Greetings @depressedfuckup. In my country iguanas were very abundant. You could find them in squares, backyards, not necessarily in a nature reserve or protected area. But thanks to their ease of hunting and lack of controls, their population has decreased considerably.
I don't like iguanas because of their appearance and as you say, they are a wonderful creation of nature and indispensable for the balance of ecosystems. Thank you for your nice comment.
