Elk Grove Village Public Works recently initiated an inventory project for village owned trees, generally being all trees located within medians and parkways. Using their GPS equipment and seasonal labor the trees are located and their condition, size, and other useful information related to management of the trees are documented. The village GIS (Geographic Information System) is being used to process the GPS data, track the data collection progress, and evaluate the amount and location of trees in poor condition. The initial goal is to replace ash trees in poor condition with other, healthy trees of another species. Having an inventory of the ash trees will allow for rapid and effective management of Emerald Ash Borer (EAB), an invasive species, if discovered in the village. Other objectives that will derive from this information are removing stumps, replacing trees in poor condition, placement of new plantings, and realizing areas that may require more frequent trimming due to the proximity of power lines.
