Forests - Introduction

Forest associations within the CLOCA jurisdiction are typical of the Great Lakes-St. Lawrence Forest Region. Upland forests are generally composed of Sugar Maple, American Beech, Red Oak, Black Cherry, White Ash, Iron Wood, White Pine and White Birch. Common valley associations include Eastern White Cedar, Eastern Hemlock, and Yellow Birch. Species including Poplar, American White Elm, Basswood, Willow, Silver Maple, Black Ash, Green Ash, Eastern Hemlock, Yellow Birch, and Eastern White Cedar are often linked with swamps. Conifer plantations occur sporadically within the watershed; Red Pine, Scots Pine and White Pine are the most common plantation species.

Typically, plantations are found on the Oak Ridges Moraine, where past forest clearing activities left the landscape susceptible to wind erosion.

Forested areas within the CLOCA landscape are often confined to valleylands. Other remnant forests occur in a band across the glacial Lake Iroquois Shoreline where the forest cover was left, as the land was unsuitable for farming, owing to the high water table and seasonal flooding in the area. Another significant band of forest cover occurs across the Oak Ridges Moraine, mixed, deciduous and conifer plantations are abundant across this geological feature.

Forest cover within the 638-km2 CLOCA jurisdiction is maintained at approximately 18%. One percent of that total forest cover is within CLOCA ownership and equates to nearly 800 ha of managed forest.
