Idaho’s forest resources, 2006-2015

Publications Posted on: December 13, 2018
This report presents a summary of the most recent Forest Inventory and Analysis data of Idaho’s forests based on field data collected between 2006 and 2015. The report includes descriptive highlights and tables of area, numbers of trees, biomass, volume, growth, mortality, and removals. Most sections and tables are organized by forest type or forest-type group, tree species group, diameter class, or owner group.

Idaho's Forest Products Industry: A Descriptive Analysis

Publications Posted on: August 01, 2018
This report provides a description of the structure, capacity, and condition of Idaho's primary forest products industry; traces the flow of Idaho's 2001 timber harvest through the primary sectors; and quantifies volumes and uses of wood fiber. The economic contribution of the forest products industry to the State and historical industry changes are discussed, as well as trends in timber harvest, production, and sales.

Forest Service science bolsters sagebrush and sage-grouse conservation

Media Gallery Posted on: September 16, 2016
Sagebrush ecosystems are among the largest and most threatened ecosystems in North America. Greater sage-grouse has served as the bellwether for species conservation in these ecosystems and has been considered for listing under the Endangered Species Act several times. The 2016 Conservation and restoration of sagebrush ecosystems and sage-grouse: An assessment of USDA Forest Service Science assessment will help meet continuing widespread concerns and calls for science-based conservation to mitigate threats to sagebrush ecosystems, conserve populations of sage-grouse and other sagebrush-obligate species, and restore sagebrush ecosystems throughout the western United States. 

Forest Service science bolsters sagebrush and sage-grouse conservation

Science Spotlights Posted on: August 19, 2016
USDA Forest Service (FS) has been a leader for several decades in developing science and applications to support conservation and restoration of sagebrush ecosystems and sage-grouse populations. This spotlight describes an assessment that explains how and why understanding and supporting FS science is crucial for future management of sagebrush ecosystems.

Occupancy of red-naped sapsuckers in a coniferous forest: Using LiDAR to understand effects of vegetation structure and disturbance

Publications Posted on: July 28, 2016
Red-naped sapsuckers (Sphyrapicus nuchalis) are functionally important because they create sapwells and cavities that other species use for food and nesting. Red-naped sapsucker ecology within aspen (Populus tremuloides) has been well studied, but relatively little is known about red-naped sapsuckers in conifer forests.

Avian relationships with wildfire at two dry forest locations with different historical fire regimes

Publications Posted on: May 20, 2016
Wildfire is a key factor influencing bird community composition in western North American forests. We need to understand species and community responses to wildfire and how responses vary regionally to effectively manage dry conifer forests for maintaining biodiversity. We compared avian relationships with wildfire burn severity between two dry forest locations of Arizona and Idaho.

Lichen communities indicator results from Idaho: baseline sampling

Publications Posted on: May 12, 2016
Epiphytic lichen communities are included in the national Forest Health Monitoring (FHM) program because they help us assess resource contamination, biodiversity, and sustainability in the context of forest health. In 1996, field crews collected lichen samples on 141 field plots systematically located across all forest ownership groups in Idaho. Results presented here are the baseline assessment of the statewide field survey.

Modeling relationships between landscape-level attributes and snorkel counts of chinook salmon and steelhead parr in Idaho

Publications Posted on: May 12, 2016
Knowledge of environmental factors impacting anadromous salmonids in their freshwater habitats, particularly at large spatial scales, may be important for restoring them to previously recorded levels in the northwestern United States.

An evaluation of multipass electrofishing for estimating the abundance of stream-dwelling salmonids

Publications Posted on: May 12, 2016
Failure to estimate capture efficiency, defined as the probability of capturing individual fish, can introduce a systematic error or bias into estimates of fish abundance.

Snow catch by conifer crowns

Publications Posted on: August 14, 2015
Study of interception storage of snow by two species of sapling conifers in northern Idaho revealed that cumulative snow catch follows the classical law of autocatakinetic growth, or [equation - see PDF] where I, is interception storage, e is the interception storage capacity of the tree, e is the base of the natural logarithm, k is a constant expressing the rate of interception storage, P is accumulated snowfall, and Po is accumulated snowfal
