Comparison of Erosion Reduction Between Wood Strands and Agricultural Straw

May 15, 2003 June 8, 2020 / Erosion Control, Forest Concepts Research & Development, Publications

Abstract Agricultural straw is widely used as an erosion mitigation measure on disturbed soils. It has several drawbacks, however, which include increasing intrinsic value, increasing transportation costs, weed source, pesticide residues, and dust. An alternative is wood strands manufactured from small diameter timber or low-value veneer. A study to determine the efficacy of wood strands …

Functional Requirements and Design Parameters for Restocking Coarse Woody Features in Restored and Enhanced Wetlands

March 27, 2003 June 8, 2020 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Abstract For many years landowners, biologists, engineers and others removed large woody materials such as logs, rootwads and stumps from wetlands, floodplains, and streams of the western United States and Canada. By the early 1970’s scientists and engineers began to recognize the critical roles that wood plays in the life cycle of fish, amphibian, small …

Rural Economic Development through Integrated Smallwood Forest Products Centers

July 31, 2002 June 8, 2020 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Abstract Forest Concepts led the development of a conceptual plan for a smallwood manufacturing center. The Cascade Forest Resources Center (CFRC) is envisioned to be a forest products business park housing 7-10 businesses on a common site. Businesses would include both natural resource service providers and manufacturers. Manufacturers would link to a common woodyard and …

Design and Application of Manufactured All-wood Hillslope Erosion Control Structures

July 31, 2002 June 15, 2020 / Erosion Control, Forest Concepts Research & Development, Publications, WoodStraw

Abstract The FlowCheck™ hillslope erosion control structure was developed to make it easier to accomplish erosion control on burned-over lands, graded slopes and other disturbed areas. The scientific basis for sediment storage behind wood hillslope structures was developed by the U.S. Forest Service Rocky Mountain Research Station. Forest Concepts, LLC combined the best available science …

Technical Products from Small Diameter Timber for Habitat Enhancement and Watershed Restoration

March 26, 2002 June 8, 2020 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Abstract An under-appreciated outlet for small diameter roundwood is in watershed restoration, environmental, and habitat enhancement programs. Over $2 billion is spent in North America on habitat enhancement and watershed restoration each year. Of that amount, our estimate is that approximately $300 million is spent on materials that could be made from small diameter timber. …

Technical Background: Engineered Log Jams

December 31, 2001 June 8, 2020 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Introduction Depletion and loss of functional large woody debris from streams and rivers of the Pacific Northwest is identified as a contributor to the decline in salmonid populations. Salmon, bull trout, steelhead and other fish are dependent on large woody debris (LWD) and channel morphology resulting from the presence of LWD for many of their …

Application and Functional Performance of Engineered LWD

October 15, 2000 June 8, 2020 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Abstract An engineered large woody debris structure has been designed and developed for use in habitat and watershed restoration projects. The structure was designed according to the Appreciative Design method to accommodate readily available wood materials, low-tech manufacturing methods, and volunteer-based installation. Technical features include a high organic surface area, structural integrity in an all-wood …

Near-surface and Subsurface Sensing and Mapping for Site-Specific Operational Decisions: Scoping Paper

June 1, 2000 June 8, 2020 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Introduction Operational practice of precision forestry enables improved forest industry competitiveness and heightened environmental performance. The present study explores precision forestry concepts and technologies in the context of forestry, forest management and silviculture. This paper looks primarily at the case of plantation forestry. Many of the concepts and details of precision forestry apply to short-rotation …

Recasting Industrial Problems for Use in an Academic Setting

July 16, 1998 June 8, 2020 / Forest Concepts Research & Development, Publications, Siskin Ridge Roundwood

Abstract Most industrial problems must be recast for use in undergraduate courses. Recasting often includes problem simplification and adaptation to the educational objectives of the course. Requirements for disclosure of proprietary or trade secret information must be avoided. A number of examples are provided in the fields of forest, agricultural and horticultural engineering. About the …
