A shrinking desert
In a world that is facing the threat of desertification due to climate change, the Manitoba desert is experiencing a strange phenomenon: it is slowly shrinking as vegetation begins to take over.
According to a study from the late 1990s, the Spirit Sands dunes have shrunk by as much as 10-20 percent over each of the previous four decades due to the encroachment of vegetation.
Experts believe that this process, known as natural succession, is a result of changes in climate and land use in the region.
