This study developed an integrated decision support system (DSS) to assist land managers in taking a long-term holistic approach to integrated land-use decisions. MyLand is a unique combination of existing methods and techniques: meta-modelling calibrated off-productivity surfaces for spatial application, a decision tree for selecting options, multiple land-use analysis, multiple outputs and a mapping interface deployed over the Web. The design provides visualisation of geospatial information and enables multiple stakeholders to contribute to a more collaborative land-use planning process. Techniques to solve forestry modelling challenges have been generalised and applied in modelling pastoral and forestry land-use types. Forestry yield modelling is accommodated by a two-stage approach of spatial modelling of a productivity index followed by meta-modelling output from forest stand growth models. Livestock farming is modelled using the property owner's estimates of livestock carrying capacity of land management units in a whole property stock reconciliation model. The environmental performance of the property is calculated from the land-use type and management regime. A case study is described to demonstrate the use of MyLand and results of user evaluation of the DSS are presented.
