Landscapes of the Burnett Mary encompass a complex distribution of soils. This is the result of a long history of interactions between climate, geology, topography and the biological cycling of material between plants, animals and micro-organisms. Apart from narrow strips of young alluvium deposited by rivers and streams, and coastal sand-mass deposits, the majority of the region has comparatively old undulating to hilly landscapes.
Effective land management practices and adoption of industry Best Management Practices (BMPs) are central to the future health of soils and land condition. Both rely on a clear understanding of landscape and soil processes. In turn, healthy soils and landscapes will maintain soil/land productivity and avoid degradation. Reducing fragmentation of agricultural land and avoiding land use conflict is critical to maintaining the long-term economic viability of productive soils.
Ultimately, improving land condition through effective planning and innovative/adaptive management, particularly with respect to climate variability, will enable:
- continuing agricultural production
- biodiversity conservation
- functioning of ecosystem services
- supported urban development
- sustainable, mineral and gas resource extraction
- improved surface, ground and marine water quality.
For the purposes of the NRM Plan, soil types have been grouped on the basis of inherent similarities in chemical / physical properties and aspects of management, into Soil Management Units. The Burnett Mary’s soil management units are:
More detailed description of these units, their distribution and predominant land uses is available in the Background report – Land and Soils.
