Bulimba Creek itself is currently impacted primarily by urban and industrial development. In the past the creek corridor was extensively cleared for cropping and then grazing in the early part of the last century with some remnant vegetation remaining. In some areas the reduction in rural industries has allowed riparian vegetation to regrow .
Known as the B4C, the group is involved in protecting and rehabilitating waterways, corridors, remnant bushlands and wetlands. It was the first urban Queensland group to win a State Landcare award in 2000 . In 2005 the B4C won the prestigious Thiess National Riverprize . Recent successes in protecting the envirornment by the B4C include securing the Weekes Rd, Carindale Bushlands and Oates Hill Reserve from the State Government, sving the Wishart Bushlands from development , saving the Bulimba Creek Oxbow and negotiating a major rehabilitation project to restore this saline wetland of 30 ha .
The B4C has its own foundation "the Bulimba Creek Environment Fund", which provides small grants to members of the community to get involved in environmental issues, education and training. B4C has its own catchment centre and community nursery and is in the process of moving to the old Carindale Nursery, now owned by Powerlink. It intends to set up the Southside Sustainability Centre there and place a sustainable small home there for its volunteer centre and offices. Permaculture gardens and food forest zones and community nursery will also be developed.
Karawatha Forest is the reserve with the highest number of species and has five different species of Glider Possums. It also has a fauna overpass constructed over the four lane road, along with underpasses, rope ladders and exclusion funnelling fencing. The project was undertaken by The Griffith University Fauna Unit and Dr Darryl Jones.
