The nucleus of the present Berowra Valley National Park is the Elouera Bushland Natural Park,
which was reserved in 1964 by the then Minister for Lands ‘for public recreation and promotion of the study and preservation of native flora and fauna’. For twenty-four years this Park was managed by a group of honorary trustees appointed by the Minister for Lands. The
Elouera Bushland Natural Park Trust was gazetted on 6th November 1964
The Park covered an area of some 640 ha of bushland in the southern portion of Berowra Valley. The main watercourse within the Park was the upper reach of Berowra Creek,
known locally as Fishponds Creek. The Park lay in the heart of Hornsby Shire, adjacent to Hornsby, Westleigh, Thornleigh, Pennant Hills and Dural.
During the 1980s the Trust developed the first formal Management Plan for the Park. It also helped to develop the Benowie Walking Track and initiated moves to control
weeds, build better walking tracks and to extend the park. boundaries. The Trust did not have fixed terms, but was augmented as people retired or died. The Trust was dissolved in 1987 when the Park was enlarged to become the Berowra Valley Park:
On the western boundary the urban areas continued to expand. Covering more than 3800 ha of bushland within the Hornsby Shire, and bounded by both urban and rural lands, it
extends along Berowra, Calna, Tunks and Pyes Creeks between Pennant Hills and Berowra, and links with Marramarra National Park and Muogamarra Nature Reserve. Berowra Valley
Regional Park was gazetted on 27 March 1998.
It was managed until 30 June 2004 by the Berowra Valley Regional Park Trust
on behalf of the Minister for the Environment and Hornsby Shire Council. The Minister’s interests are represented by the National Parks and Wildlife Service.
In 2006, Council reduced its involvement in the management of Berowra Valley Regional Park.
Berowra Valley National Park
was created on 24 August 2012 under the management structure of the NSW Government. To deal with some land title matters, several small areas of land amounting to less than 10ha, remain under the previous management structure as
Berowra Valley Regional Park.
