Volunteers: Thanks for joining us! If you have not adopted a grid cell yet, please do so by following the instructions beneath the map. We encourage you to adopt a cell within one of the purple priority areas. Please note that the light green patches on the map are currently known endangered rusty patched bumble bee zones. Green grid cells that are predominately covered by currently known endangered rusty patched bumble bee zones are not open to adoption by those not covered by a recovery permit from the US Fish and Wildlife Service. If your activities are covered by a USFWS permit and you are interested in adopting one of these cells, please adopt these grids. We will contact you to discuss special instructions.
Volunteers without a permit may adopt a purple grid cell that contains a red patch, but must conduct their surveys outside of the land covered rusty patched bumble bee zones. Collection in these areas requires special care, so volunteers adopting those grid cells must commit to attending a brief training session held annually in early June or review the recording, available on our Online Training page. Please see the Events page for more details about other training sessions.
Where we need your help: Our goal is to conduct surveys in grid cells that were not surveyed in the previous year. These priority regions include biologically unique landscapes or ecoregions that are relatively under surveyed. Surveys in northern Minnesota are particularly relevant for examining populations of the yellow banded bumble bee, a species has experienced severe decline but can still be common in some areas. Surveys in southwestern Minnesota could help document populations of the American bumble bee and the southern plains bumble bee. Many parts of the northwestern part of Minnesota have never been surveyed!
Bright purple: High priority. No recent atlas surveys; not a lot of data in this area.
Gray: Grid cell has been previously adopted, so we already have some data here, but still open for adoption. If you can, please try for a purple cell.
Green: Requires FWS permit to adopt grid
Blue and green blocks: These are scattered across the map, primarily in southeastern MN and require a FWS permit to handle bumble bees.
Dark green: These patches scattered across the map represent public lands that are open for surveying.
