Abstract

The presence of invasive alien plant species has been known to cause various negative impacts on ecosystems in theinvaded conservation area. This research aims to identify diversity and distribution pattern of invasive alien plantsspecies in Sempu Island Nature Reserve, and to determine the most influential environmental factors to theirdispersion. The methods used were the combination of quantitative vegetation analysis and rapid assessmenttechnique followed by the principal component analysis. As many as 10 invasive alien plants species (belonging to 7families) have been identified within this conservation area, e.g., Pistia stratoites, Ageratum mexicanum, Vernoniacinerea, Cyperus rotundus, Passiflora foetida, Centotheca lappacea, Eleusine indica, Imperata cylindrica, Hedyotiscorymbosa, and Lantana camara. All invasive alien plant species found in the sampling plots had a clumpeddistribution pattern. The most influential environmental factors to the invasive alien plants dispersion were landslope and distance from shoreline.Keywords: distribution pattern, environmental factors, invasive alien plants, Sempu Island Nature Reserve

Abstract

ABSTRACTSuccession dynamics (as a complex interaction and relationship between environment and species) is a crucial ecological process for managing and restoring habitats and ecosystems. This research was conducted at several locations based on the damage levels occurred due to the 2010 eruption of Mount Merapi: heavily damaged site was chosen at the Cangkringan Resort (consisting of both open and covered areas) and the Kemalang Resort, medium damage site was located at the Dukun Resort, and minor damage/relatively intact site was situated at the Selo Resort. A total of 135 plant species belonging to 64 families were recorded from all locations during the study. The Mount Merapi eruption occurred in 2010 had significantly impacted on the floristic community structure and condition. Canonical Correspondence Analysis (CCA) was used to analyze the relationships between environmental variables and the existing plant species conditions. The results indicated that different abiotic environment conditions (variables) significantly influenced species compositions and conditions. The covered area (?= 0:49; p= 0.002; F= 10:35) and the elevation factor (?= 0:32; p= 0.002; F= 7:08) provided the highest impact on vegetation conditions. Meanwhile, the relationships and correlations between edaphic factors and floristic community conditions varied from site to site.Key words: Abiotic environment, floristic community, succession, Mount Merapi, restoration

Abstract

Mangifera casturi Kosterm. (Anacardiaceae) merupakan spesies yang dinyatakan punah di alam liar. Spesies ini endemikdi pulau Kalimantan. Saat ini, Mangifera casturi telah dibudidayakan di luar sebaran alaminya, terutama diKabupaten Indragiri Hilir Provinsi Riau, Sumatera. Penelitian dilakukan di dua kecamatan di Kabupaten IndragiriHilir, yaitu Kecamatan Gaung Anak Serka (GAS) dan Kecamatan Gaung. Sebanyak 1.315 individu M. casturiditemukan dalam penelitian yang dilakukan. Keberhasilan konservasi ex situ M. casturi di daerah ini didukung olehsetidaknya tiga stimulus: alami, manfaat, dan stimulus religius. Namun faktor internal dan eksternal milik masyarakatsetempat juga mempengaruhi secara signifikan. Di Kecamatan GAS, konservasi ex situ M. casturi terutamadidukung oleh stimulus manfaat sementara di Kecamatan Gaung upaya konservasi ex situ didukung oleh stimulusreligius. Analisa komponen utama dilakukan untuk menentukan kemungkinan hubungan antara konservasi ex situM. casturi dan variabel pendukung dalam masyarakat. Di Kecamatan GAS, yang upaya konservasi ex situ M. casturisecara signifikan didukung oleh ukuran populasi, panen dan pemasaran serta kegiatan pra tanam. Di KecamatanGaung, konservasi ex situ dari M. casturi tidak hanya didukung oleh ukuran populasi, panen dan kegiatan pasar, tetapijuga oleh kegiatan pra tanam, status dan luas lahan.Kata Kunci: Indragiri Hilir, Konservasi ex situ, Mangifera casturi, Punah di alam liar

Abstract

ABSTRACTThe growth and regeneration of langkap in natural habitat is very fast and has invasive tendencies. The aim of study was to analyze the population and population structure of langkap in Leuweung Sancang Nature Reserve, and build spatial models of habitat suitability langkap in Leuweung Sancang Nature Reserve. Data were collected using a sampling method with a number of plots along the transect line. Langkap has become the dominant species in Leuweung Sancang Nature Reserve on saplings and pole with population structure shows an normally structure population. Analysis of spatial modelling on habitat suitability of langkap through binary logistic regression with independent variables in the form of the Forest Canopy Density (FCD), slope, distance from the river and Normalized Difference Moisture Index (NDMI) has been able to predict habitat suitability of langkap in Leuweung Sancang Nature Reserve, i.e. 61,10% of the Leuweung Sancang Nature Reserve suitable as habitat langkap and 38,90% of the Leuweung Sancang Nature Reserve is not suitable as habitat langkap. Keywords: Langkap, Arenga obtusifolia, habitat suitability, spatial modeling, Leuweung Sancang Nature Reserve.
