 Extensive urban growth and urban sprawl over the last century has had a significant impact on habitat that birds and other wildlife once called home.Homeowners with yards and gardens have a unique opportunity to curtail this loss of habitat by creating their own backyard wildlife garden, a wildlife sanctuary.Naturescaping takes some of its principles from the US Environmental Protection Agency's (EPA) "GreenScaping" or "Beneficial Landscaping" programs - which strive to reduce water, energy, and chemical usage.
