Projects and Activities

The SBWA initiates many projects each year often involving partnerships with various community interest groups. These projects aim to improve and protect our watershed as well as educate the public on various environmental issues affecting our area. Past projects of the SBWA include a septic tank survey, bird surveys, tree planting, a coastal stewardship project, archeological study and many ongoing projects such as cattle fencing, stream restoration, educational presentations, beach sweeps and water quality monitoring. Future plans also include activities such as the Community Wetlands Atlas project, the Septic Systems Improvement and Education project and Shellfish Restoration project. Below you will find some of the projects described.

Freshwater Mussels Inventory

Only 25% of the freshwater mussels species found in North America are described as healthy populations. According to The Committee on the Status of Endangered Wildlife in Canada (COSEWIC), freshwater mussels are the most threatened group of invertebrates in Canada. It is thought that approximately 12% of the species are already extinct and that within the remaining species many are classified as either “Endangered” or “Threatened” (Williams et al., 1993). Habitat loss and destruction are thought to be the major causes for the decline of freshwater mussels. Non-native freshwater mussels species invasion can also cause the loss of indigenous species. The Shediac Bay Watershed Association has undertaken a freshwater mussel population inventory in the major rivers found within the watershed: the Shediac River and Scoudouc River.More information ...

Six objectives were addressed during the Freshwater Mussel Inventory Project:
  • Determine the total freshwater mussel species richness and diversity, including rare and endangered species
  • Determine the distribution of freshwater mussel species and describe the habitat in which they are found
  • Determine the relative abundance of each species at each site
  • Determine the abundance and diversity of fish species in the area of study to evaluate the recruitment potential (the life cycle of freshwater mussels depends on specific fish species)
  • Produce a reference document for further consultation
  • Make an inventory of predation evidence on freshwater mussels
Shellfish Restoration
The project was put together to enhance oyster habitat in the bays of Shediac and Cocagne as well as to establish quahaug reproductive sanctuaries in Shediac. As a result of Malpeque disease, native oyster beds are merely 10% of their original biomass. Quahaug populations in the southern Gulf of St. Lawrence have also declined over the past five decades largely due to increasing harvesting pressures. In Cocagne and Shediac Bays, shell material was added to the sea floor (shelling) to create recruitment substrate for oyster spat. It is hoped that oysters will settle on this substrate and create reefs. By creating reef structures, oysters increase biodiversity, provide a viable food source and habitat for many species. Shellfish play an ecologically important role by filtering the water column. They contribute by reducing water turbidity and nutrient pollution effect (for example algal blooms). Recruitment in Cocagne Bay was high and a large number of juvenile oysters are now growing on our restored site. Quahaug reproductive sanctuaries were established in Shediac Bay by planting large quahaugs. By restoring shellfish in these bays, the SBWA is helping to improve water quality for residents and users of the bay. More information ...

Green Boating

Clean water for residents of the Shediac Bay Watershed is important for social, economical, and environmental reasons. At the moment, a large section of Shediac Bay, as is part of the east coast of New Brunswick, is closed to shellfish harvesting because of poor water quality. The increase of anthropogenic activities in coastal regions has contributed to reduce the water quality. As such, with a mandate of improving water quality and promoting ecosystem stability, the Shediac Bay Watershed Association (SBWA) would like to work to promote better navigable practices. Approximately 250 local and visitor boats dock in two marinas located in Shediac Bay. Both marinas are equipped with pump-out stations. Also, both marinas are offering a service of oil disposal threw a local business. The SBWA would like to survey local and visitor boaters and inquire 1) if they are equipped with holding tanks or portable toilets, and 2) the frequency of use of the pump-out stations. For those not equipped with holding tanks, the SBWA would like to assist boaters acquire these by offering information on installers, costs and types available for their boat. The survey will be anonymous to ensure a realistic estimation of the actual situation. Other waste management strategies such as engine maintenance, cleaning methods and products used, hazardous waste spill control and disposal, will be questioned. More information ...
Water Remediation Projects
In order to improve or maintain the water quality within the watershed classified by the Provisional Water Classification, a remediation plan was initiated in the 2003-2004 fiscal year. The SBWA would like to continue and elaborate on this remediation plan by working with the various stakeholders within the watershed. Areas identified in the Provisional Water Classification report of March 2003 require a collaborative effort to remediate and improve the condition and state of our watershed. Causes for such results need to be further investigated in order to properly remediate and improve the water quality of this area. Such investigation involves consulting with stakeholders surrounding this tributary in order to determine the possible point source and non-point sources of pollution and erosion that may be responsible for the lower water quality readings observed in this area. Consequently, farmers and industrial park companies will again be the primary target groups to partner with for developing comprehensive remediation plans. The creation of the water quality management document will assist us by identifying priorities and develop actions in areas were higher risk of pollution have been observed. This profile will be a tool to efficiently manage water quality in the Watershed.

Septic System Improvement and Education

Funded by the New Brunswick Environmental Trust Fund, the Septic System Improvement and Education Project aims to identify and correct failing and problematic septic systems within the Shediac Bay watershed. Problematic and not maintained septic systems can have a very negative affect on the waters leading into Shediac Bay and Northumberland Strait. The project involves studying statistical information such as shoreline sanitary surveys, water quality results, property data information among others in order to identify areas of concern. The project intends to make positive changes by educating homeowners and cottage-owners on their responsibilities with handling septic waste and by offering subsidies to those identified most in need of both financial support and repairs to their system.

Cattle Fencing

Cattle fencing projects are conducted to restrict cattle from directly accessing the watercourses and protect the stream from contamination and bank erosion.





 

Stream Restoration

The restoration of the tributary involved assessing the damage of the area, the construction of erosion control structures and strategically placing “digger logs” in certain locations of stream to redirect the flow of the water and allow sediment build-up from forestry practices to be cleared and the stream to reopen. The intent of the restoration is to restore fish habitat and the stream to its natural state. Sites are selected based on the presence improper buffer zones, poor oxygenation, week riparian zones and low fish habitat and also on the problem areas identified in the Water Classification report.


Water Classification Program
Water quality conditions throughout the watershed will continue to be closely monitored and observed. Water temperature, air temperature and dissolved oxygen readings are monitored and water quality testing is analyzed and studied as well. Under the Clean Water Act, the province has set up a regulation that will help to better protect our rivers and streams. The regulation takes into account the current land use of the area, the existing water conditions as per water quality testing and the public’s input. The tributaries are classed into one of three categories. The SBWA has written the Provisional report associated to the classification. Water sampling for this report was performed by the Scoudouc River Canoe Club under the supervision of the SBWA and the New Brunswick Department of the Environment and Local Government. Sites were chosen according to topography, water flow and drainage area. These locations provided a representative sample of the quality of fresh water throughout the watershed. Regulation: http://www.gnb.ca/0009/0371/0003/0001-e.asp
Public Education
In order to educate and to sensitize the population on environmental issues affecting our watershed, an ongoing education effort on issues such as water conservation and protection raises public awareness with respect to environmental problems and creates an atmosphere of community stewardship. The entire community, therefore, benefits by an increase in improved environmental practices that ultimately result in a better quality of life for all residents. This has been accomplished by delivering presentations to different interests groups and schools, setting up information kiosks at various events, and offering pamphlets and other such publications.
Community Wetlands
Over the years, half due to rapid urbanization of the watershed has reduced coastal wetlands in the Shediac Bay watershed. The importance of maintaining key wetland functions and values, combined with the stresses of rapidly developing watersheds and the dynamic hydrology of the Shediac Bay, make management of coastal wetlands a complex challenge. The New Brunswick Wildlife Trust Fund approved funding to the SBWA to proceed with the Community Wetlands Atlas project. This began in the 2003-2004 fiscal year. The Community Wetlands Atlas will provide information on wetland type, site type, soil type, significance and status as well as a qualitative assessment of stressors affecting the wetlands and biodiversity data for significant coastal wetland-dependent species. Polygons depicting wetland boundaries will be based on data collected from the field and from possible historically collected data archives. The Atlas and GIS (Geographic Information System) database will be used for the following purposes: assess and monitor the status, losses of and changes in coastal wetlands; assist in land-use planning exercises; develop habitat management strategies; target limited resources for conservation and restoration programs; set goals for biodiversity and endangered species recovery plans; support New Brunswick environmental policies and wetland conservation programs; and identify information gaps.

Archaeology Activities
Archaeologist Kevin Leonard carried out a study of the historic sites of the Shediac Bay Watershed, including an Acadian historic site not far from the Shediac River. It is believed that French military officers occupied this site in the 18th century. Dr Leonard presented his research to the schools of the region. His presentation included collected information on his research project, and the results of the previous work done in the region. This was done in order to explain the importance of preserving the environment and to allow us to know the impact of the human presence on the local environment with each passing year.
