This article introduces the concept of maternal ecopsychology, which integrates ecological awareness into the transition to motherhood, or matrescence. It argues that motherhood uniquely positions women to move from an anthropocentric worldview to an ecocentric one, fostering both personal growth and environmental stewardship. This shift often involves ecodistress, where mothers experience psychological distress linked to ecological concerns, which, when supported, can promote resilience and deeper ecological identity. The authors also advocate for nature-based therapeutic interventions to support mothers’ mental health, proposing that such ecotherapeutic practices can address the ecological conflicts that often arise during matrescence.
