Interior West Forest Inventory & Analysis: New Mexico

Pages Posted on: July 10, 2019
Inventory and monitoring efforts conducted by Rocky Mountain Research Station scientists present a systematic compilation of forest statistics of the state.

Fire Lab tree list: A tree-level model of the western US circa 2009 v1

Datasets Posted on: March 15, 2018
Maps of the number, size, and species of trees in forests across the western United States are desirable for many applications such as estimating terrestrial carbon resources, predicting tree mortality following wildfires, and for forest inventory.

Painting a picture across the landscape with ModelMap

Publications Posted on: September 08, 2017
Scientists and statisticians working for the Rocky Mountain Research Station have created a software package that simplifies and automates many of the processes needed for converting models into maps. This software package, called ModelMap, has helped a variety of specialists and land managers to quickly convert data into easily understood graphical images. The software package also includes methods to test for accuracy.

Can FIA soils data improve models predicting ponderosa pine density in the Southwest?

Projects Posted on: August 25, 2017
Puhlick et al. (2012) evaluated the influence of numerous abiotic and biotic factors on ponderosa pine regeneration densities in the southwestern United States. The study described here will use newly released soils data from the Forest Inventory and Analysis program to test the influence of soils and other variables on ponderosa pine seedling densities.

Gridded snow water equivalent reconstruction for Utah using Forest Inventory and Analysis tree-ring data

Publications Posted on: July 19, 2017
Snowpack observations in the Intermountain West are sparse and short, making them difficult for use in depicting past variability and extremes. This study presents a reconstruction of April 1 snow water equivalent (SWE) for the period of 1850–1989 using increment cores collected by the U.S. Forest Service, Interior West Forest Inventory and Analysis program (FIA).

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.

Changes in snag populations on National Forest System lands in Arizona, 1990s to 2000s

Publications Posted on: December 30, 2016
Snags receive special management attention as important components of forest systems. We used data from the US Department of Agriculture (USDA) Forest Service Forest Inventory and Analysis Program, collected during two recent time periods (1995 to 1999 and 2001 to 2010), to evaluate trends in snag populations in two forest types in Arizona. Densities of snags ≥4 in.

FIA publications: Forest Resources

Pages Posted on: October 20, 2016
Forest Resources are inventories conducted as part of the national Forest Inventory and Analysis (FIA) program. Publications are listed alphabetically by forest name.

Evaluating cost-effectiveness of multi-purpose fuel treatments in western dry mixed-conifer forest considering hazard, risk, longevity, and co-benefits

Projects Posted on: August 18, 2016
The research objective is to evaluate the effectiveness and cost-effectiveness of a broad range of fuel treatment designs, patterned on treatments applied to dry mixed conifer forest, which address multiple components of resistance to fire in diverse forest settings. The project design accounts for fuel treatment longevity by considering and comparing the effectiveness and costs of treatment over a multi-decade planning horizon, addressing the challenge of rating cost-effectiveness in the context of multiple treatment and land management objectives, and providing a framework for assessing the stand-level effects of fuel treatment on fire behavior and resistance to fire.

Mapping aboveground biomass annually across the northwestern USA from LiDAR and Landsat image time series

Projects Posted on: August 18, 2016
The cumulative area of LiDAR collections across multiple ownerships in the northwestern USA has reached the point that land managers of the USDA Forest Service (USFS) and other stakeholders would greatly benefit from a strategy for how to utilize LiDAR for regional aboveground biomass inventory. The need for Carbon Monitoring Systems (CMS) can be more robustly addressed by using not only available NASA satellite data products, but also commercial airborne LiDAR data collections.
