Description:With the increasing demand of marine resources throughout the world, it is important to establish a foundation to determine how the use of resources is affecting the health of marine habitats. An initial assessment of Koror's Ngemelis Island Complex was conducted to establish a baseline database to support long-term adaptive management of the protected areas in Palau. A total of 39 sites within Ngemelis Island Complex were randomly selected and surveyed over five days between October 26 and November 3, 2015. The survey was specifically geared to assessing the benthic community, coral recruits, commercially important invertebrates, and the abundance and biomass of commercially important fish. The sample design was habitat-stratified with the number of sites being proportional to the size of each habitat. These habitats include the back reef, channel, fore reef, lagoon, reef crest, vertical wall, and an unknown habitat. This assessment shows that fish abundance and biomass are the most dominant on the vertical wall where turf and crustose coralline algae were the predominant benthic substrates. Coral recruit density was observed to be the most dominant on the fore reef where carbonate was the most dominant benthic substrate and invertebrate density was observed to be the most dominant in the channel where Acropora sp. and sand were the predominant substrate
