Water facts

Harpley’s unique series of wetlands and interconnected lakes are part of an important water system.

A wide variety of plants and animals live in this ecosystem, while native and migratory birds are a treat for birdwatchers!

Find out more about how these water systems work and why it is so important to keep them healthy on the Harpley Discovery Trail App and nature trails.

70-75%
of the Earth’s surface
is covered with water.

Of that figure,
just 1% is fresh water.

This places a strain on waterways such as rivers
and lakes.
