The overall speed of movement of the modelled species from source to target in this landscape is 0.2842. The lower the speed, the longer the time it would take for the first colonisation of the target. The relationship between Condatis' speed and the rate of movement in population simulations is very significant, but not exact or linear (Hodgson et al., 2012). If speed is <<1 it probably indicates that many generations would be needed for the species to reach the target. If the speed is >>1 it may indicate that there are many alternative routes which all have a possibility of leading to the first successful target colonisation.
Flow Map
Fig. 1: The pattern of flow of individuals from source to target across the landscape. Flow through each cell is represented by the colour ramp, (note log scale). The source and target are labelled using MAGENTA █ and CYAN █ respectively. Cells that do not contain habitat are grey.
Progress of Movement
Fig. 2: The progress of movement from source to target is illustrated by the colour ramp. Bands of similar colour lie at a similar effective distance between the source and the target, e.g. a value of 50%, as demonstrated in the legend, represents the cells the species is expected to reach within half of the total 'travel' time. The source and target are labelled using MAGENTA █ and CYAN █ respectively.
Fig. 3: Shows the links with the highest power. Power can be thought of as the "strain" placed on that link relative to the rest of the circuit. This plot shows the top links as requested. Consult pdwoodaroundNforest1kmFlow_bottlenecks.csv or view the shapefile pdwoodaroundNforest1kmFlow_bottlenecks.shp for actual power values. The habitat layer is in green for reference.
