Service Description:

Water Quality

Nutrients provide the basis for life, but when they occur in excessive amounts, they can threaten water quality for people and wildlife. Sources of excess nutrients include sewage and excess agricultural and landscaping fertilizers from storm water runoff. We can protect water quality for birds and people by working to reduce sources of excess nutrients and ensure that wetlands and streamside vegetation, which act as nutrient filters, are maintained and restored.

Processing

We mapped the current footprint of Nitrogen and Phosphorous loading by identifying 3-km cells with high levels of these nutrients (0.8 or greater on a scale of 0-1).

Most Relevant IUCN - CMP Unified Direct Threat Classification
