Many zoos are now expected not just to provide entertainment and education, but are entrusted with the survival of certain species through careful breeding programs, often with the hope of reintroducing animals to the wild as suitable habitat becomes available. While we may not have the resources to help ensure the continued existence of Giant Pandas or Bengal Tigers, each of us can participate in the conservation of native plants, and thus the local wildlife that depends on them.

    • REFERENCES Books A wealth of books are available which provide extensive information on native plants, their importance, and how to landscape using them. Some that WindStar’s naturalists have recommended include: • Easy Care Native Plants ,Patricia Taylor • Native Shrubs and Woody Vines of the Southeast and Gardening with Native Wild Flowers, Leonard Foote & Samuel Jones, Jr. • Taylor’s Guide to Natural Gardening • A Sand County Almanac, Aldo Leopold • Noah’s Garden and Planting Noah’s Garden, Sara Stein Internet Sites If you use a search engine and plug in “native plants," you will be directed to many nurseries which carry native plants, either exclusively or in addition to exotic species. Often there are nice descriptions of the plants and tips on what growing conditions they prefer. You will also find a number of state or regional sites which discuss the flora in that locality.
