Earlier this spring, I traveled to central Arizona to investigate the illegal poaching of saguaro cacti for Red Bull's Terra Mater magazine. The National Park Service recently began tagging saguaro cacti in order to prevent theft - which is primarily tied to housing development in the region. However, saguaro cacti are often harvested for landscaping beyond the region bound for California or even China.
The state requires that transplanted cacti be tagged. The only exception to this is if a private land owner is merely relocating one within their own property.
We weren't able to connect with any subjects who illegally harvested. To strengthen the story visually, I looked at how saguaros were represented in the landscape, from wild plants on national forest land and in Saguaro National Park to residential applications in old trailer parks and million dollar homes as well as roadside plantings by the Arizona Department of Transportation.
