What are the ID numbers of the Special Areas of Conservation?
The Identification (ID) numbers of Special Area of Conservation are their SAC (ZEC in Spanish). The ID numbers of each Special Area of Conservation are available in the sites’ listings created in Wikipedia. Some natural sites do not have an ID, and they do not participate in this contest because without that information the pictures cannot be read by the programs that are in charge of their classification. Only the images uploaded with their associated ID number will be able to take part in the contest.
