9 SF in Senami. The density value of A. scholaris varied among the
ecosystems. The highest value was 0.0940 which could be found in SF followed by CPF in Senami and JR in BDNP. The total volume with the
highest of 12.32 m3ha and frequency of 22 trees per hectare could be found SF in Senami. The mean diameter of A. scholaris varied from 17.86 cm to
31.18 cm that could be found in JR and SF in Senami respectively while the tallest A. scholaris could be found in SF of Senami with the height of 10.50
m followed by JR in BDNP with the height of 10.40 m See Table 2. Table 2. Distribution pattern and dimension of A. scholaris growing in

The Table 2 showed that the A. scholaris was more dominant and had better dimension in Senami landscape compared to BDNP landscape. As
described before, A. scholaris plays an important role in the forest succession processes. It is a pioneer species which is easy to propagate and
able to grow in many types of soil therefore, it will occupy the most degraded forests for the first phase of succession [2].
