- Abstract
Erek-erek is Ijen Geopark Biosite located in an area above 1000m altitude. It is a primary tropical rain forest ecosystem in a quarter volcano which is already in the stage of climax succession because the canopy stratification is very complex. However, there is limited information on the tree vegetation that composes this Ijen Geopark Biosite, therefore a study aimed to estimate the species diversity and ecological value was carried out. Tree data collections were sampled in 10x10m2 plots. All tree species in the plots were identified and its parameters such as trunk diameter, height, canopy height, canopy width, and canopy density were measured. The tree species composition and dominance were analysed based on the taxa. Furthermore, species diversity was calculated by Shannon-Wiener formula while ecological values were analysed by calculating ecoval formula. The tree vegetation of Erek-erek Biosite consist of low number species composition (14 families, 16 genera, and 17 species). This community had moderate species diversity and was dominated by Dendrocnide sinuata (Blume)-Trema orientalis (L.) Blume. The total ecoval of tree vegetation of Erek-erek biosite is 5,299,281.89 million IDR/ha of which 99.98% was contributed by the structure value (Rp. 5,298,725.56 million/ha). The function value of carbon stock only contributes 0.02% or 556.33 million IDR/ha. The large number of individual populations of the species D. sinuata (Blume), Syzygium aqueum (Burm. f.) Alston, and T. orientalis (L.) Blume play an important role in big volume dimensions of structure value. The Ficus genera that have big diameter with high trunk contributes to high structure values, namely 11,343.36 million IDR/tree in average.
