For over 30 years, Penns Valley Conservation Association has worked alongside farmers, landowners, agencies, and volunteers to protect and restore the watershed. PVCA has helped ensure that the valley’s natural resources are protected for generations to come. This site, "Plant This...Not That," identifies commonly planted invasive species and the native species we recommend as an alternative. Native trees, shrubs, and herbaceous plants offer optimal food for pollinators and migratory and overwintering bird species, as well as beautifying the landscape!
