Abstract

The research was conducted to study the structure and composition of herbaceous and seedling communities (understorey species)occurred on herbivore habitat within Cikepuh wildlife sanctuary. A series of 25 plots of 1 m x 1 m each with an interval of 5 m were used to establish a species-area relationship. The proportion (percentage) of canopy (leaf) coverage of each species occurred within the sampling plots to the sampled soil surface area was measured. A total of 54 species belonging to 47 genera and 29 families occurred in the 25 plots develoved, with the species diversity index (value) of 2.09 using the Shannon Wiener formula. Nine species were categorized as herbaceous plants (16.67 %) while the other 45 species were categorized as seedlings (83.33 %). The average density measured was 39 individuals/m or c. 386.400 individuals/ha. The most dominant family is Euphorbiaceae (possessing 5 diffrent species) while the most dominant species is Urochloa subquadripara (Poaceae) with and importance value of 96.08%.

Abstract

Penelitian ini bertujuan untuk mengetahui struktur, sebaran, dan tata ruang jenis-jenis anggrek epifit yang ada di hutan pantai Cagar Alam Sempu, Malang, Jawa Timur. Penelitian menggunakan plot memanjang 10 m x 1.000 m (1 ha), yang dibagi menjadi 100 anak plot. Letak plot dari Pantai Semut ke arah Pantai Sumber Air Tawar. Seluruh jenis anggrek epifit dalam plot dicatat dan dihitung jumlahnya (rumpun). Hasil menunjukkan terdapat empat jenis dari tiga marga, dengan kerapatan 77 rumpun/ha. Jenis dominan adalah Taeniophyllum cf. biocellatum, diikuti Dendrobium subulatum, Grosourdya appendiculata, dan Dendrobium crumenatum. Pola tata ruang sebaran berdasarkan tiga parameter indeks dan uji chi-square bagi setiap jenis menunjukkan adanya pola acak.Structure, Distribution, and Spatial Patterns of Epiphytic Orchids (Orchidaceae) at Coastal Forest of the Sempu Island Nature Reserve, Malang, East Java AbstractThe aim of this study is to know the structure, spatial pattern, and distribution of epiphytic orchids in coastal forest Sempu Nature Reserve, Malang, East Java. This study used an elongated plot of 10 m x 1.000 m (1 ha), and was divided into 100 subplots. The location of plot was from Semut Beach to the direction of Sumber Air Tawar Beach. All the epiphytic orchids species of inside plot were recorded and counted (clumps). The results showed that there was four species from three genera with density of 77 clumps/ha. The most dominant species was Taeniophyllum cf. biocellatum, followed by Dendrobium subulatum, Grosourdya appendiculata, and Dendrobium crumenatum. Spatial pattern of distribution based on three parameter indices, and chi-square test showed that every species showed a random pattern.
