Data collected for a habitat monitoring program must be managed and stored to be accessible for current and future use inside and outside the Forest Service. Information maintenance and dissemination are important to the Forest Service; they are part of the U.S. Department of Agriculture (USDA) guidelines for information quality (USDA 2002) under the Data Quality Act of 2001. These guidelines state that USDA agencies and offices will treat information quality as integral to every step in their development of information, including creation, collection, maintenance, and dissemination (USDA...

Information about status and trend of wildlife habitat is important for the U.S. Department of Agriculture, Forest Service to accomplish its mission and meet its legal requirements. As the steward of 193 million acres (ac) of Federal land, the Forest Service needs to evaluate the status of wildlife habitat and how it compares with desired conditions. Habitat monitoring programs provide information to meet the needs of the agency while fostering use of standardized, integrated approaches to produce robust knowledge. This technical guide provides current, scientifically credible, and...

The success of habitat monitoring programs depends, to a large extent, on carefully selecting key habitat attributes to monitor. The challenge of choosing a limited but sufficient set of attributes will differ depending on the objectives of the monitoring program. In some circumstances, such as managing National Forest System lands for threatened and endangered species, habitat monitoring may focus on tracking habitat for one or a few emphasis species. In other settings, such as monitoring the effects of broad-scale land management plans, habitat monitoring may need to address many...

This chapter provides guidance for designing a habitat monitoring program so that it will meet the monitoring objective, will be repeatable, and will adequately represent habitat within the spatial extent of interest. Although a number of excellent resources are available for planning and designing a monitoring program for wildlife populations (e.g., Busch and Trexler 2003, McComb et al. 2010, Thompson et al. 1998, Vesely et al. 2006), little guidance exists for creating a monitoring design for habitat. One could argue that the huge body of literature on vegetation sampling is useful for...

Vegetation composition and structure are key components of wildlife habitat (Mc- Comb et al. 2010, Morrison et al. 2006) and are, therefore, essential components of all wildlife habitat monitoring. The objectives of this chapter are to describe common habitat attributes derived from vegetation composition and structure and to provide guidance for obtaining and using existing and new vegetation data to monitor wildlife habitat. We begin this chapter by addressing key concepts relevant to monitoring vegetation. Next, we describe each of the common habitat attributes associated with vegetation...

Development owing to population increases over the last 30 years has greatly affected forested lands in the United States. To assess and compare increases in development, we counted changes in the number of structures on a systematic grid of photointerpreted points around public forest land in Washington and Oregon. Areas bordering public forest land are showing substantial increases in development, with the number of structures on private lands near almost all types of public forest more than doubling between the 1970s and 2000s. Lands bordering Washington’s Department of Natural Resources...

Dams and impoundments, both large and small, affect downstream physicochemical characteristics and up- and downstream biotic communities. I tested whether small dams and their impoundments altered downstream crayfish assemblages in northern Mississippi. I sampled crayfish and measured physicochemical variables at 4 sites downstream of impoundments (outlet sites) and 4 sites not influenced by impoundments (undammed sites) in August, September, and November 2004. In November 2010, I sampled 7 undammed, 6 outlet, and 3 intermediate sites (influenced by beaver activity or ,1 km downstream of...

Changes in climate and the introduction of invasive species are two major stressors to amphibians, although little is known about the interaction between these two factors with regard to impacts on amphibians. We focused our study on an invasive tree species, the Chinese tallow (Triadica sebifera), that annually sheds its leaves and produces leaf litter that is known to negatively impact aquatic amphibian survival. The purpose of our research was to determine whether the timing of leaf fall from Chinese tallow and the timing of amphibian breeding (determined by weather) influence survival...

Introduced fish reduce the abundance and diversity of native aquatic fauna, but the effect can be reduced in complex habitats. We manipulated fish populations in forested mountain lakes to determine whether or not fish affected benthic macroinvertebrate composition across lakes with differing habitat complexity. We compared abundance, biomass, body-length, and community structure of benthic macroinvertebrates from 16 lakes with three treatments (fish stocked, suspended stocking, fish removed) and unstocked fishless “controls.” Over four years, we assessed the relative importance of fish...
