ASSESSING THE RELATIONSHIP BETWEEN WATER QUALITY AND WATERSHED PROTECTION: A CASE STUDY IN QUÉBEC, CANADA
The provisioning of water of adequate quality for various human uses is a critical ecosystem service for which demand is rapidly growing. Upland protection (the percentage of protected area within the associated upstream watershed of a given point), is one of the important factors that can help ensure the provision of water quality. In this study, we explore the relationship between upland protection and water quality to help inform the importance of considering watershed boundaries when creating protected areas to optimize their contribution to water quality provisioning. Focusing on water quality data from the province of Quebec, Canada (n=220), we use Generalized linear models and model selection to assess the role of upland protection and land-use on water quality. Results suggest that freshwater bodies with upland protection provide better water quality than those with none, that watersheds with agricultural or urban land-use do not provide as high quality water, whereas those with wetlands and high quality river banks do. These results demonstrate the relationship between how society manages landscapes and water quality provisioning, emphasizing the importance of strategically designing protected areas to optimize their contribution to providing clean water.
