| Notes on data, analysis and | Mike Griffin provided sketch maps showing the distribution of each species, based on all records available to him and his |
| compilation: | knowledge of habitat preferences. These were synthesised to generate estimated numbers of species per quarter degree |
| | (approx 27 x 27 km). A grid file (at 5km cell size) was created from point data (i.e.centroids of QDS) using a kriging |
| | interpolator. The shapefile was created from the grid file once suitable class intervals were identified. |
| Data quality and organisation |
| Positional Accuracy: | Original data collected at quarter degree square (approx 27 x 27 km) resolution, however much of the data are predicted |
