Tongass National Forest Explained

Introduction

The moment you step off your cruise ship or aircraft in Juneau, you will be immediately treated to stunning views of the Tongass National Forest. Fact. Unsurprising to most, the region is often referred to as the “Inside Passage” or the gateway to Alaska. Undeniably, it’s one of the country’s—even the world’s—greenest, biomass hotspots. It’s impossible to miss, primordially shrouded in mist most days, awaiting your pleasure.

At approximately 17 million acres, the Tongass National Forest is America’s largest national forest, encompassing the majority of the southeast Alaska Panhandle. Rising from the deep, rich waters of Alaska’s Inside Passage, southeast Alaska is a land of ancient forests, mountains and glaciers. This temperate rainforest is a land shaped by the forces of water. Water stored in glaciers creeps out to the sea in titanic rivers and tiny streams. Water falls as rain, mist and snow and feeds the forest. The sea carves the coast while bringing nutrients from thousands of miles away deep inland.

Decades of clear-cutting has cost the Tongass portions of its best habitat, and yet the forest still contains some of the most intact expanses of temperate rainforest remaining in the world. It is home to five species of Pacific salmon, humpback and orca whales, otters, beavers, Alexander Archipelago wolves, plus some of the largest concentrations of brown bears and bald eagles found in the United States.

Its giant old-growth trees are also a warehouse of carbon, helping regulate the planet’s climate.

American Forests

Forests entrance people from all walks of life, and though it would be hard to select the “best” or “most amazing,” some forests simply take your breath away. Tongass National Forest in Juneau and numerous other parts of Alaska, is one of these places. Referred to as the crown jewel of the national forest system, Tongass has numerous qualities to tout. It is the largest national forest, covering more than 17 million acres. It also possesses the biggest reserve of coastal temperate rainforest in the world, which is the rarest and most valuable type of forest. There are 19 designated wilderness areas within the forest, more than any other national forest. And this is only the beginning.” Jami Westerhold, American Forests’ director of strategic initiatives.

 

Top Facts

  • The largest national forest in the USA and largest intact temperate rainforest in the world: namely, it is the size of West Virginia or the Republic of Ireland.
  • The rainforest extends from Kodiak Island along the coast to California “fogbelt” redwoods.
  • Home to 70,000 people where Alaska Natives have inhabited the Tongass for 10,000+ years.
  • Tongass waters house 128 glaciers; all 5 species of Pacific salmon.
  • Some trees are up to 1,000 years old where the forest is home to: hemlock (at higher elevations), Sitka spruce (shoreline specialists) and yellow and red cedar (in between).
  • About 90 per cent of the old growth regions of the forest remain as they were 100 years ago.
  • Average rainfall ranges from 26-inches in Skagway to 225-inches on Baranof Island.
  • Unlike most places in the Lower 48, it is wind, and not fire that disturbs the forest in small-scale disturbances, although still toppling acres of trees at a time in blow downs and avalanches. (Moderate temperatures where summer temperatures average in the 50Fs to 60Fs and very high rainfall make fires extremely rare.)
  • Because the temperatures are cool, the material is broken down, decayed and recycled much more slowly than in the tropical rainforest. Scientists have measured more biomass (living things) in each square yard of this forest than anywhere else on earth. Coastal temperate rainforests accumulate and store more organic matter than any other forest type—as much as 500-2,000 metric tons of wood, foliate, leaf litter, moss, other living plants and soil per hectare.
  • The marine waters adjacent to the Tongass are productive as well. The upwelling zones and cold-water currents that bathe the edges of coastal temperate rainforests account for a substantial share of the biological production of the oceans.
  • The productivity of coastal temperate rainforest ecosystems is enhanced by the nutrients and organic debris washed out of coastal watersheds, epitomizing the concept ecologists call “ecotones”—zones of transition between adjacent ecological systems.
  • The seven anadromous (migrating up rivers from the sea to spawn) species of Pacific salmon and trout, which range widely in the North Pacific before returning to their natal coastal rainforest steams to spawn, dramatically demonstrate the reciprocity of forest and sea.
  • Protects 90 per cent of the Alaska Panhandle.
  • More than a quarter of the world’s coastal temperate rainforests occur in the North Pacific coastal forests eco-region of southeast Alaska.
  • Less than 80 per cent of the Tongass National Forest is developed, primarily from past timber management activities.

History

People and the Tongass National Forest

Alaska Natives have continuously inhabited southeast Alaska and the Tongass for thousands of years, depending on the bounty of salmon, deer and moose for subsistence. The first nations include the Tlingit, Haida and Tsimshian, and the forest itself is named for the Tongass group of the Tlingit people, who inhabited the southernmost areas of southeast Alaska, near what is now the city of Ketchikan. Dependence on the land is still a way of life here, a cultural tradition as well as a necessity, made possible by the abundance of fish and wildlife in the region.

Today, the Tongass is home to approximately 70,000 people spread among 32 communities, including approximately 32,000 in the state capital of Juneau. The region is defined by its primary industries with commercial fishing, tourism and recreation jobs among the fastest growing job sectors in southeast Alaska. These industries pump approximately $1 billion apiece into southeast Alaska’s economy annually and support approximately 7,200 jobs (fishing) and 10,000 jobs (tourism) respectively.

Alaska Native Claims Settlement Act

In 1971, the Alaska Native Claims Settlement Act (ANCSA) authorized native local and regional corporations to select and receive title to a combined 44 million acres of public land in Alaska. ANCSA was intended to resolve the long-standing issues surrounding aboriginal land claims in Alaska, an important and necessary resolution.

However, the recently introduced Southeast Alaska Native Land Entitlement Finalization and Jobs Protection Acts (S. 730 and H.R. 1408) would re-open the ANCSA agreement, allowing Sealaska Corporation, a native Alaskan company, to select and receive titles to publicly owned lands—administered by the U.S. Forest Service—not included in the original agreement.

Allocation of protected land

This legislation would allocate 65,000 acres of protected public land within Tongass to Sealaska for logging and development. These acres are considered valuable public lands and contain a large quantity of very-large-tree, old growth forests. A report by Audubon Alaska estimates that the small and scattered parcels selected by Sealaska would increase the company’s ownership of very-large-tree, old growth areas by twelvefold.

Logging and elimination of old practices

While these large-tree stands only account for 1.6 percent of the productive old growth in Tongass, the Alaskan timber industry has a history of focusing its logging on the largest and most valuable old-growth trees of Tongass, and old-growth areas represent up to 27 percent of the lands Sealaska has selected.

Though the Tongass Timber Reform Act of 1989 eliminated the practice of high grading—the disproportionate logging, relative to occurrence, of the largest and most valuable trees—the land selected in this legislation indicates a threat of a return to the practice. It is estimated that more than half of the large-tree, old growth areas have been logged in Tongass, and with this legislation, Sealaska could log almost 17 percent of the remaining stands.

Achieving a delicate balance

Weighing competing interests of protecting the Tongass as untouched wilderness area, versus human intervention for increased access for recreational purposes and harvesting trees for wood products, is what determines how we can manage our public lands’ natural resources. Achieving and maintaining this balance is often like walking a tight rope, moving too far to one side alters the equilibrium of everything else.

Being the home of the majority of America’s remaining old-growth forests, which hold more organic matter per acre than any other forest, including tropical rainforests, the scale clearly tips towards Tongass’ preservation.

Co-existence of humans and wilderness

As Tongass has always been a place where people and wilderness co-exist, the Southeast Alaska communities are dependent on the health and abundance of this forest to sustain their livelihoods and cultures. America’s most precious and endangered forests are far more valuable standing than cut down.

Conclusion

As President Theodore Roosevelt once said, “To exist as a Nation, to prosper as a State and to live as a people, we must have trees.” Though Tongass may not be in your backyard, it is unquestionably a national treasure that must be protected. However small, when combined with the actions of others, your individual actions can impact real and tangible outcomes for the preservation of the Tongass and the ultimately, the planet.
