The Kamahi Loop Track passes through mature podocarp forest for the first 400 metres. An ancient mataī grows near the junction of the loop track. Along the bluff tops, aerial displays from kererū, tūī and korimako/bellbird are often seen.

This is a key site for visitors to observe vegetation recovery and the diverse vegetation of the reserve. The ‘ghost forest’, a monoculture of kāmahi trees, sprang up after fires swept through the area around 100 years ago.

The kāmahi is one of the first trees to regenerate when land has been cleared. It provides a stable environment that allows other species, like podocarp and broadleaf, to mature. Once these species reach the canopy they will out-compete the kāmahi for light and the forest will revert to its original state.
