Room to Roam

A greater sage-grouse can really bust a move! Because of their large home ranges, they depend on connected sagelands for survival.

American black bears have large home ranges and often come into conflict with people, since they roam considerably.

The elusive mountain goat is hard to spot, but they are capable of long distance movement and often meet barriers like roads and other development.

Who doesn’t love a lynx?! This little guy may look cuddly, but his parents are super strong with giant paws that help them hunt in deep snow. They roam among spruce and subalpine forests and are threatened at the state and federal level.

The only way to make a normal squirrel cuter is to add giant eyes and gliding wings: Ta da! Northern flying squirrels need dense tree canopies to survive. Fewer big stands of trees mean fewer flying squirrels.

Western burrowing owls will soon benefit from a habitat connectivity assessment of the Columbia Plateau. These little beauties are on the decline mostly because of fragmented sageland habitat.

Some elk populations in Washington migrate from mountains to low valleys and cover great distances throughout the year.

This map shows the best linkage zones for elk. Bright green shows the areas where elk populations are high, and the yellow areas are the best places to keep connected so elk can move from place to place.

Brad McRae is a spacial ecologist for Washington, with a focus on habitat connectivity and climate change. His mapping software has been used around the world.
