- Ecology of the Oak Ridges Moraine
The
Oak Ridges Moraine lies in SouthernOntario ,Canada . It contains the headwaters of sixty-five rivers and streams. It has a wide diversity ofwoodland s,wetland s, watercourses, kettle lakes, kettle bogs, and significant flora and fauna. It is one of the few remaining continuous green corridors in southern Ontario: it remains thirty percent forested and is one of the last refuges for forest birds in all of southern Ontario.The moraine provides habitat for a wide variety of plant and animal species, over seventy of which are threatened or endangered in Canada, including the
West Virginia White Butterfly ,Jefferson Salamander ,Red-shouldered Hawk , and American Ginseng. The moraine's rare wetlands support plants and insects more typical of northern Ontario. The remnants oftallgrass prairie and oak-pinesavanna in the eastern portion are globally threatened ecosystems.Happy Valley Forests

Sugar Maple in most areas, andRed Maple on its eastern edges. It is a provincial ANSI "Life Science" ecological zone.Provincially-significant ecological areas
A number of provincially-significant ecological areas are located in the Oak Ridges Moraine, among them forty-eight wetlands, and twenty-eight earth and life science Areas of Natural and Scientific Interest (ANSI-ES and ANSI-LS).
The table below lists the ecological zones by municipal jurisdiction; for zones that overlap multiple jurisdictions, the zone is listed in the jurisdiction which contains the greatest portion of that zone. Moreover, some of the zones listed may only have some portion of their complex on the Oak Ridges Moraine; for example, a small southern component of the "Ansnorveldt Wetland Complex" lies on the northern edge of the Oak Ridges Moraine.
