■'Little is presented- that is neyr or original, Rather the book
attempts to strip dov'/n the comiplexit^^ of contributions in the field
of conservation to some of the more essential elements .Three concepts
are considorcd to form the basis of the conservation movement t (l) That
soil,y.rator, forest and wildlife conservation are orily parts of one in-
separable program: (2) that wildlife must have an onxrLrorarient suited to
its needs if it is to survive; and (3) that e.ny use that is made of any
living resource m.ust be limited to not m.ore than the annual increase
if the essential seed stock is to be continually available. Tliese three
concepts are the basis of presert ^vildlife and forest conservation
Drogrrm-S,and indirectly of all others.''
