Ekosistem mangrove terdapat di seluruh pantai maupun pulau-pulau kecil Indonesia yang terpengaruh oleh pasang surut. Kajian pola sebaran, indikator kualitas lingkungan dan ekologi komunitas mangrove Pulau Tunda dilakukan pada bulan Januari 2014 dengan tujuan untuk mengetahui pola sebaran, indikator kualitas lingkungan dan ekologi komunitas mangrovenya. Sampel mangrove diambil menggunakan transek garis dan plot yang ditarik dari titik acuan (tegakan mangrove terluar) serta tegak lurus garis pantai sampai ke daratan. Kemudian transek garis tersebut dibuat petak-petak contoh (plot) yang berukuran 10 x 10 m2 untuk kategori pohon dan di dalam ukuran 10 x 10 m2 dibuat plot berukuran 1 x 1 m2 untuk kategori semai. Pola penyebaran mangrove Pulau Tunda dianalisis berdasarkan indeks Morisita. Sementara kualitas lingkungan hutan mangrove dianalisis menggunakan tutupan pohon, tutupan semai dan jumlah jenis semai yang ditemukan. Kemudian ekologi komunitas mangrove Pulau Tunda dianalisis berdasarkan indeks keanekaragaman, dominansi dan keseragaman. Hasil penelitian menunjukan bahwa pola penyebaran mangrove Pulau Tunda tergolong beraturan (regular), dimana terjadi interaksi negatif antar individu dalam memperebutkan ruang, unsur hara maupun cahaya matahari. Selain itu, kondisi hutan mangrove Pulau Tunda masih tergolong baik dengan tingkat kualitas lingkungan vegetasi mangrove 73.74%, keanekaragaman dan dominansi mangrovenya tergolong rendah (1.20 dan 0.52) dan keseragamannya tergolong labil (0.60). Mangrove ecosystems are found throughout the coast and small islands of Indonesia which are affected by tides. Distribution pattern studies, environmental quality indicators and the ecological mangrove community of Tunda Island were carried out in January 2014 with the aim to determine distribution patterns, indicators of environmental quality and ecology of the mangroves community. Mangrove samples were taken using line transects and plots drawn from reference points (outer mangrove stands) and perpendicular to the coastline to the mainland. The line transect is made of plots of sample size 10 x 10 m2 for the category of trees and in a size of 10 x 10 m2 a plot of 1 x 1 m2 is made in the seedling category. The pattern of distribution of mangroves of Tunda Island was analyzed based on the Morisita index. While the environmental quality of mangrove forests was analyzed using tree cover, seedling cover and number of seedlings found. The ecology of the Tunda Island mangrove forest community was analyzed based on the diversity index, dominance and uniformity. The results showed that the pattern of mangrove distribution of Tunda Island was regular, where there was a negative interaction between individuals in fighting over space, nutrients and sunlight. In addition, the condition of the Tunda Island mangrove forest is still relatively good with the level of environmental quality of mangrove vegetation 73.74%, the diversity and dominance of mangroves are relatively low (1.20 and 0.52) and uniformity is classified as unstable (0.60).

Public awareness and knowledge on mangrove forest biodiversity, especially gastropods, is very limited. This study aims to compare the density and diversity index of gastropod species according to their distance from the coastline and to analyze the relationship of the two with the physical environment around them. Three lanes were placed in the southern part of the mangrove forest. The first lane (LT-1) was placed about 5 m from the coastline towards the sea. The second lane (LT-2) was placed 10 m towards the sea from LT-1 and the third lane (LT-3) was 10 m from LT-2 towards the sea. In each lane there were 10 (1 mx 1 m) plots and the distance between adjacent plots was 10 m. A total of 1.432 Gastropod individuals consisting of 16 species and 7 families were collected from 30 plots. In detail 16 species (927 individuals) were collected from LT-1, 16 species (500 indv) from LT-2, and only 3 species or 5 individuals from LT-3. The density of LT-1, LT-2, and LT-3 species respectively was 92.7; 50.0; and 0.5 indv.m-2, while the diversity index successively was 2.56 (moderate); 2.53 (moderate); and 0.95 (low). Both species density and diversity in lanes that are close to the coastline are higher than in lanes located in the direction of the sea. The base substrate on the path that was close to the coastline was clay, while on the lane that laid in the direction of the sea was sandy loam.

Bandealit is one of the resorts in Meru Betiri National Park (MBNP). This area has many endemic floras and faunas affected by the presence of invasive alien spesies plants. These plants tend to give negative impacts on savana ecosystem among them is, Lantana camara L. The distribution of this invasive alien spesies in the savana can be used to provide information about the characteristic of the environment. This study was conducted to investigate the patterns of spatial distribution of invasive alien L. camara population in the Pringtali Resort Bandealit savana region. The characters of plant species morphology was recorded for species name identification and validation. Percent cover of the individual L. camara species was collected within 50 plots (5x5 m2), while each of coordinate species found in the plots was recorded by using GPS (Global Positioning System). Abiotic factors such as temperature, pH, light intensity, and soil moisture were measured within the plots. The location of the data collection is 5,000 m2. The distribution pattern of invasive alien L. camara population was analyzed using ArcGIS and Dispersion Morisita’s Index (Ip). The result showed that 51.7% of L. camara population grew spasially close together (clumped) or overlapped one another based on the ArcGIS. This means that L. camara individuals distributein clumped pattern. While the other individuals (48.3%) grew apart randomly from each other. This distribution pattern showed by Ip value, 0.51 was also clumped or clustered. It can be concluded that the distribution pattern ofinvasive alien species L. camara is clumped because the reproduction of plant was by seeds dispersal or vegetative buds that lived around parental individuals.Keywords: ArcGIS, Lantana camara L., Invasive Foreign Plants, Morisita index, Distribution Pattern.
