High Conservation Value Aquatic Ecosystems (HCVAE)

High Conservation Value Aquatic Ecosystems (HCVAE)

What these maps show

Aquatic ecosystems of tropical northern Australia host a unique and diverse range of water-dependent plants and animals. Many aquatic ecosystems in northern Australia can therefore be considered to be of high conservation value.

The challenge for managers is to objectively identify those that should be the focus of strategic investments and actions to protect and enhance these values in an efficient manner.

To meet these needs a systematic approach to the identification and management of High Conservation Value Aquatic Ecosystems or HCVAE is required.
