Beavers could wind up replacing artificial dams being decommissioned on Vancouver Island | 24CA News

Members of a Canadian conservation group are engaged on a mission to improve biodiversity and wholesome wetlands in British Columbia with the assistance of beavers. Ducks Unlimited Canada is mapping areas within the province the place beavers can substitute synthetic dams as soon as they have been decommissioned. 

“Beavers are a keystone species,” mentioned Jen Rogers, a grasp’s pupil at Simon Fraser University working with Ducks Unlimited Canada. “They’re considered ecosystem engineers.”

The staff is at present assessing areas on Vancouver Island the place beavers had been traditionally over-trapped to make room for engineered dams.

Many of these synthetic buildings at the moment are a long time outdated and due to get replaced. The staff hopes to revive the beaver inhabitants, not solely to exchange the dams however to offer the added worth of restoring organic range to the panorama.

Roger Dunlop, a biologist and the supervisor of lands and pure assets for the Mowachaht/Muchalaht First Nation, says bringing the beavers again would have a optimistic domino impact on different elements of the ecosystem.

He has been monitoring Gold River water ranges because the Fifties and is worried in regards to the more and more low ranges. He blames the change on deforestation. 

“We’ve replaced [old-growth forests] with young, rapidly growing super tree plantations that require much more water,” mentioned Dunlop. The water loss has, in flip, induced a decline in freshwater species, and as hotter months strategy, the danger of drought will increase.

He says that reintroducing beavers can “rehydrate the landscape,” giving it a break from overuse. Beaver ponds assist surrounding land take up water, permitting it to withstand droughts and floods.

“If you think about it, forestry in B.C. is really overgrazing, just at a larger scale,” mentioned Dunlop. “The blades of grass are just trees, right?”

Dunlop says his experience as a biologist informs his work, as does his identification as a member of the Mowachaht/Muchalaht First Nation. He says First Nations communities involving themselves in biodiversity work is essential. 

“They’re exercising their right to take better management control of this particular landscape that’s really been over-harvested,” he mentioned. 

The mission is at present within the evaluation part, utilizing knowledge fashions to finest decide which areas their efforts needs to be concentrated in. Rather a lot goes into beaver reintroduction, so they’re additionally engaged on plans for co-ordinating with land homeowners, trapping and monitoring the animals, and retaining observe of water ranges. 

“That takes time,” mentioned Dunlop. “And that is definitely what’s planned for this landscape.”
