    Black Spruce forests represent 45% of the land cover in the interior of Alaska and are the prevailing forest type in Alaskan (66% of Alaskan forests) and Canadian boreal forests. These forests occur primarily in areas with discontinuous permafrost, which can greatly influence site drainage conditions and the organic soil layer thickness (Hoy et. trol aspen, white spruce, and black spruce stands located within km of the town of Tok Junction, Alaska (Fig. 1).

Black spruce waits out other tree species, pops up in the understory, grows slowly, and stays anchored in cool soil unless the forest burns, is cut down, gets chewed up by river ice or meets some.

Additional Physical Format: Online version: Preliminary results of experimental fires in the black spruce type of Interior Alaska. Portland, Or.: Pacific Northwest Forest and Range Experiment Station, U.S. Dept. of Agriculture, Forest Service, []. Black spruce communities are widely distributed in boreal Alaska.

Around 30% to 40% of Alaska's landscape is boreal forest [], and black spruce is the most common boreal forest type [23,].Black spruce communities are especially common in interior Alaska, occupying 39% to 44% of that region [].Alaskan black spruce communities typically occur on cold, poorly drained, nutrient-poor sites with.

FIRE DESCRIPTION AND EFFECT ON FUELS AND SOIL: Objectives: The fire management objectives were to: 1) measure fire behavior under prescribed conditions in the black spruce/feather moss type of interior Alaska and 2) determine the effects of fires of different severities on vegetation, the soil organic layer, and soil nutrients.

Fire in the black spruce ecosystem of northern Canada and Alaska is characterized by large and frequent fires that usually kill the overstorey trees and most, if not all, of the vegetation aboveground.

Most species within the black spruce ecosystem show adaptations to fire, and black spruce stands are usually perpetuated by fire. Depending on the site, revegetation follows one.

Boreal forests contain large amounts of stored soil carbon and are susceptible to periodic disturbance by wildfire. This study evaluates the relationship between post-fire changes in soil temperature, moisture, and CO2 exchange in paired burned and control stands of three Alaskan forest systems: Picea mariana (Mill.) BSP, Picea glauca (Moench) Voss, and Populus tremuloides.

Methods Overview and study area This study was carried out using remote sensing observations obtained from Landsat 5 and 7 (TM and ETM+) and field data from black spruce sites within two separate fire events that burned during the summer of in interior Alaska (Fig. 1; the Boundary Fire (n=28 sites) and the Porcupine.

During andwe measured forest vegetation structure and composition on one hundred and thirty-six m?. m plots to assess both the immediate stand and landscape level effects of the spruce beetle infestation.

In Interior Alaska, where white spruce has long been one of the dominant forest species, the trees are struggling, with "markedly lower growth" than at any time since the 19th century, the study.

Because of the vast acreage in Alaska and the potentially high C storage capacity in the boreal forest zone, an understanding of black spruce dominated sites is important for both ecological modeling and for land management.
