Abstract/ Executive Summary:

Gewa is an important industrial tree species of the country. It is used extensively for producing pulp, match sticks and match boxes.Gewa is an important mangrove tree species occupying about 16% of the Sundarban forest of Bangladesh.It also been reported that there are enough regeneration (2700/ha) for sustainable production of gewa wood to feed the KNM and other match industries in the country. It is a dominant species in the moderate saline zone of the Sundarban. It occurs as a mixed species with Sundri in the fresh water zone and with goran in the strong saline zone.Gewa is the principal raw material used by the Khulna News print Mills(KNM) and various match industries in khulna.

Program Area: Postharvest and Agro-processing

Commodity: Gewa

Objectives:

To know the harvesting, transportation and regeneration status of Gewa in the Sundarban of Bangladesh

Methodology:

Gewa is harvested in the camp sites having an area of 3-4 ha. The sites are placed centrally within the annual coupe under the gewa working circle. The camp sites are shifted almost every year, clear felled and planted with gewa seedlings collected from the forest floor.Felling operation is done under selection cum improvement system on 20 year felling cycle. Annual allowable cut is calculated on the basis of the estimated merchantable volume of Chaffey et at. (1985). KNM is interested to increase the production of gewa wood in the Sundarban and the annual extraction target is 0.13 million cu.m.(4.7mcft). A total of 0.67million cum. Gewa wood will be extracted from an area of 1,10,146 ha during the five year plan period from 1995-96 to 1999-2000 maintaining a 20 years cutting cycle.
