Question: We explored the error resulting from different methods for recording the cover of plants in vegetation plots, specifically the direct estimation of percent cover vs. the use of ordinal cover scales (7-step Braun-Blanquet and 5-step Hult-Sernander-Du Rietz). Methods: We simulated 121 plant species of different cover, sampled with 13 different levels of estimation precision. Estimation precision was either based on a constant coefficient of variation (0.1–1.0) across all cover values or on empirical data from Hatton et al. (1986, Journal of Range Management 39: 91–92) (× 0.5, × 1.0, ×

AbstractIn vegetation science including phytosociology, visual estimates of plant cover and point method belong to the common field method to record species composition and their abundance. Two methods were compared: Braun-Blanquet scale and point method using Levy bridge. A group of students performed measurements in five plots belonged to an oak-hornbeam forest Tilio-Carpinetum. It was revealed that there is a very high discrepancy in a observed number of species. Total mean numbers obtained are 13.4 and 31.2 for point method and Braun-Blanquet method respectively. However, there is the sign

The main data on the geobotanical database – Database of antropogenic vegetation of Urals and adjacent territories registered in the Global Index of Vegetation-Plot Databases and the European Vegetation Archive are presented. The database includes more than 4,000 complete geobotanical relevés made between 1984 and 2020. The database contains the territories of 3 subjects of the Russian Federation (the Republic of Bashkortostan, Orenburg, Chelyabinsk regions) and 1 - the Republic of Kazakhstan (Aktobe region).

Question: We asked whether ordinal cover scales cause biases in biodiversity indices derived from vegetation plots and, if so, whether a different back-translation of ordinal categories could improve the situation. Methods: We took three empirical vegetation-plot datasets from different regions and habitat types with species cover estimated in percent. We applied three ordinal cover scales (13-step Londo, 7-step Braun-Blanquet and 5-step Hult-Sernander-Du Rietz) and back-transformed the resulting categories to percent (mid-point of the respective cover class). For each plot, we then calculated

The monitoring was based on 6 localities selected from within different regions of the Czech Republic. The vegetation was monitored during 2005 to 2008. Plant checklists have been made for each locality. Permanent plots of 9 m&lt;SUP&gt;2&lt;/SUP&gt; in size have been marked and the phytosociological relevés have been recorded. The standard Braun-Blanquet scale of abundance/dominance was used. Biological diversity was evaluated using the Shannon, Simpson, and Evennes indexes.

AbstractThe Central Anatolian vegetation has diverse site conditions and small-scale plant diversity. For this reason, identification of plant communities is important for understanding their ecology and nature conservation. This study aims to contribute the syntaxonomical classification of the Central Anatolian vegetation. The study area is situated among Güzelyurt, Narköy, and Bozköy (Niğde) in the east of Aksaray province of Central Anatolia in Turkey. The vegetation data were collected using the phytosociological method of Braun-Blanquet and classified using TWINSPAN. The ecological charac

The study of diversity and ecological-phytocenotic mapping of the vegetation cover was carried out at the key area located in the eastern part of the Echki-Dag mountain range in the territory of the Lisya Bay Reserve (Eastern Crimea). A generalization of the classification and ecological patterns of vegetation was carried out to create a legend for a large-scale ecological-phytocenotic cartographic model (at the scale of 1:10000).
