Butterflies with Heidi Holman, Wildlife Biologist, & George DeWolf, Baker Ponds Butterfly Count Coordinator
(Rain date August 19)
Heidi Holman is a wildlife diversity biologist with the NH Fish and Game Department. Her primary responsibilities include implementation of recovery efforts for at-risk butterflies and the New England cottontail rabbit with habitat restoration and release of individuals from captive breeding programs. Recently, Heidi launched the NH Butterfly Monitoring Network, a collaborative effort across the state to create awareness of the species in our state and collect current data on their distribution and abundance.

George is an amateur naturalist who struggles to focus on any one corner of the natural world—he’s interested in just about everything. He serves as coordinator of the Baker Ponds Butterfly Count, New Hampshire’s longest-running butterfly survey; is a Plant Conservation Volunteer with the Native Plant Trust; volunteers at Quincy Bog Natural Area, where he guides an annual wildflower walk and leads local school groups on walks around the bog; and is a trail adopter for the Forest Service.
In recent years, his focus has been on raising awareness of butterflies—offering online training in their identification and inspiring others to observe them and support their conservation.

In celebration of our 60th anniversary, we invite you to join us in August for a month-long BioBlitz —a collaborative effort to document the biodiversity across our conserved campus. With two hundred acres of forests, fields, and wetlands to explore, the Science Center’s property depends on many eyes, ears, and curious minds to help uncover and record the plants, animals, fungi, and insects that call this place home. Using the iNaturalist platform, visitors of all ages can help catalog the living organisms that make this landscape thrive.
New to iNaturalist? We are offering short introductory sessions on Mondays and Wednesday at 11:30 a.m.
Take part in our Bioblitz: Walks with an Expert series to learn directly from scientists and naturalists while contributing meaningful community science data that supports biodiversity research and conservation. Don’t miss the Bioblitz Celebration and Wrap-up on September 4 to hear the results. Download the app and be part of the fun!
