Economic Growth and the Rise of Forests

The Quarterly Journal of Economics, 2002
Although forests have diminished globally over the past 400 years, forest cover has increased in some areas, including India in the last two decades. Aggregate time-series evidence on forest growth rates and income growth across countries and within India and a newly-assembled data set that combines national household survey data, census data and ...

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

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-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.

A similarity criterion for the forest stand growth

Doklady Biological Sciences, 2012
The authors try to deduce the likelihood criterion on the ground of a dimensionless approach (the Buckingham \(\pi\)-theorem) , and to apply these findings to the growth of crownpiece of tree. The relation of thus produced one-parameter curve to the well-known Chapman-Richards four-parameter curve is discussed.

A Stochastic Model for Forest Fire Growth

INFOR: Information Systems and Operational Research, 2007
Abstract We consider a stochastic fire growth model, with the aim of predicting the behavior of large forest fires. Such a model can describe not only average growth, but also the variability of the growth. Fire is modeled as a random phenomenon on a regular spatial grid, specifically, an interacting particle system modeled as a continuous‐time Markov ...

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 ...

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.

Modelling mixed forest growth: a review of models for forest management

Ecological Modelling, 2002
Abstract Most forests today are multi-specific and heterogeneous forests (‘mixed forests’). However, forest modelling has been focusing on mono-specific stands for a long time, only recently have models been developed for mixed forests. Previous reviews of mixed forest modelling were restricted to certain categories of models only and were generally ...
