In this study, the epiphytic bryophyte vegetation of Fagus orientalis forests in Hıdırnebi Plateau (Trabzon, Turkey) was investigated. A total 34 relevés taken from living tree trunks different periods 2020 were analysed according to Braun-Blanquet methodology. As a result analyses, Leskeello nervosae–Pterigynandretum filiformis, filiformis lewinskyetosum rupestris subass. nov., Pseudoleskeello...

The paper provides data on the fl oristic composition of vegetation in anthropogenic habitats suitable for Erigeron × huelsenii, a spontaneous hybrid between the alien E. canadensis and native E. acris s. str. The study is based on 21 phytosociological relevés (vegetation plots) of 5×5 m size made in 2013–2014 in the Polish part of the Lithuanian Lakeland (north-eastern Poland) using the Braun-...

The flora of willow (Salix viminalis L.) plantations consists various plant groups, including plants related to arable land, called segetal plants. Knowledge this is important for maintaining biodiversity in agroecosystems. aim the study was assess central Poland, depending on land use before establishment (arable or fallow) and age plantations. Moreover, also check presence invasive, medicinal...

Aims : This study identified, classified and mapped the different plant communities found on Telperion Nature Reserve. Study area Reserve, Mpumulanga, South Africa. Methods Using a 1:10,000 aerial photograph, was delineated into homogenous physiognomic-physiographic units. 294 sample plots (100 m 2 ) were placed in randomly stratified manner within identified Plant species present recorded allo...

A phytosociological approach to dry forest and cactus communities on the occidental slopes of the Peruvian Andes is presented in base of 164 plots carried out following the Braun-Blanquet method. From them, 52 have been made recently, and the other 112 were taken from the literature. After a multivariate analysis, using a hierarchical clustering and a detendred correspondence analysis, the Acac...

Detailed plant diversity information is lacking for Africa, as for many other regions in the tropics, therefore we have used our collection and observation databases to search for possible indicator groups. Digitization of specimen label data for Burkina Faso from the Herbarium Senckenbergianum (FR) and the Ouagadougou University Herbarium (OUA) led to a database containing 18 000 specimens. Fi...

Species diversity is one of the most important indices used for evaluating the sustainability of forest communities. This study aims to characterize the forest communities and to identify and compare the plant species diversity in the study area. For this purpose, 152 relevés were sampled by a randomized-systematic method, using the Braun-Blanquet scale. Classification of the vegetation was con...
