Old-growth Logging the Culprit for Wolf Decline

This Audubon Alaska report shows how old-growth logging is the behind-the-scenes culprit in wolf declines on Prince of Wales Island in the Tongass National Forest.

In response to an Alaska Department of Fish and Game report in May that revealed a drastic decline in the wolf population on Prince of Wales and surrounding islands, Audubon Alaska’s science and policy team developed a report, Prince of Wales Wolves, examining the underlying reason for the decline: large-scale, old-growth, clearcut logging.

See the Audubon Alaska report and maps about how Big Thorne timber sale would harm wolf and deer on Prince of Wales.

The Big Thorne timber sale puts 120 million board feet of old-growth trees on the chopping block. It the largest timber sale on the Tongass in a decade. The sale takes from approximately 6,000 acres of forest on central Prince of Wales Island, which already has been severely logged.

One major concern with the sale is the effect it will have on Alexander Archipelago Wolves. Southeast Alaska wolf expert Dave Person sent comments to the Forest Service stating that the timber sale might result in eradicating wolves from Prince of Wales Island. In October 2013, The Forest Service put the Big Thorne timber sale on hold until the agency conducted more in-depth study of the effects of the massive logging on wolves (Read the Audubon Alaska press release). In May 2014, the agency said Big Thorne wouldn't affect wolves.

In June 2014, Audubon Alaska, working closely with wolf biologist Dave Person, submitted comments to the Forest Service that maps current and future impacts of 60 years of logging on Prince of Wales. Our results strongly suggest that the Forest Service got it wrong, that wolves are at very high risk on Prince of Wales. 


An introduction to the Tongass National Forest.


In early October 2013, the Forest Service announced it would make a "modification" to the Tongass Land Management Plan in order to begin the transition away from old-growth timber sales. “This announcement is a disappointing start," said Jim Adams, Policy Director for Audubon Alaska. "It doesn’t discuss the most important elements of any modification to the Tongass management plan.  There is no mention of ending clear-cut old-growth logging in 3 to 5 years to protect the wildlife and salmon of the Tongass.  And no mention of shifting the Forest Service’s focus to protecting and enhancing the fishing and tourism industries the region relies on for its economic future.” The amendment draft is expected to be released for public comment in November 2015.

Audubon at Work in the Tongass

In partnership with The Nature Conservancy (TNC), and with input from dozens of scientists, local residents, and resource managers, we have studied, analyzed, mapped, and described the coastal forests and mountains of Southeast Alaska to identify the most significant areas of highest ecological value in the region.

You can read our conservation assessment online, download our watershed matrix, view our Conservation Area Design Map (2.5MB, PDF format) and a gallery of Tongass resource maps, or download the Introduction.

With this science, Audubon Alaska and TNC have devised a place-based approach to protect and/or restore the most significant places within the Tongass. If we are to ensure the integrity of the Tongass ecosystem—including the abundant fish and wildlife populations that people use and care about—we must protect places like the Cleveland Peninsula, Honker Divide, Port Houghton, and the west side of Tenakee Inlet on Chichagof Island, to name a few.

The Audubon-TNC conservation assessment also identifies some places where both careful timber management and conservation could occur through forest restoration activities and second growth management for wildlife.

  • Ask your members of Congress to protect the Tongass National Forest.
    Suggested text: “I am writing to voice my support for the protection of the old-growth forests of the Tongass National Forest. The Tongass is our nation’s largest national forest and one of the most significant old-growth temperate rainforests on Earth. It is an important haven for productive populations of fish and wildlife that are rare or threatened elsewhere, and it is our last chance to protect the temperate rainforest at the ecosystem scale. Subsidized logging in the Tongass has cost American taxpayers nearly $1 billion dollars since 1982. I urge you to eliminate taxpayer subsidies on new roads in the Tongass, support a transition from old-growth timber harvest to second-growth harvest, and protect the spectacular American treasure that is the Tongass National Forest.”
