Summary
TUCSON, ARIZONA-- In 1988 Congress allowed construction of three telescopes on Mount Graham, a desert "sky island" northeast of here, prompting the U.S. Forest Service to order a long-range study to monitor the population of an endangered subspecies of red squirrel that lives here. The results are now in. But the findings--that the work to date has had "no significant effect" on the rare rodents--have done little to resolve a debate that is expected to heat up again next year when the University of Arizona seeks permission to build four more telescopes.
