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.

Mapping forest characteristics at fine resolution across large landscapes of the southeastern United States using NAIP imagery and FIA field plot data

Publications Posted on: May 10, 2018
Accurate information is important for effective management of natural resources. In the field of forestry, field measurements of forest characteristics such as species composition, basal area, and stand density are used to inform and evaluate management activities. Quantifying these metrics accurately across large landscapes in a meaningful way is extremely important to facilitate informed decision-making.

Assessing the impact of a mountain pine beetle infestation on stand structure of lodgepole pine forests in Colorado using the Forest Inventory and Analysis Annual forest inventory

Publications Posted on: June 01, 2017
The Forest Inventory and Analysis (FIA) annual inventory system began in Colorado in 2002, which coincided with the onset of a major mountain pine beetle (Dendroctonus ponderosae) epidemic.

Introduction to the Special Section on Forest Inventory and Analysis

Publications Posted on: May 24, 2017
Eighteen years ago, in this journal, Gillespie (1999) described the transition of the US Department of Agriculture (USDA) Forest Service Forest Inventory and Analysis (FIA) program from its historical practice of periodic, state-level inventories to a spatially and temporally balanced annualized inventory.

Forest Resources are inventories conducted as part of the national Forest Inventory and Analysis (FIA) program. Publications are listed alphabetically by forest name.

A tree-level model of forests in the western United States

Science Spotlights Posted on: September 14, 2016 of the number, size, and species of trees in forests across the western United States are desirable for a number of applications including estimating terrestrial carbon resources, tree mortality following wildfires, and for forest inventory. However, detailed mapping of trees for large areas is not feasible with current technologies. We used a statistical method called random forests for matching forest plot data with biophysical characteristics of the landscape in order to populate entire landscapes with a limited set of forest plot inventory data. 

 Invasibility of three major non-native invasive shrubs and associated factors in Upper Midwest U.S. forest lands

Publications Posted on: September 12, 2016
We used non-native invasive plant data from the US Forest Service’s Forest Inventory and Analysis (FIA) program, spatial statistical methods, and the space (cover class)-for-time approach to quantify the invasion potential and success ("invasibility") of three major invasive shrubs (multiflora rose, non-native bush honeysuckles, and common buckthorn) in broadly classified forest-type groups in seven Upper Midwest states.

Pinyon jays: Orchardists of the Great Basin’s woodlands

Science Spotlights Posted on: August 01, 2016
Over the past century, many pinyon-juniper woodlands in the Great Basin have expanded their range and increased their stand densities. These changes in structure and extent have effects on both the species that use the woodlands and to species whose habitat is being encroached by them. We observed and described where pinyon jays prefer to cache seeds in order to gain an understanding on how and where expansion and infill is likely to occur and to what extent jays are facilitating these processes.
