This is a major problem for ditched enclosures in
Alentejo region. In the last few years agricultural fields are being
reconverted and olive trees and vineyards are being planted in extensive areas.
This is done without any previous Archaeological survey and the result is that
a lot of archaeological sites are affected, destroyed or become inaccessible to
research (for instance, for geophysical survey).
This is happening with some ditched enclosures, and
our “google prospection” is documenting it, for some sites identified in images
from 2003 or 2006 are now invisible or almost.
It was this that happened to Perdigões enclosure 16
years ago. There, though, it was possible to interrupt the process after the plowing
and assume the area as an archaeological reserve. But recently, several others do
not have the same fortune.
