There are a number of different definitions of wetlands in Queensland, mainly due to the manner in which legislation has developed over time. The definitions used in Queensland are available in the Queensland Wetland Definition and Delineation Guideline—Part A. Part B provides guidance on the delineation and mapping of wetlands consistent with the Queensland Wetlands Program definition.
It is not easy to give a clear definition of what wetlands actually are. They are neither just land, nor just water as they can actually be both at the same time as well as being able to be seasonally aquatic or terrestrial.
The Queensland Wetlands Program wetland definition is outlined below.
It is consistent with the Strategy for the conservation and management of Queensland's wetlands but includes 3 points of further clarification on the presence of wetland species and the composition of the substratum. These additional points enable an area to be identified as a wetland for mapping purposes and differentiate it from other areas.
Because of the great diversity of wetlands it is necessary to divide them into broad ‘groups’ or ‘types’. For the purposes of distinguishing these different wetland types, a classification system is required. One of the broader groupings of wetlands is based on systems (marine, estuarine, riverine, lacustrine, subterranean and palustrine).
Queensland Wetlands Program wetland definition:
Wetlands are areas of permanent or periodic/intermittent inundation, with water that is static or flowing fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed 6 metres. To be a wetland the area must have one or more of the following attributes:
