FLOW provides tree planting in the Olentangy Watershed, especially in city parks and school grounds. In 2016, FLOW planted 4,888 seedlings and 515 larger trees with the help of volunteers. New trees increase canopy cover and reduces stormwater flow to streams and rivers. This lessens the flashiness of streams and reduces the amount of erosion and sedimentation entering the streams. This improves and maintains habitat for both fish and macroinvertebrates and is essential in providing resilience to handle with climate change and our growing urban heat island impacts in Central Ohio.
FLOW also organizes river and park clean-ups. FLOW targets groups such as Ohio State University students because campus is a high litter area. Some river clean-ups are conducted along the banks of the stream, while others require a canoe or kayak to navigate the river. In 2016 FLOW’s volunteers collected 418 bags of trash not including larger items that were also removed.
