2023 Webinar: Oaks, Fire & Climate Change
Wed, August 30, 2023 @ 6:00 pm EDT - 7:00 pm EDT
AUGUST 30, 2023 — OAKS, FIRE & CLIMATE CHANGE
Natural landscapes in the US and Canada have been drastically altered by human activities such as infrastructure development, logging, overgrazing, introduction of invasive species, and fire suppression. However, prior to Euro-American settlement, highly functional and biodiverse oak and/or pine grassland systems dominated throughout much of the continent. With the current threat of climate change, it is crucial to understand the past and present ecological conditions of these landscapes to inform future restoration efforts.
The presentation will look into the past to understand grassland systems at the time of Euro-American settlement and discuss how Native Americans managed and influenced the composition of these grassland systems with their regular use of fire. Heather will also discuss the impacts of fire as a strong selective pressure on keystone plants and bees. 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.
Presenter Bio
Heather Holm is a biologist, pollinator conservationist, and award-winning author. She passionately informs and educates audiences nationwide, through her writing and many presentations, about the fascinating world of native pollinators and beneficial insects, and the native plant communities that support them.
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.
