Abstract

Infrared overflight film was provided by the Texas Forest Service in September 1976 to aid in post oak mortality studies in the city of College Station, Texas. The film aided Texas A&M University urban forestry ground teams in locating trees under abnormal stress. Probable causes were determined on site. The gathered data indicated that construction related damage and not vascular diseases was the primary contributing factor to dieback and mortality. Recommendations were made to the city to reduce man-related stresses on this sensitive shade tree species. As a result a city forester position was established to design and promote tree policies. Incidental benefits of the tree survey included the adaptation of a grid sampling technique and a coordinate inventory system that can be used for street trees and off-street trees simultaneously.
