Apparent climate-mediated loss and fragmentation of core habitat of the American pika in the Northern Sierra Nevada, California, USA

Fig 1

Sites surveyed for American pikas in the north Lake Tahoe area, California, USA.

The Pluto triangle is bounded by Lake Tahoe, highway 267, and by the Truckee River, adjacent to highway 89. Current sign of American pika was found both east and west of Pluto triangle; nearly all sites within the Pluto triangle yielded old fecal pellets (see also S1 Table). Map boundaries represent our boundaries for the north Lake Tahoe area.
