5.17 sustainable forestry

forestry

using trees for lumber that minimizes damage to ecosystem

selective cutting/strip cutting

only cutting some of the trees in an area (biggest and oldest) to preserve habitat (biodiv) and topsoil

sustabialbel forestry

using human and pack animal labor to minimize soil compaction from machinery

replanting same species being logged

maximizing long-term productivity of land and preserves forest for future gens

selective cutting

removal single trees/specific amt

young seelings grow next to established trees

optimum growth amount shade-tolerant soecies

less erosion, loss of biodiv, etc

logging roads

sus forestry practices

using recycled wood, or reusing w out recycling

wood for chipped/mulch

reforestration: planting trees that have been deforested

selectively removing diseased trees to prevent spread of infection thru entire forest

• removing host of disease

  • decreases density, making spread less liekly

fire suprresion

action of putting out all natural forest fires as soon as they start

leads to more biomass buildup, putting out fires immediately leads to more dry biomass buildup

monitoring instead - lose monitoring can prevent fire damage and worse fires in the future

prescribed burning

dead biomass buildup - fuel for large forest fires, stored nutrients trapped in dead biomass, dead trees = susceptible to disease and pest spread

small, controlled burn - uses up dead biomass preventing larger forest fires later

promotes nutrient recycling - nutrients in dead biomass are recycled to new growth
