Circles is a geographical model that uses the location of known occurrences and predicts that a species can be present within a circle with a given radius around these occurrence points. This model does not use the input of environmental variables to predict the distribution of a species.
- Simple and easy to interpret
- Presence only model, no absence data needed
Does not use environmental variables to predict species occurrence
Requires absence data
BCCVL uses the ‘dismo’ package. Currently there are no configuration options for this algorithm in the BCCVL.
