摘      要：The semi-arid mangroves of the Gulf of Kachchh,the largest ecosystems on the west coast of India,are poorly studied in terms of vegetation structure and environmental parameters in spite of their conservation ***,it is necessary to document the structural features of these mangroves in view of ongoing coastal industrial *** forest structure in 10 locations on the northern and southern coasts of the Gulf of Kachchh were assessed using the line intercept transect *** included density of young and mature age classes,tree heights,diameters at breast height(DBH)and aboveground biomass,along with seven significant environmental *** tree densities ranged from 350 to 1567 ***-1,while average height and girth at breast height ranged from 1.0 to 6.8 m and 3.0 to 137.0 cm,*** majority of trees(55.6%)were in B 1.8 m height class followed by a 1.9 to 2.4 m class(25.1%).DBH was most often in class 2 cm or lower than *** the canopy index classes,more trees were recorded in class ≤2 *** regeneration density was greater than the recruitment *** study indicates that the poor structural attributes of Avicennia marina *** Stapf and Mold dominated mangroves are largely due to aridity induced by scarce and erratic rainfall and high soil and water *** results should be valuable in conserving and sustainably managing these mangroves in the face of developmental activities.
