Book Description
Colorado's forests are at risk to forest health problems and catastrophic fire. Forest areas at high risk to catastrophic fire, commonly referred to as Red Zones, contain 2.4 million acres in the Colorado Front Range and 6.3 million acres Statewide. The increasing frequency, size, and intensity of recent forest fires have prompted large appropriations of Federal funds to reduce fire risk and improve fire protection. Experimental ecological restoration studies using thinning and prescribed fire have been conducted at several locations across the State during the past 5 years to determine if high-risk areas could be treated to improve forest health and reduce the potential for catastrophic fires. These studies established that 80 to 96 percent of the trees removed to improve ecological conditions were between 5 and 11.9 inches in diameter. Some trees 12 inches and larger in diameter had to be removed to properly apply ecological prescriptions and typically comprised 4 to 18 percent of the trees removed. The projects studied had profit margins of 1 percent (Pines Partnership), 6 percent (Mixed Conifer Project), a loss of $78,000 (Chessman Reservoir-Trumbull Project), and required subsidies of $779 per acre (Fox Run) and $679 per acre (Air Force Academy). A search for opportunities to use small diameter trees from these projects was conducted as part of an effort to improve the financial feasibility of forest restoration. A previous study, "Wood Use in Colorado at the Turn of the Century" (Lynch and Mackes 2001), describes in detail the various types and quantities of wood products used in the State and identifies where products came from. Using this study, the authors identified potential products that might be manufactured from small diameter trees removed in restoration thinnings. The potential opportunities for using wood are listed in two categories: (1) existing products, processes, and technology, and (2) new products, processes, and technology. Products are arranged within each category in order of increasing complexity of processing and technology. Estimates of the potential retail market value for each product are presented. Examples of existing product opportunities include Christmas trees, mine props, firewood, posts and poles, rough sawn lumber and timbers, and oriented strandboard. Examples of new products and processes include structural roundwood, biomass energy, and wood pulp. The report concludes that future restoration programs must be designed to provide a consistent supply of raw material to processors. It also recognizes that there is no single product that will utilize all small diameter trees from Red Zone areas. Instead, a stable, diverse wood industry appears to be the most desirable future.

Optimum Timeframes for Detecting Songbird Vocalizations in the Black Hills

Optimum Timeframes for Detecting Songbird Vocalizations in the Black Hills PDF Author: Todd R. Mills
Publisher:
ISBN:
Category : Birdsongs
Languages : en
Pages : 392

Book Description
Birds are indicators of vegetation structure and ecological conditions. The singing activity of birds declines during late-morning periods, which can affect estimates of abundance and conclusions regarding vegetative conditions indexed by birds. Therefore, it is important to quantify periods of bird activity so biologists can plan studies. We determined hourly detections from singing males of 22 nongame bird species in ponderosa pine, quaking aspen, and grassland vegetation types in the Black Hills of South Dakota. Detections of 12 of 22 species differed among 1-hr intervals after sunrise. Detections of yellowrumped warblers, Townsend's solitaires, red-breasted nuthatches, western tanagers, and American robins decreased on count-episodes more than 4 hrs after sunrise. Detections of dusky flycatchers declined on count-episodes more than 3 hrs after sunrise and detections of black-capped chickadees were greatest during the first hour after sunrise and declined afterward. Detections of many other species from songs or calls decreased on count-episodes more than 5 hrs after sunrise. We recommend that bird counts in the Black Hills be completed within 4 hrs after sunrise so estimates of bird abundance are not affected by reduced singing among males.
