“The loss of foundational but fire-intolerant perennials such as sagebrush due to increases in fire size and frequency in semi-arid regions has motivated efforts to restore them, often with mixed or even no success. Seeds of sagebrush Artemisia tridentata and related species must be moved considerable distances from seed source to planting sites, but such transfers have not been guided by an understanding of local climate adaptation. Initial seedling establishment and its response to weather are a key demographic bottleneck that likely varies among subspecies and populations of sagebrush.We assessed differences in survival, growth and physiological responses of sagebrush seedlings to weather among eleven seed sources...

FY2016Review the existing literature, summarizing what is known about the scale and prevalence of local adaptation in the Great Basin and review current practices for determining seed transfer zones, describing benefits and limitations of different approaches. Through these two reviews, we will identify gaps in knowledge and opportunities for addressing these gaps, and determine best-practices for the construction of high quality seed transfer guidelines in a rapid and efficient manner. We propose to bring together a wide group of partners to achieve these goals, with two working group meetings proposed for this project. Deliverables include two peer-reviewed publications (existing knowledge, recommendation of best...
FY2016Information on climate adaptation of native plants used in restoration is needed to help guide seed transfer from collection sites to restoration areas across the Great Basin. This project evaluates variation among populations planted together in common gardens of sagebrushes or bluebunch wheatgrass to achieve the goal.The need for seeds for sagebrush ecosystem restoration and rehabilitation projects has led to the transfer of seed across climate zones and hundreds of miles. Development and application of climate-based seed zones are needed to improve seeding success and return-on-investment. USGS, in collaboration with USFS, has accumulated considerable data on climate responses of key native (and cultivar)...
