Gypsy moth spraying has begun on over 200,000 acres of state land

Gypsy moth spraying has begun on over 200,000 acres of state land Updated 10:28 AM; Facebook Share Aerial spraying of woodlands against impending outbreaks of the gypsy moth has begun across Pennsylvania. A total of 203,569 acres at 146 sites will be sprayed through an effort led by the Bureau of Forestry in the Department of Conservation and Natural Resources. Those sites will include 9 state forests, 9 state parks, 25 state game lands and sections of the Allegheny National Forest in 19 counties. “As the insects emerge and begin feeding, the suppression effort will begin in early May,” said Cindy Adams Dunn, DCNR secretary. “Our recent cool, wet springs had emerged as an enemy of the gypsy moth in years past, but populations have climbed in some areas to a point where aerial spraying is needed to keep this invasive pest in check and protect the trees from defoliation.”

Spruce Beetle Outbreak Continues To Ravage Southcentral Alaska

Southcentral Alaska continues to see impacts from an ongoing spruce beetle outbreak that has affected more than 1.1 million acres across the region, according to the Alaska Division of Natural Resources – Division of Forestry. While the outbreak has subsided in some areas, many areas continue to experience steady or increasing beetle activity.   Spruce beetles, which are native to Alaska’s forests, feed and reproduce in spruce trees. All native spruce species and most ornamental species of spruce are suitable hosts for spruce beetle. Jessie Moan, Entomologist with the U.S. Forest Service, “ Spruce beetles become active with warmer spring temperatures. Adult beetles typically start to emerge from their host trees once temperatures reach around 60 degrees.”

Drought causing juniper die-off in central and northern Arizona

The U.S. Forest Service is investigating a significant die-off of juniper trees across much of central and northern Arizona. On the Prescott and Kaibab National Forests approximately 50,000 to 100,000 acres of junipers have been affected in the area between Paulden and Ash Fork along Highway 89 and I-40. Mortality has also been noted north of Williams along Highway 64. Most affected trees are shaggy bark juniper species, including Utah juniper and one-seed juniper. Mortality is varied, with most areas showing die-off of 5-30% of trees, with some larger pockets of dead junipers ranging from 1 to 15 acres. In addition, forest officials have been noting mortality of individual and small patches of alligator juniper in the higher elevation upland areas surrounding the City of Prescott.
