In the mountainous Appalachian regions of Maryland and West Virginia commercial Christmas tree growers have been experiencing increasing air pollution injury in their plantations, especially to pines. Types of injuries included chlorosis and necrotic spotting of needles, as well as loss of needles and tree buds. Chronic needle injury generally follows long-term, low-level exposure to the pollutants. Damaged trees have been discolored and misshapened, causing unmarketable and less valuable Christmas trees. Cumulative effects cause stunted, sickly trees, and in time, these weakened trees become vulnerable to insects, diseases and related problems. The effects of oxidants (ozone and peroxyacetylnitrate), fluorides and SO/sub 2/ are discussed.
