Biodiversity health scores across the Isle of Man, mapped on an H3 hexagonal grid combining 1.49 million species occurrence records, satellite tree cover, and SRTM elevation data.
Open Interactive Ecosystem MapThe full-screen interactive map divides the Isle of Man into 1,947 hexagonal cells using Uber's H3 spatial indexing system at resolution 8. Each hex covers approximately 0.74 km².
Every hex is classified into one of 7 biome types and scored from 0–100 for biodiversity health. Click any hex to see its species breakdown, taxonomic groups, tree cover, and elevation. Select from the “Most Abundant” or “Least Healthy” lists to explore biodiversity hotspots and cold spots.
When AI species illustrations are available, a filmstrip along the bottom of the map displays representative species for the selected hex — click any thumbnail to view the full illustration.
Open the MapDense woodland with high biodiversity
Waterlogged habitats — bogs, curraghs, marshes
Moorland and mountain heath above 200m
Agricultural land with hedgerow networks
Shoreline and intertidal — seabirds, marine life
Towns and gardens — accessible wildlife
Exceptional species richness — conservation priority
Each hexagon is scored on four equally-weighted dimensions, normalised to 0–100:
Biome classification uses a rule-based system: hexes with no land pixels are marked coastal, hexes above 200m with sparse tree cover become upland heath, high tree cover with rich species diversity indicates forest, and so on. The “Biodiversity Hotspot” biome is awarded to hexes in the 90th percentile for species richness regardless of other characteristics.
