The Durgău-Valea Sărată area, where the main access to Turda Salt Mine is located, together with Băile Sărate micro-depression, is part of the Natura 2000 Site Ocna Veche Salt Lakes , found in Turda municipality. Within the protected area, on visible surfaces (140 ha), a halophilic vegetation has developed, specific to the areas where there are large deposits of salt.
It represents a wet – salt lakes, salt marshes – or less wet area – grasslands and meadows – resulting from salt exploitation, both on the surface and underground.
Within the area of the reservation vegetation groups of Salicornia halophilic plants developed as well as several species of moss (Meesia longiseta), fen orchid (Liparis loeselii), and plumeless saw-wort (Serratula lycopifolia).
Globally, such areas are relatively few, with a major risk of extinction due to the natural evolution of the environments that host them.
