      The Southeast State Forest was the third and final State Forest to be voted in for Alaska. It spans alm acres in Southeast Alaska. 6) Bright orange mushrooms scatter the floors of Alaskan forests. Figure 4—Area (million acres) of forest and nonforest, southeast Alaska, L ESS THAN HALF OF southeast Alaska— million acres or 48 percent—is defined as forest land (figs. 2 and 4). The Tongass National Forest1 manages over 85 percent of the forest land in southeast Alaska; other federal agencies manage 5 percent, state and.

      The Forest Service has relied on a single forest measure, timber volume, to meet many management and planning information needs in southeast Alaska. This economic-based categorization of forest types tends to mask critical information relevant to other contemporary forest-management issues, such as modeling forest structure, ecosystem diversity.   A Stunning Rainforest In Alaska, Tongass National Forest Is The Largest In The U.S. Picture this: 17 million acres of huge trees, temperate rainforest, jolting fjords, booming waterfalls, steep mountain peaks, fascinating amounts of wildlife, glistening glaciers and some of the rarest types of flora and fauna in the world.

    The temperate rain forests of Southeast Alaska are dominated by western hemlock and Sitka spruce, but Alaska yellow‑cedar, western redcedar, shore pine and mountain hemlock are also important components. Wind is the major agent of large‑scale disturbance in Southeast Alaska causing uprooting and bole breakage. research findings in the report “Wind in the Forests of Southeast Alaska and Guides for Reducing Damage” (USFS PNW-GTR) or other pertinent research on this subject matter. We appreciate the opportunity to be involved in the planning of this important project. James Nielsen, Policy Chair Coos Chapter, OSAF P.O. Box Coos Bay, OR

The resulting climatic, site and silvicultural conditions have meant that foresters must address the issue of wind disturbance.

This includes damage to native forest aggregates and associated. The State's third and newest forest includes ab acres of land located in central and southern southeast Alaska. Many of the Forest's 32 management units are on Prince of Wales Island.

Other units are located on Dall, Gravina, Heceta, Kosciusko, Kuiu, Mitkof, Revillagigedo, Suemez, Tuxekan, and Wrangell islands. Southeast Alaska Weather: The climate in Ketchikan and the Southeast Alaska panhandle is a mid-latitude oceanic climate in the southern sections and a sub Arctic oceanic climate in the northern parts.

Much of the southern parts are temperate rainforest. On an annual basis, this is both the wettest and warmest part of Alaska with milder temperatures in the winter and high precipitation. The Alaskan rainforest is large — and largely undeveloped.

In Southeast Alaska alone there are hundreds of islands, 15, miles of coastline, over 19 million land acres, and over 5 million acres of pristine old-growth rainforest.

Most important — over 90% of the land in Southeast Alaska is public land — managed for you. That. Data from the Alaska Interagency Coordination Center. Circles represent the size, but not the shape, of the fire.

With inches of rain per year, the region is a temperate rainforest. Water is everywhere in the form of streams, lakes, bogs, and soggy vegetation. The forest undergrowth is lush with ferns and mosses.
