I counted Dellandria in some of the sparser appearing squares. The least number in any square was 15. The range was from 15 to about 250. We are trying to find a good method of finding all the invertebrates under Dellandria plants to get a good idea of the biomass of the area. At 1:00pm Ray and I explored a dirt road that heads NE from Chilca. # We took it 20 miles back. The hills around were rocky and barren. The whole valley was a dry river bed, very dry and dusty. The road went by a series of haciendas, separated by several kilometers. 4:00pm. We went back to the study area and Pearson + Ray set out the small Shermans again. I checked my snap traps. One had the trigger depressed, but the rusty spring was still keeping the trap from snapping. I fixed it and reset it. Dellandria tends to grow in rows across the hill. The new Dellandria is lowermost: old dead matted Dellandria new Dellandria - upright.
