What are dune blowouts?

Dune blowouts are depressions or gaps that form in sand dunes due to the erosion caused by wind. They typically occur in areas where vegetation is sparse, allowing the wind to more easily remove sand from the dune surface. Blowouts can expand over time, leading to significant changes in the landscape and potentially impacting local ecosystems. They are often associated with disturbances such as foot traffic, grazing, or severe weather events.
