Ralph Grundel, PhD
My research focuses on reducing extinction risk in animals and restoration of landscapes.
I lead a team that focuses on improving the scientific basis for conservation of pollinators and savanna landscapes, improving landscape connectivity, reducing extinction risk for threatened and endangered species, and documenting the effects of climate change on species and landscapes, especially in the Great Lakes region and in support of national parks. I work out of the USGS Great Lakes Science Center’s Lake Michigan Ecological Research Station within Indiana Dunes National Park.

Relieving the Sting: Spatial Prioritization for Pollinator Conservation Under a Changing Climate
Project Overview The Rusty Patched Bumble Bee, and other native bees and pollinators, are declining due to climate change, habitat loss, and other stressors like pathogens and pesticide-use. Researchers supported by this Midwest CASC project will study how certain stressors interact to affect the geographic distribution of Rusty Patched Bumble Bees, using mapping techniques and future climate data
Using Pollinator Environmental DNA to Assess the Ecological Resilience of America’s Grasslands
Scientists from six USGS science centers are collaborating with USDA, university, and Tribal partners, and Department of the Interior land managers, to assess the status of pollinator communities and the distribution of species of conservation concern using environmental DNA. These methods will be used to improve assessments of habitat quality and pollinator responses to restoration, including...

Terrestrial Native Species and Habitat Restoration: Kirtland’s Warbler Cowbird Control
By 1971, 69% of Kirtland’s warbler (a rare songbird with a limited breeding range in southern Ontario and the Upper Peninsula of Michigan) nests were parasitized by Brown-headed Cowbirds (a parasitic brood bird native to the Great Plains), resulting in less than one young Kirtland’s warbler produced per nest. Cowbird trapping began in 1972, and parasitism rates were quickly reduced to around 6%...
