Terrestrial recce, Pulau Semakau, Singapore, 4th August 2007

Much has been known for Semakau's intertidal fauna and flora through the joint efforts by various parties, which concern about the biodiversity of the landfill island in the recent years, species of the terrestrial component are rarely reported. Species list of forest plants and birds have been listed, while that of invertebrates and other mammals almost remains unknown. As an attempt to fill this gap, Hung Kei, Hung Bun and myself form a volunteer survey team to recce the site, and to conduct a "quick and dirty" first hand data collection.

To access coral reef beach of the island, everyone has to pass a forest trail. For those have been there, the density and the strength of mosquito bite are surely the unforgetable experiences. In many a time, people will just covered themselves with whatever means, or/and running through it so as to get less bites. But for us, we are aiming to survey this place, back and forth slowly looking for various kinds of insect and spiders. Those mosquitoes were happily enjoying their unexpected food source.

The recce trip is rewarded quite well with a list of of spider species, and some of insects which have been spotted....
