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.

Multi-scale niche modeling of three sympatric felids of conservation importance in central Iran

Publications Posted on: September 16, 2019
Carnivores in the central Iranian plateau have experienced considerable declines in their populations during the last century. Ecological niche models can inform conservation efforts aimed at increasing the suitability of carnivore habitat by providing valuable information on the scale-dependent relationships between species and their environment.

Species-specific differences in detection and occupancy probabilities help drive ability to detect trends in occupancy

Publications Posted on: April 05, 2019
Occupancy-based surveys are increasingly used to monitor wildlife populations because they can be more cost-effective than abundance surveys and because they may track multiple species, simultaneously. The design of these multi-species occupancy surveys affects statistical power to detect trends in occupancy because individual species vary in resource selection, detection probability, and rarity.

Using environmental DNA methods to improve winter surveys for rare carnivores: DNA from snow and improved noninvasive techniques

Publications Posted on: November 29, 2018
The management of rare species is a conservation priority worldwide, but this task is made difficult by detection errors in population surveys. Both false positive (misidentification) and false negative (missed detection) errors are prevalent in surveys for rare species and can affect resulting inferences about their population status or distribution.

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.

Chapter 5: Wolverine

Publications Posted on: May 24, 2007
The wolverine (Gulo gulo) is the largest-bodied terrestrial mustelid. Its distribution is circumpolar; it occupies the tundra, taiga, and forest zones of North America and Eurasia (Wilson 1982). North American wolverines are considered the same species as those in Eurasia. They are usually thought of as creatures of northern wilderness and remote mountain ranges.

Chapter 4: Lynx.

Publications Posted on: May 24, 2007
Three species of wild cats (felids) occur in the temperate forests of North America: the cougar (Fells concolor), bobcat (Lynx rufus), and lynx (Lynx canadensis). The cougar is found in both temperate and tropical forests from the mountains of southern British Columbia to the southern tip of South America, whereas the bobcat and lynx are restricted to the temperate zone of North America.

Chapter 3: Fisher

Publications Posted on: May 24, 2007
The fisher (Martes pennanti) is a medium-size mammalian carnivore and the largest member of the genus Martes (Anderson 1970) of the family Mustelidae in the order Carnivora. The genus Martes includes five or six other extant species. The fisher has the general body build of a stocky weasel and is long, thin, and set low to the ground.

Chapter 2: American marten

Publications Posted on: May 24, 2007
The American marten (Martes americana), also called the marten or American sable, is a carnivorous mammal about the size of a small house cat. Its total length is between 500 and 680 mm and it weighs 500-1400 g as an adult, depending on sex and geography (Buskirk and McDonald 1989; Strickland et al. 1982). The male is 20-40% larger than, but otherwise similar in appearance to, the female.
