Ulidarra National Park contains moist forest communities, such as rainforest and wet sclerophyll forest, and provides connectivity between the hinterland and plateau habitats of the World Heritage listed Dorrigo National Park, through the mountain ranges of Tuckers Nob in Bindarri National Park, to the coastal habitats of Moonee Beach Nature Reserve and Coffs Coast Regional Park. As a result Ulidarra National Park supports a high diversity of animals. Twenty-two native animal species recorded in or within a kilometre of the park are listed as threatened species.
Ulidarra National Park lies within a broader area which was regularly used by the local Gumbaynggirr people for hunting, the gathering of foods and bush medicines and for ceremonies.
