Silvicultural options for open forest management in eastern North America

Publications Posted on: July 11, 2020
Fire-sustained open oak and pine forests were once widespread across eastern North America, but are now comparatively scarce. To regain the goods and services of these open forests, managers are increasingly looking to restore them with the silvicultural systems and tools best suited to meet their objectives.

Chapter 1: A conservation assessment framework for forest carnivores.

Publications Posted on: June 22, 2020
Controversy over managing public lands is neither an unexpected nor recent development. In the 1970's, debate over land management began to focus on the effects of timber management practices on wildlife. This was most evident in the Pacific Northwest where the public was beginning to express strong concerns about the effects of timber harvest in late-successional forests on northern spotted owls and other vertebrates.

Using decision analysis to support proactive management of emerging infectious wildlife diseases

Publications Posted on: June 19, 2017
Despite calls for improved responses to emerging infectious diseases in wildlife, management is seldom considered until a disease has been detected in affected populations. Reactive approaches may limit the potential for control and increase total response costs.

Assessment of native species and ungulate grazing in the Southwest: Terrestrial wildlife

Publications Posted on: May 12, 2016
Range managers in the Southwestern States are increasingly being required to develop management strategies that take into consideration the conservation of wildlife populations. However, information on many aspects of the fundamental biology and impacts of grazing on individual species is still lacking in the scientific and government literature.

Chapter 6: The scientific basis for conserving forest carnivores: considerations for management

Publications Posted on: May 12, 2016
The reviews presented in previous chapters reveal substantial gaps in our knowledge about marten, fisher, lynx, and wolverine. These gaps severely constrain our ability to design reliable conservation strategies. This problem will be explored in depth in Chapter 7. In this chapter, our objective is to discuss management considerations resulting from what we currently know (and don't know) about these four forest carnivores.

Chapter 7: Information needs and a research strategy for conserving forest carnivores

Publications Posted on: May 12, 2016
This forest carnivore conservation assessment summarizes what is known about the biology and ecology of the American marten, fisher, lynx, and wolverine. It is the first step in ascertaining what information we need to develop a scientifically sound strategy for species conservation.

Vulnerability of species to climate change in the Southwest: terrestrial species of the Middle Rio Grande

Publications Posted on: August 02, 2013
We used a vulnerability scoring system to assess the vulnerability of 117 vertebrate species that occur in the Middle Rio Grande Bosque (MRGB) to expected climate change. The purpose of this project was to guide wildlife managers on options and considerations for climate change adaptation. The 117 species occur regularly in the MRGB during the breeding season, winter, or year-round.

Sample sizes and confidence intervals for wildlife population ratios

Publications Posted on: February 05, 2013
One of the most common types of data used in applied wildlife management is the population ratio. These data are used to gauge reproductive success and the effect of selective harvesting of wildlife.

Bird populations in logged and unlogged western larch/Douglas-fir forest in northwestern Montana

Publications Posted on: August 29, 2012
Of 32 species of abundant breeding birds, populations of 10 species differed significantly between small cutting units and adjacent uncut forest. Foliage foragers and tree gleaners were less abundant in cutting units, while flycatching species and ground foragers were more common there. Of nesting guilds, conifer tree nesters were least abundant in cutting units, and ground nesters were more common there.

An assessment of climate change and the vulnerability of wildlife in the Sky Islands of the Southwest

Publications Posted on: March 29, 2012
We evaluated the historical and projected trends in climate and vegetation relevant to the Coronado National Forest in southeast Arizona, USA. We then applied this information in an assessment of the vulnerability of 30 species of terrestrial vertebrates on the Coronado National Forest to the potential effects of future climate change. We used a pilot version of a decision-support tool developed by the U.S.
