Rank Reasons
Viola tomentosa is endemic to California and is known from El Dorado, Nevada, Placer, Plumas, and Sierra counties (CNPS 2001). While V. tomentosa is considered rare (CNPS 2001 and Hickman 1993), it is widely distributed enough and occurs in sufficient numbers that currently the potential of extinction is low (CNPS 2001). V. tomentosa, is however, threatened by road building, vehicles, logging, and proposed resevoir construction in national forests (CNPS 2001). This violet is found in lower montane coniferous forest, subalpine coniferous forest, and upper montane forest on gravelly soil between 1435 and 2000 meters in elevation (CNPS 2001).
Threat Impact Comments
Viola tomentosa is threatened by road building, vehicles, logging, and proposed resevoir building in national forests (CNPS 2001).
