The Cooperative Alaska Forest Inventory (CAFI) is a comprehensive database of boreal forest conditions and dynamics in Alaska. The CAFI consists of fieldgathered information from numerous permanent sample plots distributed across interior and south-central Alaska including the Kenai Peninsula. The CAFI currently has 570 permanent sample plots on 190 sites representing a wide variety of growing conditions. New plots are being added to the inventory annually. To date, over 60 percent of the permanent sample plots have been remeasured and approximately 20 percent have been remeasured three times. Repeated periodic inventories on CAFI permanent sample plots provide valuable long-term information for modeling of forest dynamics such as growth and yield. Periodic remeasurements can also be used to test and monitor large-scale environmental and climate change. This guide documents sampling and estimation procedures of CAFI v.1.0, and provides details of the database, including attribute description and summary statistics. To help researchers and land managers successfully initiate or expand a permanent sample site program in Alaska, this guide offers a comprehensive tutorial to establish, maintain, and process permanent sample plots in Alaska's boreal forests.

Download A Path Toward Improved Management of the Northern Forests of Alaska Book in PDF, ePub and Kindle
This thesis provides three essential forest management tools that resource managers and researchers can use to improve management the northern forests of Alaska. The Cooperative Alaska Forest Inventory (CAFI) is a comprehensive database of northern forest conditions and dynamics. The basis for the CAH database is a system of permanent sample plots located throughout interior and south-central Alaska. This information can be used to develop forest growth models and track long-term forest changes. The bark thickness model was developed because there was no published white spruce bark thickness model for Alaska. The data used to develop this and volume models were taken from stands located throughout interior and south-central Alaska. Analysis shows that this Alaska statewide bark thickness model accuracy estimates white spruce bark thickness when compared to other bark thickness models. Cubic-foot volume models were developed to estimate total stem and merchantable volume of white spruce in Alaska. These multiple-entry (diameter and height) models estimate volume both outside and inside bark. Analysis shows that these volume models were more accurate for Alaska when compared to published and unpublished white spruce models. These models can be used to estimate individual stem volume, volume per unit area, and to develop biomass models.

Download The Forest Ecosystem of Southeast Alaska Book in PDF, ePub and Kindle
Southeast Alaska has 11.2 million acres of forest land, of which 4.9 million acres are considered commercial. This commercial acreage supports 166 billion board feet of sawtimber. These primarily old-growth stands of Sitka spruce and western hemlock are supporting a growing wood products industry that ranks first in the southeast economy and third in the State. This report summarizes current knowledge of the timber resource (areas, volumes, growth, mortality, quality, productivity, and trends) from the initial inventory, a partial remeasurement, and a second inventory now in progress. Historical data of wood products use, output, value, and markets are given and discussed. The report gives sources for much published and unpublished information for those who need to pursue these subjects more completely.

Download South-Central Alaska Forests Book in PDF, ePub and Kindle
This publication presents highlights of a recent south-central Alaska inventory conducted by the Pacific Northwest Research Station Forest Inventory and Analysis Program (USDA Forest Service). South-central Alaska has about 18.5 million acres, of which one-fifth (4 million acres) is forested. Species diversity is greatest in closed and open Sitka spruce forests, spruce woodlands, closed tall alder shrub type, and low shrub willow type. Of the forest land, 1.9 million acres are classified as timberland (unreserved productive forest land). About 1.3 million acres of forest land are reserved from harvest; these reserved forest acres are primarily on the Kenai National Wildlife Refuge, national parks, and the Chugach National Forest. The volume of timber on timberland was estimated at 5,087 million cubic feet; the plurality of volume44 percentis on state and local government lands with the remaining volume primarily on private lands (28 percent) and national forests (23 percent). Fifty-seven percent of timberland acres and 93 percent of the growing-stock volume is in sawtimber stands, with Sitka spruce forest type predominating. Most timberland in south-central Alaska is of relatively low productivity, producing less than 50 cubic feet per acre per year. For timberland acres on state and private lands, average annual mortality and harvest exceeded average annual growth.
