Decelerating growth in tropical forest trees

Ecology Letters, 2007
Abstract The impacts of global change on tropical forests remain poorly understood. We examined changes in tree growth rates over the past two decades for all species occurring in large (50‐ha) forest dynamics plots in Panama and Malaysia.

Constraints to growth of boreal forests

Nature, 2000
Understanding how the growth of trees at high latitudes in boreal forest is controlled is important for projections of global carbon sequestration and timber production in relation to climate change. Is stem growth of boreal forest trees constrained by the length of the growing season when stem cambial cells divide1, or by the length of the period when

Forest Growth-and-Yield Modelling

Journal of Sustainable Forestry, 1998
Abstract Examples of effective growth-and-yield model implementation and use are documented throughout the forestry world. However, in the perspective of sustainable forestry, comparing the development of management requirements with growth-and-yield research backgrounds, some doubts arise concerning basic research hypotheses.

Old-growth forests of the Acadian Forest Region

Environmental Reviews, 2003
In the absence of sufficient data from directed studies of old-growth forests in the Acadian Forest Region (AFR), we must rely on a general knowledge of forest ecology and natural succession, population biology, disturbance dynamics, and palynological evidence to understand the probable extent of old-growth, late-successional forest types before ...

Forest Growth Models

2008
The progression from prototypes of stand oriented growth models, the yield tables for pure stands from Schwappach and Wiedemann, to stand growth simulators for defined management strategies followed by eco-physiological process models as research tools and landscape and visualisation models for ecosystem management reflect the changes in the aims of ...

Growth releases across a natural canopy gap-forest gradient in old-growth forests

Forest Ecology and Management, 2014
Canopy gaps created by the death of one to a few trees can exert a dominant influence on forest structure and composition by affecting the growth of nearby trees. Previous research in old-growth forests of coastal British Columbia, Canada indicated that most western redcedar (Thuja plicata Donn ex D.

Forest height growth modelling

Forest Ecology and Management, 1995
Abstract There are many functional forms which may be used to model height against age, and a variety of methods by which the model parameters may be estimated. There are four main questions that the forest height modeller needs to decide upon. 1. (1) Should each height-age trajectory be modelled separately? 2.
