What passive (preferred) or active control techniques are there to control a large invasive alien arboreal day gecko (Phelsuma grandis – reaching 30 cm or 12 inches long) in a semi-natural habitat, without negatively impacting smaller endemic arboreal Phelsuma geckos (half its size)? Are there any size selective traps or models someone may have tested and found useful in this kind of situation?
you could invent one based on the difference in weight? triggering a trap with ta certain threshold. Or maybe just have a trap that catches both, but a mesh size that lets the smaller one out?
Thanks Sogy, great to read from you! Long time! Hope all is well your side? The mesh size option seems the better and easier and I was wondering whether anyone had already designed a model and tested it, but I guess the situation I described may be too rare and I'll have to design one myself. All best. Vinnie.
Hi Vincent, I suggest you ask Nik Cole from MWF/Durell. Regards. Gerard
Thanks Gerard. Hope all is well your side. Cheers. Vincent
Hi Francois, you could contact the Aliens-list of ISSG as well, to see if others have advices. Regards, Piero
Hi Piero, Thank you for your suggestion. Cheers. Vincent
A funnel trap modified for arboreal use would probably be a good bet. Both species will be captured live and you can release the natives. Good luck! -Alex
