I don't see why these two signs couldn't be placed outside like the others... but if there is another new species after the tortoises that is good.
Though I do wonder whether the translocation of some of the lizards and the toads to CBC is permanent...
@YourLocalZooNerd - yes, but can’t remember which lizard - the two species I saw in there when went were Leptien‘s spiny-tailed lizard and Sudan plated lizard
