European Stars And Stripes (Newspaper) - August 2, 1988, Darmstadt, Hesse                                Tuesday August 2, 1988 the stars and stripes Page 7 Forest fires part of nature s Cycle Washington a Forest fires even the big ones that hit Yellowstone National Park last week Are an essential part of nature s Cycle of death and renewal. Humans unwittingly rearranged a lot of nature s Handiwork before realizing that. We almost lost the loblolly Pine in the Southeast in the 1920s and 1930s because of the insistence of the for est service in suppressing All fires said Gene Wood a wildlife ecologists at Auburn Ala University. Such a no fire policy lets Hardwood species get established and once established the hardwoods can out compete the Pine Wood said. Lightning or indians who set fires for Hunting or farming would always Start enough fires to keep hard Woods Down he said. Though specifics differ according to soils weather and species fire has been far More important in Forest evolution in the arid West than elsewhere natural fires caused by lightning Are usually Small. Without harming Trees very much they prevent litter from leaves dead limbs twigs and other organic mat Ter from building up. Contrib use of death renewal in Many Parks fire recycles the nutrients and you get a diversity of wildlife species said Jim Gillette Deputy regional director of the fish and wildlife service in Boston. His Agency probably sets 400 fires a year ranging from 100 acres to 2,000, acres on its 443 refuges and other installations. In some ecosystems rigid suppression of natural fires Means enormous amounts of fuel can accumulate on the Forest floor. When the inevitable lightning does strike the fire can be impossible to suppress and More destructive than anything that would have happened naturally. In some areas like the great lakes Damp soils kept fires from getting started on the Forest floor. When a fire would Start in a dry Cycle maybe once a Century it would spread to the crowns and sweep All before it. You have selection for species that can recover said Wood. It takes a Long Long  a fire in California Sequoia tree crowns in 1955, where the floor normally would Burn every decade or so prompted a re examination of the fight every fire policy by the National Park service. By 1968 the service was igniting the undercover in the Sequoia National Park trying to return the Forest to its natural state. In 1972 it adopted what has been called a let Burn policy. We were almost killing the Trees with  before that said chief Ranger Walt Dabney. The new policy had been Long germinating from research dating to the 1930s, said Wood some of whose research helped spread the gospel. A lot of the old foresters and game wardens could have tarred and feathered me he said. Strictly speaking let Burn is a Misnomer. Dabney said the policy always contemplated Casc by Case Deci Sions. Fires that threaten structures Are always fought. Fires that might be left alone would be fought if they could spread outside the Park into commercial Tim Bering for example.

Lack of control on Job linked to heart risk new York a men whose jobs Combine High psychological demands and Little control Over their work face two to three times the risk of heart attack that other male workers do a new study suggests. Cooks waiters computer operators Gas station attendants and some Assem Bly line workers were among the High risk jobs found in the analysis of nearly 5,000 men. But employers May be Able to redesign High risk jobs to lower heart attack risk and improve productivity said Robert Karasek associate professor in the Industrial and systems engineering depart ment at the University of Southern Cali fornia. Karasek reports the study s findings in the August Issue of the american journal of Public health along with co authors from Sweden the state University of new York at Stony Brook Cornell University medical school and Columbia University. The study focused on Job Strain which results from having too Little control Over one s work to deaf satisfactorily with its psychological demands. Those demands included having to work quickly with heavy workloads. Executive and professional jobs were not considered High Strain because they include a lot of control Karasek said. The study was based on past heart at tacks involving men in two Federal sur Veys. Too few women with heart attacks appeared in those surveys for a meaning Ful analysis Karasek said. To assess Job characteristics for All 4,833 men researchers used Federal stud ies of the conditions faced by workers of various jobs. Measurements for Job traits such As control Over the work were computed for 221 occupations. The study listed two sets of findings one from each of the Federal surveys men whose jobs put them in the top 20 percent for Job Strain had 2.48 times and 3.28 times the risk of heart attack of the other workers. The Compa Rison Usk into account Ages which Karasek said was the most important influence on heart attack risk but ignored other risk factors like smoking. Men in the top 10 percent for Job Strain ran 3.8 and 4.79 times the heart attack risk of men in the lowest 10 per cent. Jobs in the top 10 percent included Cashiers and waiters while those in the Bottom 10 percent included foresters natural scientists and civil engineers. This comparison took into account a list of heart attack risk factors age race cigarette use education blood pressure and cholesterol Levels. Job Strain appeared to account for Between one fourth and one third of heart attacks in the two surveys. This analysis accounted Only for age but Karasek said the results were similar when the other risk factors were also consid ered. The study does not prove that Job Strain raises the risk of heart attacks Karasek said but the idea is supported by other research
