Invertebrate Species
Pollinator Monitoring Plan

May 10, 2021 in progress

Project description

Declines of insects are being reported worldwide and includes several pollinator species in California. With reduced abundances and loss of species, there is a possibility that the ecosystem function of pollination is being compromised. The most common pollinators are Hymenoptera (bees and wasps), Coleoptera (beetles), Diptera (flies), and Lepidoptera (butterflies and moths). Overall, about 87 percent of plant species are pollinated by insects. San Diego Association of Governments TransNet Environmental Mitigation Program’s Regional Management and Monitoring 2021-2022 and 2023-2024 workplans include objectives to improve wildlife movement. These objectives are based on the San Diego Management and Monitoring Program’s Management and Monitoring Strategic Plan for Conserved Lands in Western San Diego County (MSP Roadmap; SDMMP and TNC 2017). Objectives for 2022-2026 are to prepare and implement a monitoring plan to survey pollinator communities and assess ecological integrity of pollinator functions in coastal sage scrub, chaparral, forblands and grasslands across the MSP Area. This project will prepare pollinator data in 2021 for analysis in 2022 and development of a pollinator monitoring pilot study plan in 2023 to be implemented in 2024. This plan is being prepared in conjunction with a coastal sage scrub, chaparral, and grassland vegetation monitoring plan. Pollinator sampling locations will be co-located at vegetation sampling plots.
