Quantifying ecological integrity of terrestrial systems to inform management of multiple-use public lands in the United States

Publications Posted on: April 16, 2019
The concept of ecological integrity has been applied widely to management of aquatic systems, but still is considered by many to be too vague and difficult to quantify to be useful for managing terrestrial systems, particularly across broad areas.

Nevada's forest resources, 2004-2013

Publications Posted on: December 12, 2016
This report presents a summary of the most recent inventory information for Nevada’s forest lands. The report includes descriptive highlights and tables of area, number of trees, biomass, volume, growth, mortality, and removals. Most of the tables are organized by forest-type group, species group, diameter class, or ownership. The report also describes inventory design, inventory terminology, and data reliability.

Nevada Photo-Based Inventory Pilot (NPIP) resource estimates (2004-2005)

Publications Posted on: March 21, 2016
The complex nature of broad-scale, strategic-level inventories, such as the Forest Inventory and Analysis program (FIA) of the USDA Forest Service, demands constant evolution and evaluation of methods to get the best information possible while continuously increasing efficiency. The State of Nevada is predominantly comprised of nonforested Federal lands with a small proportion of forest land dominated by non-commercial, woodland tree species.

The effect of planting depth on emergence of 20 native forbs

Projects Posted on: January 22, 2015
This project studies the seedbed ecology requirements of native forbs, particularly the appropriate seeding depth in loam textured soils.

Field testing provisional seed zones for basin wildrye

Projects Posted on: January 22, 2015
In the effort to use genetically appropriate plant materials for restoration projects, provisional seed zones were developed as one method of pairing seed sources to restoration sites. 

Forest inventory and analysis tree-ring data archive and analysis

Projects Posted on: January 22, 2015
The Interior West Forest Inventory and Analysis (FIA) Program collects increment cores as part of regular monitoring. Ring-widths from these increment cores are being digitized and assembled into data products for biogeographical or climatological analyses. 

Influences of watershed geomorphology on extent and composition of riparian vegetation

Publications Posted on: September 27, 2011
Watershed (drainage basin) morphometry and geology were derived from digital data sets (DEMs and geologic maps). Riparian corridors were classified into five vegetation types (riparian forest, riparian shrub, wet/mesic meadow, dry meadow and shrub dry meadow) using high-resolution aerial photography. Regression and multivariate analyses were used to relate geomorphic characteristics to riparian vegetation extent and composition.

Using interpreted large scale aerial photo data to enhance satellite-based mapping and explore forest land definitions

Publications Posted on: July 20, 2009
The Interior-West, Forest Inventory and Analysis (FIA), Nevada Photo-Based Inventory Pilot (NPIP), launched in 2004, involved acquisition, processing, and interpretation of large scale aerial photographs on a subset of FIA plots (both forest and nonforest) throughout the state of Nevada.

Aspen community types of the Intermountain Region

Publications Posted on: May 15, 2009
This vegetation classification is based upon existing community structure and composition in the aspen-dominated forests of the Intermountain Region of the Forest Service. The 56 community types occur within eight tree-cover types. A diagnostic key using indicator species facilitates field identification of the community types. Vegetational composition, productivity, and successional status are included.

Nevada Photo-Based Inventory Pilot (NPIP) photo sampling procedures

Publications Posted on: March 19, 2009
The Forest Inventory and Analysis program (FIA) of the U.S. Forest Service monitors status and trends in forested ecoregions nationwide. The complex nature of this broad-scale, strategic-level inventory demands constant evolution and evaluation of methods to get the best information possible while continuously increasing efficiency.
