Pulau Tiga was formed by continuous mud volcanic eruption. The most recent and major eruption was 20 years ago. This eruption had influenced the trend of vegetation in Pulau Tiga. The study was carried out to know the direction of succession and to identify species that lives in a mud volcanic area. The type of succession that has occurred in Pulau Tiga was also determined by carrying out this study. The dbh of the species were taken into account to determine the age of each tree roughly. The line transects and quadrate method was used in the study. The diachronic technique was used to observe the species in the study site. The dbh of species of plants that are above 10 cm only is taken into consideration. The line transects were constructed at the mud volcanic areas. The mud volcanoes are in the Casuarina Trail, Mud Volcano Trail and Larai-Iarai Trail. The most active mud volcano is in the Mud Volcano Trail. The most dominant species in the mud volcanic areas were the casuarina equisetifolia. The species could be found in every area of the island. However, the casuarina equisetifolia found in the mud volcanic areas were below 40 cm in diameter. This shows that the trees are still young and succession just happened in the area. The casuarina equisetifolia could be found in almost all the area in the island proves that the succession was random and not directed to a certain area. The species casuarina equisetifolia is the species that lives and survives in the mud volcanic area. This species serves as a pioneer species in the area. As the 1990 mud volcanic eruption was not the first to occur at Pulau Tiga, the type of succession that occurred in the secondary succession.
