The vegetation of the Mount Murchison and Wilga areas, Paroo Darling National Park (latitude 31o00’-32o 40’S and longitude 142o10’-144o25’E) in 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. In the survey 237 vascular plant species including 37 (15.6%) exotic species, from 46 families were recorded. Seventeen vegetation communities were identified and mapped, 15 for Mount Murchison area and 13 for the Wilga area. The most widespread for Mount Murchison being Maireana pyramidata low open shrubland, Flindersia maculosa low open woodland, Muehlenbeckia florulenta open shrubland and Eucalyptus coolabah / Eucalyptus largiflorens open woodland. The most widespread for Wilga being Muehlenbeckia florulenta open shrubland and Eucalyptus coolabah / Eucalyptus largiflorens open woodland. Many of these communities have been impacted by a history of 150 years of pastoral use.
The vegetation of Peery Lake area, Paroo-Darling National Park (32°18’–32°40’S, 142°10’–142°25’E) in 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. 378 species of vascular plants were recorded from this survey from 66 families. Species recorded from previous studies but not noted in the present study have been added to give a total of 424 vascular plant species for the Park including 55 (13%) exotic species. 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. One hundred and fifty years of pastoral use has impacted on many of these communities.
The vegetation of Coonavitra area, Paroo Darling National Park (latitude 31°00’–32° 40’S and longitude 142°10’–144°25’E) in 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. In the survey 261 vascular plants species including 37 (14%) exotic species, from 50 families were recorded. Eighteen vegetation communities were identified and mapped, the most widespread being Casuarina pauper/Alectryon oleifolius low open woodland, Acacia loderi tall open shrubland, Flindersia maculosa low open woodland and Acacia aneura open-shrubland. Of particular significance are the extensive areas of Acacia loderi and Acacia melvillei tall open shrubland and one of the northernmost occurrences of Eucalyptus socialis tall open shrubland. Many of these communities have been impacted by a history of 150 years of pastoral use.
