Lake Ohia
A short detour off the main road will take you to this former lake bed, which offers snapshots of the past, showing visible effects of gum-digging and featuring ancient remains of a once thriving kauri forest.
Features
Stumps of kauri trees uncovered by the
draining of Lake Ohia
Gumlands consist of shrub-covered, flat to rolling land mainly found in northern New Zealand, which have deposits of kauri gum.
Most remaining gumlands are centred in Kaitaia or Kaikohe. There are a number of layers of kauri logs lying buried in many parts of Northland. Preserved in swamps, these logs can reveal the fate of previous generations of kauri forests, tens of thousands of years ago.
History
In the late part of the last century, gum diggers made their presence felt in the Far North. Armies of fortune seekers settled just south of the area and hunted for a bounty of kauri gum. The fossilised resin from the kauri tree had become highly desirable as the backbone of varnish manufacturing.
Lake Ohia was drained for gum-digging. On the former lake bed you can now see exposed remains of the fossilised kauri forest that was drowned about 30,000 years ago, before the lake was formed.
Plants and animals
Water is present for approximately two months of the year. Classified as a gum-field wetland, this former lake now provides important habitat for rare ferns, mosses and orchids.
Signage at Lake Ohia
The surrounding swamps and shrub land contain the threatened freshwater black mud fish and are home to many bird species.
Location
Lake Ohia is located on the Karikari Peninsula, a 40-minute drive northeast of Kaitaia.
Getting there
From Awanui drive east for approximately 15km on SH10 and then turn onto Inland Rd. You find Lake Ohia just off Inland Road.
