Ecology, silviculture, and management of Black Hills ponderosa pine

This paper presents a broad-based synthesis of the general ecology of the ponderosa pine ecosystem in the Black Hills. This synthesis contains information and results of research on ponderosa pine from numerous sources within the Black Hills ecosystem.

Of woodpeckers and harvests: Finding compatibility between habitat and salvage logging

The western United States is home to many woodpecker species that are strongly associated with recently disturbed forests, including post wildfire and post-beetle outbreaks. These types of landscapes are favored habitat because the dead and dying trees provide nesting and foraging substrates.

Regional habitat appraisals of wildlife communities: A landscape-level evaluation of a resource planning model using avian distribution data

A simple regional habitat model founded on the relation between vertical habitat complexity and species richness has been used to describe wildlife habitat in response to macroscale patterns in land use and land cover. While the model has a basis in ecological theory, it has not been subjected to rigorous testing.

Questionable multivariate statistical inference in wildlife habitat and community studies: A reply

We substantiate our contention that our multivariate analyses (Rexstad et al. 1988) mimic analyses found in the wildlife literature. We caution users of multivariate techniques that data collected in our discipline are unlikely to meet the restrictive assumptions of these techniques. Even if assumptions are met, we contend interpretation of the results is likely to lead to invalid inferences.

Questionable multivariate statistical inference in wildlife habitat and community studies

We analyzed a data set constructed from functionally unrelated, easily collected observations (e.g., meat, stock, and liquor prices) around Fort Collins, Colorado, using principal components analysis (PCA), canonical correlation analysis (CC), and discriminant function analysis (DFA). Each produced seemingly significant results and suggested strong relationships between the variables measured.

A framework for evaluating forest restoration alternatives and their outcomes, over time, to inform monitoring: Bioregional inventory originated simulation under management

The BioSum modeling framework summarizes current and prospective future forest conditions under alternative management regimes along with their costs, revenues and product yields.

GSD Update: Year in Review: Spotlight on 2016 Research by the Grassland, Shrubland and Desert Ecosystems Science Program

In this issue of the GSD Update, we take a look back at selected studies of the Grassland, Shrubland and Desert Ecosystems Science Program (GSD) that depict its strengths and focus areas. Significant results of recent research and science delivery by GSD scientists are highlighted. We feature program research that lines up with the strategic priorities of the USDA Forest Service and the Rocky Mountain Research Station (RMRS).
