Regenerating white spruce, paper birch, and willow in south-central Alaska1 E.C. Cole, M. Newton, and A. Youngblood Abstract: The current spruce bark beetle (Dendroctonus rufipennis Kirby) epidemic in interior Alaska is leaving large expanses of dead spruce with little spruce regeneration. Many of these areas are habitat for moose (Alces alces). To. Natural regeneration of many North American conifer species frequently occurs in association with the hair-cap mosses (Polytrichum spp.), common and widely distributed pioneer mosses of boreal and temperate coniferous role of Polytrichum mosses in the natural regeneration of white spruce (Picea glauca (Moench) Voss) was investigated through a comparative study of .
Under all warming scenarios, the most successful regenerating species following white spruce harvest is white spruce. Birch experiences about 30% regeneration failure under A2 scenario by White spruce and aspen are projected to regenerate more successfully when site preparation is applied. In interior Alaska, increased use of mechanical fuel reduction treatments, increased interests in the use of wood energy systems as alternatives to fossil fuels, and elevated populations of northern spruce engraver, Ips perturbatus (Eichhoff), have raised concerns regarding the impact of this bark beetle to forest resources. We conducted a large-scale field study in − (Study 1) to.

Guidelines for obtaining natural regeneration of white spruce in Alaska. [John C Zasada; United States. Forest Service.; Pacific Northwest Forest and Range Experiment Station (Portland, Or.)] -- Gives basic requirements for natural regeneration of white spruce.
Also methods for creating conditions to meet these requirements. Reforestation options for artificial regeneration of white spruce (Piceaglauca (Moench) Voss) were tested on three floodplain sites near Fairbanks, al of containerized seedlings after outplanting was above 96%, regardless of harvest cutting method or mechanical site preparation, and declined little between the third and fifth growing seasons.
Regeneration surveys on nine logged areas in the vicinity of Fairbanks, Alaska indicated low levels of white spruce (Piceaglauca (Moench.)Voss.) regeneration.
In view of the limited field data, Monte Carlo simulation methods were used to estimate the probabilities of obtaining various levels of white spruce stocking by the 1st and 10th years after logging. The current spruce bark beetle (Dendroctonus rufipennis Kirby) epidemic in interior Alaska is leaving large expanses of dead spruce with little spruce of these areas are habitat for moose (Alces alces).To establish spruce regeneration and improve browse production for moose, paper birch (Betula papyrifera Marsh), willow (Salix spp.), and three stocktypes (plug+1 bareroot, and.
White spruce is a medium-sized (occasionally >55 m tall), evergreen conifer, with a fairly symmetrical, conical crown, a regular branching pattern that often extends to the ground, and a smooth, dark gray, scaly bark.
The wood of white spruce is light, straight grained, and resilient. It is used primarily for lumber and pulp. The timing of white spruce regeneration in aspen (Populus tremuloides Michx.) white spruce (Picea glauca (Moench) Voss) boreal mixedwood stands is an important factor in stand examined boreal mixedwood stands representing a year period of time since fire and determined (1) whether and when a delayed regeneration period of white spruce occurred, (2) whether the relative.

Get this from a library. A key for predicting postfire successional trajectories in black spruce stands of Interior Alaska. [Jill Frances Johnstone; Teresa Nettleton Hollingsworth; F Stuart Chapin, III; Pacific Northwest Research Station (Portland, Or.)] -- Black spruce (Picea mariana (Mill) B.S.P) is the dominant forest cover type in interior Alaska and is prone to frequent, stand-replacing.
A long term perspective on several quasi-decadal cycles of intensifying drought stress across boreal Alaska has been synthesized from monitoring of forest reference stands at Bonanza Creek LTER, Interior Alaska Research Natural Areas, and tree ring sampling across Alaska.
The Alaska boreal forest is largely made up of tree populations with two growth responses to temperature increases. Picea glauca, the white spruce, is a species of spruce native to the northern temperate and boreal forests in North America.
Picea glauca was originally native from central Alaska all through the east, across southern/central Canada to the Avalon Peninsula in Newfoundland. It now has become naturalized southward into the far northern United States border states like Montana, Minnesota.
White spruce regeneration density is also affected greatly by sporadic seed production (Juday et al.,Roland et al., ). White spruce is a masting (Kelly, ) species and produces large seed crops only about every 10 years in boreal Alaska (Juday et al.,Roland et al., ).
A spruce is a tree of the genus Picea / p aɪ ˈ s iː ə /, a genus of about 35 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal regions of the s are large trees, from about 20–60 m (about 60– ft) tall when mature, and have whorled branches and conical form.
They can be distinguished from other members of the pine. white spruce forests of Alaska. Spruce bark beetles, fires, and timber harvests have left millions of acres of dead spruce with little spruce regeneration. To assist public and private landowners, Pacific Northwest Research (PNW) Station scientists are test-ing various approaches to white spruce regeneration.
In search of a competitive. 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.White Spruce Trailer Sales is a trailer dealership located in Anchorage, AK.
