the park is set in the karri forest, an ecosystem unique to this part of the world. growing up to 90m tall, making it one of the world's tallest hardwoods, the smooth barked karri (eucalyptus diversicolor) is a majestic tree which will dwarf you as you walk beneath its canopy. the loamy soil also supports large colonies of moss and plants such as the swamp peppermint (agonis linearifolia), hibbertia, karri hazel, water bush, myrtle wattle (acacia myrtifolia) and lemon-scented darwinia (darwinia citriodora) all of which thrive in the damp conditions. although the dominant species here is karri, there is a beautiful stand of pure marri (corymbia calophylla) north of the falls, and jarrah (eucalyptus marginata) is also dotted throughout the park.
