Nullamanna National Park vegetation mapping was undertaken by Dr John T. Hunter in 2008 by contract for the NPWS Northern Tableland Region. Nullamanna NP is a small reserve of under 300 ha that occurs within the North Western Botanical District and the Nandewar Bioregion. The reserve lies closest to Kings Plains National Park.

The vegetation of Nullamanna National Park is described and mapped (scale 1:25 000). Five communities are defined based on classification (Kulczynski association). These five communities were mapped based on ground truthing, air photo interpretation and landform. Much of the reserve is characterised by Callitris endlicheri, Eucalyptus dealbata, Eucalyptus crebra, Eucalyptus caleyi and Eucalyptus moluccana with a shrub layer of Leucopogon muticus, Notelaea microcarpa, Melichrus urceolatus and Leptospermum brevipes with a ground layer of Cymbopogon refractus, Cheilanthes sieberi, Austrodanthonia caespitosa, Aristida ramosa and Panicum effusum.
