In an era of climate emergency and political upheaval, heritage demands radical rethinking. This volume confronts the Enlightenment-rooted dualisms that fragment heritage into opposing categories. By embracing posthumanist concepts like naturecultures and agency, this volume explores entangled human and nonhuman pasts, from the contested Białowieża Forest to ancient sensory environments. Through case studies spanning archaeology, museum studies, and literary analysis, contributors unravel heritage as a dynamic, more-than-human meshwork. This collection is an urgent call to transcend reductive binaries, fostering an ethical, responsive, and sustainable heritage practice attuned to our shared, precarious futures.
