HCA Receives $1.5 Million Donation to Build Eramosa Karst Conservation Area

The Eramosa Karst is the Hamilton Conservation Authority's newest conservation area.  It is located in the southwestern section of the Stoney Creek area of Hamilton.  It extends from Highland Road to south of Rymal Road, and from Upper Mount Albion Road to Second Road West.

This area is not yet open to the general public.  The HCA will improve access to the area with parking lots, trails and interpretive panels in time for their 50th anniversary in 2008.  A fundraising campaign is already in the works and was kicked off with a $25,000 donation from Multi-Area Developments. 

The Eramosa Karst area was transferred to the Hamilton Conservation Authority on October 23, 2006.  Click here for more information about the official transfer.

Karsts are geological formations including underground drainage, caves and passages caused by dissolving rock, found in limestone formations like the Niagara Escarpment. The Ministry of Natural Resources designated the Eramosa Karst lands as an Area of Natural and Scientific Interest in 2003, because it is believed to have the largest number of unique karst features in any single area in the province.  Several of its karst features are provincially significant.  These include: soil pipes, a high concentration of suffosion dolines and sinking streams, overflow sinks, dry valleys and a 335 metre-long cave (the tenth longest in all of Ontario).  There is also a natural dolomitic limestone bridge at the entrance of one of the sinkholes.

The diversity of geological features and its central location in the Greater Golden Horseshoe, makes the Eramosa Karst one of the best sites in Ontario for education and research opportunities. Protecting the Eramosa Karst’s unique network of features will ensure that scientists, students and naturalists can continue to enjoy this natural resource.  Because it has great potential for education purposes as a result of its features and hydrology, HCA is exploring the possibilities of creating an environmental education centre on the property.

Eramosa Karst Master Plan

The $1.5 million donation came from the Heritage Green Community Trust.  The trust was established in May 1997 to provide support in the form of grants to community, educational or charitable organizations of upper Stoney Creek. The Heritage Green Trust successfully distributes grants to qualifying recipients or organizations who clearly provide demonstrable benefits to residents in the City of Stoney Creek residing south of the Niagara Escarpment and within three (3) kilometers of the perimeter of the Newalta Stoney Creek Landfill Site.

The Nature Counts Hamilton Natural Areas Inventory of 2003 found that the Eramosa Karst natural area is made up of meadow, thicket, woodland and forest remnant communities.  It is located in the Davis Creek watershed.  The forest area is made up of sugar maple, ironwood, hawthorn, gray dogwood, white ash, pin cherry, black cherry, American beech, red oak, butternut and chagbark hickory and a variety of plant species.  A total of 129 species of plants were documented at this site, 13 species of butterfly, 2 species of herpetofauna, 42 species of breeding birds and 6 species of mammals. 

The Eramosa Karst plays a major role in the Hamilton East-end Open Space Replacement Strategy, which seeks to secure some 210 acres of land for new parklands and trail systems to link the karst lands to the Mount Albion and Felker’s Falls conservation areas, expand the latter, and address a number of related natural heritage issues. The strategy was developed in March 2004, by a committee representing the conservation authority, the City of Hamilton and the Hamilton Chamber of Commerce, with input from the mayor’s office and local MPPs.

Take a video tour of the karst features.  Marcus Buck, Hamilton karst expert and co-author of the report that helped turn the karst property into a provincial Area of Natural and Scientific Interest, leads us on a video exploration of the karst geological features that will be interpreted when the property is developed into Hamilton’s newest conservation area.  (Video production courtesy of  Van Valkenburg Communications).  These are Windows Media Viewer files.
