Vransko Jezero holds the status of a special ornithological reserve due to its exceptional biodiversity, particularly the wetland birds that inhabit the area or stop here during migration. The landscape has been shaped by a combination of natural processes and long-term human influence, visible in the traditional agriculture, fishing, and dry-stone walls that surround it.

The park offers numerous walking and cycling trails, bird-watching hides, and educational resources that help visitors understand the importance of preserving wetland habitats. Beyond its natural value, the area also holds cultural and historical significance, having served as a vital resource for local communities for centuries.

Today, Vransko Jezero functions as a balance between nature conservation and sustainable land use, making it one of the key natural sites in Croatia.
