It is pretty simple preserve, but the kids could get up close to pretty good sized iguanas.
The Anegada iguana is amongst a group of iguanas that are the most endangered on earth. So, a small sacuntuary was created in the Settlement to help breed and preserve the native lisards.
It's pretty interesting as is the restoration of the flamingo population which has been a remarkable success so far.
Here is a link to their site that describes the recovery plan: http://iguanafoundation.org/wp-content/uploads/2014/07/Anegada_Iguana_SRP_2006-2010.pdf
