Superheroes - The BeaverChristie Hill, CNC Naturalist Coordinator

If you have frequented the Chattahoochee Nature Center at any point in the last two decades you have probably visited our resident beaver. He is a �ne example of an American Beaver, the largest rodent in North America, and a very well-cared-for one! Many of you have observed him aging into his 20th year, often napping by the fence, sometimes his face not too far from his food bowl. You might think he is a lazy fellow. Beavers are typically busy, energetic builders who create habitats for many other species, and have several heroic characteristics. The beaver is known as a keystone species because of the bene�t he provides to other species. Beavers require a protected place in a river or pond in which to construct a home and will transform entire areas to meet their needs. Their occupation of building dams ensures that their homes (lodges) will be surrounded by water to keep out

predators, and, in turn, provides habitat for aquatic organisms, and nesting grounds and food for migrating birds and many others. See this tireless beaver constructing a dam and click on videos.

Our resident beaver was imprinted as an infant, which caused him to be non-releasable. Back in 1995 an apartment complex manager decided to rid their canal of some pesky beavers (probably because they were taking down trees and rearranging the area). What the manager did not realize is that beavers live in family units called colonies, and that there were not only parents, but babies, called kits, and older siblings, living in the lodge in their pond. (The younger siblings stay with their parents for up to 2 years, helping with infant care, food collection, and dam building). Two kits were rescued and brought by the trapper to CNC. They needed a mother to nurse them, and at the time we took in lots of di�erent species. Caring for the young beavers was di�cult due to round-the-clock care and feeding with bottled formula (the other beaver passed away in June 2005). Today the beaver is a healthy senior, and his diet consists of fruits and vegetables, privet, willow, box elder and a nutritional supplement called Rodent Block. While possibly less active as a captive beaver, you should catch a glimpse of him swimming!
