Sierra Nevada Flora

Relatively immobile and often highly visible, plants are typically the first organisms people notice in a landscape. Plant distributions are strongly tied to environmental factors and can be very useful when describing ecosystems and life zones.

There is an incredible diversity of trees, shrubs, grasses, forbs, and vines, with more than 1,450 native and 275 non-native plant species in Yosemite National Park and 1,200 species in Sequoia Kings Canyon National Parks. Not only that, but new species are still being discovered. For instance, one group of researchers noticed something peculiar when they examined old records of orchid species in Yosemite. There was a species listed that was typically found only in the southern Rockies. Because Yosemite is so far from the Rockies, they suspected it might actually be a different species. Using the past records for guidance, the researchers searched wet meadows south of Yosemite Valley for the mysterious orchid. They eventually found it, determined that it was actually a new species of orchid, and named it the Yosemite bog orchid (Platanthera yosemitensis) in 2007.
