The ecology of the Sierra Nevada, located in the U.S. states of California and Nevada, is diverse and complex. The combination of climate , topography , moisture , and soils influences the distribution of ecological communities across an elevation gradient from 500 to 14,500 feet (200 to 4,400 m).
Annuals plus woody shrubs constitute only about 6% of the number of Sierra Nevada alpine floral species. [1] Sierra gentian (Gentianopsis holopetala), in the gentian family (Gentianaceae), is an erect or sprawling annual or perennial, growing in wet meadows from 6,000 to 13,000 feet (1,800 to 4,000 m) elevation.
