47. No Mow Establishment How wide? Goal 50’ but 15’ will help Establishment Remove turf and invasives Seed with native mix Set clear mowing boundaries Maintenance Monitor and control invasive plants “Mow” once in February Cut no shorter than 6” Little Crum Creek Buffer installed by CRC and Ridley Park Borough Photo courtesy of CRC
