Diameter and volume increment of (Fagus orientalis Lipsky) in an intact forest of Nave-Asalem region [PDF]
Beech (F. orientalis Lipsky) is one of the valuable species of Caspian forests of Iran which shares about 30% of the forests growing stock. Measurment of the annual diameter and volume increment of this species is essential for accurate planning and ...

A collection of functions to determine annual tree carbon increment via stem-analysis [PDF]
Stem analysis process is commonly employed in a wide range of applications of forest importance. We developed a program to compute stem increments in terms of volume, biomass and carbon storage. The stem-analysis process involves the felling of the tree, the extraction of a number of cross-sections from the stem and the measuring of ring-width series ...

The influence of weather conditions on annual height increments of Scots pine [PDF]
Abstract Annual height increments are a very important characteristic of Scots pine. They have a direct effect on the determination of the dendrometric properties of a stand, such as volume increment. In the present study the data concern height increments of the main shoot in selected age classes of trees (age 72 to 92 years).
