Abstrakt: Fires, storms, cyclones and human activities impact coastal vine forest communities around Darwin. To restore these communities after such disturbance, information on the fruiting season and seed germination of native species is important for collecting and propagating their seeds. We studied the seasonal occurrence of fruiting and the requirements for seed germination of 19 coastal vine forest species in Darwin's East Point Recreational Reserve. Fruiting and seeding were seasonal, nine species set fruit during the Wet season and 10 species set fruit during the Dry season. Seed fall lagged by two or three months behind fruiting. Thirteen of the species did not have any seed dormancy and five species were treated to break dormancy. With the application of the most effective germination treatment, two species started to germinate within two days, and all except two species commenced germinating within 14 days. Maximum germination of all species had occurred within 30 days. Because dispersal of mature seeds of most species occurs over only one or two months each year, fire impacts prior to dispersal could disrupt seed availability for at least one year.
