They devised a Landscape Assessment System -- a low-flying airplane using "geo-tagged oblique aerial photography to assess the cumulative mortality at the sub-watershed level." They found the beetles have a far greater impact than the U.S. Fish and Wildlife Service had estimated (for details, see sidebar about the “ragtag team” at left).
