By blocking river flow, a beaver’s dam can create ponds or deeper channels of water. Many fish, like Colorado’s Greenback Cutthroat Trout, thrive in the cooler, deeper water created by beaver dams. Slower water flow also provides habitats for aquatic insects (like the caddisfly!), as well as safe spaces for creatures like frogs and turtles to have their babies
Scientists have shown that humans benefit from beavers too! According to NPR, “beaver dams improve water quality, trap and store carbon — and in the aggregate could be a significant way of storing groundwater in dry climates.”
Many species (including humans!) rely on beaver-created habitats to survive and thrive; in fact, nearly half of our endangered species depend either partly or entirely on the influence of beavers on their wetland ecosystem. But one of our favorite things about beavers? We have them right here along the South Platte!
