LAKE ERIE NORTH SHORE WATERSHED PLAN<br />

be used as an indicator of whether or not the recommendations provided in the<br />

<strong>Watershed</strong> <strong>Plan</strong> have maintained and/or improved the physical and chemical<br />

characteristics of water quality in the watershed.<br />

On-going classification of vegetative communities using standardized protocols<br />

(Ecological Land Classification). These habitat areas are recorded as<br />

Geographic Information System layers and are updated bi-annually to evaluate<br />

changes in community composition, habitat size and fragmentation.<br />

Biological life assessments (qualitative and quantitative) such as<br />

insects/pollinators, fish and birds.<br />

A compilation of the number and location of BMPs implemented in the<br />

watershed. This will also include pollutant loading reduction measurements. This<br />

information will be housed in a restoration database and updated as projects are<br />

completed.<br />

<strong>Watershed</strong> landowners should also be surveyed (at least every 5 years prior to<br />

the <strong>Watershed</strong> <strong>Plan</strong> review) to help watershed planners and the restoration team<br />

identify new watershed issues, and evaluate changes in knowledge and<br />

behaviour.<br />

Land use and land use change in the watershed will also be evaluated. One option of<br />

evaluation methodology is by using the Agricultural Non-Point Source Pollution (AGNPS)<br />

model. AGNPS is a computer model that is used for evaluating the effect of<br />

management decisions impacting a watershed system, such as predicting nonpoint<br />

source pollutant loadings within agricultural watersheds. For example, AGNPS can<br />

simulate the effects of various management practices on pollution in the watershed. The<br />

model can predict where runoff from rain, snowmelt, or irrigation may carry pesticides,<br />

fertilizers, or sediment throughout a watershed.<br />

It is recommended that the AGNPS model be executed for the <strong>Lake</strong> <strong>Erie</strong> <strong>North</strong> <strong>Shore</strong><br />

<strong>Watershed</strong> <strong>Plan</strong> study area to assist the Implementation Committee in identifying „hot<br />

spots‟ in the watershed and therefore priority areas for remediation or restoration. In<br />

addition, the AGNPS model can be used to evaluate the success of restoration<br />

measures in subsequent years after the <strong>Watershed</strong> <strong>Plan</strong> has been implemented by reevaluating<br />

pollutant loadings in the watershed.<br />

The overall objectives of the <strong>Lake</strong> <strong>Erie</strong> <strong>North</strong> <strong>Shore</strong> <strong>Watershed</strong> <strong>Plan</strong> monitoring program<br />

are to:<br />

continually evaluate and amend the watershed plan whenever necessary to<br />

reflect changing environmental, economic, technical, or social trends;<br />

continually assess the overall health and water quality of watercourses;<br />

improve the AGNPS model calibration; and<br />

gauge the success of the restoration action plans in protecting and improving<br />

water quality and aquatic health.<br />
