Restoring Ecosystem Functionality and Biodiversity in Minnesota’s Changing Climate

Presenter: Heather Holm, biologist, pollinator conservationist, and award-winning author

The Zoom presentation is available on the Videos page.

Talk Summary: Four unique biomes converge within Minnesota along a southwest to northeast continuum. Prior to Euro-American settlement, the four contiguous biomes included prairie grassland in southwest and west, tallgrass aspen parkland in the northwest, boreal forest in the northeast, and a mixture of oak savanna, oak woodland, and deciduous forest sandwiched in the middle of these western and eastern biomes. These landscapes have since been radically altered and, with the climate warming, what does the future have in store for Minnesota’s landscape and remaining biome fragments? The presentation will look into the past to understand these biomes at the time of Euro-American settlement, and discuss how Native Americans managed and influenced the composition of the biomes with the regular use of fire. Pivoting to look into the future using projected climate modeling, Heather will address the ecological conditions today, focusing on oak ecosystems and grasslands, then paint a picture of what a functional, biodiverse, and resilient landscape may look like in the future, and what actions are needed to achieve these outcomes.

About the Presenter:  Heather is the author of four books: Pollinators of Native Plants (2014), Bees (2017), Wasps (2021), and Common Native Bees of the Eastern United States (2022). Both Bees and Wasps have won multiple book awards including the American Horticultural Society Book Award (2018 and 2022 respectively). Heather’s expertise includes the interactions between native pollinators and native plants, and the natural history and biology of native bees and predatory wasps. Her work has been featured in the New York Times, Minneapolis Star Tribune, and many local publications. Heather is also an accomplished photographer and her pollinator photos are frequently featured in print and electronic publications.
