Priest River Experimental Forest weekly precipitation chemistry data: ID02

Datasets Posted on: February 03, 2016
This data package contains 2003 to present day precipitation chemistry data for the Priest River Experimental Forest, in Idaho, as reported to the National Atmospheric Deposition Program (NADP). Collected data include weekly calcium (Ca), magnesium (Mg), potassium (K), sodium (Na), ammonium (NH4), nitrate (NO3), chloride (Cl), and sulfate (SO4) levels in precipitation as well as the pH and other volumetric measurements.

Social conditions, conflict, and preference data for users in the Rattlesnake National Recreation Area in 1989

Datasets Posted on: August 27, 2015
This data publication contains visitor preference for naturalness and social conditions for their visitor experience in the Rattlesnake National Recreation Area (RNRA) and Wilderness in Montana. Random onsite interviews were conducted to gather basic on-site information regarding length of visit, travel destinations, and group characteristics.

Social conditions, conflict, and preference data for users in the Rattlesnake National Recreation Area in 1994

Datasets Posted on: August 27, 2015
The data available here highlight visitor preferences for naturalness and social conditions for their visitor experience in the Rattlesnake National Recreation Area (RNRA) and Wilderness in Montana. Mountain bikers and hikers in the RNRA were surveyed in 1994 to measure conflict between various user groups visiting the RNRA.

Reserved and roadless forests

Publications Posted on: November 20, 2009
Some 74 million acres of forest land, or 10 percent of all U.S. forest land, are permanently reserved from wood product utilization through statute or administrative designation. A large part of these lands is in wilderness areas, national parks, and national monuments.

Forest soils

Publications Posted on: November 20, 2009
Productive soils are the foundation of sustainable forests throughout the United States. Forest soils are generally subjected to fewer disturbances than agricultural soils, particularly those that are tilled, so forest soils tend to have better preserved A-horizons than agricultural soils.

Timber growth, mortality, and change

Publications Posted on: November 20, 2009
The previous section discussed trends in timber volume. Changes in volume often result from land-use change; that is, land entering or removed from the timber base. On those acres remaining forested, tree growth and mortality are the primary factors for volume change. Annual rates of growth and mortality often differ by species group, ownership, and geographic region.

Mapping forest resources of the United States

Publications Posted on: November 20, 2009
In this chapter, we present a collection of maps designed to portray the composition, structure, ownership, utilization, and spatial patterns of forest resources across the United States. This collection is the first comprehensive compilation of national-scale, forestry-related maps. These maps complement the information presented in the preceding chapters, but the maps and chapters are not directly dependent upon one another.

Timber growth, mortality, and change

Publications Posted on: September 30, 2009
Forest/> resource statistics from the 2000 Resources Planning Act (RPA) Assessment were updated to provide current information on the Nation's forests.

Assessing indicators of rangeland health with remote sensing in southeast Arizona

Publications Posted on: June 13, 2006
The goal of this study was to scale up ground-based range assessments to ranch and landscape scales in southeast Arizona using remote sensing and minimum amount of field data collection. Remotely sensed metrics of canopy cover, biomass, and mesquite composition were used to assess soil and site stability and biotic integrity.
