“…The logistic regression modeling indicated a high likelihood of infestation with a lodgepole pine basal area as low as 2 m 2 /ha. Studies have suggested that stands thinned to a basal area of 27.5 m 2 /ha in pure lodgepole pine forests exhibit reduced susceptibility to mountain pine beetle (Mata et al, 2003). The resulting logistic model is indicative of the magnitude of the outbreak, where essentially all stands with suitable diameter classes are exhibiting high levels of tree mortality.…”

“…These authors describe a unique relationship that has not been reported elsewhere. Mata et al (2003) determined periodic diameter and basal area growth for lodgepole pine stands thinned to varying growing stock levels (GSL) at five locations in Colorado and Wyoming. In general, diameter growth in thinned plots was significantly greater than untreated controls.…”

“…Results indicated that although MPB prefers ponderosa pine, both species are susceptible to attack and can experience extensive mortality. An examination of tree growth and stand susceptibility to MPB in partial cut lodgepole pine stands in northern Colorado and southern Wyoming suggested a basal area of 27.5 m 2 /ha as a threshold for infestation when trees of suitable size are available [38]. A study conducted in unmanaged stands in Colorado indicated that the probability of lodgepole pine stand infestation increased when basal area was >13.6 m 2 /ha and that higher mortality levels occurred when lodgepole pine basal area was >24.4 m 2 /ha [39].…”

“…In the 1970s and 1980s, a series of plots were established in lodgepole pine stands 60-70 years-old to measure the effect of stand density on tree growth and susceptibility to MPB (Mata et al 2003) [38]. Plots were thinned using the concept of growing stock level (GSL) [38,51]. GSL quantifies the relationship between residual basal area and mean stand diameter but has been infrequently used to characterize stocking.…”

Research Highlights: The biology of mountain pine beetle (MPB), Dendroctonus ponderosae Hopkins, in Colorado’s lodgepole pine forests exhibits similarities and differences to other parts of its range. Brood emergence was not influenced by stand density nor related to tree diameter. The probability of individual tree attack is influenced by stocking and tree size. Findings have implications for understanding MPB as a disturbance agent and for developing management strategies. Background and Objectives: MPB causes extensive tree mortality of lodgepole pine, Pinus contorta Douglas ex Loudon, across the western US and Canada and is probably the most studied bark beetle in North America. However, most of the current knowledge on the biology and ecology of MPB in lodgepole pine comes from the Intermountain Region of the US and western Canada. Little information is available from Colorado. This is the first study addressing effects of stand stocking levels on the biology of MPB and quantifying phloem consumption. In addition, although data are available on the conditions that foster stand infestation, this is the first study estimating the probability of individual tree attack among stands of known different stocking. Materials and Methods: Studies were conducted in managed lodgepole pine stands in Colorado. Unbaited traps were used to monitor MPB flight across stands of different densities. Cages were used to monitor emergence and bark samples to determine attack densities, and phloem consumption in trees growing under different stocking. Beetle collections were used to determine emergence across the growing season. Tree mortality data from plots of different densities were used to examine the probability of individual tree infestation. Results: More beetles were caught flying through higher density stands. More attacks were observed in lower stocking stands but there were no differences in the number of insects emerging nor phloem consumption. There was no relationship between tree size and beetle emergence. Peak flight occurred in early to mid-August and only one peak of beetle emergence occurred. The probability of tree attack was influenced by stand stocking and tree diameter. Conclusions: In general, aspects of the biology of MPB in Colorado exhibit similarities and differences with other regions. The data suggest the need to more closely examine how MPB functions in stands of different stocking and how the distribution of tree sizes influence the probability of infestation and extent of mortality in stands. Biological characteristics of MPB in Colorado need further examination, particularly as climate change continues to manifest. Baseline information will be critical to refine management approaches, and extend the understanding of how MPB contributes to shape forest composition and structure in Colorado.
