ESTABLISHMENT OF NATURAL GRASSLAND SPECIES ON ROADSIDES OF SOUTHEASTERN AUSTRALIA
Establishment and survival of the native grass Danthonia Richardsonii was compared with those of standard grassland mixtures used to revegetate roadsides by two public authorities in southeastern Australia. Seed mixtures were sown in spring 1988 and autumn 1989. Results from monitoring seedling survival, foliage cover and basal cover for the first 12 months are presented. Compared to the introduced grasses, Danthonia plants were smaller and slower growing in the first 2-3 months (spring) or 4-5 months (autumn) after sowing. Despite much lower sowing rates, densities of Danthonia were equivalent to densities of the other seed mixtures by 16 weeks after the spring sowing, but were still lower than the Canberra (CPA) mixture at 28 weeks after autumn sowing. We conclude that, except for a lower seedling growth rate initially, Danthonia richardsonii is a potentially useful native grass for revegetating roadside corridors in southeastern Australia. A complementary research programme on the regeneration biology of another native grass Themeda australis (syn. T triandra) and some colourful native herbs has begun. In the longer term, seed of these species will be included in revegetation mixtures for roadside plantings. For the covering entry of the conference, see IRRD abstract no. 843352.
