Forest goods, services, function and valuesIV. Triad ConceptCurrent LectureSilvicultural MethodsSilvicultural-process of guiding the growth and development of forest Improvement cuts and thinningHarvest/Regeneration Cuts (Even-Aged Methods)Clear-cut (simulating stand replacement event….type?)Seed tree (2 to 10 trees per acre left to cast seed)Shelter wood (prepatory, establishment, removal)Coppice (sprout) methodsUsing natural tendencies of some tree species to sproutAspen and Red MapleCut mature forest and within first growing season-you have regenerationAspen used for writing paperHarvest/Regeneration Cuts (even-Aged Methods)Singe tree selection (sounds good….not tough to do)Small group selection (2-5 trees per group)Patch selection (up to 1 acre and 100 trees)Shelter wood1. Prepatory CutA crown thinning to improve the vigor, resistance to wind damage, seed production, and growth rate of residual stand2. Seed CutThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Creates openings, alters microclimate on the forest floor, generates abundant seed….to establish, yet protect seedlings with the “shelter wood”3. Removal Cut (or leaving “Legacy Trees”)Harvesting the shelter wood to release the even-aged regeneration (now large saplings) and add to the total income of the stand treatment (now very valuable trees)Forest goods, services, function and valuesGoods (Market valued, life sustaining)Wood (…100s of products and uses)Food (game, fish, wild rice, berries, mushrooms, ect)Maple products (cultural heritage)Water (the essential forest product)Recreation (many types, many interests, positive and negative effects)Ecosystem services (the greatest good)Carbon sequestrationClean airWater filtration…subsurface and groundwater flowErosion control…soil and slope stabilityTriad Concept1. RESERVE AREASSpecial places, unique valuesNo silviultre (or salvage logging)Few, if any roadsNatural disturbances shape forest“Wild land”(Preservation)2.
