On the afternoon of August 22, 2023, the Tucson Mountain District of Saguaro National Park experienced a blowdown event that knocked over or damaged a large amount saguaros and other vegetation.
What is a blowdown?
Blowdown refers to windthrow and windsnap. Windthrow is a naturally occurring event, and it is common in areas habitating plants with large canopies, or sails, such a multiple-armed saguaro. Windthrow is when the entire plant, including its root structure, is uprooted by the wind. Windsnap is when the plant experiences breakage or is snapped along its trunk.
What does this mean for our saguaros?
The park is continuing to evaluate and execute research on this event in order for park biologists to learn more about this phenomenon and its effects on our ecosystem.
