Wissahickon Trails

The International Monarch Monitoring Blitz invites community scientists from across North America to come together with the shared goal of helping to protect and conserve the beloved and emblematic monarch butterfly. In 2024, over 5,000 volunteers monitored more than 68,000 milkweed stems and reported more than 16,000 monarch sightings in support of trinational efforts to better understand the monarch butterfly’s breeding productivity, range, and timing in North America. Join Senior Naturalist, Kristy Morley at one of the sessions to monitor milkweed plants for monarch eggs and caterpillars as well as adult monarch butterflies. No experience necessary, all training will be

This teacher professional development program offers educators a unique, hands-on opportunity to engage directly with the scientific process of bird banding. Throughout this immersive field experience, teachers develop a comprehensive understanding of bird migration, behavioral ecology, and biological data collection methodologies by working alongside naturalists from Wissahickon Trails. Beyond the fieldwork, the program intentionally bridges the gap between field research and classroom instruction by equipping educators with the pedagogical tools necessary to integrate authentic bird banding datasets into their lesson plans. By bringing these real-world data points into the classroom, teachers can effectively foster genuine science inquiry, promote environmental conservation
