There is a great article in the Smithsonian Magazine about South Africa’s Vergenoegd Löw Wine Estate that deploys an army of Indian Runner ducks to eat snails, bugs, and other pests without chemicals. The vineyard is near the ocean and struggles with white dune snails that would decimate the grapes without the ducks. The duck manure also provides natural fertilizer. And to protect the ducks from mongoose and owls the vineyard has a gaggle of geese. Ducks and chickens are a tactic many of us can use to keep our yards healthy!
I pledge to take care of my yard without synthetic pesticides, weedkillers and fertilizers except on rare occasions to resolve an infestation or to improve habitat for native plants and wildlife. I also pledge not to throw pharmaceuticals or chemicals down my drains or toilets.
