The Columbia Wetlands Stewardship Society and Living Lakes Canada, a national organization for Source Water Protection, are working together to address this problem by building their own beaver dams.
We mimic the work of real beavers and install beaver dams in some of our wetlands to try to maintain this open water habitat. x27;fall and spring, says Catriona Leven, an ecologist at the Columbia Wetlands Stewardship Society.
She points out that beavers have long since deserted the western part of the bank at the foot of the Purcell Range in British Columbia.
The wetlands of the westernmost province of Canada constitute a vital habitat for many species, but they have been experiencing degradation for several decades due to climate change.

Located on the migratory route of Pacific, one of the four main flyways in North America, the waters of the Columbia River Wetlands provide a haven for more than 160 species of migratory birds.

According to Living Lakes Canada, some areas of the Columbia River wetlands have lost more than 16% of their permanent open water area over the of recent decades.
The low accumulation of snow observed so far during the winter is also a source of ;concern for groups.
It's been warmer and drier for 40 years now, and the trend is accelerating, says Suzanne Bailey, president of Columbia Wetlands Stewardship Partners.
This partnership, which brings together more than 31 groups, communities and agencies, is dedicated to wetland conservation.
We're losing areas of open water, and without them, where do all those migratory birds go when spring arrives?
A quote from Suzanne Bailey, President of Columbia Wetlands Stewardship Partners
It is in order to best conserve water in the higher regions of the Columbia wetlands that the two groups are collaborating on the construction of artificial beaver dams.
The group hopes that replicating the work of this industrious animal in the Columbia River's 26,000 acres of wetlands will help address growing drought.
We let's do things like beavers, adds Catriona Leven. We follow their methods because they know what works.
