Floristic diversity of selected plant communities on extensive and abandoned grasslands in the Nadwieprzański Landscape Park / Zróżnicowanie florystyczne wybranych zbiorowisk roślinnych ekstensywnych użytków zielonych w Nadwieprzańskim Parku Krajobrazowym

Abstract The paper presents floristic diversity of some plant communities in the Nadwieprzański Landscape Park (middle part of the Wieprz River valley). Phytosociological relevés were made in the years 2005-2007 with Braun-Blanquet method. Species richness was a base to calculate the Shannon-Wiener diversity index. The Wieprz River valley has the character of a floodplain. In its middle reaches, communities of the Molinio- Arrhenatheretea class accounted for nearly 75% of all plant communities in grasslands. Herbaceous communities were represented by associations from the Filipendulion alliance. The greatest diversity (H’ = 3.4) was characteristic for vegetation of the Valeriano-Filipenduletum association. It formed small patches in abandoned meadows. Small patches of plants from the Lythro-Filipenduletum ulmariae association, having a slightly smaller floristic diversity (H’ = 3.0) were found on abandoned meadows located in highly silted and poor organic soils. Characteristic species of herbaceous communities (Filipendula ulmaria, Valeriana officinalis and Lythrum salicaria) occurred also in the sward of abandoned thistle meadows. Typical thistle meadows (Cirsietum rivularis), with the predominance of Cirsium rivulare developed in land depressions, not far from the Wieprz River, in the vicinity of abandoned drainage ditches and along the edges of the valley. However, the total abandonment of these meadows leads to changes in floristic composition of the sward and to succession towards herbaceous communities.

Ayung river is the longest river in Bali. The middle part of the river is frequently utilized as rafting for tourism, such as in Bongkasa Pertiwi Village, Abiansemal District, Badung Regency – Bali. To preserve the river’s ecological function, the information of riparian vegetation as the dynamic component in river is highly required. This research aimed to study the structure of riparian vegetation in Bongkasa Pertiwi Village. The plot method was used and the study site was divided into three stations. Each station was composed by three replications with four plot variations: trees (20 x 20 m), poles (10 x 10 m), saplings (5 x 5), and herbs-shrubs (2 x 2 m). The data was analysed using vegetation analysis that completed with Importance Value (IV), Shannon-Wiener Diversity Index (H’), Index of Dominancy (C), and Index of Evenness (E). This study found that the structure of riparian vegetation in Bongkasa Pertiwi Village was in good condition which was indicated by the high abundance of local tree species. The floristic composition of riparian vegetation comprised by 18 species of trees, 18 species of poles, 21 species of saplings, and 29 species of herbs and shrubs. Cocos nucifera, Pterospermum javanicum, Bischofia javanica, Cananga odorata, Elaeocarpus serratus, Artocarpus heterophyllus, Coffea canephora, and Nephelium lappaceum were the species with the highest Importance Value (IV). The floor vegetation in form of herbs and shrubs was dominated by Sphaegneticola trilobata, Oplismenus burmanni, and Diplazium esculentum. Based on the Diversity Index (H’), Index of Dominancy (C), and Index of Evenness (E), diversity of riparian vegetation in Bongkasa Pertiwi Village was classified as medium category, without any dominated species, and the vegetation composition was equivalent.

Abstract. Susilowati A, Elfiati D, Rachmat HH, Yulita KS, Hadi AN, Kusuma YS, Batu SAL. 2020. Vegetation structure and floristic composition of tree species in the habitat of Scaphium macropodum in Gunung Leuser National Park, Sumatra, Indonesia. Biodiversitas 21: 3025-3033. Scaphium macropodum (Miq.) Beumee Ex K Heyne is a member of Malvaceae tree species and globally recognized as malva nut and locally known as ‘kembang semangkok’, ‘tempayang’, ‘merpayang’ or ‘kepayang’. The nut of S. macropodum has many benefits for medicinal purposes, yet destructive extraction of this tree species has led them to extinction. Among its natural distribution in Indonesia, North Sumatra Province, Indonesia is known as its original range, but there is limited information about the existence of this species. This study aimed to determine the vegetation structure of some tree species in the habitat of S. macropodum in Sikundur, Gunung Leuser National Park, Sumatra, Indonesia. Purposive sampling technique was employed by creating line transect at some forest areas where the population of S. macropodum is known to grow naturally. Four line transects with each transect consisting of five plots with nested plots within were established to record data at four growth stages, resulting in 80 plots in total. The results showed that the Important Value Index (IVI) of S. macropodum within the floristic community at the studied area was 21.98, 13.85, 27.30, and 39.60 for tree, pole, sapling, and seedlings stages, respectively. The Shannon-Wiener Diversity Index (H) were 3.80, 3.70, 3.06 and 2.45, Index of evenness (E) are 0.94, 0.92, 0.86, 0.77 and the Index of Richness (R) are 11.76, 10.73, 6.59, 4.10 for tree, pole, sapling, and seedlings stages. This result suggests that the natural population of S. macropodum in Sikundur forest was still in good condition at all stages from tree to seedling.

ABSTRACT This study was conducted in a forest under restoration process, which belongs to the company Holcim Brasil S/A, in the municipality of Barroso, state of Minas Gerais (21º00'to 22º00'S and 43º00' to 44º00'W), where 40 plots (2 x 2 m) were set, spaced at 10 m, forming eight strata parallel to the watercourse present in the area. Floristic composition and natural regeneration stratum were characterized, and the formed strata allowed evaluating whether the riparian vegetation and watercourse influence on the local regeneration. It was found 162 individuals of 13 families, 18 genera and 22 species, and 10,125 individuals/ha were estimated. Successional classes from pioneer and early secondary and zoochory dispersion syndrome prevailed among species and individuals. The watercourse and riparian vegetation did not exercise significant influence (p> 0.05) on the number of species and regenerating individuals among the different strata of the forest. The diversity index of Shannon-Wiener (H') and equability of Pielou (J') were 2.691 and 0.870, respectively. The species Psidium guajava and Myrtaceae families presented the highest VI (value of importance). Natural regeneration analysis showed the low floristic diversity in the area, suggesting that corrective management actions should be adopted.

Abstract The aim of the study was to show the impact of the peat extraction on the development and properties of organic soils and plant habitat in post-extraction sites. The study was conducted in the complex of the Trzcińskie Mokradła Peatlands (Sudetes Mts., SW Poland). The Trzcińskie Mokradła Peatlands began to form in Preboreal (10960–9330 ±50BP) so that they are one of the oldest peatlands in the Sudetes. We analyzed 8 soil profiles (42 samples). Peat forming process there is still active in the moderate or strong degree (PtII-PtIII). The floristic composition of the studied areas was typical of transition peatlands. Successive dry and moist periods were observed in the developed of organic soils. The time gaps in peat profiles covering hundreds of years prove their extraction in the past.

In The Wild

The study objective was to assess the floristic composition of pastures for wild animals (fallow deer, Manchurian deer and mouflons) at Przytoczno, pastures for horses at Białka, and cow pastures belonging to the Land Community in Tarnogóra. We analyzed the floristic composition of the pastures under study in the growing seasons of 2011 and 2012, carried out 32 phytosociological relevés in the wild animal pastures, 32 in the horse pastures, and 38 in the cow pastures, using the Braun-Blanquet method. We determined the species diversity of the pastures based on the percentage share of species from the botanical families distinguished, the total number of species, and the Shannon–Wiener and Simpson diversity index. Our floristic surveys indicated that the greatest species diversity occurred in the horse pastures, while it was lower in the wild animal and cow pastures. The Shannon–Wiener diversity index for the sward of the pastures grazed by horses was higher (H' = 5.04) than for those grazed by wild animals (H' = 4.32) and cows (H' = 3.53). The Simpson index of species diversity in a community was higher for the pastures grazed by horses (S = 0.96) than for those grazed by wild animals (S = 0.95) and cows (S = 0.90).

Phytosociological Relevés

The paper describes the floristic diversity and specifies its use value in terms of feeding preferences of konik polski horses and their consumption of permanent grassland in a section of the Wieprz river valley in Roztocze National Park. The flora assessment was conducted by analyzing 79 phytosociological relevés using the Braun-Blanquet method. The results of phytosociological surveys made it possible to distinguish 7 complexes in the Phragmitetea class, 5 complexes and 1 plant community in the Molinio-Arrhenatheretea class, and 1 complex in the Nardo-Callunetea class. Natural values of the examined associations were described based on the total and average number of species in a phytosociological relevé, the Shannon-Wiener index, and the phytosociological structure of plant communities. The use value of dry weight of the analyzed meadows and pastures was estimated by means of the use value number (UVN) and taking into account the and yield size. The phytocoenoses identified in the meadows in the section of the Wieprz river valley under study exhibited high natural values (H’ = 3.20–4.62). The dry weight yields of the examined communities varied (from 1.32 to 5.37 t ha–1), but their sward usually had poor and very poor use value (UVN = from –0.55 to 5.8). Furthermore, it should be noted that the sward of wet meadows is readily consumed by the grazing animals, which contributes to the improvement of the natural and use value of meadows.

Abstract Aims Caryota obtusa of Arecaceae is a fascinating palm tree native to southwestern China, India, Myanmar, Thailand, Laos, and Vietnam. It is an economically important and threatened species and appears as a canopy dominant in some karst areas in Yunnan. We aim to clarify the forest structure, species diversity, population status and regeneration dynamics of C. obtusa in the karst forest ecosystem of Yunnan, China. Methods We established 56 vegetation plots dominated by C. obtusa in 10 counties of southern Yunnan. As based on the plot data, we analyzed the community stratification, floristic composition, and C. obtusa’s population structure. We used questionnaires to interview local people and recorded the human activity history on C. obtusa-dominated forests. Important findings: C. obtusa palm forests were distributed on limestone mountain slopes and gullies. There were seven forest community types. The stratification of each community included arborous layer, shrub layer and understory. The communities had rich species composition. For all the plots as a whole of each community type, Shannon-Wiener diversity index of either woody or herbaceous species ranged from 2.1-3.8. The DBH-class frequency distribution of C. obtusa was a multimodal type. The regeneration was sporadic and depended on intermediate natural disturbances. In current population structure, number of C. obtusa trees with small DBHs was consisted mainly of the forest communities with no or a slight degree of human disturbances. Intensive human activities terribly hindered C. obtusa’s recruitment, followed by medium intensity of human activities.

Phytosociological Study

The increasing importance of secondary forests all over the world alerts us to the urgent need to understand the biophysical and social underlying factors that affect its regeneration after the abandonment of agricultural practices and natural disturbances. In the state of Amapá, studies related to the structure of secondary forests are still scarce. Therefore, this article aims to characterize the floristic composition and structure in two stretches of secondary forest in the eastern Amazon, state of Amapá. For the floristic and phytosociological study of tree species, 10 plots of 10 x 100 m (1.0 ha) were established: five plots in the community of São Francisco do Iratapuru and five plots in the community of Santo Antônio waterfall, totaling half a hectare (0,5 ha) in each area. In all plots, subjects with diameter at breast height (DBH) ≥ 5 cm were considered. In total, 1,183 subjects were sampled in the two stretches of forest. In stretch 01, 565 subjects belonging to 74 species, 55 genera and 33 families were recorded. In stretch 02, 618 subjects belonging to 26 species, 23 genera and 15 families were recorded. The Shannon diversity index (H'), estimated for stretch 1, was 3.52; and for stretch 2 (2.23). The two studied stretches, despite being registered at the same age, showed significant difference in the species richness, which is the major factor for diversity differences, resulting in low similarity between the studied forests.

This paper presents the results of a study on the vegetation of the thermally active postmining heap “Ruda” in Zabrze (Poland). The aims of the study were: (i) to show the differentiation of the vegetation that has developed as a result of the thermal activity, and (ii) to determine the effect of thermal activity of the spoil heap on species richness and species diversity of the vegetation. Twelve plant communities were recorded on the heap. Thermal activity has a statistically significant impact on species richness (Z = 2.13, p = 0.03) and species diversity (Z = 2.29, p = 0.02). The species composition of plant communities reflects the habitat conditions, which are conditioned by thermal activity. As the distance from a zone with increased thermal activity increases, the degree of the spontaneous succession of vegetation and the complexity of the vegetation increase. Moreover, the share of annual species and kenophytes decreases in favor of perennial plants and apophytes. The number of plant communities (from four to eight), their species richness (number of species from 15 to 22) and species diversity (Shannon–Wiener diversity index from 1.81 to 2.19) also increase. A DCA analysis showed an increase in the shading, humidity and pH of the substrate, and the thickness of the dead organic matter within the gradient of the thermal activity.
