Abstract

Indonesia merupakan negara kepuluauan seluas sekitar 9 juta km2 yang terletak diantara dua samudra dan dua benua dengan jumlah pulau sekitar 17.500 buah yang panjang garis pantainya sekitar 95.181 km. Kondisi geografis tersebut menyebabkan negara Indonesia menjadi suatu negara megabiodiversitas walaupun luasnya hanya sekitar 1,3% dari luas bumi. Dalam dunia tumbuhan, flora di wilayah Indonesia termasuk bagian dari flora dari Malesiana yang diperkirakan memiliki sekitar 25% dari spesies tumbuhan berbunga yang ada di dunia yang menempati urutan negara terbesar ketujuh dengan jumlah spesies mencapai 20.000 spesies, 40%-nya merupakan tumbuhan endemik atau asli Indonesia. Negara Indonesia termasuk negara dengan tingkat keterancaman dan kepunahan spesies tumbuhan tertinggi di dunia. Saat ini tercatat sekitar 240 spesies tanaman dinyatakan langka, diantaranya banyak yang merupakan spesies tanaman budidaya. Selain itu, sekitar 36 spesies pohon di Indonesia dinyatakan terancam punah, termasuk kayu ulin di Kalimantan Selatan, sawo kecik di Jawa Timur, Bali Barat, dan Sumbawa, kayu hitam di Sulawesi, dan kayu pandak di Jawa serta ada sekitar 58 spesies tumbuhan yang berstatus dilindungi.Keywords: keanekaragaman hayati flora, megabiodiversitas, tingkat kepunahan, tumbuhan dilindungi, tumbuhan langka

Abstract

Sheoak (Casuarina equisetifolia L) is a species of monotypic taxa that has grown naturally in coastal Bengkulu Province. However, the various dynamics occurring in the coastal areas have disrupted the habitat of this species, affecting the structure and composi-tion of the vegetation. This research aims to analyze the structure and composition of vegetation in sheoak habitat in three conser-vation areas. The vegetation data was collected by line transect plot method. The analysis shows that sheoak stands form an invert-ed curve J in three conservation areas although they were not perfect due to the low density of poles which can be caused by dis-turbances that come from nature and human activity. Vegetation composition in sheoak habitat was composed by 36 species of 27 plant families consisting of shrubs and trees. Sheoak dominated the three areas only at the rate of tree growth while the growth rates of seedlings, saplings and poles were dominated by nyamplung (Calophyllum inophyllum) so the dominance of sheoak can be replaced with nyamplung. Sheoak also supported better habitat for other plant species to grow that showed diversity index value 1.4 to 1.9.

Abstract

In the context of conservation, the government of Timor-Leste and its partners work together to implement an agroforestry program to address the problem of forest loss which continues to be graded every year. This study aimed to estimate the level of plant species diversity and the potential benefits of agroforestry for the Batara Village community. Data collection was carried out on agroforestry land owned by farmers in Batara Village from December 2021 to January 2022 and data collection using the single plot method and census method, namely 10m x 10m seedlings, 40m x 40m sapling, 60m x 60m pole and 113,14m x 113,14m tree. Data for plant diversity can be analyzed using the margalef index, shannon wiener, and evenness, and the potential benefits of agroforestry using descriptive analysis. Based on the results of research on the diversity of plant species in agroforestry land in Batara village, 33 species of seedling and understorey, sapling level 19 species, pole level 17 species, and tree level 15 species and overall found 42 species of plants with 25 families and the results of descriptive analysis of respondents' interviews show that agroforestry can contribute from an economic point of view by 54.28%, from an ecological perspective to 32.95%, from a social perspective to 24.18% and from a cultural perspective to 6.1%.
