Our Environment

At its heart, the Mangatangi Maramarua Catchment is a community-led group that recognises the importance of collective effort over individual action. Learn about our catchment area’s biodiversity, water quality, and pest control measures.

Our Catchment

Our catchment is defined by the rivers and streams that flow within its 19,500 hectares. It lies at the foothills of the Hunua Ranges, a 250 square kilometre mountain range which is home to 14,000 hectares of native forest and is bordered by the Firth of Thames to the east and the Whangamarino Wetland to the West. Whangamarino is an internationally recognised wetland (Ramsar site) and the second largest in the North Island.

Biodiversity

The area comprises of pastoral farmland, extensive native bush, pine forests, wetlands, waterfalls, streams, and rivers. The catchment supports a variety of native birds and plant species. The rivers and streams are home to an array of native species, while the wetlands provide a crucial habitat for birds and plants.

Water Quality

Understanding the health of our waterways is crucial for improving water quality and sustaining a healthy environment. We have established monitoring sites to collect comprehensive data on water quality. This data allows us to benchmark our results against national and regional standards, providing a clear picture of our current water health. The insights gained from this monitoring will guide our strategies and actions to enhance water quality, ensuring positive outcomes for the next 25 years and beyond. By continually assessing and adapting our approaches based on the latest data, we are committed to fostering cleaner, healthier waterways for future generations.

Pest Control

Effective pest and predator management is a key component for maintaining the health of our biodiversity. We conduct pest surveys of the area, designed to inform and develop a catchment-wide pest strategy. Understanding the level of pests within the catchment is key to understanding the level of threat they pose.
