“…The criteria used were: The importance value index (IVI) for herbs, shrubs, seedlings, and saplings were calculated by summing relative density and relative frequency. IVI of poles and trees were calculated by summing the relative density, relative frequency, and relative dominance (Roemantyo et al, 2012;Suryawan et al, 2015).…”

The eruption in 2010 of Merapi Mount changed the diversity of plant species. The objective of this research was to investigate the diversity of plant species on Mount Merapi National Park (MMNP). The sampling area was divided into three different levels of damage (heavy, medium, and mirror). The research was conducted by using line-transect and quadrat method. We were conducted using line-transect and quadrat method. The research showed that Acacia decurrens has the highest Important Value Index (IVI) at the heavy damage area of Cangkringan Resort (CR) and Kemalang Resort (KR) as well as in mirror damage area of Selo Resort (SR). The most important species at medium damage area of Dukun Resort (DR) were Albizia lopantha and Pinus merkusii. The pioneer species at Non-Cover Area (NCA) among others were Trema cannabina, Pityrogramma calomelanos, Imperata cylindrical, Buddleja asiatica, Anaphalis javanica. Eupatorium riparium were the most important species of herb in all four locations based on SIMPER, but it was not dominant in NCA. The homogeneity of plant in Cangkringan Resort and Selo Resort (C < D < E) were normally distributed, whereas NCA, DR, and KR (E ≥ D) were homogeneous. Analysis of non-metric multidimensional scaling and value of ANOSIM (RANOSIM =0.69; p = 0.0001) demonstrated that all site locations have significance differences. This research was not only focusing on survey of vegetation diversity, but also frequency class distribution. Through this study of frequency of species provides a database for conservation biodiversity and restoration program.

“…deccurens is a species that has high adaptability and is fast growing in post-eruption areas. According to (Suryawan, 2015), A. deccurens is considered as one of the invasive alien species in the Mount Merapi National Park area. This type can grow as a pioneer, fast, and dominant in the area affected by the eruption of Mount Merapi.…”

Mount Merapi National Park (MMNP) is a natural con-servation area with the main function of preserving the diversity of plants, animals and their ecosystems. In 2010, Mount Merapi suffered a large eruption which caused damage to the forest ecosystem inside. One of the locations that suffered severe damage was at Cangkrin-gan Resort. After the eruption, the affected vegetation began to grow again. The purpose of this study is to monitor and determine the di-versity of secondary forest plants in the MMNP area. The method used was a method of path and use a point-intercept transect as the sam-pling unit. The results showed that after the eruption, the Acacia de-curens dominated at each level starting from sapling, poles and trees. Based on the results of the study showed that the eruption of Mount Merapi that occurred in 2010 resulted in a change in vegetation struc-ture in the area with the Shannon-Weiner diversity index which is still low, amounting to 1.86 for seedling, 1.32 for the sapling and 0.22 for poles. At the tree level 100% is still dominated by Acacia decurens.

Acacia nilotica which is a plants of the genus Acacia which is known as one of the invasive genera. A. nilotica is very invasive due to several advantages it has such as very large seed production, seed dispersal far enough by wildlife, young plants to grow very fast and are resistant to drought and fire. Some invasive acacia species can act as nurse plants for native plants, which increases the photosynthetic efficiency of native plants, and protects native species from extreme temperatures. Therefore, it is important to know the chance of recolonizing native plants in areas that are invaded by foreign species, by looking at the performance of plants seedlings under A. nilotica stands. This study aims to determine the potential of A. nilotica invasive plants as nurse plants for local plants in East Timor. The stages in this research are the preparation of tools and materials, seeding of target species, selection of A. nilotica stands as a nurse plants, selection of healthy target species seedlings to be planted, planting of target species seedlings under A. nilotica stands, observing survival ability and species growth target. An analysis of the survival ability of the seedlings was carried out using the Kaplan-Meier survival curve. The results of this study are the angsana seedlings and kabesak in this study experienced many deaths, external factors such as high-temperature factors due to the long dry season suspected to be the cause. A. nilotica shade does not affect the survival of the angsana and kabesak seedlings, allelopathy produced by A. nilotica plants accompanied by a drought in a long period of time causes the plants is unable to act as nurse plants for kabesak and angsana plants.
