Abstract
This study was conducted to determine the condition of seagrass existing in the coastal waters of the District of Kei Besar Utara Timur. The purpose of the study is to examine some of the important aspects of the condition of seagrass. The research found four species of seagrass, namely Cymodocea rotundata, Enhalus acoroides, Halodule pinifolia, H. uninervis, and Thalassia hempricii. Seagrass was found in coastal waters in station I, station II and station IV with the highest number of seagrass species of four (4) species, whereas at the coastal waters of station III only one (1) species was found. Cymodocea rotundata species spread throughout the research stations. Halodule pirifolia was a species that came with the highest density (1019 teg./m2). The highest percent cover was represented by Enhalus acoroides, Halodule pinifolia dan Cymodocea rotundata species (90%). Based on the approach of percent cover as stipulated in the Decree of the Ministry of Environment No. 200 of 2004, the condition of seagrass in the coastal waters of the District of Kei Besar Utara Timur was categorized into good condition (rich / healthy).
Highlights
Seagrass is a coastal ecosystem that is covered by seagrass as the dominant vegetation
Community of seagrasses in coastal waters of the District of Kei Besar Utara Timur had an uneven distribution; From the waters of Hollat village to the ones of Ohoiraut village, there were four (4) species of seagrass found in those coastal waters including: Cymodocea rotundata, Enhalus acoroides, Halodule pinifolia, H. uninervis, and Thalassia hempricii
The species spread evenly in each coastal waters of District of Kei Besar Utara Timur because in every sampling location a number of species was found per sampling site
Summary
Seagrass is a coastal ecosystem that is covered by seagrass as the dominant vegetation. Seagrass is a group of closed seed plants (Angiospermae) and Monocots capable of living permanently below sea level [1]. The presence of seagrass communities in a body of water contributes to the value of marine productivity. Seagrass beds found in nature are often associated with other aquatic fauna and flora, such as algae, meiofauna, mollusks, echinoderms, crustaceans and various types of fish. These associations form a complex ecosystem in seagrass beds [2]. The loss of seagrass communities in the waters, will affect the food chain existing in this community
