In this paper, we share insights from our creative practice-based experimentation with ‘feral’ ways of stimulating eco-social change. Drawing on our experiences with three practice-based research projects – Open Forest, Cyano Automaton, and Open Urban Forest – we discuss how feral ways may foster more-than-human co-creation of knowledge and data, and nurture pluralistic making sense-with other-thanhuman creatures. We first explore the concept of feral in supporting the understanding of how creative eco-social inquiries may evolve beyond the bounds of anthropocentrism, in relation with more-than-human experiences. Through our three cases, we illustrate how experimenting with feralness can bring to the fore issues of power, agency, and control in the currently human-centric discourses around data, technology, and sensemaking in eco-social transformation. By sharing our emerging insights regarding feral ways, our aim is to help nurture critical, more-than-human perspectives in creative practice-based inquiries in art and design.
