Previous studies have documented the extent of air pollution damage to herbaceous plants and crops in NJ but little data exists on effects on woody species. Therefore the authors undertook a 2 yr survey of pollution damage to trees. With the aid of the NJ Cooperative Extension Service, the NJ Dept. of Agriculture, the Nurserymen's Assn., the Christmas Tree Growers Assn., Shadetree Commissions and the NJ Dept. of Environmental Protection, the authors located sites of potential air pollution damage, and made field inspections. They also made test plantings, fumigated selected species and performed tissue analyses. Injury has been observed on many species both from photochemical oxidants and acid gases, primarily HF. Oxidant damage has been observed on white pine throughout the state. Fluoride injury has been recorded on a variety of woody species in a residential area near an oil refinery and in a rural zone around a fiberglass factory. Symptoms were as previously described, however, leaf abscission was observed on deciduous and coniferous species severely injured early in June. By late summer regrowth had begun. Oak, considered resistant to fluoride damage, was severely and extensively damaged. Other problems on evergreens, which are tentatively ascribed to air pollution, continue to be observed. What the authors term winter spot on spruce and pine appears identical in visual and histological development to winter fleck described in California on ponderosa pine.
