Document Summary

Must lay its eggs on a lupine plant (if the caterpillars are removed from it, they die) Only survives in the prairie patches and must find prairie patches, otherwise they do not reproduce. Butterflies today now have difficulty finding these patches, many are going extinct as the smaller prairie patches cannot sustain a population. The kind of modeling that is informing lots of conservation biologists today. Works with pikas, working in a mining ghost town. Pikas live in piles of fairly large rocks, with crevices to live in (tailing piles) Andy realized that pikas lived in tailing piles of the mining caves. Had a northern network, a middle network, and a southern network. Recorded at five year intervals, what percentage of the network had pikas in them. At north, pikas were doing well (provided reservoirs of pikas in certain locations to keep occupancy up in less sustainable locations when they dispersed)
