Distribution of Berberis Taxa at Purola Preserve in N. Hays County

In July 2008 the Berberis plants that were the basis of my phenological survey from 2004 through 2007 were plotted as a Google Earth overlay of the Purola Preserve, using my GPS. Each plant was photographed and gps coordinates noted, a total of 113 gps points. (All hybrids are plotted, even though most were not included in my phenological study.)

A Google Maps version of these points is given below. Clicking on any icon will generate a window with a picture of the plant(s) at that point, a short comment and the coordinates of the point. Three types of icons represent the status of the plants:

Berberis trifoliolata (30 plants)
Berberis swaseyi (33 plants)
Hybrids (50 plants)

But Google Maps does not permit sizing or exact placing of icons. For a much better view, download the following kmz file, and open it in the Google Earth application:

Please zoom to the maximum level to obtain a somewhat better separation of the icons representing individual plants. Even so, the result will not be comparable to the source kmz file noted above.
