This study investigates seed dormancy and germination in the genus Tasmannia. Two Australian species endemic to tropical rainforest, namely T. sp. Mt Bellenden Ker and T. membranea, were used as representatives of the genus. The distribution of T. sp. Mt Bellenden Ker is restricted to tropical montane cloud forests in far-northern Queensland (FNQ). This habitat is highly susceptible to climate change; therefore, studies that contribute to implementing conservation strategies are essential to preserving its unique flora.

Characterising the composition and structure of riparian and floodplain woody vegetation is an important step in making informed water-management decisions. In the large river system of the lower Fitzroy River, Western Australia, vegetation reflects different habitat types, related to fluvial processes. Water managers are encouraged to consider how changes to the flow regime may affect landscape units differentially to help protect riparian and floodplain vegetation across the river and floodplain landscape.

Multiple lines of evidence show centurial-scale changes to habitats and long-term resilience in the threatened Acacia dangarensis at Mount Dangar, New South Wales. Wet–dry phases in climate operating on 200-year cycles, linked to major fire events, work to maintain A. dangarensis within the landscape (above or below ground), and long-term resilience in this species is demonstrated over the past 195 years.

This study developed synthetic-seed methods for Leptospermum polygalifolium and L. scoparium, which are sources of nectar for producing high-value therapeutic honey. Both species proved amenable to propagation via synthetic seed, using a simple formulation of hormone-free, full-strength Murashige and Skoog medium in the encapsulation solution and emergence medium. This method will facilitate mass-production of plants for establishing Leptospermum nectar plantations.
