It’s near the end of fall in the watershed, a good time to reflect on cycles of life and how we fit in to the larger ecosystem. There is much to be thankful for. Almost a century ago, a few visionary people advocated for parks like the US Arboretum and the Kennilworth Aquatic Gardens, both on the banks of the Anacostia, to make some space for birds, trees and people where they could take a break from the engines of industry. Over the years these places have only improved as the trees and wetlands cleaned the air and water and people worked to protect and restore the river. We have a long way to go, and reminders of our ongoing challenges linger. But, for the ability to take a walk beneath trees in a watershed alive with countless forms of biological life, that is something to be thankful for.
