Coral Line by: Karen & Christopher Stewart

Coral Type: Digitate

Coral species: Acropora humilis

2 yr update: WOW! This line is amazing! 
The coral bleaching event induced by El Nino occured in April 2016, so your line was left in the nursery to wait out this event. Transplanting to the reef would have caused unnessecary stress. We believe we made the right management decision as the line, following bleaching, has recovered well, with 100% survival! On our reef, this species can no longer be found, as all were killed in the bleaching event. This means your line is so important for re-seeding our damaged reef! Apologies for not updating the graph- we are backlogged with data collection but will get round to it as soon as we can. For any questions, please email deborah.burn@gili-lankanfushi.com

Coral Line by: Matthew Larrabee

Coral Type: Digitate

Coral species: Acropora secale

Note: Another line showing exponential growth rate. With time the rate of growth increases, showing that more energy is put into growth during the second 6 months. An interesting line that, along with other lines containing the same species, has survived well. 
The corals are certainly ready for transplantation, however in November we are expecting a strong El Nino event here in Maldives. This will cause a rise in sea surface temperature and can severely stress the corals. We believe they have a better chance of survival remaining in the nursery than on the shallower reef. For this reason, we will postpone transplantation until December time. We are excited to get them on the reef, but ultimately their survival during this concerning time is key.
2 yr update: The El Nino event occurred, but contrary to our predictions, it occurred in April 2016. We left your line in the nursery for this event and are pleased we did, as the survival rate is still at about 90%. This was one of the strongest lines during the bleaching event, where locally on the reef, this species can no longer be found. This line is now such an important one for re-seeding our damaged house reef. You will see from the photograph that the line is so heavy, we had to cut it out the nursery and drape it over the frame as it was causing our first nursery to collapse inwards! The new transplant date is set for March 2017. Apologies for not updating the graph, we are backlogged with data collection, but will get round to it.

Message: "Happy Reef to you! Good luck growing!"

Coral Type: bushy

Coral species: Pocillopora damicornis


Note: This coral has shown an exponential growth rate (where the rate of growth increases with time) and it will be interesting to see if this is the same for other species. With this spherical growth form, one of the issues in our methods is highlighted- Our measurements only show linear colony diameter, where in cases like this, it would be more accurate to measure a 3D volume increase over time, or weight.
Normally found in shallow rocky habitats, this line has showed an incredible survival rate! The corals are certainly ready for transplantation, however in November we are expecting a strong El Nino event here in Maldives. This will cause a rise in sea surface temperature and can severely stress the corals. We believe they have a better chance of survival remaining in the nursery than on the shallower reef. For this reason, we will postpone transplantation until December time. We are excited to get them on the reef, but ultimately their survival during this concerning time is key.
2 yr update: The El Nino event did occur, however it came later than originally predicted, and occurred in April 2016. We left the line in during this time, and we are please to have made the right management choice. The line was impacted somewhat, where partial mortality seems to have occurred for some of the colonies. All colonies are still mostly alive though, and we look forward to their new transplant date of March. Apologies our graphs have not updated, we are working on this.

Coral Line by: The Bork family

Message: "Happy Reef to you! Good luck growing!"

Coral Type: Branching

Coral species: Acropora sp.

Note: This line has grown steadily over the year, and has a strong survival rate. These pictures are interesting because we can see the difference in growth rate between this species and the species growing either side (Acropora aspera) which grows much faster! The corals are certainly ready for transplantation, however in November we are expecting a strong El Nino event here in Maldives. This will cause a rise in sea surface temperature and can severely stress the corals. We believe they have a better chance of survival remaining in the nursery than on the shallower, warmer reef. For this reason, we will postpone transplantation until December time. We are excited to get them on the reef, but ultimately their survival during this concerning time is key. For more information see our page '2015 El Nino'.

2 year update: We are sorry to report that this was one of the lines which died during the El Nino event of 2016. The event occurred later than we expected, and the warming period in April 2016 caused the colonies of this line to bleach and die. To learn more about bleaching see our new bleaching page. Unfortunately, all of the lines of this species died during the bleaching event, both in the nursery and on the reef! Whilst this line has died, it's data will be used in our research. For any questions or if you wish us to plant you a new line, please email me on deborah.burn@gili-lankanfushi.com
