FY2013Shrub-dominated ecosystems of the Great Basin are being threatened by disturbances, typically wildfire followed by encroachment of invasive plants (e.g., cheat grass). To mitigate these threats and future changes in the climate to big sagebrush (Artemisia tridentata), restorationists require a knowledge base and tools to inform them of the most appropriate seed sources to plant to greatly enhance the success of restoration under contemporary and future climates. We propose to develop climate-responsive seed transfer zones based on associating plant quantitative traits and ecophysiological data from common gardens to the climate of the seed source.

The sagebrush steppe is a patchwork of species and subspecies occupying distinctenvironmental niches across the intermountain regions of western North America. These ecosystems facedegradation from disturbances and exotic weeds. Using sagebrush seed that is matched to its appropriateniche is a critical component to successful restoration, improving habitat for the threatened greater sage-grouse and other species. The need for restoration is greatest in basin habitats composed of two subspecies:diploid basin big sagebrush (A. tridentatasubsp.tridentata) and tetraploid Wyoming big sagebrush (subsp.wyomingensis). In this study we assess seed weights across five subspecies-cytotype groups of bigsagebrush and examine...
