N, B, C) vary over time →3-D Find density indices that are relatively stable More flexibility and accuracy require: Dynamic models More than 2 dimensions (for unmanaged stands) Abbott () described a two-dimensional world.
A VARIABLE DENSITY STAND LEVEL GROWTH AND YIELD MODEL FOR EVEN-AGED NATURAL LONGLEAF PINE Dwight K. Lauer and John S. Kush INTRODUCTION L ongleaf pine (Pinus palustris Mill.) stands cover some 3 million widely distributed and fragmented acres in the South of which million acres (91 percent) sup.

Related/Analytical: A variable density stand table projection system calibrated for mixed conifer and. The Government of British Columbia develops and maintains a suite of stand-level models and tools to predict the growth and yield of the province’s future forests.
These predictions support forest sustainability decisions in silviculture planning, forest analysis and inventory activities. Using national yield tables as a basis, the growth of Scots pine Pinus sylvestris L., Lodgepole pine Pinus contorta Douglas ex Loud., Norway spruce Picea abies (L.) Karst.
and Sitka spruce Picea sitchensis (Bong.) Carr. have been compared. From the trends of height growth with age and the levels of total volume production the paper attempts to relate the differences in growth in the Cited by: The objective of this study was to develop an enhanced modular-based structural stand density management model (SSDMM) and associated algorithmic analogue for upland black spruce (Picea mariana (Mill) BSP.) stand-types situated within the central portion of the Canadian Boreal Forest a given density management regime, site quality, rotation age, stock-type, Cited by: The high significance of zonal effects suggests that a separate yield table for lodgepole pine in each zone is warranted, unless appropriate adjustments are made for site index and stand density.
Yield of pure lodgepole pine stands exceeds those of lodgepole pine conifer mixed type and lodgepole pine hardwood mixed types. This banner text can have markup. web; books; video; audio; software; images; Toggle navigation. Watershed management aspects of thinned young lodgepole pine stands.

For example, seed collected from natural stands of western white pine can be transferred up to m in elevation up or down from the site of collection to the planting site, while lodgepole pine. Height models for juvenile even aged mixed-species stands were developed for locations near Nelson, British Columbia.
Separate models were developed for each conifer species found, as well as for paper birch (Betula papyrifera). The objectives were to develop models for: 1) the number of years to reach breast height; 2) height achieved at a given age above breast height.

In reality, these do not form discrete classes, but rather reflect a continuum from normal yield tables, through variable density yield tables and other approaches.
