The Northern Slopes Landcare Association (formerly Upper Gwydir Landcare Association) was formed in 1998 to bring together the numerous local Landcare Groups under an umbrella organisation that broadly covers the Bingara, Warialda, Gravesend, Rocky Creek and Upper Horton areas of the Gwydir Shire.
The Association is managed by a committee that is made up of representatives from those areas. It employs two Local Landcare Coordinators, a Regional Agriculture Landcare Facilitator, and the North West Cacti Control Coordinator, who assist the Landcare groups, community groups and individuals to source information on natural resource management and to manage the day to day running of the Association.
The NSLA works closely with the North West Local Land Services and other Government instrumentalities to co-ordinate Natural Resource Management projects within its area.
