A river catchment brings many responsibilities into the same landscape: water quality, plants, animals, cultural places and the people living nearby. Rangers in the Perth Hills are working across those connections.

Country Needs People announced Bibbul Ngarma Aboriginal Association as its newest partner on 4 September. Founded in 2022, the association is based on Whadjuk-Noongar Boodja.

Its BoorYul-Bah-Bilya Ranger team cares for waterways, reserves, parks and forest across the Mandoon Bilya, or Helena River, catchment. The work includes ecosystem restoration, monitoring biodiversity, environmental sampling, managing invasive species, cultural mapping and community events.

The partnership announcement describes a catchment-management approach that brings environmental, cultural, social and economic values together with local knowledge. The intention is to develop a model that could inform work in other river systems.

It is an example of ranger activity close to a major city, where caring for Country continues across connected waterways and reserves. Urban and peri-urban places carry cultural responsibilities as well as environmental pressures.

The new partnership provides an opportunity for more people to learn about that work and the Aboriginal organisation behind it.
