The Ferlo, in the North-east of Senegal, is the region where the furrowed turtle (Centrochelys sulcata) can still be found in its savage state. The turtle plays an important ecological role in this difficult and harsh region: for example, it digs huge holes to seek shade, coolness and humidity in order to withstand the scorching heat (of up to 48°C under the shade) and to compensate for water shortage during 6 to 8 months of dry season. All the other wildlife, from the butterfly to the jackal then uses these abandoned holes as cover during the hottest periods of the day.
The furrowed turtle is also responsible for the dispersal of many grains. As a very opportunistic herbivore, it eats many varieties of vegetables and rejects, through its faeces, undigested grains which then grow close to the main plant. But the furrowed turtle is under threat. Its populations are limited and vastly spaced out one from the other thereby eliminating the opportunity of meeting and reproducing the specie. In addition, constant negative impact of human activities on the Sahel worsens the fragile situation of these turtles: desertification, overgrazing, destruction of its habitat and gathering for the illegal sale of exotic animals.
Our champions, thus, decided to act. Since 2006 and through the SOS Sulcata program, they have carried out the breeding and rearing of 24 turtles in a breeding and awareness-promotion centre near Dakar - the Noflaye Turtles Village. The turtles were then released into the natural habitat of the Ferlo. After 6 years of wild life in the Sahel, 80% of the released population is still alive and shows the same habits as the wild ones!
A second group was reintroduced into the same site in June 2011 in order to complete the first group. Twelve (12) newcomers thus discovered the difficulties of wild life. The same strict scientific procedure was used as in 2006: selection and quarantining during several months in Noflaye Turtles Village, genetic and sanitary tests, feeding, strictly controlled supply of water and visits to prepare these turtles for the “adventure”. These 12 turtles were each equipped with a transmitter just like the first group. Regular monitoring can thus be carried out while the team checks on the proper adaptation of each turtle.
To make this monitoring possible, a team of 2 or 3 persons must daily cover the Senegalese forest to observe the habits and the general wellbeing of each released animal. It is also the occasion for observing the animals’ environment daily while monitoring the first group reintroduced in 2006. It is during these daily monitorings that the first baby turtles from the first reintroduced group were discovered. This excellent news once again confirms the interest of the action regarding the conservation strategy of the furrowed turtle.
The expected impacts from this project are multiple. Firstly, it helps to quickly solve the problem of the alarming decrease in the savage populations of turtles in this region of the Sahel through the bolstering of its population. The discovery of several baby turtles is a concrete result that is very promising. Secondly, it helps in raising awareness amongst the local populace on the importance of biodiversity conservation. Indeed, the field team works and lives with the local population that is becoming increasingly involved in this project.
The reintroduction and monitoring of turtles’ project in the Ferlo combined to the “Nature Geniuses competition” and the “Nature outing” will help in preventing the total disappearance of this specie in Senegal.
Lamine Diagne is the local champion that helps turtles regain their wild life. Without this turtle lover, nothing would have been possible. As the person in charge of animals in the Turtles village, he monitors, daily, all his protégées while making sure that the team and the project are properly managed.
Concretely, he ensures that the daily operations of the Turtles village and checks on the health and well-being of the kept turtles are carried out properly. Creating awareness amongst the Senegalese people and negotiating with the authorities are equally part of his functions. Feeding and medical stock management, treatment, meeting with the public and with the children of the village are all part of his usual tasks. On the reintroduction site in the Ferlo, he is a very important negotiator since he serves as intermediary for each party. He is henceforth known in Ranérou for his knowledge on turtles and for his communicative enthusiasm. He is also the intermediary between the Noflaye Turtles village, (about 30km from Dakar), and the reintroduction site in the Ferlo which is about 600km to the North-east of Dakar.
The Katané enclosure’s pond has dried up since mid-January. In preparation for the dry season, the turtles have reduced their mobility.
In January and February, Abou embarked on a tour to the Ferlo with the SOPTOM team and local authorities (National Parks, Water and Forestry departments) searching for wild turtles seen in the early 2000s during the first reintroduction programm. Many burrows were found with the villagers’ help. Some have been abandoned, while others showed recent activity traces. This encouraging news suggests that some of these turtles have been there for 15 years!
We must continue working to preserve the remaining Sulcata turtles in the area, while raising awareness among local communities.
The rain falls have been regular. The usually dry Ferlo landscape has been transformed in a green herbaceous carpet. Furthermore, all the pond basins of the Ferlo are filled with water allowing each turtle to access water and food next to its hole.
Abou had the chance to discover two distinct baby turtles on two following days. They are 3 to 4 years old. These two baby turtles confirm our successful reintroduction of the turtles to the wild life, which we supposed when a month ago we discovered turtles’ eggs. Moreover, the two baby turtles demonstrate their capability to survive in the difficult environment of the Ferlo with numerous predators (jackals, mongoose, birds, etc.).
While we all benefited from a well-deserved vacation, our champions continued their field work. Abdou and the team of "The furrowed Turtle" project monitored the size and weight of the Sulcata Turtles at the beginning of the rainy season. The first rains have filled again with water the dry pond basins of the Ferlo. The Sulcata turtles enjoy the bath in the basins and make their drinking water provisions. The first grass in the dry region of the Ferlo is not only a feast for the eyes but a banquet for the turtles after 6 months of fasting.
We were very happy to discover turtles’ eggs, which is not only an indicator of their successful reintroduction to the wild life but a big encouragement for our conservation strategy of the furrowed turtle in the Ferlo. It’s important to recall, that the furrowed turtle is under threat, while playing an important ecological role in the Ferlo, in the North-east of Senegal. Congratulations to the project team for the passionate work and the results achieved in the protection of our biodiversity!
Dear Ecofund Community, please find below the accounts of donations to the project "The Furrowed Turtle" and its expenditures.

Many THANKS to all contributors!!!
P.S.: The balance of 269 euros will be transfered to the project "Turtle Game", which our champions have already prepared. Stay tuned to our Ecoblog ...
News from turtles monitoring thanks to new equipment (photo, notebook, solar charger etc.) financed by the Ecofund community.
This month there is a change in the program, Anneline Grenouilloux, volunteering scientist who assisted our champion Abu for almost 2 years will soon go back home. Now Abu can count on Anne Emanuelle Landes, French volunteering scientist, for the next two years to continue the program.
Otherwise peaceful, during the time of reproduction the rivalries emerge now between the males engaging in violent combats with two results: either one of the males flee or it ends up on its back.
Our intervention within this time is very scarce but vital. We turn systematically all the males around that find themselves on their backs. This position could be fatale to them: The shell of the male is flatter than the females and turning around by them is sometimes a challenge. Their lungs are squeezed and they can die of asphyxiation or dehydration (as the turtles find themselves exposed to the strong heat during the daytime).
Our team had the pleasure to again find new babies! It’s a proof that the reintroduced turtles have perfectly adapted to their new home and natural habitat.

The tracking of the furrowed turtle continues…
With the rain returning in September the turtles and the other animals of the Ferlo take advantage of the new sprouts.
They prepare themselves for the dry season; eating is one of their main activities. The fat reserves they take on during the rainy season have a vital importance during the dry season. Little by little, the sulcata turtle will be reducing its activities until February and then remain underground in its burrow waiting for the next rainy season. She doesn’t eat or drink for about 6 month.

Thanks to the ONOMO Airport Hotel in Dakar and 4 individual donors from Senegal and Germany, the SOS Sulcata-Team is now able to purchase basic work equipment. The equipment will be used for daily observation of the habits and to monitor the general wellbeing of the turtles, which were reintroduced to their natural habitat of the Ferlo.
Furthermore, the donation will finance nature excursions for Ranérou’s school children to the Ferlo natural reserve and so help create awareness among the young generation about the protection of the biodiversity. A few years from now, they will be the ones to make important decisions for their region and its conservation will be based on the knowledge they have acquired.
The reintroduction and the monitoring of turtles in the Ferlo combined with the nature excursions will help to prevent the total disappearance of the Sulcata turtle in Senegal.
Once again a big THANK YOU to ONOMO Airport Hotel, its guests and to the individual donors from Germany and Senegal!
Our future is green!
In der zweiten Ausgabe des Schildkröten Newsletters (leider nur in Französisch) findet ihr aktuelle Meldungen über das SOS Sulcata Programm sowie Berichte von Schülern der Ranérou Schule über den Naturschutz im Schutzgebiet von Ferlo.
Klickt auf das Bild. Viel Spaß beim Lesen (und Französisch lernen) !
Gemeinsam mit dem Kommandant Gomis und seinem Team, sowie Anneline, können wir nach einer Woche in Katané von der exzellenten Arbeit im Ferlo berichten.
Ich finde, dass das Basislager dem widrigen Wetter gut widersteht.
Wir haben einige - wenn auch wenige - Schildkröten gesehen. Leider haben wir keine Schildkröte aus der letzten Freilassung entdecken können. Anneline meint, entweder ist der Sender kaputt oder der Empfang sei sehr schlecht.
Es gibt Neuigkeiten in Katane: mit der Ankunft einer neuen Lehrerin wurde eine Klasse renoviert und eine Gesundheitsstation gebaut. Außerdem wurde das Naturreservat auf 1.200ha Fläche vergrößert. Das ist hoffentlich nicht zuviel für den kleinen Oryxantilopen, Gazellen und Schildkröten Bestand. Und wir werden hoffentlich erleben, wie sich der Bestand der Tiere in der freien Laufbahn erneuert !
Was die Schildkröten aus Madina und deren eventuelle Wiedereinführung in Noflaye angeht, nach Rücksprache mit Anneline, haben wir uns entschieden dies vorerst zu verschieben, zumindest bis zum Besuch im Schildkrötenzentrum in Noflaye. Das Quarantänegehege in Noflaye sit ohnehin noch besetzt.

Der Ferlo ist eine sehr große und dünn besiedelte Region des Sahel im Nordosten des Senegals. Im Ferlo ist die Spornschildköte noch in ihrem natürlichen Lebensraum zu finden. Die Spornschildkröte spielt in dieser schwierigen, weil wüstenartigen Region eine ökologisch wichtige Rolle: Zum Beispiel gräbt sie kleine Höhlen in den Boden, um ein wenig Schatten, Kühlung und Feuchtigkeit zu finden, um die Wasserknappheit während der 6 bis 8 Monate währenden Trockenzeit zu kompensieren und so der glühenden Hitze zu entfliehen (bis zu 48 Grad im Schatten). Die von der Schildkröte verlassenen Höhlen werden von anderen Tieren des Ferlo, vom Schmetterling bis zum Schakal, als Unterschlupf während der heißesten Stunden des Tages genutzt.
Die Spornschildkröte ist außerdem für die Verteilung unterschiedlicher Samen verantwortlich: Als ein opportunistischer Pflanzenfresser isst sie unterschiedliches Gemüse und scheidet deren Samen unverdaut durch ihren Kot wieder aus.
Leider ist die Spornschildkröte vom Aussterben bedroht: Durch den negativen Einfluss menschlicher Aktivitäten, v. a. durch Überweidung, wird ihr Lebensraum zerstört. Der illegale Fang für die Haustierhaltung bzw. für die Herstellung von Souvenirs aus ihrem Panzer verschlimmert die ohnehin fragile Situation der Schildkröten. Dies führt im Laufe der Zeit zur Dezimierung ihrer Anzahl in der großen Ferlo-Region, was die Fortpflanzungsmöglichkeiten verringert.
Unsere drei neuen Champions engagieren sich mit Hilfe eines wissenschaftlich begleiteten Wiedereinführungsprogramms sowie durch Schulausflüge in das natürliche Habitat der Sponrschildkröte, ihren Bestand wiederherzustellen und zu schützen.
Hilf Lamine, Beidi und Henri die Artenvielfalt des Sahel zu erhalten.
