Classification des écosystèmes aquatiques de l’Ontario (CEA)
L’objectif de la classification des écosystèmes aquatiques (CEA) est de fournir un cadre spatial universel et uniforme pour les eaux vives de l’Ontario, qui saisit la nature écologique générale des ruisseaux et des rivières.
La classification des écosystèmes aquatiques (CEA) est un outil basé sur la science qui regroupe et classifie les rivières et ruisseaux selon les caractéristiques suivantes :
- attributs physiques, comme la température de l’eau;
- caractéristiques du bassin hydrographique, comme l’aire de drainage en amont.
Le ministère des Richesses naturelles est chargé d’assurer la gestion durable des pêches et des ressources en eau des ~500 000 km de rivières et de ruisseaux de l’Ontario et d’en tirer des avantages économiques.
La classification des écosystèmes aquatiques réduit la complexité de ces vastes réseaux aquatiques à l’aide de méthodes uniformes et quantitatives qui permettent d’obtenir un ensemble de données normalisées qui aident le personnel du MRN à mener à bien les tâches de planification à l’échelle des paysages et d’élaboration des politiques.
