Factors affecting Dupont´s lark distribution and range regression in Spain
Fig 3
Map of probability of presence of Dupont’s lark in Spain.
The colour range represents the lowest probabilities in yellow and the highest values of probability (0.82) in more intense tones of red. Four main areas are defined by the highest values: two large and continuous areas in the Iberian Mountains and the Ebro Valley, a strongly fragmented area in the North Plateau and an Eastern Corridor, with lower values of probability of presence, connecting the core areas with the southernmost range of the distribution. Finally, several coastal areas show high values of probability, although they are dispersed in small and isolated patches.
