Introduction

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.

Advantages

  • Simple and easy to interpret
  • Presence only model, no absence data needed

Limitations

  • Does not use environmental variables to predict species occurrence

Assumptions

N/A

Requires absence data

No

Configuration options

BCCVL uses the ‘dismo’ package. Currently there are no configuration options for this algorithm in the BCCVL.
