Les zones humides sont des milieux de faible énergie très fragiles où il y a peu de mélange par turbulence. Ils sont donc particulièrement vulnérables à un stress causé par une exposition à des hydrocarbures.

Wetlands are highly sensitive, low-energy environments with little turbulent mixing and, as such, are particularly vulnerable to stress from exposure to contaminant hydrocarbons. Their restoration is problematic due to the fragile nature of the soil, making it difficult to remove contaminants and enhance recovery without negative impacts, since human cleanup activities may do more physical damage than the contamination itself. A less intrusive methodology of restoration is needed that initiates, accelerates and enhances contaminant removal, with the least disruption to habitat.

Menaces prioritaires : les barrages situés sur les bassins hydrographiques qui drainent dans les Grands Lacs ou le fleuve Saint-Laurent (y compris la rivière des Outaouais), le bassin hydrographique de la rivière Winnipeg/English River et le barrage Moses Saunders sur le fleuve Saint-Laurent; la récolte continue de l'esturgeon jaune dans les lacs intérieurs et les affluents des Grands Lacs - le bassin-versant du haut Saint-Laurent (DU8) et le bassin hydrographique de la rivière English/Winnipeg (DU5); la détérioration des vestiges des zones humides côtières du bassin hydrographique des Grands Lacs/du haut Saint-Laurent

Priority threats: dams situated on watersheds draining into the Great Lakes or St. Lawrence River (including the Ottawa River), Winnipeg River/English River Watershed and the Moses Saunders Dam on the St. Lawrence River; the continued harvest of Lake Sturgeon in inland lakes and tributaries of the Great Lakes - Upper St. Lawrence Drainage Basin (DU8) and English/Winnipeg River Watershed (DU5); harmful alteration of the remnant coastal wetlands of the Great Lakes/Upper St. Lawrence drainage basin

La phytoremédiation, technologie de restauration utilisée dans les milieux terrestres, fait actuellement l'objet d'une évaluation pour déterminer sa faisabilité dans les zones humides. L'écosystème aquatique contient des microbes de dégradation des hydrocarbures.

The feasibility of phytoremediation, a contaminated site remediation technology used in terrestrial environments, is being evaluated for use in wetlands. Hydrocarbon-degrading microbes can be found in the aquatic ecosystem. In wetlands, the most important environmental factors that affect microbial activity and limit oil degradation are nutrient supply and oxygen level. Phytoremediation attempts to harness the potential capacity of wetland plants to remove contaminants from the sediments by direct uptake, aeration of the soil to overcome the oxygen deficit, and/or by producing of stimulatory substances that enhance the microbial rates of biodegradation. Phytoremediation serves the dual purpose of remediation and direct restoration, because the affected plant is the same as the plant replacing it. This project will be the first comprehensive, simultaneous field evaluation of plant revegetation, bioremediation, and natural recovery for the restoration of acutely stressed wetlands.

Le méné camus peut généralement être trouvé dans des fonds sableux ou boueux dans des cours d'eau ou des lacs clairs et stagnants avec végétation. On les trouve dans des étangs abrités, des zones humides, des canaux stagnants et des baies protégées près de grandes étendues d'eau.

The Pugnose Shiner is usually found over sand and mud in slow-moving, clear, vegetated streams and lakes. They are found in sheltered ponds, wetlands, stagnant channels and protected bays adjacent to larger waterbodies. Spawning is thought to occur in late spring to early summer, and takes place in shallow, heavily vegetated waters. They do not guard their eggs, but rather distribute them widely over the aquatic plants and substrates.

Les examens récents de la santé des océans ont révélé une grave diminution des stocks de poissons, la perturbation et la destruction des habitats et une disparition importante des zones humides. D'autres tendances permettent de discerner l'appauvrissement de la qualité de l'eau ainsi que la contamination par les eaux usées ou les produits chimiques, qui ont des impacts environnementaux, sociaux et économiques importants.

The challenge that now faces the intergovernmental community is how to best and more broadly apply the lessons learned at the local and national level. As the global commons, oceans demand cooperation, compliance and commitment. In turn, these essential elements of engagement depend on a greater effort towards capacity building and technology transfer. Participants felt that regional organization represented the most promising and effective level for intergovernmental cooperation and further that the priority action for cooperation and collaboration should be ocean reporting. Reporting is the basic tool to determine progress towards a healthy ocean environment and achieving sustainable development.
