Panjang island is a small island in Indonesia which is administered in the territory of the district Jepara, Central Java, Indonesia. Small island properties are susceptible to changes and environmental pressures so it is important to be maintained and protected. Community tree is a component of the ecosystem that plays an important role in protecting the environment. The purpose of this study is to assess the composition and diversity of tree species as a basis for conservation of small islands. The research method is purposive sampling. Research site is was choosed four points located in the southern, eastern, northern and western Panjang island. Each point of the transect line drawn perpendicular to the coastline and put the research site from the beach toward the land. Vegetation data were analyzed by calculating the Importance Value Index, Degree of Constancy, Diversity Index and Evenness Index. There are 33 species of trees belonging to 19 families. Diversity of tree species (H') : 1,58-2,22. In Panjang island there were 2 important tree: Phemphis acidula (Setigi) which has the status of Least Concern IUCN and Excoecaria agallocha (wood blind) that are endemic in Java, so that these two species need to be protected population. Tree species that plays an important role in conservation on Panjang island are: Leucaena leucocephala, Bombax ceiba, Thespesia populnea, and Acacia mangium. Keyword: Small island, protected population, species diversity index, endemic species, purposive sampling
