Benefits and costs of additional investment in wilding conifer control

Prepared for the Ministry for Primary Industries on behalf of the National Wilding Conifer Control Programme.

This cost-benefit analysis (CBA) was undertaken in conjunction with Landcare Research to estimate the costs and benefits of controlling the spread of wilding conifers across the country. The CBA utilised geospatial modelling to analyse the impact of the control options proposed on the spread of wilding conifers across the country, and the consequent costs in water yields, productivity of agricultural land, fire risk, biodiversity, and cultural values from enabling wilding conifers to spread.
