Title: Plants found only in the Edwards Plateau of Texas area
Answered by: Barbara Medford
The difficulty here was in figuring out what would qualify as the "area." I started with Travis County, and quickly realized that there were very few endemic (found only in one area) plants to Travis County, and that they had small populations and would be difficult to find and even more difficult to get a picture. Finally, I settled on the Edwards Plateau. See this map of the Vegetational Areas of Texas to get a feel for the area we are dealing with. This North American Regional Center of Endemism has a study on the botany of the Edwards Plateau and we were able to find quite a few to research a little further. You have to realize that many of these plants are probably now found in other areas, due to cultivation or transplant, but that is about as close to "only found in this area" as we can get. Please caution your Scouts not to go out looking for these, as some of them are endangered, with very small populations remaining in the wild. They should not be disturbed.
