Noxious Aquatic Plants
The rule will establish a list of declared noxious aquatic
plants and a list of plant species classified as "species to
watch" which will not be declared noxious at this time. By law,
the ODWC is given the authority (29 6-601) to designate and
declare any aquatic plants as "noxious", if they "may cause
injury to the environment of the state". This proposal would
reduce the risk and prevent the spread of noxious aquatic plants
which are being sold and distributed through the backyard water
gardening trade. Some of these plants could have a detrimental
impact if accidentally or intentionally released in to
Oklahoma's aquatic environment.
