The vegetation of Peery National Park in Far North Western New South Wales was assessed using intensive quadrat sampling and mapped using extensive ground truthing and interpretation of aerial photograph and Landsat Thematic Mapper satellite images. Three hundred and sixty two species of vascular plants were recorded from this survey from 66 families, including 51 (14%) exotic species. Species recorded from previous studies but not noted in the present study have been added to give a total of 422 vascular plant species for the Park. Twenty vegetation communities were identified and mapped, the most widespread being Acacia aneura tall shrubland/tall open-shrubland, Eremophila/Dodonaea/Acacia open shrubland and Maireana pyramidata low open shrubland. The Park was created in September 2000 from three pastoral stations: Peery, Mandalay and Arrow Bar. An intensive vegetation survey was undertaken in October 2001. VIS_ID 3968
