Show BARK BEETLES MENACE GRAND CANYON FOREST - . . . : I, Ogden, Utah, October 9, 1922. Ravages of the bark bettle, which , threaten the destruction of the yellow yel-low pine forests about the grand Canyon, have been temporarily 'checked, announces R. H. Rutlldge. District Forester, Forest Service, U. S. Department of Agriculture. i Two thousand trees within the Granjl Canyon National Park and nearly 4,000 on the Kaibab National Forest have been felled and peeled as a preventative measure against the spread of this destructive insect. ; At the request of the National Park Service and the Forest Service, 'field agents were sent b"y the Bureau of Entomology last summer to examine ex-amine large patches of "red top" trees pn both sides of the grand canyon can-yon Highway, running' north from the Park through the Kaibab National Nation-al Forest. The agents reported 'that the trees were infested with the Black Hills hark beetle and advised Uhat immediate measures be taken 'to cut ail infected trees and peel the 'bark In order to destroy the eggs and larvae of the insect, which are found between the inner and outer , bark. . A total of $9,000 was spent in cutting cut-ting 6,000 of the larger and more heavily infested trees. It is estimated that by this method ,i50 and 60 per cent of the Insects were killed within the .patches thus . treated. This, it is said, will check the spread of the beetles temporarily, but an equal amount must be spent next spring in order to effectively prevent further depredations. |
