Here, through private and federal grants and ongoing assistance from the Bureau of Land Management, officials have trained students to conduct extensive urban tree inventories using GPS and GIS technologies on the school’s 81 hectare wooded campus. A fully-operational GIS laboratory at the school is used by all urban forestry, biology, and chemistry classes. Training includes a three-day teacher workshop on Arcview, a popular GIS software, and student instruction in GPS and tree species identification. Students then receive instruction on how to collect data and use the Piney Woods Tree Inventory System to complete an Urban Ecological Analysis. The urban forestry class meets once a week, alternating sessions between field data collection and computer laboratory data entry. By plotting trees on a map of their campus and then recording information such as tree location, size, and species, students can calculate air pollution removal rates, energy conservation, carbon storage, and sequestration rates for their urban forest. In the process, students learn the value of trees in urban environments, such as reducing air pollution, conserving energy by providing shade to buildings and air conditioning units, reducing erosion, and providing aesthetic improvements.
