Monadnock Region Vernal Pools

Click on any placemarker in our interactive map of vernal pools on public land in the Monadnock Region for photos and data from the 251 documented and 55 potential vernal pools identified by our volunteers on public and conserved land in southwest New Hampshire. Green pins represent documented vernal pools; orange pins represent potential vernal pools that need to be revisited during the amphibian breeding season. This map does not include data for vernal pools on privately owned land, except with explicit landowner permission. Last updated in December 2023.


This map represents the collective work of more than 100 volunteers and interns, including a number of Keene State College and Antioch University New England students, over the course of 17 field seasons. Many potential vernal pools still need to be ground-truthed. To help, contact Brett Amy Thelen.
