In the Ottawa Refuge, Ohio, Phragmites australis australis grows extremely dense mats of vegetation which can prevent fish and frogs that take shelter and lay their eggs in between aquatic plants. The dense mats of Phragmites australis australis can also decrease the amount of food and foraging space for wading birds.
