This article discusses the development of predictive vegetationmapping especially in the context of remote sensing-based vegetationmapping. The A. will illustrate the dependence of predictive vegetationmapping on ecological niche theory, and show
the relationship of regional-scale predictive mapping to the global scale modelling of vegetation in relation to climate, and to animal habitat modelling.

A synthesis with an ecological characterization of the vegetation cover in Romania, related to the geographical conditions. The vegetationmap of Romania (1:2 000 000) included in this book will be used for the vegetationmap of Europe, in course
of elaboration. It contents both the natural vegetation, where it is preserved, and potential vegetation. The books contents also a series of fitocenological tables of the main associations. - (IS)

In this study, a semi-arid shrubland in western New South Wales was used to test a number of vegetation indices developed from Landsat Thematic Mapper sensor data. Vegetation cover varied from a mean of 22% in mid-summer to a mean of 78% in mid
-winter. There was no significant relationship between the Normalised Difference Vegetation Index (NDVI) and summer vegetation cover, though there was a significant relationship with total vegetation cover in winter. The Landsat Thematic Mappervegetation
indices most useful for monitoring vegetation in this semi-arid region are the Stress Related Index and the Australian Arid Rangelands Index.

This paper links vegetational microlandscapes distinguished on the basis of differentiation of actual vegetation with geobotanical sub-districts defined on the basis of differentiation of potential vegetation. For each of these microlandscapes
an actual and potential vegetation, as well as land-use were analyzed; the analysis being performed for an area of ca. 540 km2 of the Vistula River valley. The spatial structure of these microlandscapes was characterized in terms of various landscape metrics

Analysis of the potential vegetation in a 580 km2 fragment of the Nida Syncline. The basic mapping of the area was carried out in June 1983. The topographical basis was sheet 153.4 of Pinczów, at the scale of 1:50.000. The total length of the route
covered on foot in the course of mapping was about 420 km. This implied around 0.7 km of route per 1 km2. The reconnaissance of spatial differentiation of the potential natural vegetation was presented in the form of 1:100.000-scale map. - (DG)
