Introduction to
Field Guide To San Diego County
Hikes In San Diego County

Note three important caveats:

San Diego County has perhaps the richest diversity of habitats in the U.S., making it a hiker's paradise. Desert, mountains, sea shore, bays, rivers - we have it all. As a result, we enjoy one of the richest plant communities in the world. We have ~1,800 native plants, more native species than any other county in the contiguous U.S. Unfortunately, we also have more endangered and threatened species than any other county in the contiguous U.S. (Nature Conservancy, May/June 2000, p. 15.)

These pages are a guide to some of the natural richness of San Diego County. This url ( contains two major related sites: Field Guide to San Diego County and Hikes in San Diego County.

Field Guide to San Diego County Website

This is a field guide to many aspects of San Diego County. This site will contain webpages that include, among other pages:

Hikes in San Diego County Website

This is a hiking guide to San Diego County. The site will include:

All information on the web related to a given trail (conditions, web links, view plots, places, etc.) will be collected on a page devoted to a given trail.

See also a more complete introduction for this site.

Both Websites

Both sites are far from complete, even after they are transferred from their old homes, but will gradually become more complete after several years.

Both sites share the following files. All are found in the About This Site area of the main page for each site, except for the search page which is found at the top of the main pages:

Both sites have no connection with any company or organization, and result from the personal work of the author, as well as the volunteer input from readers credited either on the page with their input or on the acknowledgements page for each site. The referenced links are also mostly the result of volunteer effort by many different webauthors, although a few referenced pages come from commercial efforts. No endorsement of any kind is implied by the existence of a link from these pages, other than our belief that there is some useful information contained within those links.

It is a misconception held by some people that webauthors somehow get a fee for every reader who accesses a webpage. This is true only for some commercial sites supported by advertising. In fact, in most cases, webauthors pay money to put their pages online and make it available to the public. Fortunately, the amount of money for a site like this is small, $275 per year for this site. In comparison, since the page charges for many major scientific journals are ~$100 per printed page, my SGM site alone would cost ~$20,000, making the dollar costs of a website essentially negligible!
