Plans for this 220 acre site in Hugo, MN, included the creation of residential and commercial buildings.
However, the land owner also wanted to increase
habitat for the Blanding’s turtle (Emydoidea blandingii),
a State Threatened species in Minnesota. Several turtle sightings on or near this site had been recorded in the
Natural Heritage Program’s databases, so the likelihood of turtle usage was high. Nonetheless, an assessment of
the planned future land use’s effect on this species was needed.

SER helped the site owners balance site development with threatened species
habitat creation.
SER staff visited the site to make an initial assessment of site quality prior to construction.
Then, a thorough literature review of the Blanding’s turtle’s life cycle, habitat, and diet
requirements was performed. Important details on turtle habitat usage were summarized in a report
that was included in an environmental assessment worksheet (EAW) for this site and that was sent
to the Minnesota Department of Natural Resources (DNR) for review. Using
GIS, SER plotted out
areas that met the habitat requirements (e.g., soil types and wetland types) necessary for
supporting these turtles.
Habitat requirements necessary for this species’ survival were studied. These requirements were
compared to site conditions that would be present after land alteration. SER discussed the site’s
ability to support turtle populations, what areas would be best left unaltered as habitat, and what
precautions would be necessary to make the site suitable for Blanding’s turtle survival and success.
The study was well received by the DNR and the other reviewers, and habitat creation subsequently commenced.
