Pennsylvania has identified over 250 invasive plants, insects, pathogens, and animals that significantly impact the environment and agricultural production—causing hundreds of millions of dollars in economic losses each year. The Pennsylvania Invasive Species Webinar Series is dedicated to addressing this critical issue. Each session highlights timely topics related to invasive species in Pennsylvania and beyond, including species identification, management strategies, ecological impacts, and key concepts in invasion biology. The series is designed to be accessible to a broad audience. Whether you are a gardener, naturalist, land manager, educator, or simply curious about invasive species, these webinars provide a clear introduction to the issues—no prior knowledge required. By raising awareness and sharing practical information, the series aims to empower communities and spotlight the ongoing efforts of state agencies and partners working to protect Pennsylvania’s landscapes and resources.
