Biodiversity

Wildlife is abundant here at Yanchep National Park. It’s an important conservation area on the Swan Coastal Plain, containing seven vegetation communities, four wetlands and over 450 cave systems.

Some of these cave systems were deposited as marine sediment around 600,000 years ago! They provide an ideal environment to life-forms living underground, including amphipods, a threatened species of invertebrate.

Wetlands are a key feature of the park, with three (3) lakes (Loch McNess, Yonderup Lake and Wilgarup Lake) and two (2) swamps, one within Ridges State Forest and Pipidinny Swamp, close to the south-west boundary.

To birdwatchers’ delight, the wetlands are home to plenty of feathered friends. Waterbirds including swamphens, pelicans, little black comorants, grebes and banded stilts can be seen on the banks and waters of the lakes.

Up in the trees around the park are endangered Carnaby’s black cockatoos, magpies and galahs. Smaller birds including kingfishers, wrens and honeyeaters can also be seen here – and that’s just naming a few!

Visit Yanchep National Park early or late in the day and you’ll almost certainly see a mob of western grey kangaroos. Take a stroll down the aptly named Koala Boardwalk and try to spot a furry koala munching on some eucalyptus leaves.

The trees in the woodland areas of the park are predominantly paperbark, banksia, jarrah and sheoak. It’s also one of few remaining places where tuart trees can be found growing in significant numbers.

In late winter and spring, Yanchep National Park blossoms with spectacular wildflowers including wattles, parrot bush, yanchep rose, catspaw and kangaroo paw bloom.

  • <p>The koala boardwalk at Yanchep National Park.</p> <p>This photo was taken at the start of the Koala Boardwalk. There is a cream and red brick pathway leading onto the brown wooden decking of the boardwalk. To the left of the pathway, there is a thick tree trunk that extends high into the sky. It has been cut off at the top and does not grow leaves. The stump has been turned into a sign with a carving at the top. There is a thin line circling the stump carved towards the top of the stump. Underneath this, a circle has been carved and painted orange. Inside the circle there is a carving of three gum leaves that have been painted green. Underneath the circle is another thin line circling the stump. The stump has large orange letters attached, that spell “Koalas” in capital letters downwards. They are painted orange. </p><p>There is another red and cream paved pathway to the left. The area is surrounded by dirt garden beds that are covered with brown dying leaves, patches of yellow sand and light cream and grey rocks.
