“…Provenance, family, and parent-offspring studies A second type of evidence for genetic control of air pollution tolerance came by com¬ paring the air pollution responses of: (a) various populations from across the range of a species and (b) related individuals as compared to nonrelated individuals in 1/2-sib family, full-sib family or parent-offspring trials. Seed source or provenance differences in the response of trees to ozone has been shown for Acer rubrum (Berrang etal., 1986b;Townsend and Dochin¬ ger, 1974), Fraxinus americana and F.pennsylvanica (Karnosky and Steiner, 1981), Pinus strobus (Genys and Heggestad, 1983), and Pinus taeda (Adams et al, 1988;Kress et a!., 1982a,b;Winner et al, 1987), and Populus tremuloides Michx. (Berrang etal., 1986a).…”

At the Tenth Meeting of the US-USSR Joint Committee on Cooperation in the Fieid of Envi¬ ronmental Protection, held in Washington, D.C. in 1986, Dr. Juri Martin and I agreed that our proj¬ ect (Project 02.03-21) should organize a symposium in the United States to commemorate the tenth year of cooperation on this project. The major objectives of the symposium were to acquaint scientists on the two sides with project accomplishments, to promote understanding of the nature of environmental problems that relate to air pollution effects on vegetation on a more global scale, to share research priorities, interests, and methodologies and to plan future research cooperation. It was decided that holding a "traveling" symposium at three different locations would make it possible to expose a greater number of the U.

A thorough review and critical evaluation of field surveys from 1900 to the present of foliar injury to Pinus strobus L. supposedly caused by air pollution was undertaken. Ninety percent of the surveys failed to meet current scientific standards of acceptability. The conduct and peer review of surveys has been poor and the correct injury symptoms have not always been used. Data were obtained for nine that met screening criteria and injury incidence and severity were mapped. Three fourths of the counties in the natural and planted range of eastern white pine have not been scientifically surveyed, so generalizations regarding large-scale spatial patterns of eastern white pine foliar pathological conditions were not possible. However, recent growth and inventory data indicate that growth throughout the natural range regardless of air pollution or other stresses (e.g. blister rust) is excellent, suggesting that regional performance and foliar conditions are unrelated. Sufficient compelling corroborative evidence was found to conclude that a general decline of eastern white pine throughout its range is not a tenable finding.The putative air pollution sensitivity of eastern white pine appears to be based on studies published between 1963 and 1973 on hypersensitive individuals that are no longer being observed in the field. More recent research on eastern white pine has noted a lack of sensitivity and/or high variability of response. The idea that eastern white pine as a species is highly sensitive to air pollution is no longer supported by the available evidence. However, hypersensitive juvenile individuals comprising no more than 8-9% of the total population may still germinate and grow for a brief period of time (because old enough parent trees are still alive) but soon succumb to current levels of ozone and sulfur dioxide in the environment or are suppressed by tolerant neighbors. This phenomenon has been documented anecdotally and is more aptly called tree decline instead of forest decline. An emerging working hypothesis to explain recent reports of unusual eastern white pine tolerance is that sufficient time has elapsed for tree decline to have occurred leading to a gradual elimination of sensitive genotypes from populations.
