Only ten percent of the global terrestrial protected area network is connected via intact land
Land free of direct anthropogenic disturbance is considered essential for achieving biodiversity conservation outcomes but is rapidly eroding. In response, many nations are increasing their protected area estates but little consideration is given to the context of the surrounding landscape. This is despite the fact that connectivity between protected areas is critical in a changing climate and mandated in international protected area targets. By utilizing the latest human pressure assessment, which shows that [~]40% of the terrestrial planet is still intact, and a connectivity method, we found just 9.7% of Earths terrestrial protected network can be considered connected. On average, 11% of each nations protected area estate is connected via intact land. As the global community commits to bolder action on abating biodiversity loss, only an increased focus on landscape-scale habitat retention and restoration efforts will ensure those critical areas safeguarded for conservation outcomes will remain (or become) connected. One Sentence SummaryOnly 9.7% of the global protected area network can be considered connected by intact land.
