A comprehensive tree survey has commenced in Sundarbans mangrove forest to assess the diversity and abundance of tree species. Under the supervision of the forest department, the survey began on Tuesday and is slated for completion within the next three months.
The primary objective of this survey is to ascertain the number and variety of plants across the 4,142.6 square kilometers of land within the Bangladesh portion of the Sundarbans, spanning a total area of 6,017 square kilometers.
Historical data from the Forest Department indicates a fluctuating trend in the number of plant species within the Sundarbans. In 1903, the forest harbored 334 plant species, including 165 algae species and 13 orchid species. However, subsequent surveys revealed a decline, with only 66 forest and shrub species recorded in 1985, and a further reduction to 48 species in 1997.
In the most recent survey conducted during 2014-15, the number of tree species rebounded to 184, showcasing a diverse array of flora within the Sundarbans. This includes 54 tree species, 28 foliage species, 13 shrub species, 22 herb species, 13 fern species, 12 orchid species, 3 parasitic plant species, 2 palm species, 28 grass species, and 9 fungal species.
Presently, the Sundarbans is dominated by Sundari, Gewa, and Garan trees, constituting 70 percent of the total vegetation. However, conservation concerns arise as five species, including Lahur, Banabakul, Mahajani Lata, and two orchid species, are listed as endangered.
Kazi Muhammad Nurul Karim, Divisional Forest Officer of Sundarban East Forest Division, emphasized the importance of the ongoing survey. He stated that the objective is to comprehensively document the tree species across the entire Sundarbans region of Bangladesh. Forest officials and department employees are diligently conducting the survey, with plans to conclude within the stipulated three-month timeframe. The results of this survey will provide valuable insights into the botanical richness of the Sundarbans and aid in formulating conservation strategies for its diverse flora.
