Fig. 1: Human pressure compromises structural connectivity of protected areas.

The spatial distribution of the PA estate (blue) littered throughout nonintact (yellow) and intact land (green), as ascertained using the HFP (2013). Intact land was defined as having a HFP < 4 (following Beyer et al.36). We provide six fine-scale examples, starting top left and moving clockwise, Greenland, Finland, Egypt, Papua New Guinea, Democratic Republic of Congo, and Guyana.
