Discover Nature: The Value of a Rodent

Discover Nature this week and the value of a rodent.

Though some folks scream and climb the highest point possible when they see a rodent,  there isn't a reason to avoid native rodent species according to the Missouri Department of Conservation.

The term "rodent" may raise images of disease-infested vermin living in garbage-strewn alleys. Actually, most of the negative images arise from two unwelcome imports -- the house mouse and the Norway rat. These old-world immigrants are not typical of native rodents, though. 

Rodents make up the largest group of mammals. Besides rats and mice, they include: squirrels, chipmunks, gophers, groundhogs, muskrats, and the largest rodent in North America -- the beaver. Household pets like hamsters, gerbils and guinea pigs are also classified as rodents.

The word "rodent" comes from a Latin term and means "gnawing" -- something that all rodents do. 

Rodents have special front teeth, or incisors. We use our incisors when we eat corn on the cob! But unlike our teeth, a rodent's front teeth never stop growing. So gnawing is not just a habit to a rodent, it's necessary  to keep their teeth worn down.

Rubbish-drawn rats and mice are undesirable, but most rodents are harmless and beneficial. Although they sometimes choose the wrong things to gnaw on. When a squirrel gnaws on your bird-feeder or on your deck, it's not trying to be destructive -- it's practicing good rodent dental care.

Rodents provide a natural length in their environment through seed dispersal, providing food for predators, and other benefits.

Candice Davis is the former host of Discover Nature on KRCU. Her goal is to help people to discover nature and learn to appreciate the many outdoor opportunities Missouri has to offer. Candice knows that people who spend time in the outdoors are generally less stressed, more thankful, healthier and more successful in life. Children who spend time outdoors have better grades and are more physically active. It’s Candice’s goal to inspire Missourians to discover nature in their everyday lives through stories of butterflies, elk, tupelo trees, alligator gar and other marvels of nature on KRCU’s Discover Nature program.
