These videos are documents from two design courses taught by Bill Mollison at the Fossil Rim Wildlife Center in Glen Rose Texas in 1994 and 1995. They are a definitive selection from our original 16 part series. These tapes bear many viewings and will benefit anyone who wants to learn how to help regenerate the earth - from back yard to bio-region. Teachers of permaculture have found these tapes to be a valuable coaching tool - edited to one hour.
