This project aims to quantify avian habitat structure and composition along an established avian point-count transect in the central Mayacamas Mountains outside Healdsburg, CA. The surveys were conducted from 8 July through 10 July, 2014, on Pine Flat Road in the central Mayacamas Mountains in Sonoma County, part of which passes through the All Hands Ecology (ACR) Modini/Mayacamas Preserves (Figure 1). This study, along with recent efforts by the Sonoma County Vegetation Mapping Project (sonomavegmap.org) and avian point-count data collected by ACR, will be used to assess avian habitat values in the central Mayacamas Mountains region.
