Barratta Creek Wetlands

From Dry Tropics Wiki
Jump to: navigation, search


Although its flow regime through the lower half of the catchment has been significantly modified from seasonal to perennial due to tailwater discharge from irrigated cane farms, the Barratta Creek subcatchment is one of the most important, healthy and productive creek systems in the Burdekin catchment. It includes many large, permanent wetlands and long lengths of perennially-flowing creek. Unlike most other coastal creek systems in the region, there are no major fish passage barriers. Riparian habitat condition is generally good though threatened by weeds and inappropriate fire management. Tributaries such as Pelican Creek and the Collinsons Lagoon systems are in very poor condition, with loss of riparian vegetation and domination by aquatic weeds, but are worthy of rehabilitation. The lower catchment includes wetlands listed in the Directory of Important Wetlands, and as part of the Bowling Green Bay National Park and Ramsar site.
