Reconnect with the natural environment at the Biodiversity Garden, Dubbo Regional Botanic Garden.

It is a safe wilderness; a place for adventure! Young children love to follow the winding trails through grassy white box woodlands, past wetlands and into the forest. 

It is an educational resource; an outdoor classroom. The Biodiversity Garden displays the major ecosystems that thrived in the Dubbo region before European settlement. Schools regularly visit the garden to study the plants and their habitats.

Interpretative signage near the Kurrajong tree in the north-west corner of the garden provides an informative bio-geographical overview of the region.

The diversity of the botanical collection and the deliberate policy of allowing the garden to develop a natural life cycle add to the “wild” and unpredictable experience offered by the Biodiversity Garden.

The Hardenbergia violacea is currently providing a beautiful and abundant display of delicate purple flowers and at least three species of wattle are also in bloom.

Sharp eyes may spot bright orange fungi growing on fallen tree branches which have been left to provide habitat and refuge for native animals.

Amongst the leaf litter, earthstars are popping up. These small, strange and delightful fungi belong to the genus Geastrum and look like puff balls on star-like bases. 

Fungi performs two essential roles in the Biodiveristy Garden. Firstly, it recycles dead material into a form which can be reused by the plants and secondly, some species form mycorrhizal associations with the plants. Mycorrhizal associations involve an interaction between fungi and the root system of the plant.  The association usually results in an exchange of nutrients beneficial to both organisms. However, some plants such as Australian orchids “harvest” fungi to obtain the nutrients they require.  Mycorrhizal associations are essential to the healthy growth of roughly 80-90% of all plants.

Come to the “wild” side of the Dubbo Regional Botanic Garden, look closely and be ready for a pleasant surprise.
