A new motpellier maple (Acer monspessulanum L.) site was described in this paper, located on mountain Boranja, in forest management unit ?Istocna Boranja?, above Roguljski potok, on Glogovita kosa ridge. Montpellier maple occurs on elevations between 460 and 480 m a.s.l., on southwestern and western aspect, on very steep slopes with inclination 45? t? 50?. The site area is 874 m2, ?nd coordinates of site centre are: ?=19?13?49.0? and ?=44?25?21.33?. In this site, Montpellier maple occurs in a plant community of hop-hornbeam and manna ash, and considering that Montpellier maple was recorded in all three layers, and that it occurs abundantly in shrub and ground layers, a subassotiation with montpellier maple was set apart (?stryo carpinifoliae-Fraxinetum orni subass. ?ceretosum monspessulanii). According to floristic composition, most plant species belong to the submediterranean floral type, so this community represents an enclave of submediterranean vegetation in the belt of continental beech forests. The community is of azonal character, orographically-edaphically conditioned, and occurs in warmer aspects, on shallow and skeletal rendzina on oolithic limestones.

This paper deals with vegetation in series of sample plots put in the aim to define ecological-vegetational units within forest management unit 'Dubicka gora' and to make basis and scope of future forest management. Research encompassed montane beech forest of Iliyian region (Fagetum montanum illyricum, Fuk. et Stef., 1958) and its more mesic type, forest of beech and Acer obtusatum (Aceri obtusati-Fagetum, Fuk. et Stef., 1963). On the basis of floristic composition and site conditions in the community Fagetum montanum illyricum, four subcommunities were set apart: typicum, aceretosum, drymetosum and geranietosum.

Abstract Background This study was carried out in Gerba Dima Forest, South-Western Ethiopia, to determine the floristic composition, species diversity and community types along environmental gradients. Ninety sample plots having a size of 25 × 25 m (625 m2) were laid by employing stratified random sampling. Nested plots were used to sample plants of different sizes and different environmental variables. All woody plant species with Diameter at breast height (DBH) ≥ 2.5 cm and height ≥ 1.5 m were recorded in 25 m X 25 m plots. Within the major plots, five 3 m x 3 m subplots (9 m2) was used to collect shrubs with dbh < 2.5 cm and > 1.5 m height. Within each 9 m2subplots, two 1 m2 subplots were used to collect data on the species and abundance of herbaceous plants. Hierarchical (agglomerative) cluster analysis was performed using the free statistical software R version 3.6.1 using package cluster to classify the vegetation into plant community types. Redundancy Analysis (RDA) ordination was used in describing the pattern of plant communities along an environmental gradient. Result One hundred and eighty plant species belonging to 145 genera, 69 families and comprising of 15 endemic species were recorded. Cluster analysis resulted in five different plant communities and this result was supported by the ordination result. RDA result showed altitude was the main environmental variable in determining the plant communities. The ANOVA test indicated that the five community types differ significantly from each other with regard to EC and K. Conclusions The studied forest can play a significant role in biodiversity conservation since it harbours high species diversity and richness. Thus, all Stakeholders including Oromia Forest and wildlife enterprise (OFWE) and the regional government should work to designate the forest as a biosphere reserve and being registered under UNESCO.

In this paper, the influence of wildfire on dry pastures and rocky grounds the second year after the fire is followed. The results of field studies are presented in the form of phytocoenological table, by applying clustering techniques (WPGMA) and correspondence analysis (CA). Regrouping of the relevés, in comparison with the first year after fire, indicates that specific and more individual directions in vegetation succession have occurred. The situation remained unchanged, only for the rocky sites affected by the fire, at higher altitudes, in the zone of beech forests where the relevés were still standing separately on the graph, as in the previous season, indicating stability in floristic composition, probably caused by faster moving of the fire over the rocky substrate. The quantitative increase in the number of species and diversity index in comparison to the previous season was registered.

Abstract. Sutomo, Darma IDP, Iryadi R. 2020. Short communication: The dissimilarity in plant species composition of savanna ecosystem along the elevation gradient on Flores Island, East Nusa Tenggara, Indonesia. Biodiversitas 21: 492-496. Savannas in Indonesia are located from west to the east across the archipelago. The objective of this research was to investigate the dissimilarity of floristic composition among savannas at different elevations in Flores. Sixteen sampling plots, each measuring 20 x 20 m were spread over the lowland, midland, and upland savannas. We analyzed the differences in plant community composition among the savannas using NMDS ordination and SIMPER analyses available in PRIMER V.6. As many as 41 species of plants were found in all of the sampling plots. The lowland savanna plant community consisted of Themeda arguens, Zoesya sp., Chromolaena odorata, Crotalaria sp., Adenanthera pavonina, Ocimum sp., Lantana camara in the groundcover layer, and Ziziphus jujube, and Borassus flabellifer at the tree layer. The midland savanna had almost similar composition, except the occurrence of Imperata cylindrica and Leucaena leucocephala, and the upland savanna plant species were Cyperus sp., Polygala paniculata, I. cylindrica, Melastoma malabathricum, C. odorata, Centella asiatica, Vaccinium sp., and Cymbopogon sp. The savannas in Flores were invaded by invasive exotic species, namely L. camara and C. Odorata which may pose serious threat to the existence of savannas.

The association of beech and fir was researched on Mt. Suvobor, on serpentinite bedrock. In the past, the beech and fir forest on Suvobor was not studied, it was just referred to, so the objective of this paper was to study the floristic characteristics of this forest, which will enable its ecological-vegetational differentiation and widen the knowledge on beech and fir associations on serpentinites. The studied plant community is characterised by poor floristic composition and by the absolute domination of fir in the tree layer. In the life form spectrum, the dominant plants are phanerophytes, and the percentage of geophytes is increased, which points out the mesophilous plant community. The spectrum of floral elements indicates the dominance of the Central-European floral element, but also a significant percentage of some more xerophilous elements, which is the consequence of a specific parent rock.

Redundancy Analysis (RDA) ordination was used in describing the pattern of plant communities along an environmental gradient. Result: One hundred and eighty plant species belonging to 145 genera, 69 families and comprising of 15 endemic species were recorded. Of these, 52 species (28.9%) were trees, 6 species (3.33%) were Trees/shrubs, 31 species (17.22%) were shrubs, 76 species (42.22%) were herbs, and 15 species (8.33%) were Lianas. Rubiaceae, Acanthaceae and Asteraceae were the richest family each represented by 11 genera and 11 species (6.11%), 9 genera and 11 species (6.11%), 6 genera and 11 species (6.11%), respectively of total floristic composition. Cluster analysis resulted in five different plant communities and this result was supported by the ordination result. RDA result showed altitude was the main environmental variable in determining the plant communities. The ANOVA test indicated that the five community types differ significantly from each other with regard to Electrical Conductivity and Potassium. Conclusions: Description of floristic diversity of species in Gerba Dima forest revealed the presence of high species diversity and richness. The presence of endemic plant species in the study forest shows the potential of the area for biodiversity conservation.

It was established that fertilizatian favours the development and yield of the underground and above ground plant parts both directly and indirectly, that is by changing the floristic composition of the plant community. The production of net biomass and exchanges of a plant species on permanent meadows is dependent not only on the kind of soil, moisture and fertilization but also on the atmospheric conditions.

Abstract The dryland area in Ethiopia covers a substantial region endowed with diverse plant resources. However, the landmass has received less attention even if it has high ecological, environmental, and economic uses. The present study was conducted in Hirmi woodland vegetation, which is one of the dryland areas in Ethiopia, with the objective of investigating the floristic composition, plant community types, vegetation structure, community-environment relations and its regeneration status. Vegetation and environmental data were collected from 80 sampling plots with a size of 25 m × 25 m designated as the main plots. Diameter at breast height (DBH), height, basal area, density, vertical structure, importance value index (IVI), and frequency were computed. Species diversity and evenness were analyzed using Shannon diversity and evenness indices. The plant community types and vegetation-environment relationships were analyzed using classification and ordination tools, respectively. A total of 171 vascular plant species belonging to 135 genera and 56 families were recorded. About 5.3% of the species were endemic and near-endemic to Ethiopia. The highest number of species was recorded in families Fabaceae (16.4%) and Poaceae (11.7%) followed by Asteraceae (7.0%), Combretaceae, Lamiaceae, and Moraceae (3.5% each). Five plant communities were identified. According to the results from ordination analysis, the floristic composition of these plant communities was significantly affected by altitude, slope, sand, silt, soil organic matter, total nitrogen, and disturbance. The vegetation structure reveals that a large number of individual species was categorized in the lower DBH, frequency, and height classes. The highest Shannon diversity index and evenness values of the study area were 4.21 and 0.95, respectively. Anogeissus leiocarpa, Combretum hartmannianum, Ziziphus mucronata, Terminalia macroptera, and Acacia polyacantha were the species with high IVI. Some endemic plants were in the IUCN red list categories of Ethiopia and Eritrea. The overall regeneration status of the study area was poor because of anthropogenic disturbances and grazing pressures. Although the study area is endowed with high plant species diversity including endemism, it is under poor regeneration status due to various disturbances. To overcome this challenge, integrated management measures including monitoring and application of restoration techniques by taking into consideration the significant environmental factors associated with species diversity as well as observed regeneration status and IUCN threat level of the species are highly recommended.
