This page was just begun on 12 January 2016 to hold the geographic distribution maps for the random Asteraceae species we decide for one reason or another to create.

See Geographic Distribution Maps for an introduction to these geographic distribution maps, and maps of all the points for all species in our database. That coverage map, and the map for a given species, allow one to know where we have surveyed and have not found that species.

These maps were made from our incompletely-digitized records, as of 12 January 2016. Click on the maps for slightly-larger versions.

The number of GPS points in our records is given for each species. See Geographic Distribution Maps for a number of things to be kept in mind about these points.

The elevation ranges in our records for the Borrego Desert area are given for each species. If the records show a fairly-continuous distribution in elevation, a single range is given. If the lowest elevation records, and/or the highest elevation records, do not show a fairly-continuous distribution, those outlying records are given in parentheses, so that one knows the elevations at which a given species is commonly seen.
