Working to conserve and restore water quality and wildlife habitat in Perth inner city catchments

Welcome to the Claise Brook Catchment Group

The Claise Brook Catchment Group is an incorporated community-based environmental group working to restore wetlands and improve the quality of water flowing into the Swan River from Perth city and inner city.  The group has been operating since 1997 and meets on a monthly basis.  

We hold monthly working bees, and community plantings in winter to provide habitat and improve water quality in local wetlands and the Swan River.  We assist at the City of Vincent’s Local Plant Sales and hold tours to raise awareness about how everyone can help to improve the health of local wetlands and the Swan River.

In 2014 we continued planting at Hamilton Lakes in Northbridge so we now have two sites that we are maintaining through monthly working bees.  These are held on the first Saturday of each month and we alternate between Robertson Park or Hamilton Lakes.   Activities include weeding, mulching, planting, seed collecting and other activities.

In 2011, with the assistance of Bamford Consulting, we reviewed the impact of proposed city waterfront developments on swan habitat, and in 2008 our members undertook field surveys of all parks and reserves within the City of Perth to assess their biodiversity value.  The information was used to prepare a Local Biodiversity Study for the City of Perth. Visiting artist Katri Walker incorporated our views on the importance of wildlife within the urban environment, and the black swan in particular to Perth city in a video installation which can be viewed online here.

A particular focus is working with various agencies to coordinate a whole-of-catchment approach to improving water quality within the Mounts Bay catchment.  In 2008 we made a submission on the proposed development of Mounts Bay and subsequently facilitated the preparation of Water Quality Improvement Plan (WQIP) for the Mounts Bay catchment.

The contribution that our members make to the local community has been recognised through two awards presented to our group. We received the Volunteer Group of the Year Award in the state seat of Perth in 2001, the International Year of Volunteers. On Australia Day 2009 our group was honoured to receive the City of Perth Premier’s Australia Day Active Citizenship Award for 2009.
