Fig. 4From: Ecological connectivity in fragmented agricultural landscapes and the importance of scattered trees and small patchesPatch-scale delta integral index of connectivity (IIC) metric modelled: a with the gap crossing layer characterising movement between scattered trees and b without the gap crossing layer. The importance of linkages and patches is denoted by the thickness of the lines and size of the circles respectively. The circles are located at the centroid of each patchBack to article page
