Beavers played a crucial role in our wetland landscapes from prehistoric times until it was hunted to extinction in the 16th century for its fur, meat and scent glands. (The label on his lab coat, which translates to Dr. While exploring his new territory in 2010, Gallardo was stunned. Katherine Gallagher is a writer and sustainability expert. WebBeavers are known for building dams, canals, and lodges. Small, insignificant streams are transformed into cascading mosaics of dams, pools and wetlands, all providing new homes for all sorts of native wildlife, from dragonflies, fish and frogs to water voles, otters and water birds. The size of these ponds and wetlands can be restricted by the use of flow devices where pipes set the maximum height of the dam, and thus the area of land flooded. The species is difficult to maintain in captivity, so most of the conservation based research pertaining to saiga takes place in the wild. They can obstruct culverts and restore wetlands in places that are not compatible with the existing land-uses and therefore create real, and perceived conflicts.

They impact local habitat, too: By hunting p The industrious creatures have spread to Chile and to the Argentine and Chilean mainlands, leaving dead forests and stagnant ponds in their wake. Beaver dams redirect rivers and replace flowing water with stagnant ponds, altering the kinds of wildlife that can thrive there. Curto explains: Achieving eradication will depend exclusively on sustained political will.
