Abstract:
The nitrogen fertilization of boreal forests is investigated in terms of microeconomics as a tool for carbon sequestration. The effects of nitrogen fertilization’s timing on the return rate on capital and the expected value of the timber stock are investigated within a set of semi-fertile, spruce-dominated boreal stands using an inventory-based growth model. Early fertilization tends to shorten rotations, reducing timber stock and carbon storage. The same applies to fertilization after the second thinning. Fertilization applied ten years before stand maturity is profitable and increases the ti

A study of aspen sucker stands subjected to repeated harvesting at the Petawawa National Forestry Institute compared biomass production at rotations of 1, 2, 3, 5, 8,13, and 20 years. The shortest rotation at which sucker production can be physiologically sustained is unlikely to be less than 10 years. Biomass mean annual increment appeared to culminate at about 15 years. Declining yields at the shorter rotations were thought due mainly to starvation of rootstocks by the frequent removal of the photosynthesizing tops on which they depend for nourishment.

Abstract:
Forest management decisions affect carbon stock and rates of sequestration. One subject of debate is the rotation age that will optimize sequestration over extended periods. Some argue that shorter rotations facilitate greater sequestration rates due to the accelerated growth rates of younger trees compared to mature or old-growth trees. Others maintain that frequent harvesting will not allow forest carbon to rebound after each subsequent rotation, and thus more extended periods between clearcutting is the superior choice. These contrasting viewpoints are mirrored regarding the impact of thinn

Abstract A survey of short-rotation forestry research from 1966-82 provided insights into the political, socioeconomic, institutional, and personal factors influencing decisions made by forestry researchers.

AbstractLandscape multifunctionality, a widely accepted challenge for boreal forests, aims to simultaneously provide timber, non-timber ecosystem services, and shelter for biodiversity. However, multifunctionality requires the use of novel forest management regimes optimally combined over the landscape, and an increased share of sets asides. It remains unclear how this combination will shape stand vulnerability to wind disturbances and exposed timber volume. We combined forest growth simulations and multi-objective optimization to create alternative landscape level forest management scenarios.

Abstract:
Probability theory is applied to the effect of severe disturbances on the return rate on capital within multiannual stands growing crops. Two management regimes are discussed, rotations of even-aged plants on the one hand, and uneven-aged semi-stationary state on the other. The effect of any disturbance appears two-fold, contributing to both earnings and capitalization. Results are illustrated using data from a recently published study, regarding spruce (Picea abies) forests in Austria. The economic results differ from those of the paper where the data is presented, here indicating continuous-

Abstract:
Abstract Existing risk-rotation models for forest stands assume risk-neutrality on the part of decision makers. The criterion by which the optimal economic rotation is chosen in such models is based on the maximum expected discounted value of the site. Economic theory suggests, however, that many individuals are risk-averse and do not make investment decisions based solely on the mean of the distribution of investment returns. Models assuming risk-neutrality do not necessarily identify the appropriate economic rotation for such investors. Stochastic dominance analysis is employed to incorporat

Abstract:
The commercial cost-effectiveness of poplar cultivation and commercial cost-effectiveness of long-rotation (42-year) poplar plantation were analyzed. The aim of the research is, based on analysis of expenses and receipts during the period of 42 years and by applying the method of analysis of the project commercial cost-effectiveness, to show the justification of long rotations in poplar plantations. Modern methods of investment valuation were applied and consequently their practical application in forestry was confirmed.

Abstract:
The good fairy problem reexamines the question of the optimum age to harvest a stand of trees. The metaphor of a financial portfolio reveals the sense in which the financial rotation age is optimal and the sense in which the rotation age that maximizes the mean annual increment in net value is optimal. This metaphor clarifies the distinction between economic efficiency and forest policy. In particular, it indicates the ultimate inevitability of the financial rotation age while demonstrating that the financial rotation age implicitly rejects the notion of sustained yield.

Abstract:
Carbon sequestration through forestry represents a promising approach to partially counteract anthropogenic greenhouse gas emissions driving climate change. Tree growth naturally removes carbon dioxide from the atmosphere, storing it as biomass. Sustainably managed forests can effectively function as carbon sinks. However, determining optimal forestry policies involves balancing complex ecological dynamics with economic constraints. This study develops differential equation models quantitatively capturing forest growth, timber harvesting, and carbon sequestration dynamics. Logistic models are

Sustainability in forestry does not only cover wood production but it serves all functions of the forest. The increasing demand for wood urges a reconsideration of management concepts. To further ensure the principle of sustainability with the forest as a natural tool for resources, all potentials of the cultural landscape for woody biomass production are to be considered with the strategies for a sustainable development. Such a potential is offered by short-rotation plantations at agricultural sites. Management of such plantations in the agricultural landscape must meet minimum standards in r

The sectoral documents of strategic goal-setting and planning define the intensification of forest use and reproduction as one of the tasks of the state forest policy of Russia. As part of the implementation of the intensive forestry model, the need for planning and evaluating economic efficiency within the duration of the forest reproduction cycle has been established. However, the mechanism for implementing these installations is not proposed in official documents. The duration of the production cycle of forest cultivation among all types of economic activity is unprecedented. The article sh

Abstract:
Abstract Based on a perpetual rotation assumption, changes in selected variables will have effects on the even-aged timber clearcut age (rotation) that maximizes net present value using the Faustmann formula. Alternatively, one can assume that landowners project a postharvest change in land use with a land value equal to or exceeding today's Faustmann value and that this future land value is independent of their assumed values for variables like annual costs, annual revenues, stumpage prices, and income taxes. In that case, the impact of changes in the foregoing variables on optimal rotations

Abstract This article examines biodiversity conservation in commercial boreal forests. The means of promoting biodiversity are green tree retention and prolonged rotation age, which create dead and decaying wood artificially and via natural mortality, respectively. We extend the Hartman model to cover biodiversity benefits and to allow for leaving retention trees standing at the final felling. We first characterize qualitatively the socially optimal choice of the harvest volume and rotation age. We then assess empirically the optimal solution in a simulation model calibrated to the Finnish for

The system for measuring the welding temperature with measuring probes has been developed for the requirements of this but also of future research (at the Faculty of Forestry and Wood Technology, University of Zagreb). The research is based on determining the welding temperature and its impact on the joint strength or the embedded force of the dowel. Based on research results, the impact of the dowel rotation frequency and temperature on the joint strength has been determined. The measured welding temperature increased as the rotation frequency increased (the rotation frequencies of 865 min-1
