regulatory role in the fire ecology of lodgepole pine. In the first few years after an outbreak, the dead needles provide a highly combustible source of fine fuels. Later, the standing dead trees provide "fire ladders" that serve to conduct ground fires into the canopy, resulting in the stand-replacing crown fires that favor lodgepole pine.

Research on the response of lodgepole pine (Pinus contorta Dougl. ex Loud.) and ponderosa pine (Pinus ponderosa Dougl. ex Laws.) to fertilization in Oregon has been ongoing since the s (Cochran and othersPowers and others ).

Thinning and fertilization produced an additive growth response in lodgepole pine with the best growth occurring when plots were both thinned and fertilized—diameter growth after three growing seasons increased on average cm with thinning, cm with either N-only or complete fertilization, and cm with thinning and fertilization Cited by: 3.

This additive crop tree growth response to thinning and fertilization has been recorded before in lodgepole pine stands [1, 3, 13]; however, the real story of our study relates to our inability to Author: Richard C Yang. Abstract. This study was designed to test the hypothesis that large-scale pre-commercial thinning (PCT) to various stand densities, at ages 12–14 years, combined with repeated fertilization, would, over a year treatment period, enhance productivity of lodgepole pine (Pinus contorta Dougl.

The impacts of thinning, fertilization and crown position on seasonal growth of current-year shoots and foliage were studied in a year-old loblolly pine (Pinus taeda L.) plantation in the sixth post-treatment year ().

The effects of elevated CO 2 (ambient, +, and + μl l −1) and nitrogen fertilization (0,and kg N ha −1 yr −1 as ammonium sulfate) on C and N accumulations in biomass and soils planted with ponderosa pine (Pinus ponderosa Laws) over a 6-year study period are reported.

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. Many of the forest soils in the Intermountain West are deficient in several nutrients, including nitrogen (N), potassium (K), sulfur (S) and boron (B) and these deficiencies may impact tree resistance to insect attack.

Two potential techniques for manipulating tree resistance are fertilization and thinning. We examined fertilization (both alone and in conjunction with stand thinning).Cited by: 1.

The year research program studied the impacts of pre-commercial thinning (PCT) and fertilization on tree growth, plant diversity, forage production, and ungulate habitat use. Ecological effects of cattle grazing were also studied. Three study areas were located in south-central British Columbia, Canada.

Each study area was comprised of densely stocked stands of young lodgepole pine (Pinus Cited by: 1. The treatments were different levels of nitrogen fertilization: control (no nitrogen) and, and kg/ha. In addition, 28 kg/ha of phosphorus was included with each treatment.

The objective of this study was to examine the response in growth and wood properties to midrotation fertilization in a thinned versus an unthinned stand. Data from a thinning study established in loblolly pine (Pinus taeda) plantations at different locations in the southeastern United States were used to develop response models for basal area and survival following thinning.

When sawlogs or multiple products are desired, thinnings should be an integral part of southern pine stand management (Bennett ). Under such circumstances, the issues that must be addressed include: 1) The relationship between initial spacing and the need for thinnings, 2) the time to thin (age), 3) the intensity and frequency of thinnings, and 4) the most appropriate method of thinning.

There are quite a few diseases and pests associated with lodgepole pine, which is perhaps why its rarely planted as a landscape tree. Comdra blister rust kills young pines and causes depressed growth by killing the crowns of Pinus contorta and Pinus ponderosa (Ponderosa pine).

Symptoms are 'spindle-shaped' swollen areas or galls on branches. Heavily thinned lodgepole pine stands developed structural attributes such as large diameter trees, large crowns, and structurally diverse vegetative understories. Forest floor small‐mammal communities reflected the compositional and structural diversity of these managed stands.
