Abstract
WRITING in the second issue of Canadian Nature (Whittemore Publishing Co., Toronto), Mr. Alan F. Coventry deals at length with an interesting experiment in conservation made on 88,000 acres at King Township, near Toronto. A survey of natural resources found the human population to be 4,600, and since 1840 the wild-life has decreased through human interference. The only large mammals left are deer on Holland Marsh; the imported European hare is one of the most abundant, first appearing in 1925, and the area seems to be the northern limit for winter survival of the imported ring-necked pheasant. Depletion of natural water supplies and need for reafforestation are also noted. It is pointed out that the findings of the survey are applicable to a large part of southern Ontario, and similar surveys to the King Township investigation are recommended for other regions, so that the information gained can be used for conservation and for remedies to overcome increasing tendency towards flood and drought dangers. In no more than a century, about 2,500 acres have been abandoned as no longer fit for cultivation.
