Long Term Environmental Monitoring

What is Long Term Environmental Monitoring?

Environmental monitoring is essential for properly managing our natural resources. Monitoring provides us with scientifically-based, quantitative information that enables us to make environmentally sound, informed planning decisions and to set appropriate goals for environmental management and rehabilitation.

In 2005, Conservation Halton implemented the Long Term Environmental Monitoring Program (LEMP for short). This program ensures that monitoring is completed in a consistent manner over an extended period of time. It also provides a comprehensive understanding of the structure and function of local ecosystems, which is necessary for assessing the long-term health of the watershed. 

Designed to monitor species, ecosystems, and changes in the watershed over time, the Long Term Environmental Monitoring Program helps ensure that Conservation Halton’s purpose to “protect our communities and conserve our natural environment through planning, education and recreation" is being fulfilled. 

Monitoring results

Conservation Haltons monitoring focuses on different watershed groupings each year with sites being revisited on an annual, biannual or 5-year cycle depending on the parameter monitored.  In 2017, Monitoring was focused on the Grindstone Creek and Sixteen Mile Creek watersheds. Reporting focused on the Grindstone Creek watershed where aquatic results reported on both the biological communities and the physical and chemical attributes throughout the Creek.  Terrestrial reporting in the Grindstone Creek watershed focused on the forest communities of the Waterdown Woods Resource Management Area and the marsh communities located in the Fucciarelli Resource Management Area.

At the end of the five-year cycle, a complete watershed report card is published on the health of the watershed. Click the button below for more.

Conservation Halton Ecological Monitoring Protocol

Conservation Halton’s Ecological Monitoring Protocols document provides guidance on preferred protocols and information required for submission to Conservation Halton, for monitoring projects that are ongoing in the watershed and are typically related to the plan review process.
