The Challenge

Our urban forests were planted for a climate that no longer exists

Hotter, drier summers, milder winters, and more frequent extreme weather events are already testing the resilience of urban trees across the UK. Research by Martin & Hirons (2025) found that a staggering 73% of London's publicly owned trees may struggle to thrive or survive by 2090 under projected climate scenarios.

The Kew Reach Climate Resilient Tree Tool translates the latest peer-reviewed research into actionable guidance, helping you select species that will not just survive, but thrive in tomorrow's climate.

Climate vulnerability gradient. As conditions shift from adequate moisture (left) to increasing aridity (right), many familiar species show canopy dieback and decline.

How It Works

A four-layer assessment framework

Climate Modelling

We project future climate conditions for your location using CMIP6 data and the Climatic Moisture Index (CMI).

Species Distribution

Global occurrence data from GBIF maps each species' climatic niche against your site's projected conditions.

Drought Tolerance

Physiological traits like turgor loss point (ΨP0) quantify each species' ability to withstand water stress.

Composite Suitability

A composite score combining climate suitability, drought tolerance, ecosystem services, and biosecurity risk.

Research Foundation

Built on world-leading science

This tool operationalises the integrated assessment framework developed by Kevin Martin, Henrik Sjöman, Andrew Hirons, and their collaborators. It combines Species Distribution Modelling with physiological trait analysis to produce the most comprehensive climate resilience assessment available for urban trees.
