Summarizes and consolidates ecological and silvicultural knowledge of lodgepole pine forests, particularly pertaining to regeneration of stands.

Describes the timber source, autecology, and synecology of Rocky Mountain lodgepole pine, including discussions of injurious agents. Discusses factors affecting both natural and artifical regeneration and makes recommendations for. Differences in stand structure among climax lodgepole pine stands in the Rocky Mountains, Sierra Nevada, and south central Oregon were related to disturbance type, frequency, and intensity.

Ponderosa pine occurs in pure stands or may be mixed with lodgepole pine, grand fir, Douglas-fir, western larch, western white pine, incense-cedar, white fir and quaking aspen.

Along the way, Oliver stops to point out patches of natural regeneration of lodgepole pine and new plantations of ponderosa pine. At other stops, it's hard to see many new trees at all.

Differences in stand structure among climax lodgepole pine stands in the Rocky Mountains, Sierra Nevada, and south central Oregon were related to disturbance type, frequency, and intensity. Successful lodgepole pine reproduction was limited by soil moisture and partly by microclimate.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): clearcut harvested, natural lodgepole pine germinants were present at a density of 13 –32 /ha.

A further – germinants/ha were counted the second year after harvesting, but there was no new germination in the three years following. Germination appeared to be heaviest on forest floor material that had. studies with ponderosa pine. Guidelines for thinning lodgepole pines Many lodgepole pine and pon- derosa pine stands, especially in south-central Oregon, are unmanaged and could benefit from thinning.

south-central Oregon lodgepolepine forests: Surface fuel loads changed dramatically between the standing snag and the regeneration stages Lodgepolepine remained dominant, and canopy bulk density was low throughout the chronosequence Time-since-last-MPB mortality event defines the structure of.

A commitment to natural regeneration is a commitment to forgo the benefits of planting genetically improved stock (Streeby ). SEED SUPPLY Production Some seeds are produced nearly every year on nearly every site, but the timing of large seed crops is variable (Table ).

Periods range from 1 year for lodgepole pine seed to intervals of 2. Lodgepole pine was absent from many upper subalpine plots. Objective of the harvest/burn treatment was to develop silvicultural and fire treatments that promote natural whitebark pine regeneration by creating burned openings for Bark beetle infestations of lodgepole pine following a fire in south central Oregon.

Zeitschrift fur. MPB epidemics has focused on the seral lodgepole pine forests of the Intermountain West (e.g., Page and Jenkins ; Klutsch et al. ; Pelz and Smith ).

In con-trast to most other lodgepole pine forests, the Pinus con-torta var. murrayana zone of south-central Oregon is a unique setting because lodgepole pine is an edaphic and. The group shelterwood fostered lodgepole pine regeneration in the cut corridors while maintaining lodgepole pine in the overstory in the leave patches.

This treatment demonstrated that fire does not spread well in lodgepole under typical prescribed fire burning conditions without some type of prior mechanical treatment. With careful marking, it. 1. Introduction. Ponderosa and lodgepole pine forests are dominant ecosystems of western North America (Critchfield and Elbert,Burns and Honkala, ) and provide important ecosystem services including the support of ecological plant and animal diversity, water quality, biogeochemical cycling, and carbon storage (Turner et al.,Wu and Kim,Hurteau et al.

Great comparison, except lodgepole doesn't plug up your chimney the way fast food plugs up your arteries. I've made a few posts about the virtues of Lodgepole pine a few times myself.

I've come to the realization that it's the most reliable, easiest to access and process firewood, in my area. Lodgepole Pine Tree Facts. Forests of lodgepole pines (Pinus contorta Dougl) cover up to 50 million acres in the western regions of North America.

So-called because Native Americans used the. The fire left little on the forest floor to help reseeding, Gardner said. The stand in the Waldo Lake area, which consisted mostly of lodgepole pine, mountain hemlock and true firs, is battling.

Lodgepole pine can grow well on a wide range of land forms including meadows, gentle slopes, and basins or steep and rocky slopes and ridges. It grows better on moister east and north facing slopes than on dry south or west facing slopes. Regeneration.

Lodgepole pine is a prolific, reliable seed producer. Interactions between fire, fungi, bark beetles and lodgepole pines growing on the pumice plateau of central Oregon are described. Mountain pine beetle (Dendroctonus ponderosae) outbreaks occur mainly in forests that are 80– years old with a mean diameter of about 25 cm and weakened by a fungus, Phaeolus schweinitzii.

The outbreak subsides after most of the large diameter trees are killed. Many trees have evolved fire-resistant bark, like ponderosa pine or eucalyptus; others, like the giant sequoia or lodgepole pine in Yellowstone National Park, require fire to open their waxy cones and release seeds, in a process known as serotiny.

Fire also acts as a natural disinfectant, incinerating diseased plants and removing them from the. Lodgepole pine forests cover slightly more than million acres in Colorado or approximately 7 percent of the state’s forested lands. Lodgepole pine (Pinus contorta) is a familiar species in the montane and subalpine forests of Colorado’s northern Rocky Mountains between 8, feet in elevation.

In lodgepole pine forests of eastern Oregon and Washington, although dwarf mistletoe was undoubtedly severe in some presettlement forests, it is now more widely distributed and carrying over between stands now partially replaced by mountain pine beetle rather than more completely replaced by fire [8].

This chapter provides an overview regarding the lodgepole pine (Pinus contorta Douglas ex Loudon) from the perspective of its ecological demands and the possibilities of its silvicultural utilization in Central European conditions.
