FRM 121 TIMBER MARCO REYES HARVESTING TIMBER RESOURCE INVENTORY - provide values for the birth, maturation, and death parameters for the healthy forest dynamics. Requires information on productivity of the growing stock of trees (species composition, tree size distribution, the quantity of the growing stock, tree volume increment and size classes) This information are necessary for forest management planning This scale of forest resource inventory depends mostly in the size of the forest area. Size of Forest Area- influence the budget for inventory The periodicity of forest inventory depends on the purpose of inventory and the management intensity of the forest Example What is the Area Sample of the given data? ? Example What is the Area Sample of the given data? Example What is the Number of Plots of the given data? ? Example What is the Number of Plots of the given data? 3. Given: Ap = 5m radius SI = 10% Af = 30ha Np = ? Types of circular plot Types of circular plot
