Abstract. Master J, Qayim I, Setiadi D, Santoso N. 2020. Autecology of Melastoma malabathricum, an invasive species in the Way Kambas National Park, Indonesia. Biodiversitas 21: 2303-2310. Melastoma malabathricum has become one of the invasive plants in the Way Kambas National Park (WKNP), Lampung, Indonesia. This plant is feared to be a problem in efforts to conserve biodiversity in the WKNP area. Therefore, this study aimed to analyze the factors causing the invasion of these plants. The vegetation analysis plot was placed on three types of habitats in the study location, namely, forests, swamps, and invaded swamps, then measurements and records of vegetation data and abiotic factors were recorded in each plot. The results reveal that M. malabathricum dominates swamp habitat and negatively associated with trees, which can provide canopy. Abiotic factors, such as canopy cover, water level, and soil fertility, become supporting factors for the invasion. In addition, climate change, which is causing drought also contributes to the invasion of M. malabathricum at the WKNP.

 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.

The Impact

Despite increasing evidence indicating that invasive species are harming ecological systems and processes, impacts of multiple invasions, and the linkages between these events and changes in vegetation and soil are inadequately documented and remain poorly understood. Addressing multiple invasions would help to highlight high priority invaders and would aid in designing more effective control strategies, contributing to environmental restoration and sustainability. In this work, we tested the impact of three concurring invasive plant species, Amorpha fruticosa, Fraxinus pennsylvanica and Acer negundo, on soil conditions and native plant diversity. The research was conducted in riparian ecosystem and included the following treatments: (1) co-occurrence of the three invasive plant species, (2) occurrence of a single invasive species, and (3) control, i.e., absence of invasive species. Our findings revealed that the impact of invasive plants on soil properties and native plant diversity is magnified by their co-occurrence. Soil in mixed plots (those populated with all three invaders) contained much higher levels of nitrifying bacteria (NB), organic matter (Om), nitrogen (N), and carbon (C) as well as lower carbon to nitrogen ratio (C:N) levels, compared to single species invaded plots and control plots. Mixed plots were also characterized by reduced native plant diversity compared to single species invaded and control plots. Differences in soil conditions and native plant diversity revealed the interactive potential of invasive plants in depleting biodiversity, and thus in affecting ecological and biogeochemical processes. Our results highlight the need to study the impact of multispecies invasion and suggest that sites in riparian areas affected by co-occurring invaders, should be prioritized for ecosystem restoration.

<p>Threats on biodiversity in a conservation area can originated from outside or inside the area.  One of the outsiders that rarely noticeable is invasion of exotic species, which usually alters the stability of natural processes within the area. Wasur National Park has some wetland ecosystems that overcome the issues of deterioration in function and benefits due to exotic plant invasion in recent days. This research was carried out to determine priority species that need immediately managements in Wasur National Park.  Field survey and inventory followed by scoring and evaluation methods using Weed Risk Assessment by Exotic Species Ranking System were taken in this research to obtain the priority species. The scoring and ranking steps placed encountered invasive plant species into four categories of management priority based on Significance of Impact and the Feasibility of Control. The result identified 49 species of invasive plants from three wetlands in Wasur National Park, which 75% (or 36 species) of them are species of Priority 3 (lesser threat and easy to control), 4 species of Priority 4 (lesser threat – hard to control) and at least 9 species of Priority 2 (serious threat-hard to control).  Priority 2 species consist of <em>Carex</em> sp., <em>Eleocharis indica</em> (Lour.) Druce, <em>Hanguana malayana</em> (Jack.) Merr., <em>Imperata cylindrica</em> (L.) Beauv., <em>Ludwigia oktovalvis</em> (Jacq.) Raven, <em>Melaleuca cajuputi</em>  Powell, <em>M. leucadendron</em> (Linn.), <em>Paspalum</em> <em>conjugatum</em> P. J.
