520 | 3 |a"Concern ahout the ecological effects of the altered water regime of the Peace-Athabasca Delta, following completion of the W.A.C. Bennett Dam on the Peace River, led the Canadian Wildlife Service in 1968 to initiate an ecological study. Its objectives are to evaluate the short- and long-term effects of the altered water regime on the ecosystem and to evaluate the environmental parameters which have to be considered in designing measures which would return the delta to a desirable state. This report is a preliminary account of our study of plant succession on exposed silt surfaces"--Abstract. |
