Seagrass is a kind of most productive ecosystm in shallow sea water and has strategic role as producers. This aim of this study is to know the community structure, density, and population distribution patterns of seagrass in Plengkung Beach District Banyuwangi. The data was collected on September 2013 using plot transect method. The size of plot that's used is 1×1 m² .The result of research have shown the kind of seagrass that found in plengkung beach, is Thalassia hemprichii, Halodule pinifolia and Cymodocea rotundata.

Cymodocea rotundata is a higest density species (16,578 individu/m²) in 2^nd station. The environment factors have correlation with seagrass density, so it has contributed to decide the community structure and seagrass pupulation density.
