Vransko jezero i Jasen‎, Protected ecological site near Zadar and Šibenik, Croatia.

Lake Vrana and its surroundings form a mosaic of water, wetland, and meadow across two counties with high ecological value. The area provides habitat for many plant and animal species adapted to these wet environments.

The site was declared a Site of Community Importance in July 2013 under the EU Habitats Directive, protecting one plant and six animal species. It covers 5,912.98 ha, entirely on land, and is nearly identical to the Vransko jezero nature park; the bird protection area of the same name has the same boundaries.

The site overlaps almost entirely with Vransko jezero Nature Park, and the same area is also a European bird protection area of identical extent. It borders the Ravni kotari habitat and bird area to the northeast. The Illyrian iris (Iris illyrica) grows in the wet meadows along the lake shore.

Visitors can access the area through several entry points in surrounding towns, with spring and fall offering the best wildlife viewing as birds migrate through. Comfortable shoes and binoculars help when exploring and watching for animals.

The site was declared a Site of Community Importance in July 2013 to protect one plant and six animal species. Among them are the freshwater mussel Anisus vorticulus, the dragonfly Lindenia tetraphylla and the fish Knipowitschia panizzae. The Illyrian iris (Iris illyrica) grows in the wet meadows around the lake.
