Climate Change: Special Status Species

Prostrate buckwheat (Eriogonum prociduum)

The proposed project aims to study the reason for population decline in several SSS plant communities.  Significant populations of Prostrate buckwheat (Eriogonum prociduum), Crosby’s buckwheat (Eriogonum crosbyae), and Grimy mousetail (Ivesia rhypara) in the Lakeview District appear to be threatened by local extinction.  District botanists have asked whether climate change may be the cause, and if so, is it affecting the survival of all northern Great Basin endemics?  Vegetation in arid and semi-arid environments such as that of the Lakeview District is regarded to be highly sensitive to climate change.  The goal of this project is to evaluate three areas with seriously declining populations.  If the decline can be attributed to causes other than climate change, then site-specific management recommendations will be implemented.  If not, implications for the effect of climate change on the populations would be assessed and a protocol developed to mitigate the expected consequences.
