Those who study the beaver call it "nature's finest wetland engineer" (DEC.NY.GOV, "What is Beaver). They are known to impact the waterways that they inhabit in both positive and negative ways. Colonization of waterways provides a unique habitat for furbearer and waterflow species. However, animals that thrive in cooler water, such as reptiles and some fish species, are often forced out of the environment that beavers inhabit, since beaver dams and lodges raise the temperature of the water several degrees.
