The National Wildlife Foundation has a program through which communities can create, and then receive recognition as, a certified Community Wildlife Habitat.
Here’s how they describe a Community Wildlife Habitat:
A Community Wildlife Habitat is a community that provides habitat for wildlife throughout the community–in individual backyards, on school grounds and in public areas such as parks, community gardens, places of worship and businesses. It is a place where the residents make it a priority to provide habitat for wildlife by providing the four basic elements that all wildlife need: food, water, cover and places to raise young. The community also educates its residents about sustainable gardening practices such as reducing or eliminating chemical fertilizers and pesticides, conserving water, planting native plants, removing invasive plants and composting. It hosts workshops about gardening for wildlife, and holds community events such as stream or trail cleanups to make the community healthier for wildlife and people alike. A Community Wildlife Habitat project creates a place where people, flora and fauna can all flourish.
Participants in the program must earn a certain number of points, depending upon their size; thereafter, there are required post-certification goals.
