Rotted exterior shutters???

I have shutters on the exterior front windows and they are 10 years old and have began to rot on the bottom. I would like to cut off the bottoms and replace it with the same wood. Does any body know what type of wood this is? Its a little over a 1/2 inch thick. The picture upload is very confusing so i added them to photobucket. hopper28755's Library | Photobucket (http://s1028.photobucket.com/user/hopper28755/library/) Thank you
