“…An exception to this procedure had to be made in order to adequately sample the important riparian habitats. Because of the limited aerial extent and narrow configuration of these habitats, a single transect was placed along the long axis of the largest riparian zone within each study site (Bull and Skovlin 1982, Emmerich and Vohs 1982, Meents et al 1981, Mills et al 1991, Stauffer and Best 1980. Riparian transects followed the course of the drainage bottom in which they occurred and extended for about 1-1.5 km.…”

During 1994, fourteen years after the closure of the Anaconda smelters in southwestern Montana, two seasonal wild ungulate fecal pellet group surveys were conducted along stratified random belt transects within three areas in close proximity to the smelters and at a more distant reference area. Vegetation patterns on the proximal sites had been altered by emissions during the 96 years of continuous smelter operation. The densities of mule deer ( Odocoileus hemionus hemionus) and Shiras moose (.A/ces a/ces shiras) droppings on all of the affected areas were either greater, or no different than on the reference area. Seasonal dropping densities of Rocky Mountain elk (Cervus e/aphus nelsom) on the affected area farthest removed from hUlllall activities, were either significantly greater or no different than on the reference area. On the two affected areas closest to hUlllan activities, elk dropping densities were significantly lower than on the reference area in three of the four comparisons. Thirty-three percent of the ANOV A comparisons of seasonal dropping densities on the affected areas were significantly greater than on the reference area, 50% were not significantly different, and 17% were significantly less. The median horizontal diversity index of land cover types was greater (95% Cl) on the affected areas than on the reference site. The mosaic of seral communities that has developed on the affected areas since closure of the smelter appears to have produced levels of big game use which are comparable to those on the reference area, except where elk arc influenced by hUlllan activities.

Northern goshawk and its prey in the Black Hills: Habitat assessment

The northern goshawk is classified as a Sensitive Species in all USDA Forest Service regions, including on the Black Hills National Forest in western South Dakota and northeastern Wyoming. An assessment was conducted of the quality of northern goshawk nesting and foraging habitat, along with the habitat quality of 22 of the goshawk's prey species. A Delphi (expert panel) evaluation of goshawk and prey habitat in 3,414 watersheds averaging 449 acres (182 ha) in size was completed by wildlife biologists from the Black Hills National Forest. The quality of goshawk nesting and foraging habitat and of prey group habitats was reported individually, then combined for each watershed. The optimum goshawk and prey habitat, totaling 67 watersheds or 34,427 acres (13,932 ha), was distributed throughout the nearly 1.5 million-acre (about 607,000-ha) Black Hills National Forest. Panel members found that the Bear Lodge Mountains, located in northeastern Wyoming, proportionally had the most optimum, high-, and medium-rated habitat. Wildfire, bark beetles, urban encroachment, and timber harvest can negatively affect northern goshawks and their prey's habitat. However, increasing the amount and presence of quaking aspen forests within the Black Hills will most likely improve the habitat of the goshawk by improving the habitat for many of its prey. Using previously articulated conditions as a template in the Forest Vegetation Simulator, we designed an example 100-year silvicultural system to create and maintain forest conditions for the northern goshawk and its prey on the Black Hills Experimental Forest.Keywords: northern goshawk, Accipiter gentilis atricapillus, silviculture, forest structure, bark beetles, ponderosa pine, forest management.

“…Other research in the midwestern United States has shown the importance of grassed waterways [Bryan and Best, 1991], riparian areas [Stauffer and Best, 1980], and fencerows [Best, 1983;Shalaway, 1985], as edge habitats for birds in agricultural landscapes. Trnka et al [1990] found 50 avian species in a windbreak-crop (barley, wheat, corn) system of which seven occurred exclusively in fields and 33 exclusively in windbreaks, leaving 10 species that used both habitat areas.…”

Influences of trees on abundance of natural enemies of insect pests: a review

Abstract. In this article we review the use of natural enemies in crop pest management and describe research needed to better meet information needs for practical applications. Endemic natural enemies (predators and parasites) offer a potential but understudied approach to controlling insect pests in agricultural systems. With the current high interest in environmental stewardship, such an approach has special appeal as a method to reduce the need for pesticides while maintaining agricultural profitability. Habitat for sustaining populations of natural enemies occurs primarily at field edges where crops and edge vegetation meet. Conservation and enhancement of natural enemies might include manipulation of plant species and plant arrangement, particularly at these edges; and consideration of optimum field sizes, number of edges, and management practices in and ncar edges. Blending the benefits of agricultural and forestry (windbreak) systems is one promising approach to field edge management that has additional benefits of wind protection and conservation of desirable wildlife species.
