Biodiversity Natural biological diversity is maintained or enhanced at the landscape level. Adequate levels of biodiversity are essential to the maintenance of agricultural production systems, healthy rivers, soil and clean air. Diverse biological systems may also offer valuable alternative streams of income for rural communities. A range of possible targets was considered and relevant technical staff were asked to consider the validity of proposing a target, in their area of expertise, that would meet the above criteria. Using the information and recommendations provided by the technical panel the following preliminary Catchment Targets have been proposed and circulated for comment - End of valley salinity target.
Acid soils target.
