The stabilization of shores of 4 islands will be the next stage of works on the gravel pits located in the Lower Skawa Valley. The planned reinforcements will allow for islands preservation and protection of bird breeding habitats.
In March this year, the Regional Directorate for Environmental Protection in Krakow signed a contract for the preparation of design documentation obtaining the necessary permits and decisions. Works aimed at securing the shores of the islands will be performed in the autumn and winter period.
The washout of shores causes a serious threat to bird colonies nesting on the islands. The islands in the gravel pits were made of the excavated material of the no longer existing sand mines and were never strengthened. As a result of waving water, the shores of the islands are subjected to erosion. This results in a decrease in the area of the island, which reduces the area of breeding habitats of birds.
The construction of island protections will contribute to the improvement of the habitats of night herons and river terns, which is one of the main goals of the LIFE.VISTULA.PL project.
