The name Strandja will be registered as a trademark and used for ecologically clean products, produced in the region, like honey and yoghurt.

The trademark would be registered by the Bulgarian foundation Biodiversity, Dnevnik daily said.

Before the registration however, a competition for the design of the logo would be announced. Initially the logo would be used for tourist destinations as a quality sign. Later it was intended to become a trademark.

Foundation Biodiversity said it would accept suggestions for the logo until January 24 2008. The winner would be announced on February 15.
