Modern Aldabra tortoises from the Seychelles are taking the place of their extinct Mauritian counterparts. If you' ve lost species from an ecosystem, they leave a gap. And a species isn' t just a taxonomic unit. It actually fulfils an ecological role. And I thought, well, we should try and bring back species that could fulfil the same or similar roles to extinct species. It' s definitely going for the cameraman. So what was your biggest fear when you introduced the tortoises to the island? The biggest fear was that they' d eat all the very rare plants, of course, but, you know, deep down I realised that they wouldn' t and we' d actually unveiled all sorts of interesting interactions between the tortoises and the plants. Right from the start, the tortoises avoid eating saplings and stuck to the hardiest adult plants, which can survive a few munched leaves. Oh, the biggest of the bunch. Be careful he doesn' t bite you. The Aldabra tortoises' natural instincts and the native vegetation worked in perfect harmony. |
