Studies of weed vegetation by using Braun-Blanquet method have been traditional in the north-western Balkans but only studies based on synoptic tables of weed vegetation have so far been conducted in the area of the former Yugoslvia. Over the past two years, all available releves of weed vegetation (4258) in the area have been collected in a database, which we have analysed using the latest method of multivariate analysis in different statistical softwares, such as JUICE, CANOCO, PC-ORD, etc. The results of classifiaction, indirect and direct ordination and application of indirect values (Pignatti, Raunkier forms) in the analysis of weed vegetation are shown on examples from the former Yugoslavia, and wiil be compared to results acquired under the conventional approach of Braun-Blanquet school. It will show the advantages of the new approach in studies and interpretation of weed or any other type of vegetation.
