Determining Effective Mitigation Techniques for Vernal Pool Wetlands: Effect ofHost-Specific Pollinators on Vernal Pool Plants

摘要

In this study, the authors compare the diversity and quality of pollinator guildsof showy vernal pool plants in natural and created vernal pools, especially in Madera and Solano counties. The authors' surveys emphasize pollen host-specific andrenid bees on the assumption they are the most effective pollinators of the showy vernal pool plants. The authors find the oligolectic (pollen specific) bees in most natural relatively undisturbed vernal pool habitats, at least in the central portions of the ranges of the host plants. When created pools are constructed in areas where the bee fauna exists, they readily forage on their host plants growing in created pools. The authors review the literature, published and unpublished on the vernal pool habitat and analyze it in relation to frequency through time, by all categories, and by faunal categories to determine the information available on the pollination process.
