Insect and Disease Conditions in Bryce Canyon National Park Detected During August 1995
Hansen D. 1997. Insect and Disease Conditions in Bryce Canyon National Park Detected During August 1995. Forest Health Protection. R4-97-06. USDA Forest Service. Ogden, UT
Bryce Canyon National Park personnel were interested in establishing baseline information related to forest health. Forest Health Protection personnel conducted a systematic survey for forest insects, diseases and other abiotic damages throughout the forested areas of the Park and adjacent Dixie National Forest lands in August 1995. The major insect and disease agents found were Douglas-fir dwarf mistletoe, "Arceuthobium douglasii Engelmann"; western spruce budworm, "Choristoneura occidentalis Freeman"; Douglas-fir beetle, "Dendroctonus pseudotsugae Hopkins"; and fir engraver beetle, "Scoyltus ventralis LeConte". The implications of these insects and diseases and their role in prescribed fire management are discussed. Generally, it did not appear that the forest health conditions in Bryce Canyon National Park were much different than the Dixie National Forest lands adjacent to the Park. The potential of future bark beetle outbreaks and the continued spread of dwarf mistletoes, especially Douglas-fir dwarf mistletoe, are two forest health issues which Bryce Canyon National Park personnel can address in developing prescribed burn plans.
