Pond Dwelling Beaver suitability was classified in a GIS by:
Selecting waterbodies greater than 10000m2 (assumed
this is the minimum size at which ponds are deep
enough to avoid complete freezing over winter).
Selecting suitably-sized waterbodies with both an inflow
and an outflow.
Calculate the % cover of deciduous tree/shrub cover
within a 100m buffer surrounding suitable waterbodies. Suitable waterbodies were ranked as follows (probability of beaver occurrence): <10% cover (none), 10-30% cover (low), 30-50% cover (moderate), >50% cover (high).
