We will be characterizing relationships between native plants and their associated bee species within the Carpinteria Salt Marsh Reserve. We plan to focus on 5 native and 5 non-native plant species. We would like to take plant clippings once during the study of each species for the UCSB Herbarium at the Cheadle Center for Biodiversity and Ecological Restoration. These plants are to confirm our identifications and they will be vouchered in the herbarium. Bees visiting these plants would be collected, except Bombus crotchii or Bombus californicus due to their status. Bees will be vouchered in the UCSB Invertebrate Zoology Collection also at the Cheadle Center. A proposed plant species list is given at the bottom of this document, which will be used to guide collection decisions in the field. However, sampling will be somewhat opportunistic, as we will only be collecting flowering plants in bloom, so most likely not all proposed plant species will be able to be sampled. Because of the endangered status of both Salt Marsh Bird's-beak and Salt Marsh Goldfields, we will not be collecting plant specimens of these plant species. Emma Gobbell, who will be conducting this study, is able to identify both endangered plant species and endangered/declining bumblebee species. This study will add to the general knowledge base of invertebrate species in the marsh, specifically bees. The findings will be added to the online checklist of CSMR bees found at https://library.big-bee.net/portal/checklists/checklist.php?clid=7&emode=0.
