Document Summary
Slide 2 forest resources local climate cloud forest frogs like it. Slide 3 forest resources coniferous forest evergreen, needleleef trees straight trunks, branch loss. Broadleaf, nutrient resorption prior to pre-winter leaf fall curved trunk, permanent branches. Weathering forests develop and evolve through time. Dead timber snag sere - successional stages of this process secondary succession product (secondary forest) secondary forests produced to make money. Recovery after distrubence size / age at maturity (sexual) O-layer organic layer (the top black lair) Nutrients silt content sand content clay content. Organic content (humus) really good soil. Prescribed burning an important forest management tool (controlled burn) removes competing plants releases nutrients into the soil improves wildlife forage. Many forest fires are started by arsen. More common in fire-suppressed areas to due litter accumulation. They are the biggest problem on tree farms. Habitat management depends on understanding the niche dimensions of focal species and the successional ecology of their habitatas.
