What is A Method for the Analysis of Temporal Changes in Vegetation Pattern at the Landscape Level about?

A new approach to study temporary changes in small landscape units is proposed, based on vegetationcomplex relev6s (sigma relev6s). The method is introduced using extensively grazed or abandoned heathland and Nardus-sward landscapes in the Black Forest as examples. Thirty-six sigma relev6s of the years 1979-80 are compared with those of 1989-90. Each of the compared plot areas covers on the average 2-4 hectares, and has a diversity of about 20 different vegetation types. The vegetation complex relev6s can be ordered to 3 different types which characterize landscape ecological zones dependant on former rural management. As a result of the comparison 2 main developments which have a spatial differentiation in the Black Forest are confirmed and documentated: 1. Changes of the inventory of vegetation types caused by abandoness. ## 2. Changes of the inventory of vegetation types caused by fertilizer influence. A serious decline can be regarded concerning indicator communities which have no or nearly no fertilizer influence. This decline is proved statistically. The method gives an opportunity for monitoring a definable matrix of vegetation types (the actual 'status quo'). If it is compa
