Core Viewpoint - The Minnesota Zoo, John Ball Zoo, and Assiniboine Park Conservancy have been awarded the 2025 North American Conservation Award by the Association of Zoos and Aquariums (AZA) for their collaborative efforts in the recovery of the critically endangered Poweshiek skipperling butterfly [1][10]. Group 1: Conservation Efforts - The Poweshiek skipperling has seen a dramatic decline in population, disappearing from most of its historical range due to habitat loss, with the last sighting in Minnesota occurring in 2007 [2][6]. - The collaborative efforts of the Minnesota Zoo, John Ball Zoo, and Assiniboine Park Conservancy have led to the development of breeding protocols, resulting in the release of thousands of butterflies to stabilize and grow the remaining populations [3][7]. - The U.S. population of the Poweshiek skipperling is now believed to be derived from just 18 females that were in zoo care at the start of the breeding program [3][6]. Group 2: Achievements and Recognition - The conservation biologists from the Minnesota Zoo have been recognized as 2024 Recovery Champions by the U.S. Fish and Wildlife Service for their leadership in these efforts [5]. - The AZA award highlights the importance of sustained, collaborative conservation efforts and the role of accredited zoos in species recovery [8][10]. - Measurable progress has been observed in 2024 and 2025, including verified persistence at reintroduction sites and a significant increase in wild sightings of the Poweshiek skipperling [9]. Group 3: Research and Collaboration - Cutting-edge research has been conducted, including a unique wing-marking technique for tracking, whole genome sequencing, and studies on threats like pesticide exposure and climate change [7]. - The Poweshiek Skipperling International Partnership has been established to align various government, academic, and community partners across borders for effective conservation [7].
