How do beavers affect biodiversity?

When beavers open the forest canopy by damming streams and cutting down trees they create new ecological niches and ecotone habitats where various species thrive. These ecotone and mosaic habitats, are necessary for many declining species such as turtles, bats, grouse, and salmon.

How do beavers help biodiversity?

They increase biodiversity

The influence of beavers and their activity is far reaching. … Beaver activity can increase plant diversity by as much as 33%. As trees are removed and land is flooded, other plant species emerge in its place. These plants provide food and cover for new species.

By gnawing down trees and building dams, beavers open up the woodland around them, allowing pioneering, light-hungry plants to grow. Beaver dams reduce waterflow of rivers and streams and flood the local area, creating the basic requirements for complex wetland habitats to form.

Beavers help maintain woodland ecosystems by thinning out older trees and allowing young saplings to grow. Converting these trees into timber for dams radically alters woodland meadows and streams, changing them into wetland habitats. Invasive species are often ecosystem engineers.

How do keystone species affect biodiversity?

What Effect Do Keystones Have on an Ecosystem? Keystone species maintain the local biodiversity of an ecosystem, influencing the abundance and type of other species in a habitat. They are nearly always a critical component of the local food web.
