Scops Owl at the TRACC Tip of Borneo camp

This unfledged baby Scops Owl fell out of a coconut tree a couple of weeks ago. He spends his days snoozing safely in a cat box and his nights hopping about the place, nibbling people's ears and learning to fly. ‪#‎TRACC‬ ‪#‎conservation‬ ‪#‎volunteer‬

Marine Science A Level Fisheries Fieldwork

Parrot fish from coral reef fisheries

The Marine Science A level class had a lot of fun and learnt a lot by being in the environment during fieldtrips.  The students and staff from TRACC had lots of fun doing many practicals in mangroves, rocky shores and underwater on coral reefs. These are some of the images from the Fisheries fieldwork done by the 2015 Marine Science A level class.

UPDATE

One of our students was the Best #Marine #Science #student in the world. What an honour. Congratulations #TomGibson http://goo.gl/mTx4ge

Coral planting on step reefs to repair sloping rubble reefs

The step reefs with coral biscuits to repair sloping coral reefs
were built by the Kalapuan community
as part of the TRACC SGP/GEF project

The Tracc SGP/GEF coral planting project has been busy building step reefs to hold the biscuits and repair sloping rubble reefs.  Pom Pom Island and many of the reefs in the Semporna district have a very steep slope of rubble.  The reef crest was blasted by bomb fishers in the past and now all that is left is a slope of coral fragments.  These are unstable and move gradually down the slope.  Most larval corals which settle are abraded off or smothered by the sand as the rubble rolls down the slope.


The community of Kalapuan island has been building our complex step reefs during 2014.  Made of cement mortar with two rows of bottles, the back row of bottles is taller than the front.  The undersurface during manufacture or the top surface after positioning has indentations which correpond exactly with the shape and size of our coral biscuits in the nursery.

The step reefs with coral biscuits have a variety of coral species
to increase diversity of the repaired coral reefs.

To date (May 2015), the community has built slightly over 250 of the steps which will be sufficint to make many cluster or auditorium reefs and will provide long term protection for nearly 2000 coral biscuits from our coral nursery.

Creating igloo reefs - on land

Igloo reefs to attract shoals of fish

The team of Malaysians and international volunteers have been having fun over the past few weeks making igloo reefs for our SGP/GEF project near the Tip of Borneo (Simpang Mengayu). These are bottle reefs attached together by plastic pipe bent into an arch shape and then assembled into an igloo shape. The plastic pipe has a large number of holes drilled in it to make a suitable attachment point for coral fragments which will be fixed by cable ties. These igloo reefs are intended to act as very open shelters to schools of fish.

The igloos were assembled and labeled on land and then the various parts were taken apart to make for easy transport in the boat and underwater.

Making bottle reefs for coral planting

Preparation of the moulds

Artificial Reef preparation and construction is an ongoing process at TRACC, some part of the process happens for 6 from the 7 days of the week.

This week, our Malaysian staff and volunteers were building more bottle reefs in the moulds. The moulds are lined with plastic to stop the cement sticking to the wooden sides or becoming dry by losing all the moisture down into the sand floor. Each mould is about 10ft long, made of a wooden frame. The cement is mixed by the very nice new mixer bought with the support of the Small Grants Programme of the Global Environment Facility (SGP/GEF). The mixture of sand and cement is a wet mortar and we use a plasticizer to give the mixture more workability. The sloppy mortar mixture is poured into the moulds and then the bottles can be added.

Bottle reefs waiting for the cement to set overnight.

Each bottle is pre-cleaned to remove the labels and any residue of contents. We only use bottles which have contained food or drink so that there is no risk of pollution from the bottle contents.

The bottles are rolled in the wet cement mortar so that they have a slightly roughened surface from the cement and sand. When this layer is hard it helps the attraction and settlement of a wide variety of sedentary reef building organisms such as sponges, ascidians byozoans as well as hard and soft corals.

The bottles are worked into the bed of mortar so that they stand upright and are submerged by 3-5 cm in the wet mortar. Generally the bottles are positioned about 7-12 cm apart. If they are too close then it is hard to make the block so that it doesn't fall apart when it is set. If the bottles are too far apart, then the coral fragments or biscuits could move out of the protective ring of bottles and fall into the sand. All sizes and shapes of bottles can be used; from jamjars to ketchup to beer bottles.

Plastic water bottles are not normally used because they can come out of the cement base when there is wave action. Fizzy drink bottles can be used but we puncture holes near the base so that the cement mortar goes into the bottles and helps to lock them into the bottle reef block. Most of the bottle reefs for coral planting use only glass bottles which are not in short supply. Glass is not recycled in Sabah because of the cost of shipping to Peninsular Malaysia. Consequently there are plenty of bottles which are donated by caring citizens or businesses.

The raw material for our artificial reefs is cheap and plentyful and with photos and videos of the results from our SGP/GEF project near the Tip of Borneo (Simpang Mengayu) and on Pom Pom island near Semporna, will lead to more community action projects around the region using the techniques we are developing to improve and rebuild the reefs close to each village.

Growth of the branching corals in the coral nursery

Shark cave reefs

This week, our Malaysian community workers and our international volunteers have been making shark hiding reefs. This is the TRACC version of proactive marine conservation. Our philosophy is that if we see a problem, then we should work towards a solution.

From the plastic recycler, we aquired a number of large flat trays which were ideal for the roofs for caves for sharks. We attached crate reefs filled with plastic waste (cutup water bottles) which increases the surface area for sponge and cryptic organism settlement as well as providing a myriad of small spaces for post larval and juvenile fish crabs and other tasty small organisms to hide. The design gives a sheltered cave environment similar to the caves we have seen being used by bamboo and coral cat sharks. The upper surface of the cave and the crate supports will be planted with corals which will eventually completely camoflage the artificial reef structure.

During our surveys, it was noted that there was a lot of food for benthic sharks such as coral cat sharks, brown banded bamboo sharks epaulete sharks and nurse or leopard sharks. Unfortunately the sharks are rare if not completely absent from the reefs where we are working. When the proposed new Marine Protected Area, Tun Mustapha Park MPA is finally gazetted then we hope to witness an increase of fish life as the overfishing is brought under control. With sustainable fishing, we should eventually see an increase in small sharks numbers. We hope that a demonstration of the value of community action such as our SGP/GEF project near the Tip of Borneo (Simpang Mengayu) will lead to more projects around the region using the techniques we are developing to improve and rebuild the reefs close to each village.

The whole assembly of the shark cave reefs is fixed to the sea floor by glass bottle reefs attached to each corner. Because of the size the reefs were assembled on land and then taken underwater in pieces. The various parts were put back together and large cable ties were used fix all he components into place. The area of seabed chosen has considerable wave action so the reefs were staked to the seabed using steel rods. A total of 12 shark cave reefs were made and positioned in three different areas.

The finished shark cave reefs look suitable for lobsters as well as bottom living sharks, only time will tell which marine creatures take up residence.

Crate reefs were filled with cut pieces of plastic to make many small spaces.  The plastic was recycled from the trash on the beach.  The crate was bedded into cement to make it heavy and to hold everything together.
