Fitzgerald River National Park: This time we are moving away from NSW and describing a National Park in Western Australia. Fitzgerald River National Park has an area of 240,000 hectares and follows the southern coastline west of Esperance. A wealth of plants is found in the Park. Over 1800 flowering plant species have been identified. This represents nearly 20% of the native plants found in Western Australia. Sixty-two species only occur in Fitzgerald River National Park. Hakea victoria and Regelia velutina (see photograph) are two of these endemic species. The rare Western Whipbird and Ground Parrot are two rare birds found in the Park. Also within the park are a series of isolated peaks known as the Barrens. Matthew Flinders named them in 1802. The park is also known for its spongelite cliffs. This soft rock was formed more than 36 million years ago. Sponges proliferated in the warm shallow sea, which covered the area. Their silica skeletons gave rise to the name of the rock type. A road traverses Fitzgerald River National Park and provides access to picnic areas and walking tracks.
