[3] Its Statement of Significance there reads as follows: 'This nature reserve constitutes a highly important remnant of regionally representative open forest in the agricultural district of the south-west slopes, dominated by Callitris endlicheri and a variety of eucalypts.

Moreover, it represents almost a sole habitat isolate for many species which can be regarded as regionally uncommon due to the extent of clearing, and for irruptive/migratory nectarivorous and insectivorous passerines.

Included within Ulandra Nature Reserve is a relatively undisturbed catchment (feeding Merrybundinah Creek); such a phenomenon is a rarity within an agriculturally transformed landscape of this type.

The terrain is hilly with rough rocky ridges, several steep sided gullies and a catchment which feeds into Merrybundindah Creek.

[5] The reserve shows signs of damage due to previous pastoral clearing and stock water dam construction, as well as continued predation and competition from introduced animals, especially pigs.

[3] Note that, being a nature reserve, members of the public can only enter it if they have permission to do so from the NSW National Parks and Wildlife Service.
