Authors conducted a study to determine the ecological value (ecoval, symbolized as I Epsilon) of the structure and dynamics of forest biomass at the tropical evergreen Alaia-Streblus forest of Meru Beteri National Park (MBNP), East Java, Indonesia. This study focused on investigating the structure of plan communities, ecoval of forest biomass, and carbon stocks, and appraising the ecoval of forest biomass. There were 43 families, 67 genera, and 78 species of plants found in the MBNP. The diversity index of plant species in height : greater or equal to 1 m was moderate (2.7), while others were low. Aglaia argentea and Streblus spinosus were dominant plant species of level greater or equal to 1 m height; seedlings of Tractera scandens, Donax canniformis and Panuicum repens of were dominant species of the understory, while Schizostachyum zollinge-Caryota mitis were the dominant species of tree-like plant communities. The plant species (greater or equal to 1 m height) of the MBNP contributed the highest forest biomass ecoval (+- 3, 500 Mg/ha), which resulted in high ecoval of carbon content (1.74 Mg/ha). Using the cost approach, the ecoval of Agiaia-Streblus forest biomass accounted for about USD 601,361 to USD 1,081,495 (IDR 7,705,244,167 to IDR 13,857,197, 433) per hectare. These high I Epsilon reflect the potential value of forest structure and biomass in the MBNP, especially as a carbon sink in Java Island, in particular, and Indonesia in general. The I Epsilon can inform the valuation of natural resources so that the government or management in charge can use this information to conserve the existence of forest structures and functions; and to generate plans, actions and policies to sustain this forest ecosystem.
