Quantitative monitoring of long-petaled lewisia in the Region began in 2004 when plants were located and counted at 3 population sites (Dick’s Lake, Triangle Lake and Azure Lake) in 6 subpopulation sites. A new subpopulation was discovered near Azure Lake in 2006, and near Triangle Lake in 2009, and new populations were discovered near Jack’s Peak in 2011, and Ralston Peak in 2012, bringing the total number of known populations to 5, with 12 subpopulations. All known subpopulations are censused by LTBMU staff every 5 years at a minimum (typically more frequently), and long-term demographic monitoring occurs every 3 -5 years in permanent plots established at 2 populations. An extensive survey was completed for long-petaled lewisia in 1991 and 2 long-term monitoring plots were installed at Region Peak in the Tahoe National Forest and within the LTBMU at Keith’s Dome above Triangle Lake. Plant populations are visited every 3-5 years (more frequently when data suggests the pop. is decreasi
