Abstract
The field work portion of our research on the biogeography of invertebrates and vascular plants has been completed. The geomorphological, bumble bee pollinator and plant community models developed during the first two field seasons worked well when applied to new sites in Dinosaur National Monument (DINO), Canyonlands National Park CANY), Arches National Park (ARCH), and Natural Bridges National Monument (NABR). Our research objectives for the 1993 field season were to: (1) complete the survey of plant and insect communities of hanging gardens in DINO, ARCH, CANY, and NABR; and (2) determine the geographic distribution of endemic species identified and the level of endemism within and among parks; and (3) complete the Halls Creek area survey for hanging gardens in Capitol Reef National Park (CARE).
