No reported data for this Indicator

Number of subpopulation sites within each of the four main population sites of Tahoe draba where plant counts decreased, increased, were stable, or were unknown between 2004 and 2013. Data Source: U.S. Forest Service - LTBMU. The observed increases in population are likely due to more intensive search rather than an actual increase.

General

Program Tahoe Draba (Draba asterophora va. asterphora) Monitoring

Approach

U.S. Forest Service monitoring of Tahoe draba began in 2004 when plants were located and counted at 22 subpopulation sites (Engelhardt and Gross 2013). An additional 3 sites were added in a limited survey in 2005. All sites were re-surveyed in 2009 and 9 new sites were added. In 2013 six sites were revisited and one new site was discovered, and in 2014 14 sites were revisited. All known subpopulations are censused by LTBMU staff every 5 years at a minimum. A comprehensive long-term monitoring program for Tahoe draba was initiated in 2009 when plots were installed at seven subpopulation sites within three LTBMU populations (Engelhardt and Gross 2011a). Monitoring plots were established at three subpopulations within two populations (Relay Peak and Mt. Rose Ski Area) on the Humboldt-Toiyabe National Forest in 2011. Monitoring occurred two years after plot establishment to collect baseline data, and will occur every 3 to 5 years until the species is no longer considered sensitive.
