If habitat is in short supply, programs need to be started to create more habitat and preserve what is left. The importance and success of management programs to protect wildlife cannot be overstated. On pages 206-207, your book lists and describes many successful wildlife programs that have saved species from near extinction. The key to all these efforts is education. Public support is vital to protect not only populations currently in danger, but future populations as well.
