/rights holders to inform NC CASC’s science synthesis and research efforts on social-ecological transformation in the eastern sagebrush biome (WY, CO, MT) driven by climate change and other anthropogenic... Categories: Publication; Types: Citation Water-level changes impact angler effort in a large lake: Implications for climate change Climate change is expected to influence aquatic habitats and associated fish populations, yet we know little about the impact on recreational anglers. Our goal was to explore whether interannual fluctuations in waterbody surface area and other explanatory variables could be used as indicators of changes in angler fishing effort. Our approach leveraged a combination of remotely sensed waterbody surface area, environmental and fish population data, and onsite angler survey monitoring data for Devils Lake, North Dakota, USA during the open-water fishing period (May 1st to August 31st) for 9 years (1992–2021). The information was used to develop a dynamic waterbody size-angler effort model. Changes in waterbody surface... Categories: Publication; Types: Citation Final Report: Promoting Climate Resilience and Soil Health in Northern Rockies Grasslands Through Bison and Cattle Grazing Management: Weaving Together Indigenous and Western Science The goal of this project was to support efforts by the Blackfeet Nation in Montana to manage their lands in ways that promote climate and cultural resilience and improve grassland and soil health. One strategy for building such resilience is to utilize strategic management of grasslands and grazing activities as a “natural climate solution”. This includes the restoration of free-ranging bison to grassland landscapes and the management of livestock in ways that approximate wild bison grazing behavior, as well as other practices that can support revitalized and resilient grassland ecosystems. To support strategic grassland and grazing management decisions on Blackfeet lands, we synthesized information on bison and... Categories: Publication; Types: Citation, Report Data and code from: Western larch regeneration more sensitive to wildfire-related factors than seasonal climate variability To understand the impacts of changing climate and wildfire activity on conifer forests, we studied how wildfire and seasonal post-fire climate conditions influence western larch (Larix occidentalis) regeneration across its range in the northwestern US. We destructively sampled 1651 seedlings from 57 sites within 32 fires that burned at moderate or high severity between 2000 and 2015, and which were within 100 m of reproductively mature western larch, were sampled in 2021 and 2022 (i.e. the fires burned between 2000-2015 and we sampled the sites 6-22 years postfire). Using dendrochronological methods, we estimated germination years of seedlings to calculate annual recruitment rates. We used boosted regression trees...

However, these valuable ecosystems present unique challenges to climate change adaptation (actions in response to environmental change and its effects in a way that seeks to reduce harm) due to their rugged and remote characteristics. Within this context, we summarized literature on climate change impacts and adaptation actions across U.S. Rocky Mountain high-elevation ecosystems to address the important question: What are the knowledge gaps for climate change responses within this ecosystem that limit the ability of natural resource managers to perform successful climate change adaptation?...
