The long-term conservation of viable ecosystems requires a broader understanding of the ecological processes involved. Because ecosystems react differently to different management practices, it is important to have a description and classification of the vegetation of an area available. As part of a vegetation survey programme for the newly acquired farms to be incorporated into the Mountain Zebra National Park, the vegetation of the Ebenhaezer section was investigated. Ahierarchical classification, vegetation map, description and ecological interpretation of the plant communities of the study area are presented. ATWINSPAN classification, refined by Braun-Blanquet procedures revealed eight distinct plant communities. Habitat factors associated with differences in vegetation include topography, soil form and grazing. Descriptions of the plant communities include diagnostic species as well as prominent and less conspicuous species of the tree, shrub and herbaceous layers.

The Difference

The Kammanassie Mountain is a declared mountain catchment area and a Cape mountain zebra Equus zebra zebra population is preserved on the mountain. The high number of springs on the mountain not only provides water for the animal species but also contributes to overall ecosystem functioning. Long-term conservation of viable ecosystems requires a broader understanding of the ecological processes involved. It was therefore decided that a classification, description and mapping of the spring vegetation of the Kammanassie Mountain be undertaken. A TWINSPAN classification, refined by Braun-Blanquet procedures, revealed 11 major plant communities that could be related to geological origin. Habitat factors associated with differences in vegetation include topography, soil type and grazing. Descriptions of the plant communities include diagnostic species as well as prominent and less conspicuous species of the tree, shrub and herbaceous layers. The results also indicate a high species richness compared to similar regions and the difference between plant communities of wet and dry springs. This data is important for long-term monitoring of the spring ecosystems as well as for the compilation of management plans.

Long-term conservation ecosystems require a broader understanding of the ecological processes involved. Because ecosystems react differently to different management practices, it is important that a description and classification of the vegetation of an area are completed. A vegetation survey of the valley areas of the Kammanassie Nature Reserve was undertaken as part of a larger research project to assess the environmental impacts of large-scale groundwater abstraction from Table Mountain Group aquifers on ecosystems in the reserve. From a TWFNSPAN classification, refined by Braun-Blanquet procedures, 21 plant communities, which can be grouped into 13 major groups, were identified. A classification and description of these communities, as well as a vegetation map of the different areas are presented. Associated gradients in habitat w ere identified by using an ordination algorithm (DECORANA). The diagnostic species as well as the prominent and less conspicuous species of the tree, shrub, forb and grass strata are outlined. The study also resulted in a total number of 481 species being identified and the discovery of a new Erica species. These vegetation surveys and descriptions provide baseline information for management purposes and that allows monitoring as well as similar surveys to be conducted in future.

In 2013–2018 studies of phytocoenotic diversity were carried out in the territory of the National Park “Belovezhskaya Pushcha” (Belarus). As a result, a classification scheme of vegetation was developed based on the floristic approach (Braun-Blanquet method) and a large-scale (1 : 100 000) geobotanical map was made. The map is compiled on the basis of the field data, analysis of remote sensing data, literary and cartographic sources, land and forest inventory materials. The compilation of this geobotanical map was consisted of 4 stages. 1) The pre-field (cameral) stage included: collection of archive data about the investigated territory, selection of space imagery, primary processing of digital images and data visualization, interpretation, automatic non-controlled classification, preliminary map compilation. 2) Field studies provided for surface interpretation of vegetation based on satellite imagery.In total, 1851 complete geobotanical relevés were made during field studies, including 743 forest, 452 mire, 576 meadow, segetal and ruderal plant communities. 3) The post-field (cameral) stage, including the preparation of the cartographic base; the systematization of field materials; the development of the final legend; the systematization of image standards for creating cartographic models; the controlled classification of images with preliminary segmentation by the method of superpixels (SNIC-Simple Non-Iterative Clustering); assessment reliability of classification results; geometric and geographical generalization; making an original map. 4) Field check (verification) of geobotanical map. During the 2018 field season a vegetation map of the protected area was checked with the compilation of the final reliability protocol. The main unit of the map legend, a syntaxon of the floristic classification of vegetation, is the association, however, along with the association, to display the typology of the vegetation cover, syntaxons of as a higher hierarchical rank (union) and lower (options, facies), as well as rankless communities are used. In establishing the names of associations and subassociations and in comparative analysis various regional works were taken into account (Matuszkiewicz, Matuszkiewicz, 1954; Czerwiński, 1978; Faliński, 1991, 1994а, b; Kwiatkowski, 1994; Bulokhov, Solomeshch, 2003; Semenischenkov, 2014; Lądowe ekosystemy…, 2016; Dubyna et al., 2019;). In the legend, the mapped units reflecting the restoration stages of the association are marked with letter indices. Heterogeneous areas consisting of regularly and repeatedly alternating plant communities are presented on the map as complexes (phytocoenoses-complex). In total, the map legend contains 75 mapped vegetation units, including forest — 40, shrub — 4, mire — 13, meadow and wasteland — 11, ruderal and segetal vegetation — 6, deforestation and disturbed forest habitats — 1. Separate units reflect other lands (water, residential development, etc.) The practical application of the geobotanical map for identifying key (important for biodiversity conservation) habitats and developing a science-based approach to the functional zoning of protected areas is shown.

South Africa is well known for its semi-arid lowland areas that have a distinct flora and species composition. Because ecosystems react differently to different management practices, it is important that a description and classification of the vegetation of an area be done. As part of a vegetation survey programme for the newly acquired farms incorporated into the Mountain Zebra National Park, the vegetation of the Ingleside and Welgedacht sections were surveyed following the Braun-Blanquet approach. From a TWINSPAN classification, refined by Braun-Blanquet procedures, 10 shrub and grassland plant communities, which can be grouped into seven major groups, were identified. A classification and description of these communities, as well as a vegetation map are presented. The diagnostic species as well as the prominent and less conspicuous species of the tree, shrub, herb and grass strata are outlined. The area generally comprises lowland communities and higher-lying communities. The lower-lying communities consist mainly of two communities and comprise the largest proportion of the area in hectares. In contrast, the higher-lying communities are more diverse with specific habitats. Using the Ecological Index Method the veld condition and grazing capacity were calculated for each community and the total study area. Large sections of the lowland areas are overgrazed due to previous farming grazing practices while the higher-lying areas that were less accessible to the animals are in a slightly better condition. Overall this has resulted in the area generally being degraded within a high grazing capacity of 30.1 ha/LSU.

The tropical seasonal rainy evergreen broad-leaved forest vegetation of the Cucphoung National Park has been classified and the distribution of plant communities has been shown on the map using the relations of vegetation to geology, geomorphology and pedology. The method of vegetation mapping includes: 1) the identifying of vegetation types in the remote-sensed materials (aerial photographs and satellite images); 2) field work to compile the interpretation keys and to characterize all the communities of a study area; 3) compilation of the final vegetation map using the combined information. In the classification presented a number of different level vegetation units have been identified: formation classes (3), formation sub-classes (3), formation groups (3), formations (4), subformations (10) and communities (19). Communities have been taken as mapping units. So in the vegetation map of the National Park 19 vegetation categories has been shown altogether, among them 13 are natural primary communities, and 6 are the secondary, anthropogenic ones. The secondary succession goes through 3 main stages: grassland herbaceous xerophytic vegetation, xerophytic scrub, dense forest.

Within the Platberg area and the wider Drakensberg region, the shrinking natural resources and the threat posed to biodiversity are of concern to conservation management and require an understanding of long-term ecological processes. The vegetation of Platberg was investigated as part of an ecological survey to establish Afromontane floristic links to the Drakensberg as well as for the management of natural resources. From a TWINSPAN classification, refined by the Braun-Blanquet method, four main plant communities were identified, which were subdivided into fynbos, wetland, a woody/shrub community and grassland. A classification and description of the fynbos are presented in this article.The analysis showed the fynbos divided into two communities comprising four sub-communities and seven variants. The fynbos community had an average of 28.34 species per relevé, ranging from 14 to 54 species per sample plot. Twenty-four endemic or near-endemic Drakensberg Alpine Centre (DAC) species and 22 exotic (alien-invasive) species were recorded. Numerous floristic links with the DAC, Cape flora fynbos and grassland bioregions to the north and west were also found. The description of the fynbos plant communities can serve as a basis for the formulation of management plans for the area.

<em>Abstract.</em>—Riparian and floodplain forests are vital components of landscapes. They are transitional zones (ecotones) between river and upland ecosystems where ecological processes occurring in riparian areas and floodplains connect and interact with those of rivers and streams. These forests are the major source of large wood for streams and rivers. Extensive loss of riparian and floodplain forests around the globe is evident from the dramatically reduced supply of large wood in rivers. Clearly, it is necessary to conserve and restore riparian forests to sustain a supply of wood for rivers. This chapter discusses river and land management practices that are designed to provide a continuous source of large wood for rivers and retain wood once it has entered the channel or floodplain. These management practices include conservation of intact riparian and floodplain forests, restoration of ecological processes necessary to sustain riparian forests in the long term, and management of riparian forests specifically to accelerate recruitment of large wood to rivers and streams.
