HAMMOND RIVER RESTORATION| RESTAURATION DE LA RIVIÈRE HAMMOND
Over 5000 willow and dogwood stakes were planted along the Hammond River through this project. This project, located approximately 1 kilometer upstream of the Hammond River Conservation Centre, reclaimed 3 kilometers of shoreline thanks to funding from the Recreational Fisheries Conservation Partnerships Program.
During the fall of 2017, HRAA staff planted stakes along banks adjacent to 5 well known pools (Steele’s, Crowley’s, Len’s, Island, and Deep Hole) in the lower main-stem of the Hammond River. Willow stakes sourced from an area upstream of French Village Bridge were planted, as they are more tolerant of ice scour. These stakes are a great for establishing vegetation in the area. If these stakes are ripped out of the banks by ice scour they can re-establish themselves downstream. It is because of this evolutionary adaption that we can use cuttings (stakes) to establish full trees/shrubs.
In 1998, the HRAA completed a similar project by planting willows immediately downstream of this site and now 20 years later they are full sized trees! Hopefully in 20 years, the stakes we planted in 2017 will look just as good!
Plus de 5 000 pieux de bois de saule et de cornouiller ont été plantés le long de la rivière Hammond dans le cadre de ce projet. Ce projet, situé à environ 1 kilomètre en amont du Centre de conservation de la rivière Hammond, a permis de récupérer 3 kilomètres de littoral grâce au financement du Programme de partenariats pour la conservation des pêches récréatives. À l'automne 2017, le personnel de HRAA a planté des piquets le long des berges adjacentes à cinq bassins bien connus (Steele, Crowley, Len, Island et Deep Hole) dans la partie inférieure de la rivière Hammond. Des piquets de saule provenant d'une région en amont du pont du village français ont été plantés, car ils tolèrent mieux l'érosion par la glace. Ces enjeux sont parfaits pour établir la végétation dans la région. Si ces enjeux sont arrachés des berges par l'érosion par la glace, ils peuvent se rétablir en aval. C'est à cause de cette adaptation évolutive que nous pouvons utiliser des boutures pour établir des arbres / arbustes entiers. En 1998, l'HRAA a complété un projet similaire en plantant des saules immédiatement en aval de ce site et maintenant, 20 ans plus tard, ce sont des arbres de taille normale! Espérons que dans 20 ans, les enjeux que nous avons plantés en 2017 seront tout aussi bons!
COMMUNITIES IN ACTION FOR A BETTER BRADLEY BROOK
COMMUNAUTÉES EN ACTION POUR UN MEILLEUR BRADLEY BROOK
Evan and Rhyse working hard to stabilize the bank.
This picture was taken in 2017, showing the result of the 1998 restoration efforts of the HRAA
Slumping that occurs as a result of little to no trees to stabilize the banks. Here we can see how roots are stabilizing the bank, but without deep taproots penetrating deeper, bank collapse occurs.
This year the HRAA will complete a 2 phase project to improve conditions in Bradley Brook. Our project Communities in Action for a Better Bradley Brook is sponsored by EcoAction through Environment and Climate Change Canada. The first phase will restore 0.4 hectares of riparian buffer from fallow pasture at the confluence of Bradley Brook with the Hammond River. Riparian trees along the brook will function to stabilize banks, reduce sedimentation, improve water filtration, and reduce overall stream temperatures. This fall the HRAA will then partner with local schools, the Town of Rothesay and Quispamsis to host a 4 km stream clean up along Bradley Brook. Bradley Brook currently has the highest density of garbage of the region and this work will require many hands! Stay tuned for volunteer stream clean up days.
Cette année, l'HRAA completeras un projet en 2 phases pour améliorer les conditions dans Bradley Brook. Notre projet, Communautées en action pour un Bradley Brook amélioré, est parrainé par le programme de financement communautaire EcoAction par Environnement et Changement climatique Canada. La première phase permettra de restaurer 0,4 hectare de tampon riverain des pâturages en jachère au confluent de Bradley Brook avec la rivière Hammond. Les arbres riverains le long du ruisseau fonctionneront pour stabiliser les banques, réduire la sédimentation, améliorer la filtration de l'eau et réduire les températures globales des cours d'eau. Cet automne, l'HRAA sera ensuite partenaire des écoles locales, de la ville de Rothesay et de Quispamsis pour accueillir un ruisseau de 4 km le long de Bradley Brook. Bradley Brook a actuellement la plus grande densité de déchets de la région et ce travail nécessitera de nombreuses mains! Restez à l'écoute des jours de nettoyage des bénévoles.
The HRAA asked our community to share areas of concern for future projects, and now we are delivering! Crowley's pool, located off the Stock Farm Road, has been a historically popular local fishing hole. It was actually anglers at this very pool, in 1975, that first initiated talks of forming an angling group for the Hammond River. Despite our community's love for this fishing pool, there has been an evident decline in fish abundance, and environmental quality here. Erosion has become quite severe in this area, the banks are barren, and up to 7 m high in some areas.
In 2016, the HRAA received funding from the Habitat Stewardship Program Prevention Stream to conduct a hydrological site assessment of the area. This site assessment was completed by Dillon Consulting and resulted in a deeper understanding of the mechanisms driving erosion and infilling in the area. Restoration designs for the pool's bank were completed however, no funding has been secured to complete the work. The HRAA has approached the town of Quispamsis for partnership on funding this work. Once a grant is secured, multiple sources of funding will be needed to complete the project. The restoration work is designed to restore this valuable fish habitat and prevent further infilling. It is our goal to find a mutually acceptable way to solve issues of erosion and the potential loss of the Stock Farm Road at Crowley's Pool.
PALMER BROOK ENHANCEMENT INITIATIVE
The Palmer Brook Enhancement Initiative was created to reduce levels of E. coli and improve water quality in Palmer Brook. Water quality sampling over the past two decades has indicated E. coli levels are rising in Palmer Brook, and exceeding Health Canada’s acceptable limit (400 MPN/ 100 mL) for recreational use.
Rising levels of E. coli are associated with high water temperatures and high levels of sedimentation. Water bodies adjacent to grassland and fallow pasture, such as Palmer Brook, are particularly susceptible to sedimentation and high water temperatures. Trees around brooks provide shade and help to reduce the amount of sedimentation that enters the water. In 2016, to improve water quality, the HRAA planted 3,600 native trees on both sides of Palmer Brook. This enhancement initiative will help to restore fallow pasture to its natural vegetated state over time.
While the HRAA has taken this step to combat rising levels of E. coli, the benefits will not be immediately measurable, and further initiatives will be needed for a permanent solution.
Water quality testing by the HRAA in the 1990’s indicated that E. coli was originating from a non-point source in Palmer Brook. The HRAA will need to conduct further investigations to identify whether this is a systematic problem with utilities infrastructure, a result of farming in the area or a combination of both. The HRAA plans work with the town of Quispamsis, to develop new projects to address the issue of E. coli in Palmer Brook.
E. coli has been rising in Palmer Brook. E. coli levels have been measured above the acceptable limit for recreation health and aquatic life (dashed line).
RESTORING ATLANTIC SALMON HABITAT IN GERMAINE BROOK
Germaine Brook is a tributary to the Hammond River and contains historically important spawning grounds for Atlantic salmon. In recent years, poorly vegetated banks, beaver dams, erosion upstream, and the increased frequency of rainfall events has caused changes to Germaine Brook. These changes include channel instability, heavily eroding banks and a diversion of the brook from its original flow pattern. These changes have coincided with a significant decline in annual redd (salmon nest) and juvenile (fry and parr) counts in the brook. Erosion in Germaine Brook has led to accumulated fluvial deposits and the formation of bars on the stream banks. These bars and a beaver dam now block the stream from reverting to its original channel and braiding pattern.
The objectives of this project are to restore the natural channel of Germaine Brook by removing barriers that prevent the stream from accessing its floodplain and to stabilize 2500 square meters of steeply undercut banks through a combination of techniques such as slope armoring, stream diversion, and vegetation. By restoring channel stability, reducing sedimentation events, and removing barriers to fish passage in Germaine Brook, this project will improve salmon spawning/ juvenile habitat and enhance populations of recreational fish species. This project is funded through the Recreational Fisheries Conservation Partnerships Program. The assessment for this project is completed, and funding for the work will be obtained through a future grant.
