Papa Leon tree, 150+ ft., Depto. Leonia, Peru July 11 We put out stakes for a Calhoun line on adjacent slopes to the study area. This area has many prints, both of mice or foxes, as well as birds. We put out 20 stakes, 20 yds apart in a more or less straight line across 4 faces of the slopes area 1 area 2 area 3 area 2 has the most Tillandsia. In area 4 the Tillandsia is sparser and the ground sandy. This afternoon we will set 3 traps at each station. This afternoon I took 50 snaptraps and set 3 within 6 ft. of the first 10 and 2 within 6 ft. of the last 10. Pearson & Ray set traps at the places that didn't have traps last night. They took point samples at 1/2 the stake on the grid by pointing a long stick due E and dropping a line down & seeing what it hit. The area is apparently covered by 8% by live Tillandsia + 25% by dead Tillandsia.
