Fishlake National Forest officials plan to obliterate 65 miles of "wheel track" roads and treat up to 40,000 acres for control of Mormon crickets and grasshoppers on the Fillmore Ranger District.

Acting Supervisor Ronald K. Tew said many of the roads that will be obliterated happened as a result of cross-country travel, primarily during big game hunts. "These roads and travel routes have become sources of erosion resulting in reduced water quality and loss of top soil."Gates will also be installed on 58 miles of the little-used roads to eliminate travel during wet conditions. The program will involve road-bed ripping, waterbarring, original contour restoration, seeding, fencing and placing signs.

The federal Animal and Plant Health Inspection Service will treat grasshoppers and crickets in Millard County. APHIS has conducted control programs on federal lands in that county for several years since an outbreak of Mormon crickets became serious.
