Natural Resource Planning

The establishment of communal conservancies aims to have the local communities share in the benefits especially of wildlife resources, in this way spearheading the conservation of the environment. The Desert Margins Programme in Namibia aimed to develop vegetation resource data for the Otjituuo, Okamatapati, Ozonahi, African Wild Dog, Otjinene, Epukiro, Otjombinde, Omuramba Ua Mbinda, Eiseb and Ondjou communal conservancies, in order to assist with natural resource planning. For this purpose, a phytosociological survey of this area, with 422 relevés, was conducted during 2004. The data was captured in Turboveg and forms part of the Namibian phytosociological database (GIVD AF-NA-001). The data was split into two, representing two major land forms, the ‘hardeveld’ and the ‘sandveld’, respectively. A classification was undertaken using the Modified two-way indicator species analysis (TWINSPAN) procedure. Further refinements, based on field observations and literature sources, were performed using Cocktail procedures. Thirteen vegetation associations were formally described in this article, of which two were subdivided into subassociations. These associations can broadly be grouped into broad-leaved savanna types typical of the central and northern Kalahari of Namibia and microphyll savannas found on the transitions to the Central Plateau. One association, the Burkeo africanae–Pterocarpetum angolensis, forms the southern fringe of the Zambesian Baikiaea Woodlands ecoregion of the World Wildlife Fund, whilst all the other associations fall within the Kalahari Acacia–BaikiaeaWoodlands ecoregion. The Combreto collini–Terminalietum sericeae is the most widespread association and dominates the landscape. Threats to the vegetation include overutilisation and regular fires, both of which could easily lead to desertification. This threat is aggravated by global climate change.Conservation implications: This article described 13 plant associations of the central Kalahari in eastern Namibia, an area hitherto virtually unknown to science. The information presented in this article forms a baseline description, which can be used for future monitoring of the vegetation under communal land use.

The phytosociological database Polish Vegetation Database collects relevés of all vegetation types in Poland. The database was established in 2007 and is located at Department of Biodiversity and Plant Cover Protection, University of Wrocław (<a href="http://synbiot.uni.wroc.pl" target="_blank">http://synbiot.uni.wroc.pl</a>). On March 2012, the database included 40000 relevés collected between 1927 and 2011. Most of relevés was taken from published papers and represents almost all types of habitats of Poland. Large groups of relevés represent meadows and pastures (<em>Molinio-Arrhnehteretrea</em>), broadleaf forests (<em>Querco-Fagetea</em>), arable land communities (<em>Stellarietea</em>), coniferous forests (<em>Vaccinio-Piceetea</em>) and eutrophic reed communities (<em>Phragmitetea</em>). In comparison to other countries in Central Europe, Polish Vegetation Database currently belongs to medium-sized databases, with full functionality and accessibility. The present article describes its development, basic operational information and how it can be used in analysis of vegetation in Poland.

The paper presents a plant community of dry-mesic oak forests that is new to Romania, Potentillo albae-Quercetum petraeae Libbert 1933. This association belongs to Quercion petraeae alliance and its range extends over the subcontinental area of Central Europe. A multivariate analysis (cluster analysis, non-metric multidimensional scaling ordination) of a large phytosociological database was used to identify diagnostic species, interspecific associations and the gradient of species composition. Based on species composition and site parameters, a group of relevees in oak forests that correspond to the diagnosis of Potentillo-Quercetum was identified. The Romanian relevees corresponding to this association were previously assigned, pro parte, to Carici montanae-Quercetum Gergely 1962 and Quercetum robori-petraeae Borza 1959. The relations with these and other potentially related two associations, Genisto tinctoriae-Quercetum petraeae Klika 1932 and Quercetum petraeae-cerris Soó 1963, are discussed. The vegetation and site conditions of the Potentillo albae-Quercetum association in Romania are illustrated in a phytosociological table with 25 relevees and a distribution map is provided.

Comprehensive Study

The phytosociological database as a tool for synthetic and comprehensive study of semi-natural meadows in the Polish part of the Carpathians is presented. It has been developed in the Institute of Nature Conservation of the Polish Academy of Sciences since 2007. All accessible phytosociological relevés were digitalized and stored in a TURBOVEG database. As of January 2013, 4620 relevés have been collected in the database, chiefly from mesic meadows of <em>Arrhenatherion</em> alliance (76%) and mat-grass swards of <em>Nardo-Callunetea</em> class (18%). They were recorded between 1923 and 2012 at an altitude range of 195–2000 m above sea level. For improving territorial coverage of the region by vegetation sampling, since 2009 an extensive field survey has been carried out to collect data from previously unexplored areas and record the actual stage of semi-natural grasslands. As a result 1146 recent unpublished relevés were collected. The statistics of available resources, discussion on the data quality and the application prospects of the database are outlined. The database “Grasslands in the Polish Carpathians” is an intrinsic part of the research on the diversity of vegetation in the Polish Carpathian grasslands, as well as a record of the changes it undergoes.
