The Nine Mile Run watershed is home to a substantial urban forest that includes all of the trees within the watershed boundaries, from the small sapling in your back yard to the massive trees in Frick Park. The distribution of these trees, is not equal throughout, though. Some streets are completely lacking tree canopy, while others have not only a significant amount of canopy, but a broad range of species as well. These areas enjoy varying benefits from the watershed urban forest. While areas with large trees are likely to see a reduction in stormwater runoff, and urban heat island effect and are also benefiting from improved air quality and property values areas with smaller, or fewer trees are less likely to enjoy these benefits. When we compare these presumed benefits to our social equity map we can begin to better site trees to bridge that social/environmental gap by increasing the benefits in target areas.
This map shows the overlay of the the two studies, the Urban Forest Equity study as well as the NMRWA Environmental Equity Map.
