The Maine Department of Conservation – Forest Service has a free-for-download publication that recommends best practices for protecting water quality in forests.
The manual was produced in 2004, but remains relevant to current logging and roading practices. The lead author was Morten Moesswilde (Main Forest Service) and the editor was Alison Truesdale (Landforms). The document is well laid out and makes good use of images and sketches. It is divided into four sections covering the following aspects:
Section 1: Introduction – This section describes what the handbook is to be used for and how to use the handbook. Water movement is discussed and how logging affects water quality.
Section 2: Fundamental Best Management Practices (BMP) – The basic principles of water quality BMP’s are presented. These include pre-harvest planning, anticipating site conditions, controlling water flow and stabilising exposed soil. Filter areas and stabilisation are discussed as key issues.
Section 3: BMP’s for every stage of the harvest – BMP’s for specific stages of the logging operation are included under the headings of stream crossings, wetland crossings, log truck roads, log landings, trails and harvesting, and hazardous materials. The planning, constructing, maintaining and closing out for each stage is covered. Key focus areas in the section are fish passage, how to size and install bridges and culverts, controlling water and water diversion.
Section 4: For more information – This brief section provides a list of sources of technical assistance and references.
