User's Guide to the Stand Prognosis Model

Publications Posted on: May 12, 2016
The Stand Prognosis Model is a computer program that projects the development of forest stands in the Northern Rocky Mountains. Thinning options allow for simulation of a variety of management strategies. Input consists of a stand inventory, including sample tree records, and a set of option selection instructions. Output includes data normally found in stand, stock, and yield tables and details on selected sample trees.

The Northern Goshawk: Ecology and management: Proceedings of a symposium of the Cooper Ornithological Society

Publications Posted on: May 12, 2016
This collection of 22 papers summarizes the current state of knowledge on Northern Goshawks (Accipiter gentilis) within the scientific and management communities. The proceedings are presented in three sections. Research Approaches and Management Concepts contains overviews of research and management for goshawks, forest management to provide goshawk habitat, and field techniques.

Vegetation responsees to landscape structure at multiple scales across a Northern Wisconsin, USA, pine barrens landscape

Publications Posted on: May 12, 2016
Increasing awareness of the importance of scale and landscape structure to landscape processes and concern about loss of biodiversity has resulted in efforts to understand patterns of biodiversity across multiple scales. We examined plant species distributions and their relationships to landscape structure at varying spatial scales across a pine barrens landscape in northern Wisconsin, U.S.A.

Forest biogeochemistry in response to drought

Publications Posted on: April 23, 2016
Trees alter their use and allocation of nutrients in response to drought, and changes in soil nutrient cycling and trace gas flux (N2O and CH4) are observed when experimental drought is imposed on forests. In extreme droughts, trees are increasingly susceptible to attack by pests and pathogens, which can lead to major changes in nutrient flux to the soil.

Ponderosa pine resin defenses and growth: Metrics matter

Publications Posted on: April 21, 2016
Bark beetles (Coleoptera: Curculionidae, Scolytinae) cause widespread tree mortality in coniferous forests worldwide. Constitutive and induced host defenses are important factors in an individual tree’s ability to survive an attack and in bottom-up regulation of bark beetle population dynamics, yet quantifying defense levels is often difficult.

A principal component approach for predicting the stem volume in Eucalyptus plantations in Brazil using airborne LiDAR data

Publications Posted on: March 25, 2016
Improving management practices in industrial forest plantations may increase production efficiencies, thereby reducing pressures on native tropical forests for meeting global pulp needs. This study aims to predict stem volume (V) in plantations of fast-growing Eucalyptus hybrid clones located in southeast Brazil using field plot and airborne Light Detection andRanging (LiDAR) data.

Influence of mountain pine beetle epidemic on winter habitat conditions for Merriam's turkeys: Management implications for current and future condition

Publications Posted on: February 01, 2016
Understanding response of ponderosa pine (Pinus ponderosa) forest development following a mountain pine beetle (MPB; Dendroctonus ponderosae) epidemic has important management implications for winter habitat conditions for Merriam’s wild turkeys (Meleagris gallopavo merriami; hereafter, turkeys).

When are goshawks not there? Is a single visit enough to infer absence at occupied nest areas? Journal of Raptor Research

Publications Posted on: January 22, 2016
We tested the efficacy of three methods (historical nest search, broadcast search, and tree transect search) for detecting presence of the Northern Goshawk (Accipiter gentilis) at occupied nest areas during the 1994 breeding season using only a single visit to a previously known nest area. We used detection rates in a probability model to determine how many visits are required to have confidence in reporting absence of goshawks.

Seasonal resource selection of Canada lynx in managed forests of the northern Rocky Mountains

Publications Posted on: January 19, 2016
We investigated seasonal patterns in resource selection of Canada lynx (Lynx canadensis) in the northern Rockies (western MT, USA) from 1998 to 2002 based on backtracking in winter (577 km; 10 M, 7 F) and radiotelemetry (630 locations; 16 M, 11 F) in summer. During winter, lynx preferentially foraged in mature, multilayer forests with Engelmann spruce (Picea engelmannii) and subalpine fir (Abies lasiocarpa) in the overstory and midstory.

Wildfire Hazard Potential (WHP) for the conterminous United States (270-m GRID), version 2014 classified

Datasets Posted on: November 24, 2015
Federal wildfire managers often want to know, over large landscapes, where wildfires are likely to occur and how intense they may be. To meet this need we developed a map that we call wildfire hazard potential (WHP) – a raster geospatial product that can help to inform evaluations of wildfire risk or prioritization of fuels management needs across very large spatial scales (millions of acres).
