Re: Do you need permission to collect aquatic plants? Sorry, I realize this is a late reply, but no one gave you a very good answer. Most of the specific examples dealt with Texas, which has much less restrictive laws than most states.
Plants belong to the landowner, and you must have landowner permission to legally collect plants. You can just ask the landowner in most cases, but state and national parks have a formal permit application process. You can get in serious hot water for illegally collecting flora from a park, so don't do it!
Of course you can also get in trouble for collecting a state- or federally-protected species, even with landowner permission. Familiarize yourself with any protected wetland species likely to occur in the area before you go out collecting.
Fish and game agencies typically do not concern themselves with plants. Most states have a Department of the Environment, Dept. of Conservation, or similarly named agency that handles flora, invertebrates, etc.
Also be sure to collect responsibly! If you only find one or two individuals of a species at a site, please don't take them, and try to minimize damage to the habitat while collecting. Many species can be propogated from seed, so that is an option for uncommon plants. |
