Thats what I tend to do... as long as its a old dead branch that been weathered I don't pay attention to what exactly it is. But there are not any harmful trees around here...... I won't pick stuff up off the ground though. I look for the stuff thats been suspended in the air. Usually dead branches that have yet to fall. I just boil them and toss them in the tanks. Where the shrimp and snails attack the new wood. They don't last very long.... a year at best. They will breakdown slowly, but in my planted tanks this isn't really a problem. Do try to remove the bark as this will rot away very quickly with most types of wood. Also anything you find is gonna float for at least a month, so you have to pin it down... other than that I usually don't worry about it.
