LAKE ERIE NORTH SHORE

LAKE ERIE NORTH SHORE WATERSHED PLAN Table 15: Wainfleet Marsh Subwatershed Restoration Strategy Restoration Opportunities Recommended Restoration Strategies Riparian Wetland Upland and Ecological Linkages 1 most of the watercourses flow through wetland and wooded areas therefore receiving cover from these natural areas; however portions of the headwaters commence in agricultural areas with little to no buffer therefore priority should be placed on establishing riparian habitat in these areas in the southern portion of the study area there are roadside ditches and portions of watercourse that have little to no riparian cover before outletting into Lake Erie, therefore measures to establish and enhance buffers should be considered to reduce sediment and contaminant loads from adjacent land use (roads and agricultural fields) before outletting to Lake Erie riparian buffers will help to reduce sediment and to maintain and enhance the integrity of water quality and fish habitat before outletting to Lake Erie, as well as create corridors that will connect the fragmented natural areas providing cover for wildlife create/enhance wetlands in areas where the wetness index and soil drainage permit; priority should be given to areas adjacent to existing wetlands(e.g., very high suitability for wetland creation/enhancement in northeastern portion of subwatershed): see map very high suitability to create an ecological corridor linking to wooded area in adjacent subwatershed protect existing wetlands (e.g., create a buffer of trees and shrubs between the wetland agricultural activities) high suitability exists for creating a Critical Function Zone surrounding Wainfleet Bog PSW Complex. This will provide for a variety of critical functions for wetland-associated fauna (e.g. nesting habitat) as well as increase interior size resulting in the natural areas‟ ability to support a larger diversity of flora and fauna. potential is present for creating ecological linkages between natural areas facilitating in the movement of flora and fauna between natural areas and adjacent subwatershed All restoration measures should where possible, benefit Species at Risk and provincially rare species Carolinian and native species should be used for all projects 166

LAKE ERIE NORTH SHORE WATERSHED PLAN Project Opportunities NPCA Lake Erie North Shore Geomorphic Assessment Study (NPCA 2009b Naturalizing Drains and Drain Best Management Practices Promote Good Shoreline Stewardship Integrated Roadside Vegetation Management (IRVM) Program Ecological Linkages between Natural Areas Riparian Buffer Education Program Wetlands are Worth It Program Recommended Action for Public and Private Lands 1. Neff Road (WMHeadwaters): This section of the watercourse has been channelized and lacks any depositional features along the stream bed which indicate little flow diversity within the channel. Dense instream vegetation was noted in some areas during a site visit in 2008. Bank instability is present in the form of fallen vegetation and exposed roots along the watercourse. Channel widening seems to be the dominant process occurring due to the presence of leaning trees on either side of the channel, as well as trees and shrubs within the watercourse. Debris jams were also identified along this field site. Small tributaries and/or possibly gullies/rills exist along the watercourse. Measurements taken at channel cross sections would indicate that the watercourse at this field site has moderate entrenchment which results in flood waters having limited to no access to the floodplain. Therefore, the energy within the flow is contained in the channel. Long term monitoring of the debris jams should be completed to ensure they do not get larger and divert the flow. Projects to prevent and limit further development of rills adjacent to the watercourse should be implemented. Some examples include grassed waterways, chute spillways, tile drainage outlets, and proper tillage and cropping practices (OMAFRA, 1997a, and OMAFRA, 1997b). In addition to having an impact on aquatic and riparian habitat, drain maintenance has the potential to become quite costly through repeated maintenance activities. Naturalizing drains can potentially lengthen the time between maintenance events by reducing the amount of sediment entering and remaining in the drain. Best Management Practices for drain maintenance should be developed in consultation with, but not limited to, the following agencies; OMAFRA, DFO, MNR, Conservation Ontario, OFA, DSAO, CFFO, and the agricultural community to reduce ecological impacts to aquatic systems and to prevent sediment from returning to the drain. Any future maintenance of this watercourse should be done in accordance with Best Management Practices for drains. To review examples of current BMP mitigation measures, refer to Appendix I. Work with partnering stakeholders to promote shoreline that have been maintained naturally or restored to find a balance between natural processes and shoreline protection measures. Niagara Region and municipalities should work together to expand Niagara Region‟s IRVM Program. IRVM integrates the use of native vegetation with appropriate management techniques to produce a cost-effective, environmentally sound management alternative for roadside weed and erosion control while providing numerous ecological benefits (e.g. buffer strips). Focus of program expansion should be directed to main roads and roads in areas with a high shallow intrinsic susceptibility. Opportunity potential is present for creating ecological linkages between natural areas creating larger contiguous natural features. Such areas have the potential to enhance movement of flora and fauna between natural areas as well as provide habitat and ecological diversity for a wide range of species. Many landowners keep their properties manicured or plant crops to the edge of the creek. The NPCA‟s program aimed at educating landowners about the benefits of buffer zones along watercourses should be extensively promoted. In addition, landowners should be made aware of and encouraged to participate in the Conservation Authority‟s Water Quality Improvement Program. This program provides grants to a maximum of 75% of the cost of a project with caps between $2,000 and $10,000. Wetlands provide important water quality and ecological functions in a watershed by augmenting low flow, acting as natural filtration systems and helping to reduce flooding by acting like giant sponges and absorbing excess water. The Wetlands are Worth It Program through NPCA‟s Water Quality Improvement Program aims to assist landowners that are interested in restoring, protecting, rehabilitating and creating wetland habitat on their property 167
