Abstract/ Executive Summary:

The present article focuses on the status of angiosperm plant diversity of Nijhum Dweep, a small Island in the Bay of Bengal close to Hatiya channel. From the analysis of the data a total of 152 plant species belonging to 56 families were recorded. Among the recorded species, tree represented by 66, shrub by 15, herbs by 58 and 13 by climbers. Of the species recorded from the area, 51 % species represented by 11 families and 49% represented by 45 families. Fabaceae appeared to be largest in the Dicotyledones having 10 species whereas Poaceae was the largest in Monocotyledones having 12 species. Analysis confirmed that 68% of the recorded species found to be of medicinal and 32% used tor other than medicinal purposes. Data analysis also showed that homesteads supported maximum plants followed by road side, cultivated land, mangrove and mangrove meadows. Collected data revealed that the occurrence of seven species namely Bruguiera gymnorrhiza, Diospyros blancoi, Derris trifoliata, Heliotropium curassavicum, Tamarix gallica, Typha elephentanea and Sarcolobus carinatus in the study area might be rare. Dolichandrone spathacea, a threatened of plant species of Bangladesh, was also found in this mangrove forest area. Through observations and discussion with local people, a number of threats to plant diversity were identified as well. Finally, a number of possible conservation measures have been suggested for the management of angiosperm plant diversity of Nijhum Dweep.

Keywords: Assessment, Angiosperm, Plant diversity, Nijhum Dweep

Location: Nijhum Dweep

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Conservation and Biodiversity

Commodity: Plant

Objectives:

To assess the angiosperm plant diversity of Nijhum Dweep
To identify any threats and to suggest some possible conservation measures for the diversity conservation.

Methodology:

Plant sample collections were done at a suitable time of the year of 2013 and 2014 paying three visits. Specimens were collected from mangrove, meadow, cultivated land, roadside and homestead area. Special efforts were given to find species of conservation concern including threatened, endemic and rare. Voucher specimens processed using standard herbarium techniques. The specimens were identified consulting different Floras viz., Hooker 1872-1897, Prain 1903, Uddin and Hassan 2004, Siddiqui et at. 2007c and Ahmed et at.200.8a, 2008b, 2009b, 2009c, 2009d, 200ge. Specimens available at Dhaka University Salar Khan Herbarium (DUSH) were consulted in identifying the collected plant specimens. The updated nomenclature of the species followed Siddiqui et al. 2007c and Ahmed et at. 2008a, 2008b, 2009b, 2009c, 2009d, and 200ge). Voucher specimens are deposited at DUSH.

Achievement/Findings:

The study suggests for further long term research to focus on all aspects of angiosperm plant diversity to help in making proper management plan for this Island. If managed properly, the Nijhum Dweep could be fascinating to tourist and also might be a good sources of earning revenue for the country. Local communities would also be benefited from such measure.
