Designing a Natural Capital Approach to Estimating the Full Economic Costs_INNS

The Authority is looking for suppliers who can conduct a comprehensive assessment of the economic costs of INNS not previously estimated, including non-monetised natural capital costs. The approach could be regionally focused (and potentially habitat driven) to be consistent with the 25 YEP and provides comparable value estimates on a per km2 basis. This is important to ensure that the natural capital approach can be complemented by cost-effectiveness analysis to identify the most cost-effective interventions to control / eradicate INNS while also considering restoration costs. More complex analysis may employ various scenarios to identify how a change in the abundance of some INNS (e.g. relative to climate change) may impact both natural capital and the cost of control, through a regional lens.
