Abstract Extensive areas of tropical Australia are degraded through activities associated with agriculture and grazing, and, to a lesser extent, mining. Rehabilitation of the degraded land is generally limited by low rainfall, unfavourable soil physical conditions and often by salinity. An accession of the grass, Urochloa mosambicensis, and some potential legumes were selected from the collections of the Australian Tropical Forages Genetic Resource Centre (ATFGRC) for evaluation for revegetating land disturbed by open-cut coal mining. While the existing ATFGRC collection provides a valuable source, there are opportunities for expanding the collection, including both exotic and native species, as a resource for future rehabilitation research. It is suggested that Atriplex may be more suitable than pasture species for revegetating very saline and dry areas, and Bothriochloa and Dichanthium spp. may be suitable for clay soils with low rainfall. Plant species which have colonised the harsh mine site environments of central Queensland (Atriplex muelleri, Salsola kali and Enchylaena tomentosa) accumulated high levels of betaines in leaves, suggesting that this is an adaptive character. Research opportunities exist to select more tolerant plant species by utilising this betaine-accumulating character. Betaine concentration of seed could be useful potentially in initial screening for stress-tolerant species. Selected accessions could then be screened for capacity to accumulate betaines during growth, thus further reducing the number of potential accessions to be field tested.
