Volcanic Soils Are Not Invulnerable: Technical Priorities after the First Detection of Phylloxera in the Canary Islands

Composite image made from data from ISRIC SoilGrids showing Lanzarote versus Tenerife. These are point-based profile means rather than island-wide spatial averages and are simple averages across the six standard depth layers (0 to 5, 5 to 15, 15 to 30, 30 to 60, 60 to 100, 100 to 200 cm). As modeled predictions (250-m resolution), they may differ from local ground surveys. Profile values are shown on the left panels (units converted from g/kg to %). Currently, no general maps based on ground surveys exist beyond specific site data for the islands.
