COVID-19 UPDATE: The Harris Center is canceling or postponing all in-person programs and events through May 4. The Harris Center building will also be closed to visitors until May 4. Our trails and grounds remain open.
Citizen Science Programs
Uniting People & Science for Conservation
The Harris Center's citizen science programs train community volunteers to gather ecological data aimed at protecting and restoring wildlife — and wild places — in southwest New Hampshire.
On the first warm rainy nights of spring, thousands of amphibians migrate from woods to wetlands in a natural phenomenon known as “Big Night.” It’s a perilous journey, especially when they must cross busy roads to reach their breeding pools. To reduce the risk of roadkill, we train citizen scientists to serve on Salamander Crossing Brigades at amphibian road crossings throughout the Monadnock Region.
Vernal pools are temporary woodland ponds that serve as important amphibian breeding habitat. Because they’re small and seasonal, they’re especially vulnerable to development. We can protect these sensitive ecosystems, but only if we know where they are! Our Vernal Pool Project volunteers find and record data on vernal pools, with special focus on public and conserved lands.
Common Nighthawks (Chordeiles minor) were once, well, common in New Hampshire – particularly in cities, where they nested on gravel roofs and hunted insects attracted to street lights. Over the past twenty years, however, nesting nighthawks have disappeared from all but a few New Hampshire towns. In partnership with New Hampshire Audubon, the Harris Center coordinates volunteer monitoring of the state-endangered Common Nighthawk in Keene, one of the last places in the Granite State where this acrobatic insectivore still breeds.
In partnership with The Nature Conservancy and Trout Unlimited, our citizen scientists surveyed nearly 1,000 local culverts and bridges to determine where fish movement is most impacted by roads. Now, a team of conservation partners are using these data to prioritize sites for stream restoration.
The Harris Center maintains a series of study plots as part of SPARCnet, a regional research effort aimed at understanding the effects of climate change on woodland salamanders. With the help of students and citizen scientists, we survey the plots for salamanders each spring and fall.
