"The forest cover on the western slopes of
Mt Ruapehu is patchy, the beech forest sometimes appearing as
'islands' within the red tussocklands and wetlands. The area has
probably been swept with fires in earlier times and forest re-establishment
inhibited because of the bogginess of much of the landscpae. Drainage
is often impeded where there is a sharp change in soil texture,
as can occur when a coarse tephra (such as Taupo Pumice) lies
on finer tephras (such as the Tongariro Ashes)". Legend

Fold of the Land. |
