Continued raining until 6 p.m. when it let off for about 2 hrs. We set about 30 museum specimens up the road a half mile at the edge of grassland and micro-bamboo. Many lambdas such as horkerry and Retama and young zire. Two-trees go quite a distance up into the bushy-bamboo part, but still grassy in those places. Wild pigs have de-turfed large patches of closely-cropped grassland near the road and obviously are competing with two-trees for tubers or roots. Heard Chacoan on this trail line and maybe what-what. Rain flurries again 7:30 to 8:00, which may have stormy many trails. Counted growth rings on a 3 1/2" diameter piece of zire firewood = 27 yrs. Auntie's dozen snail traps held (Dryzomyx), (Phyllotis riverofus, and 3 also longipalis. May 19 Some wind at stars during night, no rain all day, about 2/3 rds cloudy. A zire stump about 3 1/2" along the road right-of-way at our grid was 25 yrs old.
