Waitohu Stream
Waitohu Stream is a stream in the Kapiti Coast District, Wellington, New Zealand. It flows westward from the Tararua Range through forest, farmland and past residential areas before discharging into the Tasman Sea at the northern end of the Ōtaki Beach, west of Ōtaki.[1] Course and tributariesThe stream originates in the foothills of the Tararua Range, inside the Tararua Forest Park boundary, east of Ōtaki. It runs generally westward, winding its way through rural farmland and skirting the town's northern area of Waitohu before reaching the Tasman Sea.
EcologyWaitohu Stream and its riparian margins support a variety of native fish, birds, and plant species. The stream provides habitat for longfin eel (Anguilla dieffenbachii), inanga (Galaxias maculatus), and other freshwater fish. Seasonal whitebait runs occur in its lower reaches.[4] The estuary at the mouth of Waitohu Stream provides breeding and roosting habitat for coastal bird species. Pied stilt (Himantopus himantopus), variable oystercatcher (Haematopus unicolor), and New Zealand dotterel (charadrius obscurus aquilonius) are regularly recorded nesting in the area.[5] Migratory species such as bar-tailed godwit and South Island pied oystercatcher also use the estuary as a seasonal stopover site.[6] Wetland and dune vegetation near the stream mouth enhances coastal biodiversity, and the stream corridor acts as a wildlife link between inland and marine environments.[7] Human useThe catchment has historically been used for agriculture, particularly dairy and sheep farming. Recreational use includes whitebaiting, freshwater fishing, and swimming near the stream mouth.[8] Flood management has been a recurring issue for local councils, with engineering works undertaken to reduce flood risk in surrounding farmland and residential areas.[9] Cultural significanceThe stream holds cultural importance for Ngāti Raukawa ki te Tonga, the local iwi. It has been used as a traditional food-gathering site (mahinga kai) and features in local oral histories and place names.[10] Environmental managementRegional authorities and community groups have undertaken riparian planting and streambank restoration projects to improve water quality, stabilise banks, and enhance native habitat.[11] See alsoReferences
