| Waimangu Volcanic Valley hosts a wide variety of unique thermal plants in many habitats ranging from acid to alkaline soils, hot wetlands and bare warm ground.
All the thermal plants known in NZ are represented at Waimangu Volcanic Valley.
All the thermal plants at Waimangu have arrived through natural succession since the 1886 Tarawera eruption; that is, there have been no plantings by man.
Birds, wind and the action of the Eruption itself have deposited the seeds and spores here, and these account for the exotic thermal (not native of NZ) species that are present.
Waimangu Volcanic Valley and Lake Rotomahana are good examples of an eco-system naturally re-establishing itself in an area following a volcanic eruption. |
