Abstract

Penelitian ini bertujuan untuk mengetahui kondisi hutan lahan kering sekunder (blok tahun 2016) dan hutan lahan kering primer (blok tahun 2018) yang didasarkan pada struktur dan komposisi jenis tegakan tingkat semai, pancang, tiang dan pohon. Hasil penelitian menunjukkan bahwa struktur hutan seperti huruf J terbalik yang berarti kondisi struktur hutan primer dan sekunder normal. Jumlah jenis yang ditemukan dalam petak ukur di blok tahun 2016 adalah 54 dan di blok 2018 adalah 50 jenis. Nilai indek keragaman jenis (H’) pada blok tahun 2016 dan 2018 berkisar antara 2,7-3,35 (tinggi), nilai indeks kemerataan jenis antara 0,83-0,93 (tinggi) dan nilai indeks kekayaan jenis antara 5,10-7,73 (tinggi) untuk semua tingkat pertumbuhan. Berdasarkan nilai-nilai tersebut dapat disimpulkan bahwa kondisi hutan baik pada hutan sekunder maupun hutan primer tergolong baik dan ideal.

Abstract

This study aims to determine the species diversity and distribution pattern of medicinal plants in the peat swamp forest at ​​Sebangau Hulu Resort, Sebangau National Park, Central Kalimantan. Based on the results of the study, there were 19 types of medicinal plants in the peat swamp forest at the Sebangau Hulu Resort, which include to 15 families. Medicinal plants at the seedling and sapling level were dominated by Tatumbu (Syzygium sp.), and Jinjit (Calophyllum soulatri), while at the pole and tree level it was dominated by Piais (Nephelium lapaceun L.), Beside these types,  Latak Manuk (Ctenolophon parvifolius Oliver) was a species that also dominant at the stake and pile level. Species diversity of medicinal plant  includes low to moderate classification, species richness includes low classification, and evenness includes high classification. The distribution pattern of medicinal plants at the seedling and sapling level has an aggregated pattern, while at the pole and tree level it has a random pattern.

Abstract

The study aims to determine the composition and diversity of species in several covers, namely: swamp, secondary swamp forest, swamp shrubs and swamps in the Sebangau National Park area.  The number of plant species found in the three forest communities in the study site was 62 species. The most dominant plant species at almost all growth levels was Tumih (Combretocarpus rotundatus), followed by guava (Syzgium sp.), and Tamehas (Memecylon costatum). Meranti (Shorea sp.) and piais (Nephelium lappaceum L.) species were dominant in the secondary swamp forest community.  The species diversity index with a range of1.24-3.32 and species richness index with a range of 2.63-6.42 in the three types of land cover is classified as medium to high.  The evenness index is classified as high for all growth stages, except for the seedling level in the swamp shrub community which is classified as medium.
