The area of the mine known as Korea by the locals is interesting mostly for the fact that it was flooded with groundwater after the abandonment of its black coal extraction.
The area that was once upon a time a dump of mine tailings was in a few decades overgrown by reeds and other vegetation, so that only some »water windows« can still be seen here and there. In the west, the area is surrounded by the second evaporation basins, while in the east it borders on fields, regional road and the village of Sečovlje. Part of this mining area has been converted into a place of habitat for the European pond terrapin. The area is also used by some breeding bird species and plays an important role in the winter period when 300 or more ducks dwell here. It is also significant owing to the numerous dragonfly and damselfly species that can be found here.
