The Braun-Blanquet technique, complimented by TWINSPAN, was used for a phytosociological classification of the study area. Thirteen plant communities were recognised and described. A hierarchical classification is suggested and each community is related to its particular environmental characteristics.

Mapping Data

Diversity of plant communities in the nature reserve “Privolzhskaya Forest-Steppe”, Ostrovtsovsky area, is analyzed on the basis of the large-scale vegetation mapping data from 2000. The plant community classi­fication based on the Russian ecologic-phytocoenotic approach is carried out. 12 plant formations and 21 associations are distinguished according to dominant species and a combination of ecologic-phytocoenotic groups of species. A list of vegetation classification units as well as the characteristics of theshrub and woody communities are given in this paper.

The Marloth Nature Reserve, encompassing the mountain catchments of the southern Langeberg immediately above Swellendam, Cape Province. South Africa, is described. The vegetation of the reserve was sampled along a transect representing the variation in plant communities over the range from the lower south to the lower north slopes. Eighty-three sample sites were subjectively located in mature stands of fynbos vegetation (10 years old). The relev£ data were initially classified using TWINSPAN and then refined by Braun-Blanquet (BB) phytosociological procedures. The Afromontane Forest patches which occur mainly on the lower south slopes were not sampled but are briefly discussed. The fynbos plant communities are described, based on tables, and a hierarchical classification is proposed.

Ecological Basis

After classifications and descriptions of the southern and western sections of the Borakalalo Nature Reserve were published, a study on the phytosociology of the northern part was initiated. The study is aimed at providing an ecological basis for establishing an efficient wildlife management programme for the reserve. From a TWINSPAN classification, refined by Braun-Blanquet procedures, 15 plant communities, which can be grouped into six major plant communities, were identified. Descriptions of the various plant communities, include diagnostic species, prominent species and less conspicuous species of the tree, shrub, forb and grass strata. A hierarchical classification, description of the plant communities and a vegetation map are presented.

AbstractThis paper proposes a new objectively-generated vegetation classification for southern and northern Victoria Land (continental Antarctica) based on the floristic composition of the plant communities. The new classification aims to integrate the existing physiognomic classification of the cryptogamic Antarctic tundra, provide useful data on floristic composition and distribution of the vegetation occurring in southern and northern Victoria Land, and develop a suitable tool allowing easy comparison of syntaxa from different locations. Field data from 26 sites along a latitudinal gradient (72°–77°S) were analysed by a hierarchical classification integrated with multivariate statistics, including indirect ecological information (Principal Component Analysis). Similarity of the identified groups was assessed through the Jaccard similarity index. The new classification is compatible with previous ones and is widely applicable to Victoria Land and includes previous classification. This standardized approach relates plant communities to their floristic composition and provides a basis for relating vegetation composition to environmental gradients and to patterns of vegetation dynamics and succession which are still poorly understood in Antarctica.

An analysis of the fynbos shrublands and forests of the Boosmansbos Wilderness Area, southern Langeberg, Cape Province, South Africa, is presented. Data were collected at 119 sites in mature fynbos vegetation (10 years old) and at five sites in patches of Afromontane Forest. Emphasis was placed on the fynbos shrublands and sample sites were subjectively located along a transect from south to north across the Langeberg range in the study area. This south to north orientation follows a complex gradient of changes in aspect, slope, geology, soil form and climate. Data were initially analysed using TWINSPAN and the resulting classification refined using Braun-Blanquet procedures. One forest subassociation and 12 fynbos communities were identified and described. A proposed hierarchical classification of the fynbos communities is presented.

An analysis of the vegetation of the Honnet Nature Reserve, Northern Province is presented. Releves were compiled in 56 stratified random sample plots. The Braun- Blanquet procedure revealed 12 distinct plant communities and four sub-communities. The Variable Quadrant Plot Method was used in the structural analysis of the communities and management units. The data were ordinated using Detrended Correspondence Analysis (DECORANA) to determine possible relations and gradients between and in the plant communities. Six management units were identified by means of the vegetation ordination, plant communities and the physical environment. A hierarchical classification, description and ecological interpretation of the vegetation units and a descrip- tion of the management units are presented.

A classification of the plant communities occurring there is given. A way by which a hierarchical classification of plant communities in South Africa community is physiognomically classified according of this system are discussed briefly.could be constructed, is suggested. Each plant to Fosberg's (1967) system. Two disadvantages of this system are discussed briefly.

The fynbos shrubland communities of the southeastern Langeberg. Cape Province were analysed after sampling 97 quadrats in the Bergfontein, Rooiwaterspruit (Garcia's Forest Reserve) and Phesantefontein areas. Data were initially analysed using TWINSPAN and the resulting classification refined using Braun-Blanquet (BB) procedures. One Afromontane forest community and 16 fynbos communities are recognized and described. A hierarchical classification of the fynbos communities is proposed.

Abstract The article presents the information about the current state of the larch forests of the “Bastak”. State Nature Reserve The area, ecological and cenotic conditions of growth are determined, the classification of the studied plant communities is presented, a brief description of the forest structure is given. The current state of the larch forests of the “Bastak” State Nature Reserve can be assessed as fairly stable. Currently, larch forests occupy within 25 % of the forested area. The most widespread area is occupied by lowland larch forests (94 %). Mountain larch forests are derived plant communities formed after forest cutting in fir-spruce forests.
