Canopy closure, which is the ratio of the vertical projection area of the crowns to the area of forest land, can indicate the growth and tending situation of a forest and is of great significance for ...
It has been widely reported that biodiversity, ecosystems, and functional traits are positively interrelated in natural?forest?ecosystems. However, it remains unclear whether these relationships shoul...
Key messageWe used 20years of plot data to analyze the influence of tree growth-mortality balance and species mix on the potential of old stands to sequester carbon from the atmosphere and store carbo...
Stand structure and species diversity are two useful parameters to provide a synthetic measure of forest biodiversity. The stand structure is spatial distribution, mutual position, diameter and height...
The effect of stand density on the resistance of Scots pine (Pinus sylvestris L.) to climatic stress and subsequent response of diameter increment were investigated using data gathered from six long-t...
Stand growth and yield models include whole-stand models, individual-tree models and diameter-distribution models. In this study, the three models were linked by forecast combination and parameter rec...
The paper presents the methodology of virtual stand generation. Virtual stand serves for forestry e-learning as a tool for training of forest tending and demonstration of stand structure and some fore...
The purpose of this research was to develop high resolution digital aerial photography to estimate fundamental stand parameters (number of standing trees, mean tree height, stem volume) in a Larix kae...
We analyzed the streamwater from 33 forested watersheds in Nara Prefecture, Japan, in 2002 to clarify the influences of forest clearcut and subsequent afforestation on streamwater chemistry. Each wate...
Designing policies for long-term forest management is difficult, in part because ecological processes that drive forest structure and composition interact strongly, both spatially and temporally, with...
Over the last six years, the Early Stand Dynamics program of FORREX–Forest Research Extension Partnership has assessed the information needs of the operational silvicultural community. This process ha...
