Moulavibazar and Bibiyana , Jalalabad Gas Field
Partner Organization : SMEC International
Start Date : April 2009Completion Date:March 2012

Name of Joint Venture Consultants:

IUCN, Bangladesh and Centre for Sustainable Development (CFSD)

Description of Project:

The overall objective of the project was to assess local biodiversity and identify the threatened species nationally and internationally in the project area. This recommendation will go to the EIA report. We have prepared the list of biodiversity in the area and identified the threatened species according to the international guidelines.

NACOM Deliverables :

Organized staff and field team and trained them for data collection.
Data collection on local flora and fauna maintaining al standers.
Meeting with local stakeholders
Data analyses through computer software.
Identify the threatened species of the area and categorize in the IUCN red list.
Prepared report and made recommendations for protection during intervention.

Key Achievements:

Aquatic Sampling:
The aquatic habitat survey was restricted to river habitat only. The survey of river habitat will included the parts of the Kushiyara river that consist of the retaining wall as well as the zone (mainly downstream) that is likely to be influenced by the river training activities and as well as due to changes in flow regime, if any
Within the riverine habitat observations were made on the fish diversity, mollusks, prawns and other aquatic animals, including the dolphins. Special efforts were taken to collect information on the foraging, resting and breeding areas within the survey area
The identified river habitat was also checked for the existence of any important fishing ground, fish sanctuary, breeding/spawningv and nursing ground of fish and other aquatic mammals.
Fish and prawn survey was carried out by making observation on fisher’s catch, local fish market survey and interview of local fishers.
Benthic sediment samples were collected from the river bed/bank where the retaining wall was constructed to document the occurrence of the benthic organisms that might be affected due to river training.

Terrestrial Sampling:

As per requirement of the DoE, 5 km terrestrial habitat area was investigated.Survey was carried out comparatively intensively within the immediate vicinity of the river bank. Special attention will be given to riparian vegetation.
The faunal and floral survey within terrestrial habitat included plants (Pteridophyte to Angiosperms), birds, mammals, reptiles and amphibians. In addition to the occurrences of species, information was also collected on the seasonality in appearance, macro-habitat preference, relative abundance, etc. In addition to direct observation, extensive interviews of local people was taken to collect these information
Observations were also be made on the occurrences of animal colony, roosting areas of animals. Local accounts regarding the occurrence of animal and plant species, trend in changes in local biodiversity, migration, migratory corridor, breeding and breeding ground of animals, etc. was captured.
  Efforts were taken to document the habitat features, detailing the faunal and floral composition and extent of such habitats within the Survey Site. All observations geo-referred and therefore help in the development of GIS based maps showing the habitat features and their extent.

Identification of Critical Species and Areas with the Project Site:

The individual floral and faunal species were assessed to identify the critical species that requires protection and are protected by laws and legislation.
Assessment was done for the identification of critical areas within the project site. The identification process will based on a number of criteria, presence biodiversity hotspots, presence a number threatened and protected flora and fauna, pristine and remnant habitats, migratory route and roosting areas for animals, important breading ground, etc.

Assessment of Biodiversity Conservation sSgnificance and Constraints to the project site

Based on outcomes of the activities outlined in above, an overall assessment of the survey area was determined its conservation significance. Whether the area or part of it is essential for the survival of the critical species in the country or within the Sylhet region. In practical, we will assess conservation significance at the level of species as well as at the level of ecosystem. Extensive expert knowledge will be utilized in this process.

Identification of Potential Environmental Impacts (Biodiversity)

The construction of retaining wall will involved increased transpiration and traffic, dumping of concrete blocks, fixing of geo-textiles, leveling of river banks and others. We have checked with each of the field activities of the survey and examine whether such activities are likely to cause: lethal or sublthal effects to biota, disturbances to animals (frightening, avoidance, etc.), destruction of important vegetation, reduction/disturbances to natural breeding and recruitment, affect migration and migratory pattern, disturb resting and roosting of animals, reduce natural regeneration process, reduce the aesthectic values of habitat/ecosystem and reduce the ecosystem services.
