| Abstract: |
Investigation
was carried out in the Kachchh mangroves of Gujarat
to delineate its structure in a coastal stretch of 300 km. A clear trend of
salinity increase from Mundra to Kori creek could be observed. Mean creek water
salinity ranged from to 38.8 to 41.5 ppt. Station-wise mean density of mature
trees ranged from a minimum of 832/ha to a maximum of 1900/ha with tree heights
reaching up to 10 m. Mean density of mature trees decreased in the order of
Kori-Jakhau-Mundra-Medi-Laki. Height and GBH classes in the range of 1.6 to 3 m
and 21 to 40 cm, respectively predominated in all stations. Among 5 major
stations both maximum (491666/ha) and minimum (4545/ha) regeneration density
were recorded at Jakhau. Density of recruitment class was fairly high at all
the stations ranging from 2240/ha at Kori creek to 7783/ha at Medi. Mangroves
of Kori creek had high regeneration potential as evidenced by high entry of
recruitment class to mature tree category.
