In all there has been collected 68 species belong to 31 families with the total individuals varies between 9 - 95 ind./0.3 m2. The species richness (S), Shannon Wiener diversity index (H’) and Pielou’s eveness index (J) consecutively range between 3-24, 1,03-2,93 and 0,83-0,94. Spearman corellation test indicates positive relationship between worm density with species reachness and shannon wiener index.
