The Horse | What Do Healthy Horses and Healthy Fish Have in Common?: "What do healthy horses and healthy fish have in common? More than you think. Conservation Authorities across Ontario typically develop big picture aquatic resource management plans for local watersheds that identify what they and private landowners alike need to do to improve the health of local land and water resources.
A fisheries biologist often points directly to the equine landscape as a positive contributor to healthy watersheds and fish communities. Most equine establishments sustain many acres of well-managed pasture. When pasture is grazed on a proper rotation, frost-seeded in early spring to increase plant production, and small depressions or wet areas are drained using French drains, the horse and the fish in nearby streams maintain better health."
Wow that's great news for horses, trails and watersheds!
