Vegetation references

1. Rodney Ecological District

The Rodney data for the vegetation layer was constructed from the original 1982-4 field survey maps and cards. The polygons were delineated from 1998 aerial photographs and attributes added from survey maps, cards and the PNA and SNA reports.
They were then reclassified into the regional classes.

2. Awhitu/ Manukau Ecological Districts

The Manukau and Awhitu ecological districts were initially vegetation mapped by Landcare Research in 2002. They used monochromatic SPOT satellite imagery to delineate polygons. They were added to by ARC using aerial photography as a base, in 2003.

3. Waitakere Ecological District

The Waitakere vegetation map was scanned from the PNA report and then digitised. Attributes were added from the PNA map then they were reclassified into the regional vegetation classes.

4. Inner Gulf Islands Ecological District

Waiheke Is.– Auckland City Council. Most of the Waiheke Island vegetation was mapped by aerial photo interpretation and supplied by Auckland City as a GIS file in time for the project. The vegetation attribute data was supplied by Dr A. Julian. Areas uncompleted were taken from a report by:

Fitzgibbon, T.D. and D.C. Slaven. Sites of ecological significance: Waiheke Island (1988) [Wellington, N.Z.] : New Zealand Dept. of Conservation. Northern Region.

Additional areas not covered by these two sources were classified from Land Cover Database 2. Landcare Research.2002.

Kawau Is. Vegetation classes were drawn from a paper by Mitchell and Park 1983.

Ponui Is., The Noises, Browns Islands. Were classified from aerial photography and DoC in house knowledge.

5. Hunua Ecological District.

The Hunua range vegetation map was constructed from GIS polygons contributed by Wildland Consultants. Attribute data from the written report was added to the polygons and they were then reclassified in regional classes. Any areas not covered were mapped from the PNA report.

Site records for the Manukau City Council part of the Hunua ecological district were provided by ARC.

6. Kaipara/Otamatea Ecological Districts.

The digital vegetation data for these ecological districts was supplied by Alison Davis as GIS polygons and database tables. These were joined by ARC and vegetation types then reclassified into regional classes.

7. Little Barrier Island Ecological District.

The Little Barrier vegetation information was digitised from the report map and attributes reclassified to fit regional classes.

LITTLE BARRIER ISLAND (Hauturu) 2nd Ed, (incl. maps), DSIR Bull 137, 1961.

8. Great Barrier Island Ecological District.

Was scanned and digitised by Landcare Research. This map was used for the LINZ Land Inventory NZMS 290 vegetation map series 1982. The base information came from R.O. Gardner, E.K. Cameron. 1980. Vegetation types were then reclassified into regional classes.

9. Rangitoto Ecological District.

The vegetation classification for Rangitoto was based on aerial photo interpretation and geological data.

10. Hauraki, Hapuakohe and Meremere Ecological Districts

Vegetation data was provided by Environment Waikato from their Key Ecological Sites GIS layer 2003.

11. Tamaki

The vegetation attributes for the Waitakere part of Tamaki ED were provided by ARC and WCC as a spreadsheet and digital polygons. It is not recorded as to how the polygons were derived.
