This technical report summarises the state of indigenous ecosystems and the environment within the boundary of the Waitakere Ranges Heritage Area Act 2008 (WRHA or Heritage Area), and change within the Heritage Area over the period 2008 – 2012. The Heritage Area covers approximately 27,000 ha and contains one of the two largest blocks of continuous vegetation in the Auckland Region (c. 21,000 ha). The vegetation is characterised by a diverse mix of different native ecosystems. Altogether almost 80% of all the forest, scrub and wetland associations in the Heritage Area have statutory protection that prevents or limits habitat clearance.
A total of 52 different indicators are outlined in this report. In our opinion, these 52 indicators provide accurate indication of the general state of the natural environment of the WRHA, specific threats to important species, ecosystems and ecosystem services, and the community and council response to those threats. Monitoring changes in these indicators over time will be used to assess whether environmental protection and management within the Heritage Area is meeting the requirements of the Act. However, there are a number of limitations in the data that was available for this first monitoring report. These include missing data and/or inadequate length of time to judge whether changes in some indicators are natural variation or an actual trend. Therefore, the results presented in this report should be seen as provisional. One of the most important outcomes of this report is to outline a robust framework for future monitoring and stimulate the collection of ‘missing’ data. ...
