Global patterns of human–wildlife spatial associations and implications for differentiating conservation strategies

Abstract

AbstractUnderstanding the global patterns of human and wildlife spatial associations is essential for pragmatic conservation implementation, yet analytical foundations and indicator‐based assessments that would further this understanding are lacking. We integrated the global distributions of 30,664 terrestrial vertebrates and human pressures to map human–nature index (HNI) categories that indicate the extent and intensity of human–wildlife interactions. Along the 2 dimensions of biodiversity and human activity, the HNI allowed placement of terrestrial areas worldwide in one of 4 HNI categories: anthropic (human‐dominated areas), wildlife‐dominated (little human influence and rich in wildlife), co‐occurring (substantial presence of humans and wildlife), and harsh‐environment (limited presence of humans and wildlife) areas. The HNI varied considerably among taxonomic groups, and the leading driver of HNI was global climate patterns. Co‐occurring regions were the most prevalent (35.9%), and wildlife‐dominated and anthropic regions encompassed 26.45% and 6.50% of land area, respectively. Our results highlight the necessity for customizing conservation strategies to regions based on human–wildlife spatial associations and the distribution of existing protected area networks. Human activity and biodiversity should be integrated for complementary strategies to support conservation toward ambitious and pragmatic 30×30 goals.
