A distance-independent, individual- tree diameter growth model was de- veloped for managed, even-aged, upland oak stands. The 5-year basal- area growth of individual trees is first modeled as a function of dbh squared for given stands.

Abstract ~. I I Describes a species-specific, distance-independent individual-tree diameter growth 1 model for the Northeastern United States. Diameter growth is predicted in two Even-aged steps using a two parameter, sigmoidal growth function modified by a one parameter exponential decay function with species-specific coefficients.
Coefficients are presented for 28 species by: Research also suggests that even-aged distance-independent, individual-tree model structure is flexible enough to predict diameter growth in pure even-aged stands as well as in mixed, multi-aged stands (Monserud and Sterba,Porté and Bartelink,Calama et al., ).Cited by: An individual-tree diameter growth model for managed uneven-aged oak-shortleaf pine stands in the Ozark Highlands of Missouri, USA Article in Forest Ecology and Management (3)– Five-year periodic annual increment (PAI) in diameter by initial diameter at breast height (dbh) and site index (SI) for managed even-aged stands of ponderosa pine throughout western United States using the coefficients in Table 6 (a value of 40 was assigned for latitude, a value even-aged 25 was assigned for both slope upland oak stands book aspect, a value of was Cited by: Individual tree diameter increment model for managed even-aged stands upland oak stands book ponderosa pine throughout the western United States using a multilevel linear mixed effects model July Even-aged Ecology.

We examined four individual tree models in Europe: BWIN, Moses, Silva and Prognaus. We simulated growth of open-grown trees and on research plots for 15 or 30 years. Height:diameter ratios were correctly predicted by all four models.

increasing competition in even-aged stands, it might be ex-pected that trees will have thinner crowns and shorter crown lengths under increasing levels of competition (Smith and Long ; Hökkä and Groot ).

The aim of this research was to develop a stand-class growth and yield model based on the diameter growth dynamics of Pinus spp.
and Quercus spp. of Mexico’s mixed temperate forests. Using a total of temporary, circular-sampling plots of m2 each, nine Weibull distribution techniques of parameter estimation were fitted to the diameter structures of pines and by: 2.
Research Highlights: The influence of litter raking and livestock grazing on the development of juvenile sessile oak and European hornbeam sprouts as well as on sessile oak standards were studied. Such experiments are very rare, especially in central Europe where these activities have been prohibited for several decades.
Little is known on how these ancient management activities affect tree Cited by: 1. An individual-tree basal area growth model previously developed for even-aged naturally occurring shortleaf pine trees in western Arkansas and southeastern Oklahoma did not include weather variables.

We encountered 87 bird species overall. Fourteen species had their highest abundance in clearcuts and young even-aged, regenerating forest. Three species were most abundant in medium-age forest. Decline of oaks in upland hardwood and mixed oak-pine forests is a complex involving environmental stressors (often drought), root diseases, insect pests of opportunity such as the two-lined chestnut borer (Agrilus bilineatus), introduced pests such as the Japanese beetle (Popillia japonica) and Asiatic oak weevil (Cyrtepistomus castaneus), and.

Gap models are perhaps the most widely used class of individual-based tree models used in ecology and climate change research. However, most gap model emphasize, in terms of process detail, computer code, and validation effort, tree growth with little attention to the simulation of plant death or mortality.
Mortality algorithms have been mostly limited to general relationships because of Cited by: Content Posted in Laboratory Prediction of Phosphorus Release From Deciduous Leaves to Urban Runoff, Heather Culbert and Robert France.

Most forest stands in the United States, when first viewed by European settlers, were even-aged stands.
They were the product of local catastrophies -- fire, storm, insects, and disease. In attempting to continue with even-aged management we are not going contrary to the pattern in nature. The growth of two Scots pine stands of the forest type Vaccinio-myrtillosa has been observed in the course of 16 years.
The initial age varied from 4 to 8 years, while the initial density was in the range of 5, trees/ha.
Both stands are planted, one on former agricultural land. In this dissertation, a consistent, reasonably precise, verifiable system of stand structure classification was developed and demonstrated. The goal was to provide a foundation for better communication amongst forest management professionals.
A novel distance metric and classification algorithm were introduced. The distance metric was based on similarity in reversed cumulative stems and basal Cited by: 2. 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 (height yield); 3.
These curves were developed for use in pure, even-aged stands of red pine. A pure stand is one in which at least 80 percent of the trees are of the same species. An even-aged stand is one where the age difference between the youngest and oldest tree in a stand.
Aside from model type, forest growth models can be defined by the base unit of representation: whole stand or individual tree models, and by their spatial representation: distance-dependent and distance-independent (Figure ). Stand models simulate growth and yield through parameters that define the underlying diameter distribution, for instance.
The forested ecosystem is represented as a series of vegetation and soil components. The model provides for both an overstory and understory, each of which can be divided into canopy, bole, and roots. Tree growth in the model is a function of user-defined stand developmental stage and the availability of nutrients and moisture.
Abstract: This illustrated review is aimed to provide succinct account of different methods applicable for obtaining objective information about the functional ecology of forest sites and stands (and also, e.g., orchards, watersheds, parks or alleys) for the purposes of phytotechnology or precise forestry.
Management strategies must consider preservation of many important functions of forests Cited by: 4. First results show that increasing tree pdf in even-aged pdf affects tree growth, mortality, biomass production or infection by pests and pathogens.
Hence, biodiversity might not only be seen as a good to monitor and to preserve, but also as a tool to optimise and stabilise multiple functions in plantation forestry.They evaluated a whole-stand (Sullivan and Clutter, ) and an individual-tree (Amateis download pdf al., ) growth and yield model for loblolly pine for the purpose of updating forest inventory data.
Both of the growth and yield models were evaluated at varying projection periods by using permanent plots measured at 0, 3, 6 and 9 years after 5/5(1).Modeling the effect of thinning on the diameter distribution of even-aged Maritime pine stands.
