In page Landes (department):

"

During the first part of the 19th century, large parts of the department were covered with poorly drained heathland (French: lande); this is the origin of the department's name. The vegetation covered rich soil and was periodically burned off, leaving excellent pasturage for sheep, which around 1850 are thought to have numbered between 900,000 and 1,000,000 in this area. The sheep were managed by shepherds who moved around on stilts and became proficient at covering long distances in boggy conditions after rain.[1] Most of the sheep departed during the second half of the nineteenth century when systematic development of large pine plantations transformed the landscape and the local economy.[citation needed]
