RESEARCH PAPER 46 OCTOBER 5D QF O I Il Unbound issue c Does not circulate "t MAXIMUM CROWN-WIDTH EQUATIONS FOR SOUTHWESTERN OREGON TREE SPECIES D.P. PAINE D.W. HANN. Maximum crown width (MCW) equations were developed for 16 tree species found in southwest Oregon.
MCW equations are required to compute the. Largest crown width (LCW) equations for stand-grown trees were developed for 14 tree species found in western Oregon. The equations are used in the growth-and-yield model ORGANON and in the stand-visualization program VIZ4ST.
They were constructed such that LCW equals the maximum crown width of open-grown trees when the crown ratio is equal to by: ORGANON RELATED PUBLICATIONS Equations and Manuals Developed for ORGANON. Paine, D.P.

Quantile regression techniques were used to estimate the maximum crown width and a constrained nonlinear equation was developed for estimating the largest crown width.
We noted an improvement in predictions in 11 of 14 species compared to currently-used largest crown width equations in the by: 1. It characteristically has a wide crown, although there is considerable variation in crown width and continuity [14,57].

Brutian pine (Pinus brutia Ten.) is the most widespread conifer species in the Eastern Mediterranean. Aboveground biomass equations for small diameter brutian pine trees are needed for accurate fuel inventory and to assess carbon sequestration potential.
In this study, we developed tree biomass models based on brutian pine saplings measured in 11 research Cited by: 1. ELSEVIER Forest Ecology and Management 97 () Forest Ecology and Management Biomass equations for sixty-five North American tree species Michael T.

Here, we developed generalized height–diameter (h-d) and basal area growth models for mixed stands of two main forest species in Spain: Scots pine (Pinus sylvestris L.) and Maritime pine (Pinus pinaster Ait.).

Description The minimum and maximum values, means, and standard deviation of 18 characteristics of Douglas f i r, hemlock and cedar were computed on the ALWAC III-E to permit comparisons of the species and to serve as a reference for later discussions on s i l v i c u l t u r a l controls of the most important tree and wood quality factors Cited by: 1.
The study site is a ha natural stand of Abies pinsapo, which occupies the steep slopes (average gradient of 50%) of the northern side of the range Sierra del Pinar de Grazalema, located in the south of Spain (36° 46’ N; 5° 23’ W).
Pinsapo stands typically grow on weathered limestone soils and, due to the exposition of these mountains facing the coast, there are. CWi = competing crown width for the ith tree dbhi = diameter at breast height for the ith tree summed over all trees on an acre.
Coefficients obviously may be adjusted to a per hectare basis as well. CCF produces an index of when all open-grown tree crowns are just touching. Fourwing saltbush (Atriplex canescens (Pursh) Nutt.) is a good species for seeding on Southwestern ranges, but it has a reputation for low germination.

The history of hardwoods in the Pacific Northwest is sometimes characterized by contradictions. Hardwoods have always been valued as useful trees: they have been a raw material resource for homes, furniture,and implements; a source of food for people and game.

The heartwood is rated as very resistant to decay fungi and. These relationships changed with ontogeny, especially for the understory species. Within species, the tree stability safety factor (SSF) and relative crown width decreased exponentially with increasing tree height.
These trends failed to emerge in across-species comparisons and were reversed at a common (low) height. Biennial Bibliography College of Forestry and the Oregon Forest Research Laboratory From the Director Thank you for taking an interest in our work.

The average crown width per site (the horizontal project of the crown for each tree) varies between from 10 to m2. The overall average is 67 m2. The largest crown is m2. The sum of crown width for all the trees within a site.
The results showed: (i) pdf prediction precision of aboveground biomass estimates from one variable equation was more than 95%; (ii) the regressions of aboveground biomass equations improved slightly when tree height and crown width were used together with diameter on breast height, although the contributions to regressions were statistically.Maximum Permissible Velocities.
