Plant Species of the San Jacinto Mountains

On 2 November 2008, we have begun putting pictures of plant species of the San Jacinto Mountains online, as a prelude to pages that will give information about the distribution and characteristics of each plant species.

On 11 July 2010, we have begun putting maps of species distributions online, which includes georeferencing vouchers from Riverside County.

On 14 July 2011, we have begun putting online a list of all the species observed to be in bloom above 6500 feet, along with plots showing how the bloom has changed with time.

On 30 July 2017, we have begun putting maps of species distributions online from our surveys of Round, Tamarack and Long Valleys.

On 10 October 2018, we have begun putting The Entire Plant Checklist For Our Higher-Elevation Surveys.

See also Species Diversity from the spot surveys we have done.
