Existing vegetation mapping projects within the region were reviewed and prioritised according to their resolution and correlation to vegetation recorded within the study area (Table 3.). The review prioritised the more detailed local government vegetation mapping and mapping of conservation reserves over the broadscale vegetation mapping within the region. In this way, the more detailed information and mapping was captured. The local, detailed vegetation mapping projects focussed either on LGAs or on conservation reserves and as such, there were few overlaps in these projects.
In addition to determining the priority of vegetation mapping projects during the consolidation of mapping, this prioritisation was used to assign existing vegetation community profiles to the vegetation recorded during the field investigation. Based on this prioritisation, vegetation communities identified in the field were firstly aligned to the Cessnock-Kurri region vegetation community profiles (Bell & Driscoll 2007) if possible. However, if the vegetation community did not correlate to the Cessnock-Kurri region vegetation profiles, the community was then aligned to the next highest priority mapping project (as outlined in Table 3.). The highest priority mapping projects provide localised vegetation mapping with detailed vegetation profiles of vegetation communities that are often locally restricted. As such, following the prioritisation process, the field identified vegetation communities often did not match these profiles well and were better aligned to the more broadscale LHCCREMS mapping.
Vegetation Survey, Classification and Mapping Lower Hunter and Central Coast Region (LHCCREMS)
Lower Hunter and Central Coast Regional Environmental Management Strategy (2003)
The vegetation mapping is broadscale and was used next in the areas outside aforementioned mapping projects.
Greater Hunter Native Vegetation Mapping (GHM)
Sivertsen et al. (2011)
Based on field surveys within the Cessnock LGA, this vegetation mapping was found to be less accurate and detailed than the above mapping projects. This vegetation mapping project was used only where the aforementioned projects do not occur.
The vegetation mapping was the lowest priority as the vegetation mapping was of similar detail to broadscale mapping projects such as LHCCREMS but lacked the detail and refinement in vegetation profiles.
