Chapter 6 ECOLOGICAL FIELD SURVEY RESULTS - MAPPING ACCURACY

6.1 MAPPING ACCURACY
   
 
6.1.18 Modified Watercourse
   

The majority of the surveyed sites were mapped with 100% accuracy with only a few sites mis-identified and should be re-classified as Natural Watercourse (Table 6.1o).

6.1.19 Artificial Rocky/Hard Shoreline
   
The habitat was mapped with a high degree of accuracy and the sites surveyed were found to be correctly identified. No re-categorisation was required.

   
6.1.20 Golf Course/Urban Park
   
The habitats selected for field surveys were mapped correctly apart from small areas which were discovered to be residential areas or buildings which were consequently re-classified as Other (Table 6.1p).
