Table 2. The proportion of species moving northwards in each of the four partitions for plants with decreasing occupancy.
The overall average is calculated as if the four separate partitions were replicates of the same experiment (n = 4).
| Partition | Number of species moving north |
Total number of species |
Proportion moving northward and 95% confidence interval |
|---|---|---|---|
| Scotland | 147 | 382 | 0.38 (0.33–0.43) |
| Northern England | 184 | 263 | 0.70 (0.63–0.76) |
| Wales | 156 | 280 | 0.56 (0.50–0.62) |
| Southern England | 143 | 356 | 0.40 (0.35–0.45) |
| All | 0.53 (0.35–0.64) |
