Vegetation monitoring in the Harvey Monroe Hall Research Natural Area: 1993 baseline data

This data publication contains tree and plant inventories for 27 transects within 9 vegetation community types in the Harvey Monroe Hall Research Natural Area (HMHRNA), located in the Inyo National Forest in California. Data were collected in the summer of 1993. Also included in this package are photographs of the transect starting points, end points and an overview of each transect.The HMHRNA, adjacent to Yosemite National Park's eastern boundary north of Tioga Pass, contains 3,883 acres of relatively undisturbed sub alpine and alpine habitats, including alpine meadows and sub alpine forest, the target ecosystems for which the region was designated. The object of the present vegetation monitoring effort was to establish baseline data on location, as well as species composition and frequency, of different vegetation communities within the RNA, in order to be able to investigate vegetation changes over time, due to direct human impacts or large-scale perturbations such as climate change.
