Dama wallaby control
The Uretara Catchment is 4100 hectares and includes the township of Katikati. The total catchment is comprised of approximately 1619ha (39%) indigenous forest, 1528ha (37%) pasture, 697ha (17%) horticulture with the remaining 252ha (6%) being exotic forest and urban.
The Uretara Stream is the principle waterway which is fed by three distinct tributary watersheds; the Uretara, Wharawhara, and the McKinney all flowing to the Uretara Estuary.
The main Uretara watershed is primarily comprised of indigenous forest in the Kaimai Forest Park with a narrow band of pastoral farming and horticulture either side of the river from where it leaves the Forest Park.
The Boyd/Quarry watershed is primarily a modified landscape with only a small proportion of indigenous forest and three tributaries (Wharawhara, Quarry and Boyd streams) each draining a portion of the area. The land use is mainly pastoral dry stock grazing in the steeper landscape towards the Kaimai Forest Park and becomes dominated by horticulture in the lower terraces and rolling landscape. Until early 2018 a dairy farm operated in the lower part of this watershed though this has now converted to dry stock farming with additional conversion to avocados being planned on this property.
The McKinney watershed is also highly modified with little indigenous forest. The dominant land use in the McKinney is dairy with some dry stock grazing and horticulture. N.B. The McKinney watershed does not contribute to the water quality at Henry Rd Ford as it enters the Uretara downstream of the swimming hole and monitoring site at Henry Rd Ford.
The Henry Road Ford bathing site in the Uretara catchment is ranked as one of the highest risk bathing sites in the region, according to 2016/2017 Recreational Waters Surveillance Report (Scholes 2018). Results collated between 2012 and 2017 report a mean Escherichia coli concentration of 478cfu/100mL, which sits between the Alert/Amber (260 cfu/100mL) and Action/Red (550 cfu/100mL) thresholds set in the Microbiological Water Quality Guidelines (MWQG) (MFE 2003).
In response to the Recreational Waters Surveillance Report, an investigation was designed to gather a more in-depth understanding of the E. coli issue within the catchment and direct the focus of mitigating actions. The objectives of this investigation were to determine; where the E. coli loads might be coming from within the catchment, if any patterns could be seen in regard to weather and flow patterns, and identify the contributing animal sources (Human, Ruminant, Canine, and Avian) via faecal source tracking (FST).
This investigation found:
Two localised contamination events at Henry Rd only showed strong avian signal. This indicates bird populations in the lower catchment can impact water quality at the swimming hole without input from the wider catchment.
This investigation found:
Landowners can take action now. Regional Council offers practical advice and increased funding grants to help landowners within focus catchments to complete works that can contribute to improved water quality.
Funded works can include fencing, planting, nutrient budgeting, farm planning, detention bunds, treatment wetlands and many other activities. We can also help landowners to access funding from the Te Uru Rākau One Billion Trees Programme.
These incentives are for a limited time only.
