Document Summary
Forest development ecological succession: forests develop and evolve through time, primary ecological succession (how ecosystems change through time) Inferior competitors for light: shade tolerant species, able to flourish under a canopy, often dominant during late succession, superior competitor for light, commercially important species (sugar maple, southern magnolia, flowing, seeding and germination habits dogwood) Insect, bird, and mammal pollinators: bird and small mammal seed dispersers. Industrial urban areas in mdcs: human activities, volcanic eruptions. Rnr 1001 notes test 4: acid deposition, ozone, and spm (dust, soot, asbestos, heavy metals, leaf and bark damage, increased susceptibility to pathogens. Sustainable forest management: forest conservation includes maintenance of ecosystem services, ecosystem biodiversity, watershed function, erosion control and soil dynamics, carbon sequestration, biogeochemical cycles, local climate control. Intermediate management: even-aged management, harvest, replanting, harvest of same-age trees, short rotations, lower-quality lumber, maximize economic return asap, produce shade-intolerant species, trees harvested by, shelter-wood cutting, seed-tree cutting.
