Abstract. Wiryono Mersyah R, Tarantona M. 2020. Flora of Danau Dusun Besar conservation forest in Bengkulu Province, Indonesia. Biodiversitas 21: 5640-5649. Few studies on flora of freshwater swamp forest in Sumatra have been published and accessible online. This study aimed to assess the composition and diversity of plant species and to describe the dominant species in conservation forest of Danau Dusun Besar Nature Reserve and Nature Tourism Park in Bengkulu which consists mostly of freshwater swamp forests and a lake. Data collection was done using a combination of quantitative methods with systematic plots and qualitative methods through observation. The quantitative data were analyzed to determine indexes of diversity, evenness and importance value. This study recorded 23 species of trees with diversity index (H?) and evenness index (E) of 0.29 and 0.09, respectively, and recorded 136 species of shrubs and herbs with H? and E values of 3.68 and 0.75, respectively. The most dominant species of trees was Alstonia spatulata, of shrubs and herbs Stenochlaena palustris. The small diameter class of trees and the covering of trees with climbers indicated that the large trees had been cut. We recommend further studies with more and better-located plots to get better data on the vegetation composition and structure, including the invasion of alien species Ludwigia peruviana and the effect of climbers on trees.

Abstract. Wiryono, Kristiansen P, Bruyn LLD, Saprinurdin, Nurliana S. 2023. Ecosystem services provided by agroforestry home gardens in Bengkulu, Indonesia: Smallholder utilization, biodiversity conservation, and carbon storage. Biodiversitas 24: 2657-2665. Agroforestry system provides ecosystem services such as conserving biodiversity and providing smallholder farmers with food and other daily needs. It can also generate income for the owners. This study was conducted in 105 home gardens of four villages in Bengkulu Province, Indonesia, to analyze tree species diversity and composition, uses, and potential carbon storage in the agroforestry system of home gardens. Tree data were collected on individual trees from 200 plots (10×10 m). Home garden owners were interviewed on the uses of each tree species. The species richness of trees in each village ranged from 18 to 36, with a total of 57 species (29 introduced and 28 native) for four villages. Most trees (30 species) provided food. The above-ground carbon storage of trees ranged from 29 Mg ha-1to 127 Mg ha-1, with an average of 87 Mg ha-1. This study found that the agroforestry system in home gardens serves some ecosystem services, i.e., providing food, medicines, and other daily needs, conserving plant species and the habitat they provide, and storing carbon. These ecosystem services help villagers build resilience to changing environmental and socio-economic conditions.
