An Evaluation of the Density Management Diagram for Coastal Douglas-fir: Author(s) or contact(s): I.R. Cameron Source: Research Branch Subject: Growth and Yield Series: FRDA Report Other details: Published Hardcopy is available. A method of viewing stand density as it relates to volume production and tree size is developed in the form of a simple density management diagram applicable to plantations of coastal Douglas-fir Author: Murray Woods.

Drew and Flewelling (), for example, developed a graphi­ cal density management diagram to determine the potential trade-offs between maximizing average size of individual trees and stand yields.

They suggest that. A density management diagram was constructed using stand inventory data from teak (Tectona grandis L.f) plantations in Western Ghats of peninsular India.

In order to better understand the genetic control of wood density in juvenile Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), and to assess the utility of information on its components for improving the efficiency of selection for overall wood density, wood density components were examined in year-old trees of 60 open-pollinated by: 3.

Douglas-fir in the Rocky Mountains (Hermann and Lavender ; Arno ). In the northern part of its range, IDF is limited by cold, especially growing season frost. In dry ecosystems such as the Interior Douglas-fir zone (IDF) of British Columbia, Douglas-fir is the climax species (Arno ; Hope et al.

Stand density index was present by Reineke () and can be defined as: where SDI is Stand Density index, D q is the quadratic mean diameter.

Quadratic mean diameter is the diameter of. The Coast Douglas-fir is an evergreen conifer native to the coastal regions of western North America. Coast Douglas-fir is a very large tree, the second-tallest in the world. The Coastal Douglas-fir (CDF) is the smallest of the 14 BC ecosystems listed in the Biogeoclimatic Ecosystem Classification system.

It is restricted to low elevations along southeastern Vancouver Island, from Bowser to Victoria, the Gulf Islands south of Cortes Island, and a narrow strip along the Sunshine Coast near Halfmoon Bay. Forest regeneration needs to be applied under the direction of silvicultural prescriptions and the context of silvicultural systems.

Management interventions should be implemented if the current or expected stand conditions are unfavourable for target species to achieve management objectives. To illustrate these concepts, this paper uses coastal Douglas-fir (Pseudotsuga menziesii var.

coastal regions. While Douglas-fir trees are tolerant of a wide range of environ-mental conditions and grow in many parts of the province, many of the other plant species of the coastal Douglas-fir ecosystems are more specifically adapted to the summer droughts and winter rains that characterize this climate.

In total, there are about species. Abstract. Wood nitrogen isotope composition (δ 15 N) provides a potential retrospective evaluation of ecosystem N status but refinement of this index is needed.

We calibrated current wood δ 15 N of Douglas-fir (Pseudotsuga menziesii), an ectomycorrhizal tree species, against a productivity gradient of contrasting coastal forests of southern Vancouver Island (Canada).Cited by: 7.

Curtis' Relative Density is based on the relationship between tree size and the number of trees per acre or hectare. A Measure Useful in Douglas fir Management. The Coastal Douglas-fir zone (CDF) is limited to a small part of southeastern Vancouver Island, several islands in the Gulf of Georgia, and a narrow strip of the adjacent mainland (Figure 15).

It is confined to elevations mostly below m. Climate and plant communities similar to those of the CDF in British Columbia occur in. Stand density has a major potential impact on individual tree size and stand yield [8,9,10].Castedo-Dorado et al.

Forest Ecology and Management Douglas-fir Shrinkage and Dimensional Stability Douglas-fir is an important building timber in North America, particularly in the Pacific north West, where it has a reputation for being naturally dimensionally stable – the ability to “season well in position” and retaining its shape during use (WWPA, ).File Size: KB.

The objec-tives are (I) to provide some understanding of the effects of growth suppression on the charac-teristics of within-tree wood density and tracheid anatomy, and (2) to verify the effectiveness of the approach of ring-width correlation (Zhu et al.

Coastal Douglas-fir prefers the dry, well drained south aspect areas and rainshadow zones often compared to a Mediterranean-type climate. Typically this community is drier and warmer than coastal western hemlock.

As a coastal forest community, this is one of the most imperiled, mainly due to its location which coincides with human settlement pressures as well as being historically an easily. A modified density management diagram for coastal Douglas-fir, James N.

Basic density was estimated for each meter section of log by using a height-based regression equation obtained from approximately wood samples of trees (Douglas-fir) located in the Coastal and Cascade Ranges of Oregon (Acuna and Murphy a).

•The analysis of the responses of Douglas-fir to several fertilization treatments shows that fertilization has a positive effect on SDI as a measure of site carrying capacity.

The results not only show an increase in growth rate but also a change in the trajectory shape when compared to control. Douglas fir is the most widely used wood for building and construction.

In seeds were brought to Europe by the Scottish researcher David Douglas. Up until the Ice Age a related sort was widespread throughout Europe, but only the American relative survived.

The Douglas fir has been planted in Germany and throughout Europe since around Arbutus communities typically occur on dry open marine variant or sloping sites with shallow well-drained exposed rock and rocky soils. Some communities can have deep soil profiles but drainage is key.

Other species associated with arbutus communities include Garry oak, Douglas-fir, lodgepole pine, oceanspray, hairy manzanita (a type of low growing evergreen berry producing plant), salal and.
