Changing climate conditions such as increasing droughts, floods, and wildfires, hotter temperatures, declining snowpacks, and changes in the timing of seasonal events are already having an impact on wildlife and their habitats. In order to make forward-looking management decisions that consider ongoing and future projected changes in climate, managers require access to climate information that can be easily integrated into the planning process. Co-production, a process whereby scientists work closely with managers to identify and fill knowledge gaps, is an effective means of ensuring that science results will be directly useful to managers. Through a multi-phase project, researchers are implementing co-production...

Grasslands in the northern Great Plains are important ecosystems that support local economies, tribal communities, livestock grazing, diverse plant and animal communities, and large-scale migrations of big game ungulates, grassland birds, and waterfowl. Climate change and variability impact how people and animals live on and interact with grasslands, and can bring more frequent droughts, fires, or new plant species that make managing these landscapes challenging. Understanding how climate change and variability will impact grassland ecosystems and their management in the 21st century first requires a synthesis of what is known across all of these scales and a gap analysis to identify key areas of focus for future...

In many places around the world, spring events, like warming temperatures, are coming earlier and fall events are coming later than they have in the past. These changes have implications for the phenology, or the timing of natural life events (e.g. the timing of plant flowering in Spring or leaves falling in Autumn), of many plant species. However, not all species and regions are changing at the same rate, which can lead to mismatches (e.g. between the emergence of plants and pollinators in early spring). Many interactions in nature depend on timing and, as such, phenology affects nearly all aspects of the environment, including the abundance, distribution, and diversity of organisms, ecosystem services, food webs,...

Pinyon pine woodlands are among the most widespread and iconic vegetation types in the western United States and support recreation, resource extraction, grazing, and cultural enrichment. However, severe drought conditions have recently caused dramatic mortality of pinyon pines, creating concern about the long-term impact of increasing aridity on the viability of pinyon woodlands. Ecological transformations, or regime shifts, are rapid reorganizations of an ecosystem’s species composition, governing processes, and functions. The goal of this project is to investigate ecological transformation across the Western U.S, characterize the environmental drivers of these changes in vegetation, and apply those insights...

As elevation increases, both temperature and moisture availability decrease. In many parts of the world, this decrease in temperature is a limiting factor for vegetation—at certain elevations, the temperature becomes too cold for plants to survive. However in the tropics, moisture availability may play a more important role than temperature in determining the altitude at which forests can grow. For example on Haleakalā, a volcano on the Hawaiian Island of Mauʻi, the forest line is not found at the same elevation everywhere, as you would expect if it were controlled by temperature. Rather, the forest line is highest in the wetter eastern-most end and lower on the drier, western end of the volcano. Research also...

Drought events have cost the U.S. nearly $245 billion since 1980, with costs ranging from $2 to $44 billion in any given year. However, these socio-economic losses are not the only impacts of drought. Ecosystems, fish, wildlife, and plants also suffer, and these types of drought impacts are becoming more commonplace. Further, ecosystems that recover from drought are now doing so under different climate conditions than they have experienced in the past few centuries. As temperature and precipitation patterns change, “transformational drought”, or drought events that can permanently and irreversibly alter ecosystems – such as forests converting to grasslands – are a growing threat. This type of drought has cascading...

The NC CASC supports co-produced actionable science, data-intensive discovery, and open science to support tribal, federal, state, and local natural resource managers and decision-makers in the North Central region, which serves Colorado, Wyoming, Montana, North Dakota, South Dakota, Kansas and Nebraska. NC CASC is hosted by the University of Colorado Boulder (CU Boulder) within the Cooperative Institute for Research in Environmental Sciences , and is a partnership between CU Boulder, the U.S. Geological Survey, and five consortium partners: University of Montana; South Dakota State University; Conservation Science Partners; Wildlife Conservation Society; and Great Plains Tribal Water Alliance. During the period...
