    This study aimed to determine the regeneration status of Sialang tree. This study had been conducted from November 2012 to December 2012 in Kepung Sialang forest, Dundangan Village, Pangkalan Kuras, Pelalawan District, Riau Province. The method used in this study was purposive sampling method, by placing nested plot around Sialang stree. A total of 25 plots were examined. The size of plot for tree, pole, sapling and seedling were 20 x 20 m, 10 x 10 m, 5 x 5 m and 2 x 2 m respectively. The result showed that there are six Sialang trees, i.e Rumah Keluang tree (Dipterocarpus confertus Sloot.), Kempas (Koompassia malaccensis), Sulur Batang (Shorea sp), Kayu Batu (Irvingia malayena), Kedondong (Spondias pinnata) and Ara (Ficus benjamina). The vegetation structure of Sialang tree at seedling stage was dominated by Sulur Batang, while for sapling and tree were dominated by Rumah Keluang. The highest Important Value Indexs for tree, pole, sapling and seedling were 154.8556 (Rumah keluang), 300 (Rumah Keluang), 146.2927 (Rumah keluang), 123,20707 (Sulur Batang), respectively. Keluang tree (Dipterocarpus confertus Sloot.) had the best regeneration status. Morista distribution index for all of the Sialang trees showed a clustered distribution.
