In this newsletter we had hoped to be able to tell you about the release of the tortoises on Silhouette. We were going to tell you how, with your help and support, together we had contributed to restoring the biodiversity in our newest National Park. Unfortunately this is not to be and we have a major upheaval to report instead.
We arrived back on Silhouette early in December at the end of a difficult year of cancer treatment for Gill in the U.K. Two days later we were shocked to receive notification from Islands Development Company (the government company which manages Silhouette) that they wanted us out of the buildings and off the island by the end of that month. We appealed to both the Vice-President and the Minister for Environment to have this decision reversed, but had no useful response for six weeks. Eventually, on 25th January, a meeting was arranged with IDC and the Ministry of Environment to try to resolve the problem of our sudden eviction from Silhouette. The upshot of this is that we were given a further two months to pack up and leave however, the real blow is that both IDC and the Ministry of Environment made it clear that they do not want tortoises on Silhouette. We have been told to find other homes for our huge family of 166 beautiful, gentle giant tortoises.

Our giant tortoise conservation project has received some very welcome and positive publicity this year. A full page article in the travel section of a major German Sunday paper, with a wonderful portrait of Adam illustrating the article, was followed in May by an article in similar vein in the French paper "Var Matin", which was sent to us by Bernard Devaux from Le Village des Tortues at Gonfaron.
Judging by comments made by visitors to the tortoise enclosures, the television film made by SWR-TV back in 2002, has been re-released a number of times across Europe. This half-hour-long programme was made at the time of the first successful hatching for the project. In May this year, a Spanish TV crew spent ages filming the tortoises and recorded interviews about the project and our other conservation work. This programme was broadcast in July and was well received by at least one viewer who wrote immediately afterwards to say how fascinated he was.

The end of 2009 proved to be a busy time for us, thanks to Josephine. She produced 4 clutches of eggs in the year, one in May reported in the last newsletter and then a further 3 in June, July and September. This is a record number of clutches for Josephine and not surprisingly a record number of eggs – 77 in total. Her eggs have always had low fertility or low hatching success so we did not expect 77 babies but were hopeful that we might get a reasonable number to add to the existing 23 Dipsochelys hololissa juveniles. By the end of the year three of her clutches had hatched, with the last one still in the incubator. Fortunately their fertility was higher than in any year so far (54%) and hatching success was also reasonably high and 26 hatched successfully. We now have 49 juveniles of this species. The last clutch is still incubating and could hatch at any time. Fertile eggs usually change from being pinkish to a bright white as the embryos develop and affect the structure of the shell. Very few of the last clutch have done this so we are do not expect many to hatch, but even one more hatchling would mark a milestone for the project.

Predictions of a sharp decline in visitors to the islands and Silhouette in particular have fortunately, so far, proved to be wrong. The project has seen a steady stream of visitors who have kept us busy – so the delay in sending out this newsletter is not because we have been sitting under the palm trees, drinking beer, rather that we have been kept on our toes these last six months. An added bonus came our way because of the troubles in the Indian Ocean – political upheaval in Madagascar and the dreaded pirates from Somalia meant that we had unexpected visits from a number of cruise ships. This was also a surprise chance for some parents of adopted tortoises to visit the project and see how their once little tortoises have grown.

We had anticipated sending out a Tortoise Newsletter in late September, but with each week that went by and none of the eggs showing signs of hatching, we decided to wait until Josephine’s second clutch was due to hatch. That time is on us now and we wonder if these eggs are also infertile.

It seems such a long time since we sent out a Tortoise Newsletter - please accept our apologies for this lack of news. In December Josephine and Adam (Dipsochelys hololissa) produced 5 more hatchlings, bringing the total number of their offspring up to 20 and the total number of baby tortoises up to 150.

We have held back with this latest newsletter in the hope that we would have some good news about new hatchlings. Unfortunately it has turned out to be a very unproductive year.
For the first time in 10 years, Eve had laid one proper egg which, as one might expect, was not fertile. Josephine on the other hand surprised us with three clutches, totalling 51 eggs. Much to our dismay, all except two of these were infertile and both fertile eggs stopped developing (one very early on and the other probably after 8 to 10 weeks). One clutch of 17 eggs is still in the incubator, so there is still a chance.

Last year Josephine, our only fertile Dipsochelys hololissa female tortoise, took a year off – no eggs, although she was seen “turning”, tearing up the grass in preparation for nesting, but never actually dug a proper nest and laid no eggs. This season, in May, she obligingly waited until we had returned from a short holiday. Four nights after our return, during which she had spent two of the four nights “turning”, she produced a clutch of 13 eggs. These are the first eggs for this season. We miss the constant supply of eggs from Alida who was released into the wild in December but we have so much work looking after her 125 babies that it is a relief that the incubators are not full of her eggs!

Clear skies and a light breeze augured well for this day we had been working towards for the past nine years. The tractor and four strong men were on standby, the small island workboat was tied up in the harbour and the schooner “Sea Shell” was lying at anchor beyond the reef. On board, breakfast was being served to members of the BCG and NSV and three adoptive “parents” of our hatchling tortoises.
On shore, five Dipsochelys arnoldi tortoises were being hoisted from their enclosure and put into the tractor trailer. Hector and Adrian, who had obligingly waited next to the fence, were loaded first, followed by Clio and Alida. Stan – all 200 kilos of him – remained immersed in his wallow at the far corner of the enclosure and had to be coaxed onto dry land and across the enclosure with the promise of slices of apple – a rare luxury on a tropical island!

The onset of the south-east tradewinds in May brought us some relief from the blazing heat and humidity of the doldrums. What had seemed like a labour of love, collecting fresh leaves for 137 baby tortoises twice each day, finally returned to a normal daily activity.
Adam, Christopher and Stan, the three largest males, have finally realized that the mating season is now over and that the females are no longer responding to their love songs. Phoenix, the youngest of the Dipsochelys hololissa males has suddenly discovered that he needs to approach the females from behind if they are to take notice of his noisy advances. For two years he has been sidling up to the ladies and making advances head to head! Having learnt his lesson he must now wait until next season to make a real impression.

We delayed sending out this issue of Tortoise News so that we could bring you news of the latest hatchlings. Josephine and Adam (Dipsochelys hololissa) have produced a record five hatchlings. Our very first hatchlings – now 5 kg. heavyweights – came from Josephine and she subsequently produced only one, and then two hatchlings. So, five is a big increase in her fertility and we have another clutch due in December.
Alida, who must hold some sort of record for tortoise fertility, surprised us in March when she laid a clutch containing only one fertile egg. This was compensated for by the next clutch of 13 eggs of which only one was infertile!

Our Dipsochelys arnoldi female tortoise, Alida, came to the rescue this month with the first clutch of eggs for this season. She has rescued us from the embarrassing situation of having more requests for the adoption of baby tortoises than babies to adopt. The rush of adoptions came as a result of visits to Silhouette by the cruise ships Hebridean Spirit, Island Sky and Le Ponant. Our inclusion on these and other voyages around the Indian Ocean as lecturer/guides gave us the opportunity to promote the "Seychelles Giant Tortoise Conservation Project". The guests on these cruises were very generous and we were overwhelmed by their support. Indeed, Hebridean Spririt brought back the Ferriers and the Frosts, adoptive parents from last year who had never seen their babies as the ship had been unable to land passengers due to the heavy swell. On board also was Stephen Cork who came to visit Noyna and see how she had grown in a year. Noyna performed so well that Stephen adopted another baby and named it Boulesworth - a pun may be intended.

The close of 2004 has been very dramatic and we are grateful for everyone's concern. Fortunately for us the tsunami had spent most of its force before reaching the western Indian Ocean. Seychelles experienced some flooding and damage to roads and bridges on Mahé but no loss of life. On Silhouette there was a notable tidal surge which continued for several hours, but it was not enough to breach the beach crest. This was just as well as removing all the tortoises to higher ground would have been quite a job.
