Oregon state university wild bee-forest management research: Understanding the influence of stand age and management on pollinator communities in manged conifer forests

Co-P.I. (2018-present)

Funded by USDA Agriculture and Food Research Initiative (AFRI)


Managed conifer forests of the western US cover over 145 million acres of land, but we lack basic knowledge about pollinator populations in this abundant land use. In this study, we are comparing bee communities, bee habitat, and pollination services in managed conifer forests in the Oregon coast range. Using trapping, netting, pollinator exclusion, and managed Osmia nests, we hope to better understand the extent to which managed forests provide habitat for insect visitors, as well as the impact that management decisions have on pollinators and pollination.  


Oregon state university wild bee-forest management research: Understanding the impacts of wildfire on native bee communities


Funded by the FWHMF program, Oregon State University; Bureau of Land Management; Mealey/Boise Cascade/Boone and Crockett/Noble Endowment Fund from the College of Forestry, Oregon State University


Investigating how natural and anthropogenic disturbances influence bee populations in managed forest landscapes. We are using standard sampling methods to compare native bee abundance and diversity among burn severity/salvage logging  in a post-wildfire mixed-conifer forest. Additionally, comparing bee health, reproductive output, and pollination services among treatment types.

University of Idaho and CATIE NSF-IGERT: Evaluating the impacts of Payments for Environmental Services on social-ecological systems


Funded by NSF-IGERT, USAID Borlaug Foundation, ICRAF, and the University of Idaho


Worked in an interdisciplinary team to address the impact of conservation strategies on ecosystem services in Costa Rica. Specifically, asked: 1) How do native bee populations differ among common human-dominated land uses in the Nicoya Peninsula? 2) How has policy-driven land use change  impacted beekeepers in the Nicoya Peninsula? and 3) What ecosystem service trade-offs exist for stakeholders? 

Used standard sampling methods to compare native bee abundance and diversity among silvopasture, coffee agroforestry, and teak plantations in the Peninsula. Applied a mixed-methods approach to assess local ecological knowledge related to the impact of recent land use changes on beekeeping.
