Look up a plant's recorded climate range or a place's climate on its own, or add the evidence and charts to an assessment.
Adds the per-source breakdown and the climate comparison charts.
Each measure is scored separately, then combined into an overall result. Warmth, winter cold and drought stress are ticked to start with: together they give the broadest view of climate risk.
Temperature
Average temperature across the whole year — the broadest measure of warmth.
How cold winters get, which sets the hardiness limit for many plants.
Moisture
Total rainfall over a year.
Aridity
How much more water plants could use than the climate supplies — drought stress.
Ratio of water supply to demand, so wetness and dryness on one scale.
How strongly the air pulls moisture from leaves — drying wind and evaporative stress.
Where the records of this plant's climate range come from. Wild records show what a plant tolerates unaided; cultivated records show what it tolerates with care.
Natural and naturalised
Occurrences away from towns — closest to where the plant grows unaided.
Mixed
Occurrences in built-up areas, which mixes wild and planted records.
Modelled niche breadth for plants of this type, used where records are sparse.
Cultivated
Living collections, so evidence of what can be grown with care.
Botanic garden holdings recorded in PlantSearch.
Street, park and garden plantings.
Baselines describe the past and present; SSP scenarios are projections under different global emissions paths.
Baseline
Conditions before industrialisation and urban heat.
The reference period most climate products are built on.
Today’s climate, including urban heat.
Future
Emissions cut quickly.
Emissions stay near today’s levels, then fall.
Emissions keep rising.
