摘要:In Indonesia which has thousands of islands, the inventory and evaluation of natural resourcesof islands, including in the outermost islands, should be done to provide accurate and up-to-date baselinedata that can be accessed quickly to support the sustainable management of natural resources. Theobjective of this paper is to present part of the inventory results of natural resources on Rote and nDanaislands in East Nusa Tenggara Province, Indonesia, especially regarding change in land use and landcover from 2000 to 2014 and the composition of the mangrove ecosystem at several points ofmeasurement. Land use and land cover were interpreted from Landsat satellite imagery acquired in 2000and 2014. Primary data of the mangrove were obtained through measurements during field surveys atfour stations. The results of the research indicated that land use and land cover change in this outermostand remote island were generally static. Changes in land use and land cover appeared to be only slightlyaffected by the population which is still few in the area. Nevertheless, mangrove destruction has begun.Distribution in all mangrove strata (seedlings, saplings and trees) on Rote and nDana islands was notspread evenly and was different at each station observed. At stations where the substrate was sandymuds, Rhizophora mucronata was the dominant species. In the stations where the substrate wasdominantly muddy, Avicennia alba and Ceriops tagal were dominant. On the nDana islands, themangrove was found on a plateau of the island, with Avicennia spp. and Heritiera spp. which were thedominant species. This research describes the diversity of the mangrove in different locations at differentstrata. This description should become part of the database on the mangrove ecosystem in remote area.
