Book excerpt: Mountain pine beetle populations have been increasing in the Black Hills over the last 3 years. In 1998, 1999, and 2000, aerial surveys have detected a large mountain pine beetle infestation in the Beaver Park area on the Northern Hills Ranger District. Ground surveys found 41.4 trees per acre killed on average over the last 3 years, with approximately 61% of these trees being currently infested. Also, brood sampling continues to indicate that beetle populations are still increasing in the area. Three years ago nearly 70% of the forested land in the Beaver Park area was classified in the moderate to high stand susceptibility categories. Stand susceptibility is being reduced as much of the basal area has been decreased by beetle-caused tree mortality. However, because there has been no treatment, there continues to be epidemic mountain pine beetle populations and associated high levels of tree mortality in the Beaver Park area. In addition to the mountain pine beetle situation in Beaver Park, pockets of beetle-killed trees have been detected from aerial survey in the Bear Mountain and Steamboat Rock areas. Ground surveys in these areas found an average of 8.2 and 7.3 trees per acre killed over the last 3 years, respectively. More than 45% of these trees are currently infested. Brood sampling in both areas suggest beetle populations are increasing. Relatively few currently infested trees were found in the Pactola Lake, Sheridan Lake, and Deerfield Recreation Areas. Strategies for dealing with the mountain pine beetle include: do nothing, silvicultural treatments, sanitation/salvage harvesting, infested tree treatment, and individual tree protection. Although the part of the Beaver Park area that has been classified as roadless is off limit to treatment, a full range of treatments should be considered in the surrounding areas to limit the continued expansion of the mountain pine beetle epidemic in this area. Similarly, a combination of silvicultural treatments and sanitation harvesting or mechanical treatment is recommended for the Bear Mountain and Steamboat Rock areas. Continued sanitation removal of infested trees within the recreation areas is recommended.

Book excerpt: Mountain pine beetle populations have been increasing in the Black Hills over the last 3 years. Over the past few years, aerial surveys have detected a large and expanding mountain pine beetle infestation in the Beaver Park area on the Northern Hills Ranger District. Ground surveys found 37 trees per acre killed on average over the last 3 years, with approximately 53% of these trees being currently infested. Also, brood sampling continues to indicate that beetle populations are still increasing in the area. Four years ago nearly 70% of the forested land in the Beaver Park area was classified in the moderate to high stand hazard categories. Stand hazard is being reduced as beetles have reduced much of the basal area. However, as beetle habitat is lost in areas such as Forbes and Beaver Gulches, the beetles are starting to move out into surrounding forest lands in the area. Places such as Vanocker Canyon, Park Creek, and Elk Creek Canyon are becoming heavily infested with mountain pine beetle. Recommendations for dealing with the mountain pine beetle include: silvicultural treatments, sanitation/salvage harvesting, infested tree treatment and individual tree protection. Aggressive use of silvicultural techniques, both thinning and sanitation, are the recommended actions.

Book excerpt: Ponderosa pine mortality due to mountain pine beetle (MPB) activity has been detected in air and ground surveys of the Black Trout Analysis Area on the South Park District of the Pike-San Isabel National Forests and Comanche and Cimarron National Grasslands. The South Park Ranger District has proposed mechanical and prescribed burn silvicultural treatments on approximately 12,500 acres of National Forest Lands to salvage trees killed, to reduce MPB infestations, to reduce disease impacts and to reduce the potential for crown or high intensity wildfires within designated areas of the Black Trout Analysis Area.‍?Lakewood Service Center-Forest Health Management (LSC-FHM) personnel used aerial survey information and ground surveys to determine stand conditions and the level of beetle infestation in the Black Trout Analysis Area. Ground surveys included strip samples and systematic variable radius (VR) plot samples. Strip samples indicate MPB population trends by comparing the number of trees infested in 2004 and the number of MPB-killed trees in 2003. VR plots record stand density and tree diameter which is used along with available stand exam data to determine stand susceptibility.‍?Results indicate an increasing population trend in 4 of 9 units surveyed and a decreasing trend in 5 of the units where MPB had already killed many trees. Although many stands have already suffered high levels of mortality, there remains a high risk of infestation to all susceptible stands in the proposed treatment areas. Average stand diameters, age, tree density and elevation indicate that stands in the proposed treatment areas are either moderately or highly susceptible to MPB outbreaks.‍?Management actions to address the MPB infestation in the Black Trout Analysis Area are discussed. Sanitation and salvage of beetle infested trees and reducing stand density in the uninfested portions of the proposed treatment areas may help reduce MPB impacts and reduce stand susceptibility to MPB attack.
