The National Wildlife Federation's Community Wildlife Habitat program is a national recognition program for neighborhoods, towns, cities, and counties that create a community where people, wildlife and plants can all flourish. The program engages homeowners, businesses, schools, universities, places of worship, parks, civic and community organizations and others in creating and certifying wildlife-friendly landscapes on their properties. Each individual certified site provides the four basic elements that all wildlife need: food, water, cover and places to raise young. The program also encourages gardening in an environmentally friendly way, planting native species of plants and replacing lawns with trees, shrubs and other plants. These certified habitats help to create corridors for wildlife to thrive throughout the community.
In 2016, Rockville was recognized by the National Wildlife Federation as the 88th certified Community Wildlife Habitat in the United States.
