The major recommendation from an environmental viewpoint is to preserve the habitat of the plants. This will mean that the exact ranges of each endangered specie will need to be mapped. This information will help in locating reserves that should be established for habitat protection. We should expect to find that many of these endangered species already occur in public lands such as national and state parks, wildlife and game refuges.
