2007 - 2008 Biodiversity Impact Assessment (BIA) for Mangrove Boardwalk and Pedestrian Access improvements at Berlayer Creek, Singapore

The 5.61 ha Berlayer Creek is part of the Labrador Nature and Coastal Walk and currently contains one of two remaining mangroves in the south of mainland Singapore. The creek is also home to a diverse group of flora and fauna with mainly three types of habitats – mangroves, rocky shores and mudflats.

Enviro Pro was assigned by Urban Redevelopment Authority (URA) to conduct a BIA for the development of a 960 m nature mangrove boardwalk at Berlayer Creek. This BIA helps to determine the optimal arrangement and design of the boardwalk such that the impact to the existing ecosystem is minimal. The advantages and disadvantages for all possible designs of the boardwalk was discussed in the BIA.

A number of mitigation measures were also suggested by Enviro Pro to ensure that species of flora and fauna of conservation concern can still be found at Berlayer Creek after the development of the nature mangrove boardwalk.

Key Study Methods

Biodiversity Assessment – Species of flora and fauna were identified by surveyors. Mangrove vegetation and avifauna surveys involved walks and boat surveys. Specific walks through the mangroves and inter-tidal flats were made during low tide to survey for mollusk and crustacean groups.
