• System


  set of interrelated activities that work harmoniously to achieve a certain objective.
• Equilibrium, Unique, Boundary, Hierarchy, Dynamic,


  Characteristics of a System
• Systems Concepts

  Everything is related to Everything else
• Forest Organization


  refers to the administrative mechanism by which forest policies and management strategies are implemented. This also refers to the physical and administrative structure and subdivision of the forest.
• Forest Structure


  Pertains to the amount, composition, and distribution of the biotic components of the forest.
• Forest Growth and Yield


  Focus on the productivity of the forest area and as indicators of forest site quality.
• Growth


  Collective rate of change in the volume and size of various organisms over time.
• Yield


  The amount of available forest products that maybe harvested or extracted at a given time.
• Forest Valuation


  the process of determining the financial and/or economic worth of forest resources.
• Forest Regulation


  Aspect of forest management that includes all activities that intend to prevent forest destruction
• Forest Utilization and Conservation


  Producing maximum economic returns and providing a healthy forest ecosystem for the benefit of present and future generations.
• Forest Management Practices


  Adaptive to local forest conditions and can address the needs and constraints of forest managers.
• Stand Stocking


  A qualitative indicator of the distribution of trees in the stand.
• Stand Density


  A quantitative indicator of the distribution of trees in the stand.
• Accretion


  Components of growth that pertains to increase due to development
• Ingrowth


  Component of Growth that pertains to increase due to regeneration.
• Harvest


  Component of Growth that pertains to decrease due to utilization.
• Mortality


  Component of growth that pertains to decrease due to death and decay
• Provisioning Services


  are the materials benefits people get from ecosystem (e.g. food, waters, wood, fuels, etc)
• Regulating Service

  benefits obtained from regulation of ecosystem processes (e.g. air quality, soil fertility, control of floods)
• Supporting Services


  Necessary for the production of all other ecosystem services
• Cultural Services


  are non material, benefits people gain from ecosystem (e.g cultural identity, spiritual well being)
• Diameter and Height


  Independent variables that are commonly used to determine values of tree volume
• Tree Volume

  Dependent Variable in Growth and Yield
• Forest Biomass


  Measure of Productivity
• Aboveground biomass, belowground biomass, necromass, soil carbon

  4 Carbon Pools
• What affects the changes in biomass density?

  Silviculture, harvesting, degradation and natural impacts.
