Background on Vegetation Classification Systems
2016Vegetation is formed by plant species growing as the result of a long development process consistent with the places they inhabit and which constitutes a fundamental part of ecosystems. As a result, vegetation is understood as resulting from the effects of various environmental factors on sets of species which cohabit in a determined space and period ...

Vegetation Diversity and Classification Systems
1993The first modern attempt to classify and characterize vegetation and to relate it to environment can be traced to the beginning of the 19th century, to Alexander von Humboldt. Humboldt made extensive surveys of South America and tried to explain vegetation differentiation in relation to environmental characteristics, in particular those of the climate (

Classification of dry grassland vegetation in Denmark
Journal of Vegetation Science, 2000Abstract. A hierarchic classification of Danish semi‐natural grassland vegetation on well‐drained soils is presented. TWINSPAN was used for clustering of 614 samples of grassland vegetation showing floristic gradients and turnover in species composition in more dimensions.

Formalised classification of aquatic vegetation in Slovakia*
Phytocoenologia, 2019Based on new Cocktail approach, we produced clear syntaxonomical classification of aquatic vegetation in Slovakia with a low number of non-classified or multiply classified relevés. Within three classes selected for the analyses (Lemnetea, Potamogetonetea and Charetea intermediae), altogether 8 orders, 9 alliances, and 55 associations were ...

The repeatability of vegetation classification and mapping
Journal of Environmental Management, 2011The mapping of habitats as defined by plant communities is a common component of the planning and monitoring of conservation management. However, there are major concerns about the subjectivity and risk of observer bias in most commonly used plant community mapping protocols.

The Classification of Vegetation
1988Every map that shows differences of vegetation implies a classification, and one might argue that every vegetation map is an application of the classification which a particular author happens to choose. This leads to the conclusion that the relation between classifying and mapping vegetation is that of a sequence in which the first item ...

A Physiognomic Classification of Vegetation
Annals of the Association of American Geographers, 1949T is the task of biogeogrjhy to describe and explain the distribution of organisms I on earth. The use of maps as basic tools is inevitable, but, so far, vegetation maps have contributed little to studies of a world wide character. It is no longer possible to investigate the vegetation of an area without considering that of the neighboring regions, of ...

JUICE, software for vegetation classification
Journal of Vegetation Science, 2002Abstract. The program JUICE was designed as a Microsoft® WINDOWS® application for editing, classification and analysis of large phytosociological tables and databases. This software, with a current maximum capacity of 30 000 relevés in one table, includes many functions for easy manipulation of table and header data.

Ecological Classification of World Vegetation
1981The area of plant ecology which deals with the relation of plant structure (including its seasonal variation) to environmental conditions has been called ecophysiognomy (Mooney 1974). One of the most conspicuous (and gratifying) features of plant structure is that it tends to converge to certain successful structural-functional forms, which can be ...

Ordination, Classification and Vegetational Boundaries
1974In recent years there has been a considerable controversy over the relative merits of classification and.ordination in the study of vegetation.Classification implies the division of the individuals or units being classified into categories or classes, whose members show a greater or less degree of similarity a-mongst themselves, and differ from members
