Photograph something wild. Mother Nature identifies it, reads its rarity from the Red List and its bioindicator value from the science, and the same fixed formula every card uses computes its Hero Rating. Common things can be heroes too.
How the score is built. Identification is AI-assisted and shown with its confidence; anything uncertain is marked "to be confirmed" for a human recorder before it counts. Rarity is anchored to the species' IUCN Red List category, bioindicator value to documented sensitivity. The Hero Rating is computed here by a fixed formula (30% role, 25% bioindicator, 20% rarity, 15% legacy, 10% sensitivity), so every card is consistent. Ratings tell a story; they are not a measurement.
