BIOGRAPHY OF A RIVER

slope: degree of deviation of a surface from the horizontal, measured in degreesstreamside management zone (SMZ): area left along streams to protect streams from sediment r and otherpollutants, protect streambeds, and provide shade and woody debris for aquatic organismssuspended solids: small particles of solid materials in water that cause cloudiness or turbidityUSGS: United States Geological Surveywater bar: a long mound of dirt constructed across the slope to prevent soil erosion and water pollutionby diverting drainage from a road or skid trail into a filter stripwaters of the state: includes every natural or artificial watercourse, stream, river, wetland, pond,lake, coastal, and ground or surface water wholly or partially in the state, that is not entirelyconfined and retained on the property of a single landownerADVANCE PREPARATIONThe objective of this activity is to introduce the student to forestry BMPs, how they should beprescribed and evaluated, and how some water quality indicators may be affected by loggingpractices.Locate several logging sites in the local area, preferably adjacent to streams. Sites can be in theprocess of being harvested prior to construction activities (land clearing), but a “true” forestryactivity is preferable. A site above and below the logging area along the stream should beidentified. If there is no stream below the logging area, parts of this activity can still be done.Students should be made aware of good conservation practices.PROCEDUREI. Setting the stageA. Put terms on the board and define. Discuss.B. Discuss problems that can be caused by erosion and sedimentation from an improperlylogged area or poorly designed or constructed roads.C. Using the state silviculture BMP manual, identify the BMPs that should be followedon the logged area.3-46
