 The SPNI also initiated a survey that identified and mapped the area's nature and landscape features; on the basis of this survey, the SPNI in co-operation with the Jewish National Fund (JNF) drew up a conceptual plan for the Sand Dune Park.The great demand for land use in the area of the dunes, the scant awareness of their value, and the fact that there have already been approved building plans for the area have made the establishment of a park a most difficult challenge.Progress in creating the park has been made through a combination of educational and informational activities to heighten appreciation of the area and public campaigns against the existing building plans, along with programmatic activity toward outlining the park.
