Auckland’s natural environment is central to the health and wellbeing of the region’s people, cultural and spiritual identity and economic success. Continuing biodiversity loss is an ongoing challenge for Auckland. In a region of 500,000 hectares, less than 30 per cent of Auckland’s original native vegetation cover remains. Over 50 per cent of the remaining native vegetation is on private land, along with some of Auckland’s most threatened ecosystems and species.

Introduced pest animals compete with native birdlife for food and habitat, eat the eggs and young, and attack adult birds. Pest plants smother and displace native plants and ecosystems. Effective pest control has the biggest impact in protecting native species.

This report contains a high-level analysis of the likely economic costs and benefits associated with two proposed investment options relating to Auckland Council’s Natural Environment Targeted Rate for the 2018-2028 Long-term Plan (LTP). Expenditure on the natural environment in the LTP is based on planned activities that will occur according to the Regional Pest Management Plan which has eight outcome/investment areas. These include expenditure in both terrestrial and marine environments. In addition the LTP includes investment in marine ecology and the Pest Free Auckland initiative.
