Atascosa Borderlands is a community-based visual storytelling project which combines film photography, recorded oral history interviews, botanical collection, and digital archivization to create a living archive of this 42-mile section of the US-Mexico border. The project developed out of an ecological flora and photographic survey of a remote expanse of the Coronado National Forest in Southern Arizona known as the Atascosa Highlands. An important biological and cultural corridor between Mexico and the United States, the Atascosas take up less than 1% of Arizona's overall landmass, but host around one-quarter of the state’s flora, including species which are found nowhere else in the United States. It was while conducting this research, beginning in 2017 that documentary photographer Luke Swenson and naturalist and writer Jack Dash, began to realize the complex cultural, historical, and ecological significance of this notoriously rugged landscape. Their work examines the region's use as a migratory and smuggling route, recent border wall construction in the area, and ongoing environmental and social disruptions. Exploring the nuanced realities of this part of the Arizona-Sonora Borderlands alongside cattle ranchers, ecologists, humanitarian aid workers, migrants, militia members, coues deer hunters, ex-border patrol agents, and indigenous community members.
