As part of a joint wildfire mitigation effort, CPNMD and the City have teamed up to split the $36,000 cost of dispatching a roving goat herd to multiple neighborhoods and open spaces in Castle Pines. Pictured top to bottom: Goats On The Go® Denver South goat herder/owner, Russ McKenna, CPNMD President Chuck Lowen, and City of Castle Pines Mayor Tracy Engerman are on hand as the goat herd moves from one open space area to another near CPNMD’s newly renovated water treatment plant in HOA 1. Well-managed goat herds provide an efficient, environmentally responsible wildfire mitigation alternative to clearcutting, loud equipment, and toxic herbicides. Over time, as the goat hooves work their natural waste byproducts into the soil, they substantially improve the soil’s essential microbiome and water-retention qualities. Dense stands of Gambel Oak are a primary focus of the City/CPNMD wildfire mitigation effort.
