Abstract
A statewide survey of air pollution damage to vegetation was initiated to determine the impact of the problem in Pennsylvania. The body of information presented in this paper is directed to those individuals concerned with economic assessment of vegetation damage. Extension Service personnel, nursery inspectors, and service foresters were enlisted to provide the specialized manpower needed for complete coverage of the State. A 3-day short course was held to acquaint participants with sources of air pollution, dispersion, diagnosis, recognition of symptoms, and methods of assessing damage. An illustrated handbook of typical damage and guidelines in diagnosing injury was prepared and distributed to all participants. A postdoctoral scholar in plant pathology was appointed to investigate each report. Ninety-two cases of suspected pollution damage were reported from 28 counties. Air pollution damage was confirmed in 60 of the cases. Estimates of damage were based on crop value and production costs at the time of damage. These were classified as direct losses. Profit losses, losses resulting from crop substitution, and relocation costs were classified as indirect losses. Monthly progress reports and a comprehensive summary of findings were prepared and distributed to all personnel and agencies involved in the survey. Upon completion of field activities, county agents were requested to evaluate training and survey methods, field investigations, and communication procedures. Results of the survey indicate that acute fumigations are likely to be reported under this system because these are more likely to be brought to the attention of county agents. Chronic fumigations resulting in minor damage are not likely to be noticed.
