Brought back to lab alive (#318) First rock outcrop 20 traps 2 animals 2/20 P. maniculatus 1 snap P. truei 1 - released Gopher sets - 0/4 Total (other than Gophers) 66 traps 14 animals : 21% success P. maniculatus 9 64.3% P. truei 4 28.5% Eutamias 1 7.1% Why no P. crinitus or P. eremicus? and so few Eutamias in what appears to be optimum habitat? Finished the afternoon with vegetation transects, packed up and came home. No specimens except Eutamias saved. Those Peromyscus killed in snap traps were too putrid. Saw no rabbits (sylvilagus) this trip.
