| 摘要： | We received NPS Challenge Cost Share Funding (PMIS 159489) in FY2010 to pilot a pollinator monitoring project, focused on bees, in Boston Harbor Islands National Recreation Area. Globally, bees have been of conservation concern because both agricultural and natural ecosystems depend on these important pollinators, and accumulating evidence suggests that populations of some species are declining and geographic ranges are shifting in response to changing climates. Native bees are an ideal group to monitor on the Boston Harbor Islands because they are diverse and abundant, easy to sample with a standardized, repeatable protocol, and their taxonomy is relatively well known. Our main objectives were twofold: (1) to develop a robust, repeatable monitoring protocol with statistical power to detect relatively small changes in native bee abundance and diversity over multi-year intervals; and (2) to involve citizen scientists both in the field, sampling bees, and in the lab, sorting and preparing specimens. We set up 16 bee bowl transects on nine islands, and sampled four times during the blooming season. These efforts yielded 3,938 identified bee specimens comprising 104 species, including 23 new species records for the park. Spatial variability for bee abundance across plots was high, and in order to use this index for long-term monitoring, the sampling design may need to be modified. However, we predict that species richness will be an effective measure for detecting trends with the current design. Project participants included 10 community volunteers who contributed 326 hours in the field and lab to sample and process specimens, as well as one dedicated bee intern, and 12 NPS staff and other interns. This project successfully integrated scientific and community involvement goals, and protocols are in place to repeat the sampling for future monitoring. |
