ABSTRACT: This study aimsed to
examine the association of Tengkawang (Shorea spp) with other species that
dominate in Tembawang forest and examine the pattern of distribution / spread
ofTengkawang in Tembawang forest of Nanga Yen Village, Hulu Gurung District,

transects lines withlengths of 20 x 500 m respectively. The research found 65

Dipterocarpus sp, and Dilleniaindica; and between Shorea marcophylla withDipterocarpus
sp; with high association criteria on value 0.74. ~ 0.49. The distribution
pattern of Tengkawang (Shorea spp) were uniformly spread on class of pole,
sapling and seedling withI value was I <1. Meanwhile for the class of tree,
