Bold Park was declared an A-class reserve on 10 August 1998 for its high conservation, landscape and recreation values and vested with the Botanic Gardens and Parks Authority for management. It is one of the largest remaining bushland remnants in the urban area of the Swan Coastal Plain, covering 437 hectares near the coast.

The vision for Bold Park is 'to be identified as a world-class urban wilderness enjoyed, studied and managed with the community'.

 Bold Park has an impressive biodiversity, with over 1000 native and non-native species of flora, fauna and fungi identified. Over 300 different local native plants are found within the park boundaries, including a number of priority and regionally significant species. Despite its proximity to the city, there is an abundance of wildlife including birds, reptiles, amphibians and invertebrates. An array of almost 500 species of macrofungi have also been documented.
