Monarch Monitoring in the SuperSanctuary & Beyond…

Each summer, Harris Center ecologists work with community volunteers to survey milkweed density and monarch eggs, caterpillars, and butterflies in a Harris Center-conserved milkweed patch in Peterborough. These data are submitted to the Monarch Larva Monitoring Project (MLMP), an international effort to track monarch habitat, distribution, and abundance during the breeding season. In September, we contribute to long-term monarch migration research by tagging monarch butterflies through the Monarch Watch community science program.

New Hampshire Butterfly Monitoring Network

NH Butterfly Monitoring Network logoThe Harris Center is also a proud member of the New Hampshire Butterfly Monitoring Network, coordinated by New Hampshire Fish and Game. Every July, our team of butterfly-loving community scientists conducts an annual SuperSanctuary Butterfly Count, following methods developed by the North American Butterfly Association (NABA). We also contribute observations to the NH Butterfly Monitoring Network iNaturalist project. All butterfly enthusiasts are welcome, with or without prior butterfly experience!
