Identification keys are designed to help you work out what type of wildlife you have seen, by answering a series of questions about the species you are looking at. The identification keys on iSpot have been designed using a novel approach based on Bayesian statistics, and may be different from other keys that you have encountered.
Simply describe your specimen by answering as many questions as you can, and iSpot will sort through the list of species it knows about and suggest which is most likely. When a species is starred, you have a good match - check the description to confirm your identification, and follow the links for more information. Unlike a traditional branching (‘dichotomous’) key, you don't have to answer questions in a fixed order. Our keys use probabilities: simply, the more evidence you can provide, the more definite your identification will be.

- Lichens on trees
- Crustose lichens on trees
- Foliose lichens on trees
- Fruticose lichens on trees
- Trees (species in OPAL surveys)
