Human–Wildlife Conflict Is Not a Myth
Integrative Conservation, Volume 5, Issue 3, Page 250-254, September 2026.ABSTRACT Despite well‐established critiques of the term, human–wildlife conflict remains a valid way to refer to certain types of harmful interactions between people and wild animals. Efforts to diversify human–wildlife interaction terminology beyond the conflict paradigm were partly catalyzed by an influential article in Conservation Letters titled ...
