Sylhet falls under Zone I with high seismic coefficient and near seismic sources. As such, Sylhet is in an earthquake prone area.

7.3.2. Biological Environment
7.3.2.1. General
165. A preliminary assessment (review) of floral and faunal diversity was carried out around the project site through site visit and consulting with the officials of the different departments working in Companiganj upazila. The main purpose of this survey was (i) to explore the plant and wildlife species (ii) to investigate the distribution and abundance of flora and fauna including fish species, and (iii) to make the preliminary assessment of the impacts of the proposed project activities on the ecological environment.


7.3.2.1.1. Flora and Fauna
166. Companiganj Upazila contains the best reed swamp remaining in the region and also has some floodplain grassland. The area has also been identified as a mother fishery, especially during the rainy season.

167. Two types of ecosystem exist in the project site and adjacent area viz. terrestrial and aquatic ecosystem. The project site comparatively has low floral and faunal density. The project site has some natural vegetation (Herbs and Shrubs). The site is predominantly covered by weeds and grasses, with traces of shrubs but no tree. Binna son, Ara, Ekor, Murta, Ghagara and Bish katali are the common native species in the area. The soil is generally covered with green grass and weeds.


168. The KataKhal River situated adjacent to the project site is the habitat of a number of small fish. The site is devoid of any significant animal presence. Some of the local people, however, graze their livestock, mainly goats and cattle in the site area. Insects and a few small birds were found at the project site. During the site visit on 23 December 2014, observed some ‘Snail Mound’ inside the area. The terrestrial and aquatic flora and fauna at the project site are shown in photographs (06 - 11).
169. A borrow pit which is almost 60 feet width is situated along the highway and passes on the west side of the land. The borrow pit can retain water even after the rainy season and continues till October to November. When there is water some small fishes grow in the borrow-pit and local people usually clean their cattle with this water. This Borrow-Pit can be used as a water body during project life, making retaining wall both sides to avoid possibility of any erosion and borrow pit also can be used for any recreational purposes to make the view of the project scenic and attractive for the visitors. Over this barrow pit a bailey bridge can be built to enter the project from the highway.
