Areas searched without locating species:
On September 16th, 2001 Yuma Point and the Eastern Edge of Eremita Mesa were searched. It was a difficult survey and very little good habitat was found. Good habitat was visible on the shelf below the edge, but this area was impossible to survey; binoculars were used to search for plants but no plants were seen.
