Northern Beaches Council will nominate the Manly Warringah War Memorial State Park for State Heritage status, recognising its environmental, Aboriginal cultural, and historical significance.
Council last night agreed to submit an application to the Heritage Council of NSW for consideration.
Mayor Michael Regan said the Park meets the criteria for State listing.
"The heritage values of Manly Warringah War Memorial State Park have been recognised for a century. The Park is highly valued by the local community for its scenic beauty and as a recreation venue, conservation area and Aboriginal cultural site.
"It also includes the historic dam structure and significant ecological communities and populations of rare and endangered flora and fauna.
"State Listing is very important, because it recognises the State Park as a very significant place, and safeguards the environmental, economic and cultural benefits of this fantastic area for present and future generations."
The Park is approximately 377 hectares in size, with areas of remnant bushland, open water and modified landscape (including a golf course and picnic areas).
The Park is Crown land and Council is the Crown Land Manager.
