Don in Galicia Individual tree growth derived from diameter distribution models. Forest Science Partial-cut stands and old-growth stands (Big Reed Forest Reserve) in both hardwood and mixedwood forest were surveyed in the Munsungan Lake area. 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.   Long-term impacts of prescribed fire on stand structure, growth, mortality, and individual tree vigor in Pinus resinosa forests.

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.

Diameter growth is predicted in two I 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 a 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 of 25 was assigned for both slope and aspect, a value of was Cited by: Individual tree diameter increment model for managed even-aged stands of ponderosa pine throughout the western United States using a multilevel linear mixed effects model July Forest 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.

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 ). Increasing levels of competition should have less effect on individual tree height than on diameter growth (Assman ), although a.
