Continuing with my little series on biodiversity, here is a photo of a tree that has what appears to be barnacles on its truck. I don't know the type of tree this is or why it has this adaptation. In North America, it might be to discourage bears from climbing the tree, but we don't have bears in Costa Rica. We have sloths and monkeys that climb trees. This would make an ideal tree for a bear to scratch his back.
This week we are showing photos of the Spanish colonial architecture of Grenada, Nicaragua on our Viva la Voyage travel photo site.
