The Atascosa Highlands are an area of unmatched biological and cultural diversity, located along a rugged stretch of the US-Mexico border. Over the last three years, ecologist Jack Dash and photographer Luke Swenson have been pursuing an intensive study of the area, designated by the Coronado National Forest Service as the Tumacacori Ecosystem Management Area. Their visual storytelling project, An Annotated Flora of the Atascosa Highlands documents the environmental, political, and cultural forces shaping this unique landscape. Combining social ecology, documentary photography and oral history interviews, their work confronts the diverse, and oftentimes competing perspectives of the region. Join us via Zoom for a live presentation of their work to explore how historical land use and border wall construction along the US-Mexico border is impacting the social ecology of the Atascosa Highlands. This event will be followed by a Q&A with Jack and Luke.
