First the most obvious thing you need to remember is, if there are aggressive or dangerous animals around you then you obviously need to be careful with your things and yourself.
In the summer try not to camp on the beach close to the water. In the summer bears will walk around the beaches and that will be dangerous. Any products or items that can leave off a smell will attract any animals and the items should not be left unattended.
Poisonous snakes are very dangerous too. In the summer try not to camp on the beach close to the water. There are not that many poisonous snakes that you will see except in the zoo.
