Compilation of data on thinning experiment in Douglas fir on McDonald ForestAuthor: Forrest J. Abbott. Survival of planted Douglas-fir seedlings was recorded for 11 years and growth was quantified for 9 years after the last treatment application.
In addition to Douglas-fir, data are presented individually for the two most abundant species (tanoak and snowbrush), for greenleaf manzanita, and for the hardwood tree and shrubs combined.
The Shawnigan Lake Project was established to achieve a better understanding of tree growth processes and develop effective and environmentally acceptable thinning and fertilization practices to increase wood volumes (Crown and Brett, ).It was established in on a year-old Douglas-fir plantation with a site index of 21 m and average stand density of approximately Cited by: 2.
The paper deals with the first results from thinning experiments in the forest stands with both mixed and unmixed Douglas-fir. Douglas-fir reaction, expressed by diameter at the breast height (DBH. 9) This study will examine the impact of thinning and fertilization on parameters of Douglas-fir and lodgepole pine resistance to insect.
Treatment impact on selected pests (mountain pine beetle, pine engraver, Douglas-fir pole beetle and Douglas-fir tussock moth). In –, two-year-old Douglas-fir seedlings were planted at the rate of trees/ha under three levels of site preparation: (1) no treatment, (2) oak thinned by 50%, and (3) oak clearcut.
From toyearling ewes grazed one-half of each of the three thinning treatments for 3–4 weeks each spring. The overstory was still dominated by ponderosa pine 22–23 years later for all treatments, but the smaller size classes were primarily Douglas-fir, suggesting that without future disturbance.
Douglas-fir roots collected from dry, warm Douglas fir habitat types had sugar concentrations of 4% compared to 3% for roots from cool, moist habitat types.
Root samples collected from Douglas-fir habitat types showed tannin concentrations about double those from grand fir or western redcedar habitat types. Intermountain Research Station (Ogden, Utah): Ten-year results of fertilizing grand fir, western hemlock, western larch, and Douglas-fir with nitrogen in northern Idaho / ([Ogden, Utah]: U.S.

In the temperate rainforests of northwestern North America (Franklin and Halpern ), the outcome of this interaction for most of the 20 th century was a management emphasis on wood production (Curtis et al.Haynes et al.
Because of production efficiencies, even-aged, clearcut systems. Re-measurement data over a period of four years from 24 permanent plots were analyzed to determine the effects of three different spacing regimes on growth of uneven-aged interior Douglas-fir (Pseudotsuga menziesii var.
glauca), near Williams Lake, British Columbia. Spacing was carried out during the fall and winter of Growth was analyzed at the stand and individual tree level. The maximum negative effect is the removal of the organic layer in the mature Douglas fir forest.

Seed is produced annually except for "about 1 year in any 4- to 5-year period" .Age at first reproduction is 12 to 15 years (both varieties).

Levels-of-growing-stock cooperative study on Douglas-fir: report no. 02—The Hoskins Study, Public and private agencies are cooperating in a study of eight thinning regimes in young Douglas-fir stands. Regimes differ in the amount of basal area allowed to accrue in growing stock at each successive thinning.
However, seedling-origin Douglas-fir will often outgrow the sprout-origin redwood by about age [17,47]. Hence, young forests often include a large Douglas-fir component that may persist through the first century or longer of even-aged development. Redwood and Douglas-fir will eventually outgrow tanoak and other broadleaved species.
In 2 experiments in southwestern Oregon, and 14year measurements of Douglas-fir growth showed that the mean volume per tree was about and % higher, respectively, when hardwoods and herbaceous vegetation were controlled using herbicides (Hanson ). In addition, the early negative influence of competing vegetation led to significant.
The McDonald's fast-food restaurants certainly provide a useful example of a familiar sociological artifact that can be analyzed to generate a more general and macro level of conceptualization.
Few artifacts and institutions of the contemporary world are as well-known and ubiquitous as McDonald's with its Big Macs, Golden Arches, Ronald McDonald's. Intotal revenues reached USD$ billion. This is a 2% growth from its figure. Based on data for the past six years, the company had the highest growth rate in at 12%.
However, the company experienced a steep decline the following year, with growth rate at only 2%. Table 1. McDonald’s 6 Year Summary (Millions).

Progress 08/15/97 to 08/15/07 Outputs OUTPUTS: The science under this problem area directed two large-scale interdisciplinary studies on the Klamath National Forest and the Lassen National Forest. The unit released version of the CONIFERS growth and yield simulator and conducted a study to expand the range of the simulator to Douglass-fir stands of the Pacific Northwest.
Managers need methods for enhancing the vigor of old-growth forests and for predicting how alternative silvicultural actions affect forest composition, health, and vigor. In addition, managers need tools to forecast development of young conifer stands.
This research provides managers with computer models, and flexible guidelines to protect forest health and sustainability both under existing.

Recent research has shown that common forest management activities have long-term impacts on stream flows. In a paper entitled “Summer stream flow deficits from regenerating Douglas-fir forests in the Pacific Northwest, USA” two researchers from Oregon State y Perry and Julia Jones, analyzed a year record of daily stream flow from eight paired-basin experiments in.

Research Note RM Forests can also be classified more specifically based on the climate and the dominant tree species present, resulting in numerous different forest types (e.g., Ponderosa pine/Douglas-fir forest).
