Durham Region Coastal Wetland Monitoring Project

The Durham Region Coastal Wetland Monitoring Project is designed as a long-term program assessing the health of 15 wetlands along the north shore of Lake Ontario in Durham Region (see map below).

In order to standardize the collection of biological and physical data among the partner organizations, a Methodology Handbook was developed by Environment Canada and the Central Lake Ontario Conservation Authority and field work began in the spring of 2002.

Both physical features and biological communities are being assessed through this project.

Following two years of field work, the Durham Region Coastal Wetland Monitoring Project: Year 2 Technical Report was prepared by Environment Canada and CLOCA staff. This 266-page document describes the data collected and analyzed from 2002 and 2003 and is designed for a scientific audience. Download a PDF version of this document by clicking on the cover page on the left (PDF - 9.1 MB).

For less technical information about the project and a summary of results by wetland, please download a PDF version of the Durham Region Coastal Wetlands: Baseline Conditions and Study Findings (2002 and 2003) document by clicking on the cover page on the right (PDF - 3.4 MB).

Durham Region Coastal Wetland Monitoring Project - 6 Year Technical Report

Most recently, the Durham Region Coastal Wetland Monitoring Project: 6-Year Technical Report was completed by Environment Canada and CLOCA. This document describes the data collected and analyzed from 2002 to 2007. Due to the length and detail of the technical report, it has been produced in 4 separate modules that can be read independently of one another. You can download the modules in PDF format by clicking on the links below:

Module 1 – Introduction and Assessment Methods (PDF - 827KB),
Module 2 – Geophysical Condition (PDF - 8MB)
Module 3 – Biological Condition, (PDF - 2.6MB)
Module 4 – Wetland Status (PDF - 1.6MB)

What can I expect to see in the future?

It is anticipated that a fact booklet for non-technical audiences providing details of the program and its results from 2002- 2009 will be produced in 2011.
