Sandstone communities may provide areas of high species and ecosystem diversity

Rainforests are defined by their vegetation associations and are resource centres for a variety of faunal taxa that are either directly linked to rainforests or are more widely ranging species that are dependent on them.

All the rainforest patches studied to date have endemic earthworm and Camaenid land snail species associated with them.

Eucalyptus ceracea is endemic to the subregion.

Acacia hypermeces, is only known from the mouth of the Berkeley River.

The subregion is fox and rabbit free and essentially uninhabited.

The anomalous high, vegetated coastal sand dunes near Cape St. Lambert at the mouth of the Berkeley River. These reach 90 metres in height.

"Dry" rainforest patches, as well as swamp rainforests provide dry season refuges

Mangroves

Further research is required to define the extent to which this aspect may apply to sandstone country because of its ability to provide fire protection.

All the rainforest patches studied to date have endemic earthworm and Camaenid land snail species associated with them.

Airfield Swamp on the Mitchell Plateau is a large perched paperbark forest wetland.

The flora and fauna of northwestern margin appears to be still intact.

There is tropical laterite flora. In particular the Livistona eastonii palm community, a palm dominated landscape, is unique in Western Australia.

Critical weight range mammal fauna persist in this subregion.

Middle Osborn Island is a volcanic plug.

The Prince Regent Lineament encompassing the Prince Regent River.

A sunken coastline with extensive coastal archipelagos from the Buccaneer Archipelago to Sir Graham Moore Island. These islands form a microcosm of the subregion and present an opportunity to protect intact ecosystems.

There are animals of special interest.

The subregion is fox and rabbit free and essentially uninhabited.

Mound springs and swamp rainforest.

The Cape Bougainville rainforest on laterite and volcanic surfaces has no hoofed feral animals and is the largest single patch of rainforest in the Kimberley.
