Composition and Status of Undergrowth of a Deforested Area in Bangladesh

M. Al-Amin, M. Alamgir and M.R.A. Patwary    

Abstract: The study described the composition and status of undergrowth (shrubs, herbs and grasses) in a degraded deforested area of Chittagong (South) forest division, Chittagong, Bangladesh. A stratified random quadrat method was used in the study. The area on the whole consists of 45 species of undergrowth of 31 families. Shrubs layer includes 14 species of 12 families and herbs and grasses include 31 species of 19 families. Among the shrubs Clerodendrum viscosum shows the highest density (94 plants/100 m2) and Cassia alata shows the lowest density (8 plants/100 m2). The highest frequency was found in Clerodendrum viscusum (50%) and lowest frequency was found in Corcorus capsularis (5%). The highest abundance was recorded in Corcorus capsularis (13) followed by Ipomoea fistulosa (11) and Lantana camara (11). Among the herbs and grasses Imperata cylindrica shows the highest density, frequency and abundance (7638 plants/100 m2, 77% and 394, respectively) followed by Cynodon dactylon (687 plants/100 m2), Unidentified–4 (265 plants/100 m2). The lowest frequency (5%) and abundance (3) were recorded in Pueraria sp. and Musa paradisiaca, respectively. Abundance frequency ratio of each shrubs, herbs and grasses are >0.05 showing the contagious nature of each species distribution.
