A number of modeling approaches have been developed to predict the impacts of climate change on species distributions, performance and abundance. The stronger the agreement from models that represent different processes and are based on distinct and independent sources of information, the greater the confidence we can have in their predictions. Evaluating the level of confidence is particularly important when predictions are used to guide conservation or restoration decisions. We used a multi-model approach to predict climate change impacts on big sagebrush (Artemisia tridentata), the dominant plant species on roughly 43 million hectares in the western United States and a key resource for many endemic wildlife species....

Understanding how annual climate variation affects population growth rates across a species’ range may help us anticipate the effects of climate change on species distribution and abundance. We predict that populations in warmer or wetter parts of a species’ range should respond negatively to periods of above average temperature or precipitation, respectively, whereas populations in colder or drier areas should respond positively to periods of above average temperature or precipitation. To test this, we estimated the population sensitivity of a common shrub species, big sagebrush (Artemisia tridentata), to annual climate variation across its range. Our analysis includes 8175 observations of year-to-year change in...

This publication identifies areas where big sagebrush populations are most and least vulnerable to climate change and demonstrates where continued investment in sagebrush conservation and restoration could have the most impact.

On November 4, 2016, Dr. Peter Adler, Utah State University, discussed how sagebrush sensitivity to climate change varies across the region and the strengths and weaknesses of various climate modeling approaches. Healthy big sagebrush habitat is essential for the persistence of many high value conservation species across the western US. To gain confidence in predictions of climate change impacts on existing populations of big sagebrush, a research team from Utah State University compared output from four modeling approaches, each based on very different data and assumptions. These models largely agree that rising temperatures will decrease sagebrush cover and biomass in the warmest portions of the region, but increase...
