Evaluation of Local Adaptation in Achnatherum hymenoides and Artemisia spp.: Implications for Restoration in a Changing Regional Climate
Lesley DeFalco, Daniel Shyrock, and Todd Esque
Funding will support tissue and seed collections for two Great Basin taxa that are used in restoration and are important components of wildlife habitat (Connelly et al. 2000, 2011) particularly in the southern Great Basin: Indian ricegrass (Achnatherum hymenoides) and sagebrush (A. nova and/or A. tridentata).
We propose to:
- Make collections of leaves (for genetic analysis) and tillers (for common gardens) from 3-5 source populations of ricegrass that will be combined with current Mojave collections (N~20 populations),
- Propagate ricegrass plants from tillers that will be transplanted into 5 gardens during fall 2015
- Collect seeds of sagebrush for propagation and evaluation in 3 Great Basin-Mojave gardens during FY2016.
