Quantifying the status, trends, and demography of Tahoe draba (Draba asterophora), a Lake Tahoe Basin rare alpine plant

The alpine plant, Tahoe draba (Draba asterophora), is among the endemic plant species that occurs only in the Lake Tahoe region. We assess the status, long-term trends, and demographic vulnerabilities of Tahoe draba in the northern and southern Lake Tahoe Basin (LTB). To accomplish this, we: 1) Collate and digitize historic monitoring data of Tahoe draba populations; 2) Reestablish density and demographic monitoring transects of Tahoe draba in both its northern and southern LTB populations and monitor plants for 3 years; 3) Analyze current and historic data to quantify demographic rates, current status, and long-term trends of Tahoe draba in northern and southern populations.
