About the area
Located on the Firth of Thames/Tīkapa Moana, the Pūkorokoro-Miranda catchment flows into an internationally significant 8,500 hectare coastal wetland that is protected under the Ramsar Convention.
The catchment is home to around 40 different migratory birds, including red knots and bar tailed godwits that fly from Pūkorokoro-Miranda to Siberia or Alaska (respectively) and back every year. These migratory shorebirds rely on the resting and refuelling areas in this catchment, including one of the world’s finest examples of a rare coastal landform – a Chenier plain – consisting of a series of ridges made up of marine shells.
The shorebird area and habitat at Pūkorokoro-Miranda has been significantly degraded and reduced in size. Water quality is poor due to increased levels of suspended sediment. Much of this has been caused by various productive land uses in the catchment and the highly modified hydrology and drainage system that has been put in place to reduce inundation and flooding for landowners in the lower catchment.
Living Water’s key focus is protecting and expanding the shorebird habitat, reducing sediment loads and connecting on-farm biodiversity via ‘mountains to sea’ blue corridors.
