Established in 2013 and expanded in 2015, Raven’s Nest covers nearly 5,000 acres (almost 7.5 square miles). It is located near SPLT’s Heartland Ranch. It includes rolling shortgrass prairie, seasonal creeks and gullies, a several mile perennial stretch of Rule Creek, and gorgeous Dakota sandstone outcroppings. The property provides homes for a variety of herptiles, birds, mammals, invertebrates, and native plants. There are prairie dog populations that attract coyotes, swift foxes, ferruginous hawks, burrowing owls, and many other creatures. The streams sustain plains leopard frogs, tiger salamanders, dragonflies, shorebirds, and other water-dwellers. A variety of lizards, toads, skinks, and snakes, and the western ornate box turtle use the rock outcroppings and other habitats throughout the preserve. The preserve was named after the Chihuahuan ravens who have multiple nests on the property. The Charlotte Adelman and Bernard L. Schwartz Nature Preserve is located within Raven’s Nest’s borders.
