Unlike the other parts of the creek system, this branch does not flow through any deep ravines.


Highland Creek Wetland Complex

At the mouth of the Creek are four wetlands totaling in size. The Stephenson’s Swamp is both a designated Environmental Significant Area and a Provincially Significant Wetland. According to the Toronto and Region Conservation Authority, the type of forest swamp used to be the most common type of wetland on Lake Ontario prior to European settlement but are now rare. It is a breeding area for several uncommon species, including the blue-gray gnatcatcher and the yellow-spotted salamander. There are three other designated Environmental Significant Areas in the Highland Creek watershed: Highland Forest, Hague Park and the Morningside Park Forest.

Threats from development

Due to development in Scarborough, which has substantially increased the amount of water that historically travelled through the river, there are a number of artificial diversions (use of control channels) to decrease

s are possible, increasing its depth. The river travels through culverts under some major streets. In addition, many of the city's storm sewers drain into the river. The valley of Highland Creek contains a number of interconnected parks which have a system of paved bike and walking paths. As a result of these numerous channel modification projects, mostly implemented in the 1960s and 1970s, much of the creek does not follow its natural path. This is in contrast to the nearby Rouge River, which has fewer in-stream barriers and extensive riparian and floodplain vegetation, and where a wider variety of wildlife, including some climax forest species, can be found.


History

Like many creeks and river valleys in Toronto, evidence of First Nations occupation has been found in this area. A 2005 excavation by the Toronto and Region Conservation Authority near the mouth of Highland Creek found evidence of a Late Woodland or Early Archaic site, thought to have been a place of tool manufacture. The Helliwell family, one of the first settlers in the area, accumulated a large number of artifacts from the last 5,000 years. Highland Creek historically formed a natural barrier to transportation in the eastern part of Scarborough, with the single exception of Military Trail, blocking the eastern sections of

line along Kingston Road, which was unable to negotiate the grade into the creek where it met Kingston Road. During the late 1940s and early 1950s, a new town plan developed in the valley between Kingston Road and the eastern crossing of Lawrence Avenue. The primary road remains as the park access road to Colonel Danforth Park, but the remainder, with few exceptions, was washed out during Hurricane Hazel in October 1954.


Communities along the creek

Highland Creek is also the name of a neighbourhood on the east side of the creek at Old Kingston Road. Opposite the former village of Highland Creek is West Hill, named for its position on the tablelands above the valley.
