The National Park Service is responsible for managing livestock grazing on 94 locations across the country and several grazing management planning efforts for this work are underway. However, there is a recognized need to update grazing management plans to address potential future effects of climate change on related resources and practices. This is the second phase of a project that is using scenario planning (a strategic planning technique used to inform decision-making in the face of uncertain future conditions) to support grazing management at Dinosaur National Monument. In the first phase of the project (Integrating Climate Considerations into Grazing Management Programs in National Parks), the research team...

Steep, mountainous watersheds, dramatic climate gradients, and tight links between the land and sea are common features of both the Pacific Islands and Southeast Alaska. In these "ridge-to-reef" and “icefield-to-ocean" ecosystems, environmental changes that occur at higher elevations have downstream impacts on the waters below. Today, these two ecosystems are undergoing changes in climate that are significantly impacting the terrestrial, freshwater, and coastal ecosystems that communities rely on for food, water, recreation, and tourism. For example, changing weather patterns are leading to more frequent and severe extreme storms, atmospheric rivers, droughts, and heat waves. Communities in both regions have deep...

This dataset represents current management alternatives for maintaining whitebark pine (Pinus albicaulis) in the Greater Yellowstone Ecosystem. This data was developed for use in a landscape simulation modeling study aimed at evaluating how well alternative management strategies maintain whitebark pine populations under historical climate and future climate conditions. For the study, we developed three spatial management alternatives for whitebark pine in the Greater Yellowstone Ecosystem representing no active management, current management, and climate-informed management. These management alternatives were implemented in the simulaton model FireBGCv2 under historical climate and three future climate change scenarios...

Even when faced with uncertainty about future climate conditions, resource managers are tasked with making planning and adaptation decisions that impact important natural and cultural resources. Species distribution models are widely used by both researchers and managers to estimate species responses to climate change. These models combine data on environmental variables (e.g., temperature, precipitation) with field samples of a species’ presence, absence, and/or abundance to project and visualize potential habitat of the species across space and time. However, species distribution modeling software previously developed and supported by USGS (the Software for Assisted Habitat Modeling [SAHM] package for VisTrails)...

Some areas of the U.S. Affiliated Pacific Islands (USAPI) are experiencing a decline in precipitation and streamflow and an increase in the number of severe droughts. These changes can have wide-reaching implications, affecting the water supply, native vegetation and wildlife, wildfire patterns, and the spread of invasive species. As ecosystems become altered by invasive species and as particularly hotter, more variable climates emerge, it is critical that scientists produce locally relevant, timely, and actionable science products for managers to prepare for and cope with the impacts of drought. Simultaneously, it is important that managers are able to both access this information and shape the types of data products...

The US Virgin Islands are vulnerable to sea level rise, intense storms, and unpredictable rainfall brought by climate change. These changes influence the health of freshwater streams (known as “ghuts”), sedimentation, erosion and water quality (“grit”), as well as aquatic communities and ecosystems (“gills”) that are unique to the islands and important for indigenous peoples’ heritage, local fishermen, tourism, and more. However, the US Virgin Islands have limited water resource data, and the data that exist are scattered across sources, creating an obstacle for adapting water management strategies. Preparing for and responding to climate change requires understanding the threats, priorities, solutions, and funding...

In 2020, Governor Edwards of Louisiana issued two executive orders: establishing the Climate Initiatives Task Force to develop the state’s first ever Climate Action Plan to reach net zero greenhouse gas emissions by 2050 and to enhance coastal resilience in the state. Louisiana’s coastal wetlands and natural lands are of vital importance not just for hurricane protection, health and wellbeing, and natural resources, but also for carbon sequestration (i.e. capturing and storage of carbon from the atmosphere). Enhancing natural carbon sinks (i.e. ecosystem that stores more carbon than it releases) to offset greenhouse gas emissions is a critical step for Louisiana to achieve its net zero goals. Coastal wetlands have...
