This article examines ecological practices at the Palestine Museum of Natural History in Bethlehem, West Bank. Through an analysis of the museum's botanical gardens, the article explores what it calls ‘biodiverse futures’ as a spatio‐temporal alternative to the ecological domination of settler colonialism in Israel/Palestine. While much scholarship has focused on the environmental imaginaries that have informed colonial conquest in Palestine, this paper draws attention to the ways in which these relationships extend into constructions of the future. Combining the literature on environmental violence with the literature on futurity and decolonisation, this article develops an approach that foregrounds the relevance of ‘ecological temporalities’ in examining alternatives to settler futures in Israel/Palestine. To date, only a limited number of contributions have examined environmentalism as a powerful discursive tool for constructing the future. The case of the museum gardens highlights three interrelated aspects of the production of ecological counter‐futures: futures as knowledge, futures as (bio)diversity, and futures as survival. Drawing on ethnographic material and interviews with museum staff and volunteers, this paper contributes to the study of the temporalities of environmental violence and ecological resistance in Israel/Palestine.
