“…and they are not considered as syntaxa. The same holds for abstract phytocoenotic units derived from the integration of abstract synusial units (“coenassociations”).

Note 2: Floristic‐sociological criteria involve focussing on complete floristic inventory of species, often associated with an indication of relative importance based on projected cover or specimen counts in spatially delimited vegetation sampling plots called relevés, or frequency and/or presence degree across a set of relevés. These data elements are the subject of classification and lead to formulation of abstract floristic‐based vegetation units characterised by species (character species, differential species) and/or species groups bearing delimitation power.

The 4th edition of the International Code of Phytosociological Nomenclature (ICPN) was prepared by the Steering Committee of the IAVS Working Group for Phytosociological Nomenclature (GPN). The edition consists of 14 Definitions, 7 Principles, 53 Articles, and 7 Appendices. When compared with the previous edition, the main amendments are (1) the acceptance of electronic publications (Art. 1), (2) the introduction of binding decisions (Definition XIV, Principle II, Articles 1, 2b, 3c, 29b, 40, 42, 44, Appendices VI and VII), (3) the mandatory use of the English or the Latin terminology for syntaxonomic novelties (Definition II, Principle II, Articles 3d and 3i), (4) the introduction of autonyms for the main ranks when the corresponding secondary ranks are created (Articles 13b and 24), (5) the automatic correction of the taxon names (name-giving taxa) used in the names of syntaxa in accordance with the International Code of Nomenclature for algae, fungi, and plants (ICN) (Article 44), (6) the possibility to mutate the name of a syntaxon in using another correct, alternative name for the name-giving taxa (Article 45), (7) the Accepted Article This article is protected by copyright.

“…In line with other systems in countries where managing existing natural vegetation types is the primary purpose of the system, the ecological scope of the RE system is confined to natural 'remnant' vegetation, (Brown and Bredenkamp 2018;MacKenzie and Meidinger 2018;Walker et al 2018;Wiser and De Cáceres 2018). In countries where highly modified landscapes predominate, semi-natural and cultural vegetation types are included in their classification system (Gillet and Julve 2018;Guarino et al 2018;Rodwell 2018; Federal Geographic Data Vegetation Subcommittee, see http:// usnvc.org/revisions/) Major differences become apparent when the procedural elements are compared (Table 1). A major difference is that the RE system uses dominant species to identify plant communities.…”

Aligning quantitative vegetation classification and landscape scale mapping: updating the classification approach of the Regional Ecosystem classification system used in Queensland

2021

Vegetation classification systems form a base for conservation management and the ecological exploration of the patterns and drivers of species' distributions. A standardised system crossing administrative and geographical boundaries is widely recognised as most useful for broad-scale management. The Queensland Government, recognising this, uses the Regional Ecosystem (RE) classification system and accompanying mapping as a state-wide standardised vegetation classification system. This system informs legislation and policy at local, state and national levels, underpinning decisions that have wide-ranging implications for biodiversity and people's livelihoods. It therefore needs to be robust from a scientific and legal perspective. The current approach in the RE system for identifying vegetation communities relies on expert-based class definition procedures. This is in contrast to best practice, which is based on quantitative procedures. This paper discusses the RE system in a global context and outlines the updated approach that incorporates quantitative class definition procedures, synthesises the research behind the updated approach and discusses its implications and implementation.

“…This classification was based on synusial data (i.e. trees, shrubs, dwarf shrubs and grasses only) (Gillet & Julve 2018), and resulted in three clusters. These clusters were interpreted as representing the Pre-Namib and Escarpment zone, the central Khomas Hochland as well as a third group comprising riverine habitats and lowlands surrounding the Khomas Hochland.…”

Vegetation survey of the Khomas Hochland in central-western Namibia: syntaxonomical descriptions

Background: The Great Escarpment of southern Africa takes the form of an extended mountainous highland in central-western Namibia, commonly referred to as the ‘Khomas Hochland’. It is regarded as an area of high botanical diversity. Yet only few localised studies on the vegetation composition are available. The Khomas Hochland is formed on the southern part of the Damara Orogen and dominated by metamorphosed sediments. Climatically it forms a transition between the hot desert of the Namib and the slightly cooler hot steppe in the inland.Objectives: To classify and provide syntaxonomical descriptions of the vegetation of the Khomas Hochland.Methods: A dataset comprising 1151 relevés and 914 species was compiled from various surveys, mostly collected under, and to the standards of, the umbrella project ‘Vegetation Survey of Namibia’. For first classifications, the data set was reduced to a synusial set consisting of trees, shrubs, dwarf shrubs and grasses only.Results: The classification resulted in four major landscape units, being the Pre-Namib and Escarpment zone, the Khomas Hochland proper, riverine habitats as well as surrounding lowlands. The classification was further refined using Cocktail procedures to produce 30 associations, one with four sub-associations. These are described in this paper.Conclusion: A classification of synoptic data grouped the associations into five orders and one undefined cluster of associations on specialised desert habitats. Four of these orders correspond to the habitat types identified in the first classification. The fifth order, the Senegalio hereroensis–Tarchonanthoetalia camphorathi, represents high mountains of the central Khomas Hochland, which link biogeographically to the grassland biome in South Africa.
