Online appendix 2:Vegetation of the eastern communal conservancies in Namibia: I. Phytosociological descriptions

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.

Scope and data set of the phytosociological database ‘Grasslands in the Polish Carpathians’

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.

Level of invasion by alien plants across habitats in the basin of the Ploučnice River

The level of invasion varies depending on the type of the habitat. The aim of this paper is to evaluate the level of floral invasion within the basin of the Ploučnice River in Northern Bohemia. The values of the level of invasion were quantified for vegetation plots from the Czech National Phytosociological Database. Several maps documenting the level of invasion by alien plants were developed based on a quantitative assessment of the level of invasion of particular habitat types. The levels of invasion were measured as a proportion of the species that are aliens and as the total cover by alien species, the same was done for archeophytes and neophytes separately. Mean levels of invasion were used for the habitats.
