Called the “koepa” by the Northern Paiute people, the bighorn sheep is an icon of the mountain West; yet complex disease issues have stalled its complete recovery. Mark discusses the history of bighorn conservation, its life history, management, and how sheep conservationists are trying to solve pressing challenges to sheep recovery. – from the Northwest Nature Mattersepisode page
Recent episodes have featured subject matter experts from state and federal agencies, academia, journalism, and environmental advocacy sectors for long-format conversations about conservation, natural history, and wildlife protection issues across the Pacific Northwest.
Episode 4, released last month, discussed the marbled murrelet – an Endangered Species Act -listed species, like the spotted owl, requires old growth forest for nesting habitat.

The busy, busy beaver is our February Forest Feature.
Beavers, or Castor canadensis, are sometimes called the “engineers of the wild.” They are probably best known for the elaborate dams they construct across streams, flooding surrounding wetlands.
A beaver dam creates a pond that provides habitat for the beavers, and for many other aquatic creatures. Deer and other animals may forage for grass and shrubs that grow in small meadows beavers have created by harvesting wood to build with.
The dams are built from wood, mud, and rocks. Beavers cut down small trees by chewing through them. They may even dig canals to float those trees back to their pond!
The beaver is the largest rodent that is native to North America. A typical adult beaver is more than 3 feet in length, if you include their broad, paddle-like tail, and weighs more than 40 pounds!
You might be surprised to learn beavers don’t live inside beaver dams. A beaver’s home is called a “lodge” and is typically a large mound, also made from branches and mud, located upstream from a dam.
Lodges can have multiple entrances, which lead to an above-water den inside. They even have “skylights” – small holes near the top that lets in fresh air.
Beavers live in colonies of up to a dozen beavers, and a colony may have several lodges!
During the winter, beavers take a break from all their busy building. In places where it gets very cold, beavers will store food for winter at bottom of their pond, or swim out under the ice to harvest underwater plants.
After a few years, when beavers have eaten most of the food and felled the closest trees around their dam, the colony will begin looking for a new home. Once abandoned, the beaver’s dam quickly deteriorates and the pond recedes, revealing a new wetland or meadow covered with rich, newly-fertilized soil where plants will quickly grow.
Did you know?
A beaver’s front teeth are very strong, and are sharpened by their chewing.
Beavers have bad eyesight, but a strong sense of smell and very good hearing. They do most of their construction work at night.
A beaver has furry paws on their front legs that are good at grabbing and holding building materials, and webbed toes on their back feet that are excellent for swimming.
Beavers warn each other of danger by slapping their wide tails against the water.
A beaver’s tail also helps them balance when carrying building materials, and steer themselves while swimming.
A beaver can hold its breath while underwater for up to 15 minutes.
Beavers’ building benefits the environment in many ways, including protecting endangered salmon and their habitat. Young salmon and trout find protection from predators in the complex currents and mazes of logs and branches surrounding beaver lodges and dams. Debris piles leftover from former beaver dams and lodges also protects the streams and creeks running through them from erosion.

The five-week government shutdown was a trying time for Forest Service employees and their families. Our partners, volunteers, permittees, and contractors were also impacted, as well as many businesses and communities closely tied to national forests and the work we do.
On behalf of the Forest Service employees across the Pacific Northwest, I want to thank everyone who stepped up to help and support our employees and the national forests during this challenging time.
We are grateful and touched by this outpouring of support. Citizens and businesses offered assistance to help employees make ends meet and care for their families.
State and local agencies chipped in to help protect and maintain recreation sites.
Dedicated volunteers came out in droves and partners carried on our shared conservation work.
Times like this underscore the importance of shared stewardship. Our shared commitment to public lands – and each other – drives everything we do.
Today, we are more interconnected and interdependent than ever before.
The opportunities and challenges we face transcend boundaries and impact people beyond the jurisdiction of any single agency or organization.
That’s why we are committed to working across boundaries in shared stewardship with states, partners, and local communities to support each other and accomplish shared objectives.
We’re glad to be back at work doing what we love – caring for the land and serving people.
We are currently assessing the shutdown’s impacts and determining how best to adjust to ensure we continue to deliver the services the public expects.
We will engage our partners and local communities in these conversations as we adapt and move forward together.
Service is one of our bedrock values.
We are heartened and humbled to know that when the need arises, our communities, partners, and the public we serve are here for us, too.
We thank you wholeheartedly for your support and look forward to continuing our work together in shared stewardship.
