Relative occupancy of red and grey squirrels when grey squirrels are assumed to initially occupy all viable habitat. The names are of the forests that the model predicts can act as natural strongholds. Note, not all natural strongholds have been named due to overlap or close proximity to existing strongholds, which would enable their location to be determined. The 19 designated strongholds (Scottish Forestry 2020) are outlined in black.
