Reasons for variable establishment of Jarrah (Eucalyptus marginata D. Don ex Sm.) and Marri (Corymbia calophylla (Lindl). K. D. Hill & L. A. S. Johnson) on restored forest sites after bauxite mining in south‐west Australia are not well understood. To refine restoration outcomes, we compiled tree seedling density establishment data from surveys of 6...

Xanthorrhoea...is in habit one of the most remarkable genera of Terra Australis, and gives a peculiar character to the vegetation of that part of the country where it abounds’ Robert Brown (1814). Grasstrees (arborescent Xanthorrhoea, Dasypogon, Kingia), with their crown of long narrow leaves and blackened leafbase-covered trunk (caudex), are a cha...

There is disparity between the estimated time of origin of the ‘superclade’ Dipterocarpaceae sensu lato, that includes Sarcolaenaceae, Cistaceae, Pakaraimaea, Bixaceae, Cochlospermaceae and Sphaerosepalaceae, as determined by recent molecular phylogenies (100−85 million years ago, Ma) and its strongly tropical, South American-African-Madagascan-SE...

Despite the global implementation of plastic waste reduction policies and bans on single use plastics (SuPs), their effectiveness for protecting marine ecosystems remains unclear. Frequent monitoring could confirm policy effectiveness, but this is difficult due to resourcing and logistic constraints. This study tested a ‘beach litter’ beachcombing...

In a unique study, Luna (Luna, Sci Rep 10:1-10, 2020) examined the viability and germination of 12 hard-seeded Cistaceae in the Mediterranean Basin by alternating a prolonged summer-type temperature (50/20°C at 12 h cycles) treatment with a fire-type heat pulse. A re-analysis of their data shows that the summer treatment applied before the heat pul...

Plants can be categorised by their growth response to temperature, and several studies have demonstrated that more than one thermal type is represented in Australian Mediterranean environments (e.g. Specht et al. 1981) Specht and colleagues (Specht and Dettmann 1995, Specht and Specht 1999) suggest that the overstorey species in Mediterranean Austr...

Abstract Water stress usually arrests growth of even the most deep-rooted species during summer drought in Mediterranean-type climates. However, scant evidence suggests that grasstrees may represent an unusual exception. We used weather data and plant water potential to investigate the relationship between leaf growth and season in the grasstree, X...

To distinguish fire-stimulated growth from the underlying growth patterns imposed by season, we measured leaf production of Xanthorrhoea preissii Endl. (Xanthorrhoeaceae). We compared unburnt with spring- and autumn-burnt sites in forest and woodland habitats. Following fire, X. preissii responded with accelerated leaf production, regardless of sea...

Australian grasstrees are a long-lived group of arborescent, monocotyledonous plants that persist in fire-prone landscapes. Renowned for their capacity to survive fire, and flower soon after, these species have long attracted the attention of biologists. A southwestern Australian species, Xanthorrhoea preissii, has been the subject of several recen...

Alcoa of Australia has mined bauxite for the production of aluminium since 1963 in Western Australia's northern Jarrah ('Eucalyptus marginata') forest. While the company has made significant advances in its rehabilitation methods some plant species still pose a challenge in restoring native Jarrah forest vegetation (Koch 2007). The cycad 'Macrozami...
