Prepared for Environment Bay of Plenty. Contract Report No. 1116 1. INTRODUCTION Environment Bay of Plenty commissioned Wildlands Consultants Ltd to undertake mapping of significant natural areas (SNA) in the Opotiki District in the Bay of Plenty Region. This project involved mapping the 2003 extent of significant natural areas based on hard copy maps presented in a 1999 report (Wildland Consultants Ltd 1999). Significant natural areas mapped in the 1999 report included legally protected and unprotected areas. In the current project site boundaries were digitised at a scale of 1:5,000 based on the extent of natural areas visible in 2003 digital aerial photographs. 2. OBJECTIVES The project objective is to map at 1:5000 the 2003 extent of each significant natural area (SNA) identified in the Opotiki Natural Heritage Report (Wildland Consultants Ltd 1999). 3. METHODS All sites in the 1999 SNA report (Wildland Consultants Ltd 1999) were mapped using the 2003 RDAM orthophotos as the mapping base. Each site was mapped on screen at 1:5,000 with reference to extent of the site as mapped on the 1:50,000 topographic maps and sketch maps (scale 1:20,000-1:50,000) presented in the 1999 report. Clearings that could be identified on the digital aerial photographs were excluded from sites. Main roads were also excluded from unprotected sites. Minor boundary changes were made to many of the sites to exclude small areas of pines, pasture, or dwellings, or to include indigenous vegetation. For a few sites, major areas were excluded for one of several reasons e.g. newly established pine plantations; clearance of indigenous vegetation. Any sizeable areas of exotic vegetation (e.g. clearings, plantations) that could be discerned from the digital aerial photographs were excluded from unprotected sites. The Opotiki District administrative boundary was changed in 2004 and 17 sites, and parts of a further three sites, identified in the 1999 report now lie in the Whakatane District. These sites were mapped as part of the current project and are identified in the comments field in the attribute table (see Appendix 1). Boundaries of protected sites were not adjusted. In a few instances the position of the protected areas digital polygon were shifted slightly to fit the position of natural features visible on the aerial photographs, e.g. when straight line boundaries were offset to one side of the actual physical differentiation of vegetation cover. Details about each site were captured in the attribute table. There were 15 fields in the attribute table, and these are listed and defined in Table 1. 1 Contract Report No. 1116 Table 1: Attribute Definition DATE Date of digital mapping (for future reference) NAME Name (most appropriate name if site has had different names in the past) SITE_NO. Unique identifier (Site No.). (This would be a new number so each site throughout the region would have a unique number.) SNA_UNPROT SNA – unprotected (state type and site number in report) UNPSNA_REF Source (report) SNA_PROT SNA – protected (state type and site number in report) PROSNA_REF Source RAP_NO RAP No. RAP_REF Source ED_1_50000 Ecological district 03_HA Area (ha) DIG_SCALE Digitised scale, e.g. 1:5,000 BASE_MAP Base map FIELD_CHK Field check needed CHNG_XTNT Extent (broad comment on any change in extent since reference document completed) COMMENTS Other relevant information 4. OUTPUTS One hundred and seventy-seven sites were mapped. These are listed in Appendix 1 along with the completed attribute table. Sites are mapped at c.1:600,000 in Figure 1. Most or all unprotected sites would require field checking to confirm site boundaries. Shadows on the digital aerial mosaic make it difficult to determine the boundaries in some places, particularly adjacent to pine plantations. Arc shape files were provided to Environment BOP along with the metadata (Appendix 2). The shape file name is Opotiki_District_SNA’s_1999_based_on_2003_RDAM. The metadata is presented in Appendix 1 and was also provided to Environment BOP. REFERENCES Wildland Consultants Ltd 1999: Natural Heritage of Opotiki District.
