A watershed-scale monitoring protocol for bull trout

Publications Posted on: March 26, 2009
Bull trout is a threatened species native to the Pacific Northwest that has been selected as Management Indicator Species on several national forests. Scientifically defensible procedures for monitoring bull trout populations are necessary that can be applied to the extensive and remote lands managed by the U.S. Forest Service.

Forest Inventory and Analysis in the United States: Remote sensing and geospatial activities

Publications Posted on: November 07, 2007
Our Nation's forests provide a wealth of ecological, social, and economic resources. These forest lands cover over 300 million hectares of the United States, or about one third of the total land area. Accurate and timely information about them is essential to their wise management and use.

Field validation of Burned Area Reflectance Classification (BARC) products for post fire assessment

Publications Posted on: June 21, 2006
The USFS Remote Sensing Applications Center (RSAC) and the USGS EROS Data Center (EDC) produce Burned Area Reflectance Classification (BARC) maps for use by Burned Area Emergency Rehabilitation (BAER) teams in rapid response to wildfires. BAER teams desire maps indicative of soil burn severity, but photosynthetic and nonphotosynthetic vegetation also influences the spectral properties of post-fire imagery.

Analysis of landscape fragmentation in the Peloncillo Mountains in relation to wildfire, prescribed burning, and cattle grazing

Publications Posted on: June 09, 2006
This paper examined the application of state-of-the-art remote sensing image enhancement and classification techniques for mapping land cover change in the Peloncillo Mountains of Arizona and New Mexico. Spectrally enhanced images acquired August 1985, 1991, 1996, and 2000 were combined with environmental variables such as slope and aspect to map land cover modifications using a machine learning classifier.

The development of landscape-scale ecological units and their application to the greater Huachuca Mountains fire planning process

Publications Posted on: June 09, 2006
The multi-partner Greater Huachuca Mountains fire planning effort involves over 500,000 acres of public and private lands. This large area supports distinct landscapes that have evolved with fire.

Keeping wilderness wild: increasing effectiveness with limited resources

Publications Posted on: March 11, 2006
Wilderness managers are forced to make increasingly difficult decisions about where to focus limited resources. Traditionally, areas of high visitor use and high impact are prioritized over areas of light use and light impact. However, areas that contain little to no human impact and contain the qualities that lead to the area’s designation as wilderness are most precious and have the greatest potential to be responsive to management.
