Along with removing invasive species, we work to replant appropriate natives in Washington Grove. The Friends have identified the following trees, shrubs and groundcover plants as priorities. They represent species that, though present in the Grove, are rare or failing to regenerate, species known to have been lost to the Grove since the 1920s, and species that are typical of this oak-hickory community. The Friends have selected species with special attention to potential deer predation, erosion within the Grove, and the habitat needs of local wildlife. Over time climate change, forest dynamism, and our collective experience will inform revisions to these priorities.
