Forest Inventory and Analysis Program: Trends for Georgia’s Forest Land – 2016 FIA Data Created by: David Dickinson FIA Coordinator for Georgia [email protected] David Dickinson FIA Coordinator Georgia Forestry Commission PO Box 819 Using Evalidator Version 1.8.0.00 found at: https://apps.fs.usda.gov/Evalidator/evalidator.jsp Macon, GA 31202

Forest Inventory and Analysis, Georgia FIA facts and history The Forest Inventory and Analysis (FIA) Program is a cooperative program between the U.S. Forest Service and the states to provide estimates of the condition of the forest and forest trend data A forest inventory was mandated as necessary by the U.S. Congress in the 1930’s in order to provide status updates of the United States’ forest resources The data can: Indicate if forest resources are being managed sustainably Indicate trends such as gains or losses of forest acreage, the species David Dickinson composition of our forest, the age/quantity/quality of the timber FIA Coordinator resources and the health of our forests. Georgia Forestry Commission Data are collected on research plots across the state on public and private PO Box 819 land Macon, GA 31202 Landowners have the opportunity to deny access to their property at any time

Forest Inventory and Analysis, Georgia FIA in Georgia Georgia assumed data collection responsibilities from U.S. Forest Service in 1998 All data are given back to the USFS for compilation/analysis FIA is a 75% federally funded grant with 25% of funds matched by states with 5 year cycles We currently have 12 foresters collecting FIA data across Georgia All foresters on the FIA team in Georgia have degrees in forestry and are tested and certified prior to collecting data in order to maintain data integrity All data, once compiled, is made available to the public at www.fia.fs.fed.us/tools-data and through publications such as Forest Factsheets and this powerpoint on the Georgia Forestry Commission website No individual landowner information from the FIA Plots is made public in order to protect privacy

Forest Inventory and Analysis, Georgia Why is a Forest Inventory Needed? Without a forest inventory there is no scientific source for the trends of our forests – provides consistent metrics over time Without a forest inventory, forestry decisions in our agency, the state government and the federal government are made based on feelings and popular opinion instead of numbers Our numbers give forest industry the necessary information to decide to locate new wood using facilities here in Georgia – new mills new jobs putting Georgians to work FIA gives us the opportunity to correct undesirable forest trends before it is too late FIA data are based on ground measurements and provide a ground truth for satellite imagery tools to test against and improve over time. Nothing replaces boots on the ground.

FIA Plot Layout Each plot on which data are collected is made up of four 24’ radius subplots. Tree measurements are collected on trees 5 inches and greater within this radius. Information on smaller trees is collected within the microplot.

Hex Grid with One Plot per Hex ( 6,000 Acres) One plot is placed randomly within each 6000 acre hex. Each plot is permanent to allow for time 1 to time 2 comparisons of the same trees and any new ones. Each plot is remeasured about once every 5 years.

FIA Data Collected on Each Plot Measurements include: Species Diameter Height Tree Class – is it straight enough? Log Grade Crown Position Live Crown Ratio Location of each tree from plot center using azimuth and distance Invasive exotic plant species, slope, aspect, forest type, stand age, disturbances (fires, insects)/treatments (harvests, planting, natural regeneration)

Georgia’s Forests Final Thoughts Our forests are being managed sustainably Forests benefit all Georgians with a continuous flow of goods and services of traditional forest products Also benefits society with clean air, clean water, wildlife habitat, soil conservation, recreation and aesthetic benefits Remember that 2 out of 3 raindrops in Georgia fall on forestland Planting pines now for the future is what Georgia needs to remain sustainable www.gatrees.org
