I thought, "Now I've heard of everything!" But, there is some logic in taking tree inventory. The information gathered will be used to determine our species diversity, age diversity of the trees, calculate benefits of our urban forest, such as lbs. of carbon sequestered, and the number of gallons of storm water runoff avoided because of the trees, which amounts to more than a million gallons a year. The collected information will also be used to determine where the City can plant more trees in the future.
