Priority plant list

With removal of invasive species, we need to replant appropriate natives in Washington Grove. The Friends have identified the following trees, shrubs and groundcovers as priorities. They represent: species currently present in the Grove but that are rare or failing to regenerate; species known to have been lost to the Grove since the 1920s; or those which belong to plant communities typical of this oak-hickory community. The Friends have selected species with attention to potential deer predation, to provide erosion control; and to provide for wildlife. Over time climate change, forest dynamism and our experience will inform revisions to these priorities.
