Dynamics of an Uneven-Aged Forest Stand

Forest Science, 1972
Abstract The components of net growth for number of trees and basal area are described as a system of first-order, ordinary differential equations for an uneven-aged forest stand. Data from a 6-year period are utilized to estimate coefficients for the governing equations.

Density and the Growth of Even-Aged Stands

Forest Science, 2002
Abstract This study develops a density-driven module and combines it with conventional growth equations, making the resulting model applicable to managed stands. The relationship between the diameter increment of an average tree and density evolves from the analysis of amount of light coming to the unshaded (upper) part of the crown ...

STAND: A Decision Support System for the Management of Even-Aged Stands in Finland

2006
A stand-level decision support system STAND can be used to study how forest management should change alongside changing goals. Such guidelines are laid down by a combined use of a simulation model and numerical optimization. The tree-level simulation model accommodates the relationships between management actions and outputs that the forest produces ...

Stand and tree dynamics in uneven-aged interior Douglas-fir stands

2009
The Interior Douglas-fir Biogeoclimatic Zone covers 4 million hectares in the southern interior of British Columbia. This zone is dominated by interior Douglas-fir forests which are valued for their timber, wildlife, range and recreational values. Interior Douglas-fir can be found growing naturally in uneven-aged structured stands; a structure that ...

Promotion of teamwork in mountain thinning stands of middle-aged broadleaf stands

Glasnik za šumske pokuse, 2005
The paper presents the research results and the optimisation of teamwork in the exploitation of broadleaf thinning stands in a hilly area. The field research was carried out in the forestry administration area of Bjelovar, the management unit of Ivanska Prigorska Šuma, with a team consisting of six workers.
