Beaver kits are born with the ability to swim and normally stay close to their parents as they are very vulnerable to predators when young. The most frequently cited negative impacts were impeded fish movement because of dams; siltation of spawning gravels (particularly for salmonids); and low oxygen levels in ponds. Recent history has shown four mass mortality events in saiga populations accredited to various diseases, of which saiga are especially susceptible. The objectives of the project are to use beavers to restore an area of nationally important wet grassland and to understand the effects that this once-native species will have on this environment. Yet while it may not rival the ecological bounty of a tropical rainforest, the taiga still teems with fascinating animals whose tenacity reflects their ancestors' adaptations to this beautifully harsh habitat. Beavers are often referred to as 'ecosystem engineers'.
