A summary is presented of the Needle Trace Method (NTM), which was developed in the late 1980s for Scots pine (Pinus sylvestris). The NTM is based on the examination of the length and location of needle traces embedded in stemwood rather than in the branchwood of a tree - a needle trace connects...

Growth ring widths of roots of windthrown oaks (Quercus robur, Q. petraea), beech (Fagus sylvatica), Scots pine (Pinus sylvestris) and spruce (Picea abies) trees were measured, and data for the period since 1900 are discussed in relation to soil moisture and climatic data.

Growth rings were analysed from young dead Pinus mugo, P. cembra and Larix decidua trees, planted above the present day treeline in Davos, Switzerland, in a study of growth conditions and dieback due to a combination of climatic factors and pathogenic fungi (snow blight (Phacidium infestans) and ...

A 2-part simulation model of the structure of the annual ring is proposed. Part 1 computes the relative rate of growth (cell production) according to the current values of the climatic variables, viz. precipitation, air temperature and soil moisture content. Part 2 transforms these growth data into ...
