Marine ecology

Marine wetlands include the area of ocean from the coastline to 6m below the lowest astronomical tide. Due to difficulties in establishing a 6m contour, marine wetlands in the Queensland wetland mapping includes marine waters to the jurisdictional limits of Queensland waters (3-nautical-mile limit).

Some areas, such as the Great Barrier Reef in North Queensland, are world renowned marine wetland areas and attract visitors from all over the world.

Queensland Intertidal and Subtidal Classification Scheme

The Queensland Intertidal and Subtidal Ecosystem Classification Scheme uses the biological, physical and chemical characteristics of the water column and sea floor to classify intertidal and subtidal ecosystems, which includes estuarine and marine environments. The scheme develops a common understanding and language of classification to improve communication and lead to better management outcomes. It provides a structured framework and understanding available for mapping.

Module 1—Introduction and implementation of intertidal and subtidal ecosystem classification is split into two parts. Part 1 of the module introduces the classification scheme, outlines key principles and concepts, and describes how the scheme was developed. Part 2 of the module describes the process of implementing the scheme, including how to develop a classification system, creating a typology, and mapping the final outputs and ecosystem types.
