Exemptions in other programmes also apply to projects involving public safety, sustainable timber harvesting and for small projects (Crowe and ten Kate 2010, DPCD, 2013). If a sector is not covered by an offsets programme, policies should be developed to help minimise its net biodiversity impacts, consistent with contributing to the delivery of a jurisdiction’s broader biodiversity objectives. In the US Compensatory Wetlands Mitigation programme, the overwhelming majority of the 70 000-80 000 annual applications have low risk to biodiversity.
