In response to this growing crisis, the Scott River Watershed Council (part of the Klamath River system) has been working with U.S. Rancher’s Best FriendĪs the planet warms and Earth’s climate changes, water shortages - especially in the state of California - are increasing. While the trees and plants themselves provide shade needed to keep water cool and fish populations thriving. Deep root systems from these plants maintain bank structure and combat erosion. In turn, positively influencing the diversity and survival of many other species of animals and insects. Beaver ponds increase the surface area of water several hundred times this increased water supply increases vegetation growth by increasing the amount of groundwater for use by riparian plants and wetland areas. Riparian = refers to the areas of land located along the banks of rivers or streams (image source: Colorado Riparian Association).īeavers shape and maintain healthy riparian habitat ( see illustration at right). 2004), and his research also supports that beaver ponds benefit the river ecosystem as a whole. Michael Pollack of the National Oceanographic and Atmospheric Administration (NOAA) has studied the relationship between beavers and juvenile salmon for over a decade ( Pollack et al. The readily available food and protective environment in beaver ponds lead to increased salmon growth and survival. Studies conducted in streams along the Oregon coast suggest that the winter survival of juvenile Coho salmon, which can be swept downstream by fast flowing winter streams, depends on adequate slow-water habitat. By creating ponds, beaver dams enhance over-wintering habitat that can shelter young salmon from swift, high water flow events. When beavers build a dam, they create a pond behind it. Beaver Benefits: Why you should give a dam Relationship to Healthy Rivers, Salmon and Other Animals Inside their lodge, beavers have a safe place to sleep, raise their offspring, stay warm in winter, and hide from predators. A beaver lodge is built out of twigs, sticks, rocks, and mud, and has an underwater entrance. They also use grass, rocks, and mud.ĭo beavers live in a beaver dam? Nope! Beavers build dams so that they have a safe pond where they can build their beaver lodge (den). What do beavers use to build their dams? Beavers build their dams out of trees and branches that they cut using their strong front teeth. they live up to 24 years of age in the wild.they slap the water with their broad tail to alert other beavers to danger.while slow on land, they are good swimmers and can stay under water for as long as 15 minutes.their incisors contain so much iron that the enamel is bright orange.beaver incisors (front teeth) never stop growing, withstanding the constant wear of chewing and cutting down trees.they are the second-largest rodent in the world after the capybara.they are a primarily nocturnal, semi-aquatic rodent.Take action today in support of banning beaver hunting and trapping. Unfortunately, historic trapping efforts to create a “fur desert” in Oregon resulted in dramatic declines of the species and trapping continues to this day.Ĭascadia Wildlands is currently attempting to prohibit commercial and recreational trapping of beavers on federal lands through a petitioning effort to Oregon’s Fish and Wildlife Commission. Prior to European arrival in North America, Oregon’s streams and rivers may have harbored an estimated one million North American beaver. A North American beaver ( Castor canadensis) builds a dam (photo by Chase Dekker).īeavers critically influence the ecosystems of the Pacific Northwest and play a fundamental role in creating and maintaining a diversity of flora and fauna associated with Oregon’s streams, rivers, and wetlands. Beavers are known as “ecosystem engineers”, or “nature’s architects”, because their dam-building work has such a huge effect on the habitats around them.
