WRV works to remove invasive species from the Wissahickon, and replace them with native species. To learn more about invasives and natives, please click on one of the links at left.

We are also compiling as much information about the local flora of the Wissahickon as possible. You can find every plant that has been identified in the Wissahickon Valley Park by following the link at left to our online database, courtesy of the Academy of Natural Sciences in Philadelphia. Please feel free to email [wrv.info@rhd.org] us if you have any questions, if you have spotted a plant that is not on the database, or if you would like to submit a digital photo of a plant.
