The structure and diversity of vegetation treelets of tropical mountain forest on mount Bawakaraeng

Abstract The study about the diversity and structure of treelet vegetation in three slope areas on the mountainous forest of mount Bawakaraeng, Regency of Gowa, Province of South Sulawesi had been done. There were 17 species of treelets throughout the study area, from 13 families and 16 genera. The Asteraceae family has the highest number of species with 3 species, followed by Fabaceae and Solanaceae which each has 2 species. Pteridium aquilinum, Chromolaena odorata, Breynia oblongifolia, and Pogostemon cablin are the species with the highest important value index. The number of treelet species ranges from 15-16. Treelet species were mostly found in the flat slope area. The Shannon-Wiener diversity index (H’) ranges from 2,033-2,161 and was found to be highest on steep slopes and lowest on flat slopes. The H’ has the same tendency as Simpson’s Diversity Index and Evenness Index of Pielou (E) and reverse relationship with Simpson’s Dominance Index.

Biogeographic Provinces

In Central Mexico converge three biogeographic provinces: Altiplano sur, Sierra Madre Occidental and Costa del Pacífico. Each one of them is composed by different plant communities: Thorn Forest, Temperate Mountain Forest and Dry Tropical Forest respectively. Our objective is to show, through phytoecological analysis, the species richness, diversity and the structure of the plant communities from the Temperate Mountain Forest and from the Tropical Dry Forest. In the Temperate Mountain Forest, 50 forest species were recorded, with a Shannon Wiener diversity index H´ = 1.63 on altitudes from 2400 to 2600 m. The Whittaker β index is Bw = 7.22. In the tropical dry forest, we identified 79 plants species with a mean diversity index H´ = 3.49 on altitudes from 1951 to 2100 m. In this ecosystem the Bw index is 8.12. This study offers important information for the establishment of management practices, considering the protection status from the areas in which this vegetation type is distributed.

Pteridophyte richness and diversity in Kudremukh National Park (KNP) was assessed using qualitative and quantitative diversity indexing methods, along with the geographic spatial distribution of the extant pteridophyte flora. The field research design employed a stratified random sampling method and was conducted in two phases. Phase 1 included the survey, identification and distribution of the pteridophyte flora and Phase 2 was to study the diversity of the extant pteridophytes throughout the KNP using seven transects. The region exhibited rich and highly diverse (Shannon-Wiener Diversity Index of 3.38), non-homogenous (compared to normal Raunkiaer’s frequency curve) stand of 46 different unevenly (evenness index 0.64) distributed pteridophyte flora. The study region was dominated by two unambiguous pteridophyte species of weedy nature (Pteridium aquilinum and Dicranopteris linearis), with a high Simpson's dominance index of 0.96. The study reports eight endemic, two rare, five at risk and seven vulnerable and near-threatened IUCN listed pteridophyte species in the study region. The quantitative diversity indices i.e. frequency, density, abundance, relative abundance and important value index of each extant pteridophyte is calculated. The study also noted that some endemic species such as Osmunda huegeliana and Cyathea nilgirensis present in KNP needed immediate conservation efforts. This study gives an extensive report on the extant pteridophyte flora of KNP and will help future taxonomic surveys and research, as well as conservation and sustenance measures.

AbstrakRegenerasi dan restorasi hutan rawa gambut merupakan hal yang sulit terjadi secara alami. Restorasi ekosistem bukan hanya membuat tegakan baru tetapi juga harus berbasis keanekaragaman hayati lokal untuk membuat peluang berhasilnya menjadi lebih tinggi. Tujuan dari penelitian ini adalah mendapatkan data mengenai potensi permudaan alam dalam rangka regenerasi dan restorasi lahan gambut di Tahura Orang Kayo Hitam pasca kebakaran hutan. Penelitian ini dilaksanakan selama 7 bulan, yaitu dari Maret sampai Oktober 2019 di Tahura Orang Kayo Hitam, Herbarium Fakultas Kehutanan Universitas Jambi dan Laboratorium Silvikultur dan Manajemen Universitas Jambi. Metode yang digunakan adalah kombinasi transek dengan garis berpetak. Hasil penelitian menunjukkan bahwa terdapat 29 jenis anakan alam yang tergabung dalam 19 famili tumbuhan. Jenis yang paling dominan adalah arang-arang (Diospyros mangiayi) diikuti oleh meranti bunga (Shorea teijsmanniana) dengan Indeks Nilai Penting (INP) berturut-turut sebesar 20,10% dan 19,33%. Indeks kekayaan Margaleff D= 4,88, indeks keanekaragaman Shannon-Wiener H’= 2,96 dan indeks Evennes E= 0,88. Nilai dari semua indeks menunjukkan kondisi permudaan alam yang cukup baik di Tahura Orang Kayo Hitam. Hal ini diharapkan mampu menjadi pendorong dalam restorasi ekosistem yang berbasis jenis lokal untuk masa depan hutan rawa gambut. Abstract Regeneration and restoration of peat swamp forests is a difficult thing to happen naturally. Ecosystem regeneration and restoration not only create new stands but must also be based on local biodiversity to make the chances of success even higher. The purpose of this study is to obtain data and information about the potential of seedlings for the regeneration and restoration of peatlands in Tahura Orang Kayo Hitam after forest fires. This research was conducted for 7 months from March to October 2019 with locations in Orang Kayo Hitam Tahura, Herbarium of the Faculty of Forestry at the University of Jambi and the University of Jambi's Silviculture and Management Laboratory. The most dominant types are arang-arang (Diospyros mangiayi) followed by meranti bunga (Shorea teijsmanniana) with Important Value Index (INP) respectively of 20.10% and 19.33%. Margaleff's Wealth Index D= 4, 88. The Shannon-Wiener Diversity Index shows a value of H 'of 2.96 and the Index of Evennes indicates a value of E= 0.88. The values obtained from all of the measured indices indicate the condition of natural regeneration which is quite good in Tahura Orang Kayo Hitam. This is expected to lead to local species-based ecosystem restoration for the future of peat swamp forests.

The methodological approach and methodical problems of evaluation and mapping of biodiversity of mountain forest territory in Primorsky Krai (south of the Russian Far East) are considered. The complex evaluation of biodiversity is presented according to the scheme: (ecotopical environments → vegetation → animal population) ← fire-danger. It is proposed to compile the maps of ecotopical diversity on a basis of diversity index and contrast of relief characteristics, and the maps of geobotanical and zoological diversity — on a basis of spatial extrapolation of indexes relating biota to environmental conditions. The examples of construction of appropriate maps are given for Primorye Region.
