Riparian Wetland Upland and Ecological Linkages<br />

1. headwaters receive cover from<br />

wetland therefore priority should<br />

be placed on establishing and<br />

enhancing riparian habitat south<br />

of the Gord Harry Conservation<br />

Trail.<br />

riparian buffers will help to<br />

reduce sediment and cool the<br />

water to enhance water quality<br />

and fish habitat as well create<br />

corridors that will connect<br />

fragmented natural areas<br />

providing cover for wildlife<br />

protect existing wetlands (e.g.,<br />

create a buffer of trees and shrubs<br />

between the wetlands and the<br />

agricultural activities)<br />

enhance wetlands in areas where<br />

the wetness index and soil<br />

drainage permit; priority should be<br />

given to areas adjacent to existing<br />

wetlands(e.g. very high restoration<br />

suitability exists between Moulton<br />

Wetland West PSW complexes<br />

and north section of unevaluated<br />

wetland west of watercourse)<br />

restoration suitability mapping<br />

indicates very high suitability exists<br />

for creating a Critical Function Zone<br />

(CFZ) between Moulton Wetland<br />

West PSW complexes and the<br />

northern edge of the unevaluated<br />

wetland by means of infilling. This<br />

will provide for a variety of critical<br />

functions for wetland-associated<br />

fauna (e.g. nesting habitat) as well<br />

as increase interior size which would<br />

support a larger diversity of flora and<br />

fauna<br />

the main branch south of the<br />

Gord Harry Conservation Trail is<br />

managed as a municipal drain<br />

therefore establishment of<br />

riparian corridors(e.g. deep<br />

rooted grasses & shrubs) should<br />

consider future maintenance<br />

activities (refer to engineers<br />

report and drainage BMP<br />

practice recommendations )<br />

All restoration measures should, where possible, benefit Species at Risk and provincially rare species<br />

Carolinian and native species should be used for all projects<br />

NPCA <strong>Lake</strong> <strong>Erie</strong> <strong>North</strong><br />

<strong>Shore</strong> Geomorphic<br />

Assessment Study (NPCA<br />

2009b)<br />

Recommended Action for Public and Private Lands<br />

1. <strong>Lake</strong>shore Road (HvDMa): This section of watercourse is managed as a municipal drain; Hoover Creek<br />

Drain. It has been channelized and lacks any depositional features along the stream bed which indicate little flow<br />

diversity within the channel. Bank instability is present in the form of bare soil extending up the steep bank, and<br />

possibly slumping. Relatively deep unconsolidated sediment is deposited along the channel bed. Few to no<br />

pools exist along the bed but there is stagnant water present throughout the field site. The plant arrowhead, as<br />

well as aquatic vegetation in the form of a vine was identified along the bed of the channel throughout the field<br />

site. The presence of algae was also noted during a site visit in 2008. The riparian buffer along this reach is<br />

poor along the left bank and therefore will influence bank stability. A number of small tributaries and possibly<br />

rills/gullies exist along the watercourse. Measurements taken at channel cross sections would indicate that the<br />

watercourse at this field site has moderate to minor entrenchment which results in flood waters having limited to<br />

no access to the floodplain. Therefore, the energy within the flow is contained in the channel.<br />

Recommendations for this site include not grading the channel banks too steep during the dredging process so<br />
