Hierarchical bioclimate zonation to reference climate change across scales and its implications for nature conservation planning

- Recent/future changes in bioclimate show loss of Oroarctic/Boreal zones.
- Recent/future changes in bioclimate show expansion of Temperate zone.
- Changes in zonation are also marked by uphill shifts in class boundaries.
- Montane heath is priority habitat at highest risk of loss due to zone changes.
- Combined use of heuristics and data collection can further enhance zonation.
