A booming beaver population is causing trouble in a central Newfoundland town.

About 30 beavers are clogging up Corduroy Brook Trail in Grand Falls-Windsor, and several of their dams and lodges have caused flooding. 

Barry Manuel, executive director of the trail association, said they will soon start trapping the animals to curb the problem and save some trees.

"I've been told that one beaver can chew down 200 trees in a year on its own, so if you do the math on 30 beavers, that's quite a number of trees," said Manuel. 

"There is a healthy population of aspen in the area, so along with the wetlands, it's an ideal habitat for beaver," he added.

Association staff have tried everything to get rid of the nuisance beavers, from ripping out entire dams to ill-fated irrigation systems. They even tried using scarecrows.

Manuel said it's the worst the beavers have ever been at the brook, and as a last resort, they're sending in a licensed beaver trapper.

"We want the beavers, beavers are a good attraction, and we want them to stay around. But if we didn't control the populations, they'd eat themselves out of house and home," he said.

Trapping season starts Oct. 20. 

The association hopes to catch about half of the nuisance beavers and reopen the water-logged trails as quickly as possible.
