On September 4, 1979, the wild and beautiful Nahanni National Park in Canada's Northwest Territories became the first site to be named to the Unesco World Heritage List. Over the past few years member countries of Unesco have come to realize that the natural and cultural heritage treasures of the world transcend political boundaries and need international cooperation to assure their preservation for future generations of humanity. Accordingly, the World Heritage Convention has been drawn up to work for protection of natural and cultural sites of world significance. Among the objectives of the Convention are establishment of a World Heritage Committee to oversee preparation of a list of appropriate sites; compilation of a list of endangered world heritage; establishment of a world heritage fund; provision of technical assistance; and worldwide promotion of heritage conservation. Since the designation of Nahanni , two more Canadian parks have joined the WorldHeritage List. These are Kluane National Park in the Yukon, noted for its glacier systems; and Dinosaur Provincial Park in the Badlands of southeastern Alberta, recognized for its unequalled dinosaur remains. World Heritage Sites are marked by erection of a plaque describing the qualities that make the site of world significance. (For further information, see Conservation Canada, Winter 1980.)
