Effects of site preparation on root zone soil water regimes in high-elevation forest clearcuts

Documents and Media Posted on: October 10, 2018
Soil water deficits often reduce seedling growth and survival in the drier forested regions of southern British Columbia. This study investigated growing season soil water regimes on three clearcut, grass-dominated sites at different elevations in southern British Columbia to determine whether site preparation treatments could increase seedling root zone water supply.Document Type: Other Documents

Is resistance to mountain pine beetle associated with genetic resistance to white pine blister rust in limber pine?

Publications Posted on: October 04, 2018
Limber pine (Pinus flexilis James) co-evolved with the mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) and is now also challenged by the non-native pathogen Cronartium ribicola (J.C. Fisch.) that causes the lethal disease white pine blister rust (WPBR). Previous research suggests that trees infected with WPBR can be preferred hosts for MPB.

Northern New Mexico post-fire refugia data

Datasets Posted on: March 15, 2018
This publication contains spatial data, tabular data and scripts used to analyze the spatial patterns of refugia and associated plant communities following each of several fires in northern New Mexico. Four of the geotiff files were derived during the project (*Kernel.tif) using dNBR (delta Normalized Burn Ratio) or dNDVI (delta Normalized Difference Vegetation Index).

Calculating landscape surface area from digital elevation models

Publications Posted on: May 12, 2016
There are many reasons to want to know the true surface area of the landscape, especially in landscape analysis and studies of wildlife habitat. Surface area provides a better estimate of the land area available to an animal than planimetric area, and the ratio of this surface area to planimetric area provides a useful measure of topographic roughness of the landscape.

Digital surface, terrain, and canopy height models for the Bannock Creek unit of Boise Basin Experimental Forest in 2007

Datasets Posted on: August 27, 2015
The data publication contains 1 meter raster data sets for three different digital elevation models (DEM) for the Bannock Creek unit of the Boise Basin Experimental Forest in south central Idaho in November 2007. The first is a digital terrain model (DTM), which is the ground surface with all vegetation and human-made structures removed. The second is a digital surface model (DSM), which includes all vegetation and human-made structures.

Digital surface, terrain, and canopy height models for a portion of the Black Hills Experimental Forest in 2002

Datasets Posted on: August 27, 2015
The data publication contains 1 meter raster data sets for three different digital elevation models (DEM) for a portion of the Black Hills Experimental Forest in South Dakota in 2002. The first is a digital terrain model (DTM), which is the ground surface with all vegetation and human-made structures removed. The second is a digital surface model (DSM), which includes all vegetation and human-made structures.

Digital surface, terrain, and canopy height models for Priest River Experimental Forest in 2002

Datasets Posted on: August 27, 2015
The data publication contains 1 meter raster data sets for three different digital elevation models (DEM) for the Priest River Experimental Forest in north Idaho in 2002. The first is a digital terrain model (DTM), which is the ground surface with all vegetation and human-made structures removed. The second is a digital surface model (DSM), which includes all vegetation and human-made structures.

The forest fire season at different elevations in Idaho

Publications Posted on: August 06, 2015
In any fire-ridden forest region, such as north Idaho, there is great need for a tangible basis by which to judge the length and the intensity of the fire season in different forest types and at different elevations.

Field plot measures and predictive map products for "Regression modeling and mapping of coniferous forest basal area and tree density from discrete-return lidar and multispectral satellite data"

Datasets Posted on: March 27, 2015
This data publication contains lidar, advanced land imagery, geographic and tree data for 26 different predictor variables used in the modeling and mapping of basal area and tree density across two diverse coniferous forest landscapes in north-central Idaho. It also contains the Arc/INFO GRID raster format 30-meter-resolution maps for both study areas showing predicted basal area and tree density.

Subalpine vegetation pattern three decades after stand-replacing fire: Effects of landscape context and topography on plant community composition, tree regeneration, and diversity

Publications Posted on: March 08, 2010
These subalpine wildfires generated considerable, persistent increases in plant species richness at local and landscape scales, and a diversity of plant communities. The findings suggest that fire suppression in such systems must lead to reduced diversity. Concerns about post-fire invasion by exotic plants appear unwarranted in high-elevation wilderness settings.
