(minimum altitude 2,000 m) is severely degraded by human activities. Various patches of more or less intact forest remain on the slopes east of the depression, which are connected to the main Andean chain by ridges above 2,500 m. Study sites and methods The study focused on three forests at higher altitudes (generally above 2,400 m) of Ayabaca province, one on Cerro Chacas, a mountain isolated from the main Andean chain (Bosque de Cuyas), and two on a spur on the west slope of the main Andean chain (Aypate and El Toldo; see Fig. 1). Aypate is on a somewhat isolated mountain connected to the main Andean chain by a ridge. For each site the coordinates reflect the general area of the sites.

However, the forest extends from Cerro Chacas, incorporating other cerros and quebradas, so the locally used name Bosque de Cuyas seems more appropriate in describing this location.
