      For example, a recent study in lodgepole pine stands of the Canadian Rockies (Alberta) reconstructed fire history and stand dynamics by cross-dating fire scars with tree age distributions (Amoroso et al. ), yielding evidence that ties the occurrence of low- to moderate-severity fires to the emergence of even-age cohorts and to the formation Cited by: 7.

At least once a year the mountain pine beetle searches for lodgepole pines that provide a suitable habitat for a new brood. After attacking females feed, they produce an attractant pheromone that causes beetles to aggregate and, during outbreaks, to usually mass attack the “focus” tree.

Near the completion of mass attack, incoming beetles are repelled and initiate attacks on adjacent Cited by: In the absence of wildfire for much of the 20th century in our study area, the MPB has played a significant role in directing stand dynamics in lodgepole pine stands.

Stand-replacing fires initiated even-aged seral lodgepole pine stands; while subsequent multiple MPB disturbances have transformed stands into forests with multi-stories and multiple age cohorts, initiated by repeated canopy by: Drawing upon a wealth of past research and results, this book provides a comprehensive summary of state-of-the-art methods for empirical modeling of forest trees and stands.

Using dendroecology and forest measurements we reconstructed the stand processes of stand initiation, stand disturbances, tree mortality, and regeneration, and explained the current stand structure and the potential MPB impacts in selected stands. Our results indicate that stand-replacing fires initiated even-aged seral lodgepole pine stands in this by: lodgepole pine stand dynamics and discuss variable-retention harvesting as a silvicultural option for lodgepole pine.

The mountain pine beetle (Dendroctonus ponderosae Hopkins) (MPB) has infested and killed millions of hectares of lodgepole pine (Pinus contorta var.

It is now spreading out of its native range into the Canadian boreal forest, with unknown social, economic and ecological by: Hard pine rusts can have a large influence on the productivity of juvenile lodgepole pine stands.

Because of the devastation in mature and oldgrowth stands due to the mountain pine beetle epidemic, much greater emphasis and reliance will be placed on second growth stands to. The adaptations of lodgepole pine to severe, stand-replacement fire–in particular its serotinous cones–have long been acknowledged.

Less well-known is that lodgepole pine forests also burn in low- to mixed-severity fire, resulting in patchy and variable patterns across the landscape. Get this from a library. Effects of thinning on temperature dynamics and mountain pine beetle activity in a lodgepole pine stand.

[Dale L Bartos; Gordon D Booth; Intermountain Research Station (Ogden, Utah)] -- "Temperature measurements were made to better understand the role of microclimate on mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Scolytidae), activity as a result.

Lodgepole pine (Pinus contorta) represents an example of an ecosystem that historically experienced what can be categorized as a mixed fire regime, i.e., infrequent high-intensity stand-replacing fires in conjunction with frequent low-to moderate-intensity surface.

Fire, fuel accumulation, and stand development interact in a complex biological network. Mortality factors, such as mountain pine beetle, suppression mortality, and fire cause fuels Cited by: Furthermore, available data indicate that pure pine stands constitute a minority of the forest area affected by the mountain pine beetle (Dendroctonus ponderosaeem>), and that more than 40% of stands dominated by lodgepole pine (Pinus contorta var.

We examined the dynamics of even-aged lodgepole pine forests in southern British Columbia, which were undergoing this MPB outbreak. Using dendroecology and forest measurements we reconstructed the stand processes of stand initiation, stand disturbances, tree mortality, and regeneration, and explained the current stand structure and the potential MPB impacts in selected stands.

An outbreak of the mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB), currently affecting over million hectares of lodgepole pine forests (Pinus contorta Dougl.) in British Columbia, Canada, is the largest in recorded history.

Goudie () also compared lodgepole pine managed stand yield tables generated by TASS against data and a yield model from Sweden (Elfving, ). He concluded that the appearance of higher productivity in Sweden, relative to B.C., is due largely to the absence of natural, unmanaged stands in Sweden, where lodgepole pine is an introduced exotic.

FVS Models & Event Monitor Files The Forest Vegetation Simulator (FVS) is a family of models used for predicting forest stand dynamics (tree growth, mortality, regeneration, management, disturbance, etc.) throughout the United States. Throughout much of British Columbia, lodgepole pine forms even-aged stands initiated by stand-replacing fires.

Although such dynamics is considered typical for the species, uneven-aged lodgepole pine stands that have historically been maintained by frequent low-intensity surface fires are common in.

ABSTRACT Historically, fire was a primary agent of disturbance in Douglas-fir–lodgepole pine forests of central British Columbia, Canada. The historic fire regime included low-severity, stand-maintaining fires and less frequent, stand-replacing fires. At the stand level, fire intervals ranged from two to 59 years, with median intervals of 13 to 22 years.

mountain pine beetle on lodgepole pine stand dynamics, we know the following: Mountain pine beetle induced mortality Mortality caused by primary mountain pine beetle infestation is highly variable, and is dependent upon stand structure and species composition.

In general. Consequently, stand dynamics of lodgepole pine is a primary factor in the development of beetle epidemics. the diameter-growth relationship and the effects of environmental factors on the beetle population provide the basis for assessing potential tree losses and Author: Walter E Cole and Gene D Amman.o'connor, ben g., "mountain pine beetle induced changes to lodgepole pine forest stand dynamics at lubrecht experimental forest" ().
