Abstract

Three hundred and seventy-seven tree-ring width site chronologies including all eight principal forest tree species within Central Europe (5° to 15°E; 43° to 53°N) are expressed as Cropper-values and mapped using a Geographical Information System (here after referred to as GIS). Spatial...

Abstract

Some results are presented for Abies alba and Pinus sylvestris in the Valais where abrupt long-term growth reduction in annual ring sequences were identified from as early as 1921; greatest damage occurred in the early 1970s. From 1977 onwards, recovery is apparent from the Valais but not from the...

Abstract

An analysis was made of core samples taken from 128 Fagus sylvatica, 99 Picea abies, 65 Pinus sylvestris, 21 Abies alba, 16 Larix decidua and 24 Fraxinus excelsior on 10 sites in a limited area near Bern, Switzerland. Negative and positive indicator years were determined, and attempts made to...

Abstract

Some 6000 increment cores and 3000 stem discs from Scots pine, silver fir and Norway spruce trees growing in different regions of Switzerland were examined for abrupt growth changes persisting for longer than 3 yr. The percentage of trees per site exhibiting growth reduction or recovery, as well as ...

Abstract

Abrupt changes in growth persisting for several years were identified, dated and related to crown condition, site, region and ecological factors, using b.h. cores collected from pine, spruce and fir in several regions of Switzerland. Radial increment was only loosely related to needle density...
