Summary and findings of the 2006 BLM Forest Lands Report

Publications Posted on: July 20, 2009
In 2006, the Bureau of Land Management (BLM) contracted with the Forest Service Forest Inventory and Analysis Program (FIA) to assist in the preparation of a report specific to all forest lands under the administration of the BLM. The BLM requested that the FIA provide information on the extent and general conditions of BLM- managed forests and woodlands, within certain statistical reliability parameters.

Use of damage surveys and field inventories to evaluate oak and sugar maple health in the northern United States

Publications Posted on: July 20, 2009
Oak species (Quercus spp.) and sugar maple (Acer saccharum) are substantial components of the forest ecosystems in the 24-state region spanning the northern U.S. During recent decades, both damage surveys and forest inventories have documented declines of sugar maple and oak health.

Evaluating cypress sustainability - "FIA in the hot seat"

Publications Posted on: July 20, 2009
The use of cypress (Taxodium species) for mulch boomed during the 1990s, and its growth in popularity created concerns about the sustainability of cypress forests in the Southern United States. A combination of factors, including Hurricane Katrina, cypress harvesting practices, and the unique requirements for successful regeneration of cypress drew media attention and fueled debates over sustainability of cypress forests.

From detection monitoring to evaluation monitoring - a case study involving crown dieback in northern white-cedar

Publications Posted on: July 20, 2009
The Forest Inventory and Analysis (FIA) Phase 3 plot network is a crucial part of the U.S. Forest Health Monitoring program's detection monitoring system, where select indicators are monitored for signals that may indicate deteriorating forest health. When a negative signal is identified, evaluation monitoring provides a mechanism whereby a potential problem can be further investigated.

Investigation into calculating tree biomass and carbon in the FIADB using a biomass expansion factor approach

Publications Posted on: July 15, 2009
The official U.S. forest carbon inventories (U.S. EPA 2008) have relied on tree biomass estimates that utilize diameter based prediction equations from Jenkins and others (2003), coupled with U.S. Forest Service, Forest Inventory and Analysis (FIA) sample tree measurements and forest area estimates.

Harmonizing estimates of forest land area from national-level forest inventory and satellite imagery

Publications Posted on: July 15, 2009
Estimates of forest land area are derived both from national-level forest inventories and satellite image-based map products. These estimates can differ substantially within subregional extents (e.g., states or provinces) primarily due to differences in definitions of forest land between inventory- and image-based approaches. We present a geospatial modeling approach for redefining satellite image-based pixels to meet inventory definitions.

Mountain pine beetle infestations and Sudden Aspen Decline in Colorado: Can the Forest Inventory and Analysis annual inventory system address the issues?

Publications Posted on: July 15, 2009
There are two events occurring in Colorado that are concerning forest managers in Colorado. There is severe and widespread mortality of lodgepole pine due to the mountain pine beetle and aspen forests in some areas of the state have experienced widespread, severe, and rapid crown deterioration leading to mortality.

Combining forest inventory, satellite remote sensing, and geospatial data for mapping forest attributes of the conterminous United States

Publications Posted on: July 15, 2009
Analysis and display of forest composition, structure, and pattern provides information for a variety of assessments and management decision support. The objective of this study was to produce geospatial datasets and maps of conterminous United States forest land ownership, forest site productivity, timberland, and reserved forest land.

Design tool for inventory and monitoring

Publications Posted on: July 15, 2009
Forest survey planning typically begins by determining the area to be sampled and the attributes to be measured. All too often the data are collected but underutilized because they did not address the critical management questions.

Overview of the National Inventory and Monitoring Applications Center (NIMAC)

Publications Posted on: July 15, 2009
The National Inventory and Monitoring Applications Center (NIMAC) was created by the Forest Inventory and Analysis (FIA) program in 2006. NIMAC addresses a growing need, expressed by FIA partners, for technical assistance in designing and implementing monitoring plans for forests at scales finer than that provided by the FIA standard inventory.
