The Ahukawakawa Swamp is an area of sphagnum bog in Egmont National Park in the Taranaki Region of New Zealand. It was formed approximately 3,500 years ago and is of particular interest to botanists. Over 260 species of higher plant have been recorded there. The area of the swamp is approximately 1 km2.〔("NZ Topo Map" ). Latitude: -39.2518 Longitude: 174.048. Retrieved 7 January 2015.〕 ==Geomorphology== The swamp sits at an altitude of 920 metres〔("Taranaki wetlands" ). Department of Conservation/ ''Te Papa Atawhai''. Retrieved 6 January 2015.〕 and lies between the main cone of Mount Taranaki and the Pouakai Range to the northwest, which reaches 1,400 metres. It was formed about 3,500 years ago when a lava extrusion and a later debris flow blocked the Stony River.〔〔 This extrusion, which reaches 1,052 metres, lies to the west of the swamp and is known as The Dome. The outlet from the swamp forms the 30 metre high Bells Falls.〔 The area is still subject to geomorphological change. The Stony River was considered Taranaki's best trout fishery until severe erosion and land instability in the river's headwaters from 1997 onwards caused high sediment loads.
