As part of the State Wildlife Grant Fund, states are required to submit State Wildlife Plans (SWAPs) every 10 years detailing threats to habitats and species and conservation plans. However, incorporating climate change in SWAPs is voluntary, and capacity/expertise limitations at state agencies have resulted in varied and often only partial consideration of climate change impacts. In response, the MW CASC will conduct literature reviews to assess climate stressors and impacts to habitats and key species and to identify relevant adaptation actions for 13 different Level 2/3 EPA Ecoregions contained within the MW CASC area states. This work will provide a foundation for future habitat vulnerability assessments. ...

A sensitivity analysis of groundwater-recharge estimates from a water-budget model was completed for the islands of Oahu and Maui, Hawaii (Johnson and others, 2023). Results of the sensitivity analysis were used to quantify the relative importance of selected model parameters to recharge estimates for three moisture zones (dry, mesic, and wet) on Oahu and Maui. This shapefile contains the boundaries of the moisture zones and boundaries of the model subareas that were used in the model simulations for Oahu. The shapefile attribute information includes the names of the land-cover types assigned to model subareas and the mean annual recharge values determined for the model subareas for the baseline scenario of the...

This data collection consists of a synthetic stream network and associated catchments developed as the foundation for a Spatially Referenced Regressions on Watershed Attributes (SPARROW) dissolved-solids source and transport model for the Upper Colorado River Basin (UCRB). The SPARROW model requires a hydrologically connected representation of a stream network through which loads are transported from an upstream reach to the next reach downstream (Schwarz and others, 2006; Moore and others, 2004). Each stream reach or segment within this synthetic stream network has an associated local drainage area or catchment used to calculate catchment characteristics that may have an effect on loads being modeled. The synthetic...

Cheatgrass began invading the Great Basin about 100 years ago, changing large parts of the landscape from a rich, diverse ecosystem to one where a single invasive species dominates. Cheatgrass dominated areas experience more fires that burn more land than in native ecosystems, resulting in economic and resource losses. Therefore, the reduced production, or absence, of cheatgrass in previously invaded areas during years of adequate precipitation could be seen as a windfall. However, this cheatgrass dieoff phenomenon creates other problems for land managers like accelerated soil erosion, loss of early spring food supply for livestock and wildlife, and unknown recovery pathways. We used satellite data and scientific...

Maintaining the native prairie lands of the Northern Great Plains (NGP), which provide an important habitat for declining grassland species, requires anticipating the effects of increasing atmospheric carbon dioxide (CO2) concentrations and climate change on the region’s vegetation. Specifically, climate change threatens NGP grasslands by increasing the potential encroachment of native woody species into areas where they were previously only present in minor numbers. This project used a dynamic vegetation model to simulate vegetation type (grassland, shrubland, woodland, and forest) for the NGP for a range of projected future climates and relevant management scenarios. Comparing results of these simulations illustrates...

Natural resource managers and researchers often need long-term averages of historical and future climate scenarios for their study area yet may not have the resources to make these summaries. This project will provide high quality, detailed maps of historical and projected future climate and hydrologic conditions for California and a finer scale version for southern California. The project will also assess the feasibility of expanding these reference data to the southwestern US and identify the most suitable online data portals for the public to view and analyze the data in support of local initiatives. The map products can be used to assess the impacts of ongoing climate change and to develop climate adaptation...

In southwestern Colorado, land managers anticipate the impacts of climate change to include higher temperatures, more frequent and prolonged drought, accelerated snowmelt, larger and more intense fires, more extreme storms, and the spread of invasive species. These changes put livelihoods, ecosystems, and species at risk. Focusing on communities in southwestern Colorado’s San Juan and Gunnison river basins, this project will expand opportunities for scientists, land managers, and affected residents to identify actions that can support resilience and adaptation in the face of changing climate conditions. This project builds on the project “Building Social and Ecological Resilience to Climate Change in southwestern...

One of the biggest challenges facing resource managers today is not knowing exactly when, where, or how climate change effects will unfold. To help federal land managers address this need, the North Central CASC has been working with the National Park Service to pioneer an approach for incorporating climate science and scenario planning into NPS planning processes, in particular Resource Stewardship Strategies (RSS). These strategies serve as a long-range planning tool for a national park unit to achieve its desired natural and cultural resource conditions, and are used to guide a park’s full spectrum of resource-specific management plans and day-to-day management activities. To support adaptation planning within...

Climate change is causing an increase in the amount of forested area burned by wildfires in the western U.S. The warm, dry post-fire conditions of the region may limit tree regeneration in some areas, potentially causing a shift to non-forest vegetation. Managers are increasingly challenged by the combined impacts of greater wildfire activity, the significant uncertainty about whether forests will recover, and limited resources for reforestation efforts. Simultaneously, there has been an increased focus on post-fire reforestation efforts as tree planting has become a popular climate change mitigation strategy across the nation. Therefore, with increased interest and need, it is crucial to identify where varying...

Tribal resource managers in the southwest U.S. are facing a host of challenges related to environmental change, including increasing temperatures, longer periods of drought, and invasive species. These threats are exacerbating the existing challenges of managing complex ecosystems. In a rapidly changing environment, resource managers need powerful tools and the most complete information to make the most effective decisions possible. Traditional Ecological Knowledge has enabled Indigenous peoples to adaptively manage and thrive in diverse environments for thousands of years, yet it is generally underutilized and undervalued, particularly in the context of western scientific approaches. Traditional Ecological...

Natural and cultural resource managers across the country have begun to use a tool known as "scenario planning" to help prepare for climate change effects that may unfold in the future. In this process, scientific projections are used to identify different plausible, relevant, and divergent climate conditions for a particular area, and then through a participatory process, scientists and resource managers develop "scenarios" which describe the implications of these different conditions for resources and management. The North Central CASC has been working with the National Park Service (NPS) Climate Change Response Program (CCRP) to encourage and support national parks in incorporating climate science and scenario...
