|TeamSeagrass volunteers monitoring at Cyrene Reef.|
Sadly, since 2011, we noticed that the Tape seagrasses on Cyrene have been 'cropped' short. Len and Rudi did have a look at this situation in May 2012, and things haven't improved much since then.
a survey of the abundant variety of fishes found in the pool.
last year, he suggested that one reason why the Tape seagrass got 'chomped' was because it was too hot. Especially for those growing on the white sandy areas which reflects the light. Also, the rather stiff Tape seagrass tends to have a short portion standing upright, with the rest of longer leaf blade flopping over. The creased portion may have been weakened by exposure and heat.
SeagrasWatch magazine article on rays (pdf pg 23). Indeed, we have seen sharks trapped in driftnets laid on Cyrene Reef.

dugong feeding trails he saw on Cyrene, which we all missed spotting! Wow! Siti saw dugong feeding trails here in Apr 2012.
More about the trip on the TeamSeagrass blog.
Everywhere on Cyrene, the Common sea stars (Archaster typicus) seem to be a frenzy of mating, with many in arms-interlocked position and some in stacks of more than two sea stars! The rest also observed Knobbly sea stars 'standing on their toes', which is a pose they adopt to release sperm and eggs in the water. Hmm...it is coming close to the usual Mass Spawning season for corals. Hope we hear good news soon from the scientists and volunteers who are keeping a close eye on this.
floating security barriers installed at Sentosa's reef actually goes onto the reef, across the seagrass meadows there and onto the natural cliffs! Oh dear. I'm worried that this will have some impact. Some of us will soon be taking a closer look at this shore to see what is happening there.
'flood' of brown sediment-laden water that can affect marine animals and plants. Monitoring of seagrasses helps keep track of how these coastal ecosystems are coping with these and other threats.
what marina life can naturally settle on artificial structures if we keep the water clean and protect the natural sources of 'babies'.
Tomorrow we take Len and Rudi to Chek Jawa to see how the seagrasses are doing there.
