Plant of the Week Nothofagus moorei – Antarctic Beech In Australia, we take it for granted that most of our trees are either Eucalypts or Acacias (Wattles). However, eastern Australia also has magnificent Antarctic Beech forests, relics of ancient times. Nothofagus was originally included in the family Fagaceae (Beech family) of the Nothofagus moorei forest in Werrikimbe National Park. northern hemisphere Photo: Alison Downing but recent molecular studies have shown that the southern Beech trees were sufficiently different from those of the northern hemisphere to justify moving Nothofagus to its own family, the Nothofagaceae. Nothofagus forests can be found in New Zealand, New Caledonia, New Guinea, Argentina and Chile, suggesting a Gondwanan origin in the Triassic, about 180 – 200 million years ago. Fossils of Nothofagus have also been found in Antarctica. In Tasmania, there are two species of Nothofagus, the deciduous endemic N. gunnii and the evergreen N. cunninghamii, a species which also occurs in Victoria. Australia also has a third species, N. moorei which grows in cool temperate forests of the northern tablelands of New South Wales, from Barrington Tops to the Lamington Plateau of south-eastern Queensland. The finest stands of N. moorei are considered to be those of Werrikimbe National Park in the high country to the west of Port Macquarie1 and they are richly adorned with epiphytic orchids, ferns, fungi, mosses, liverworts and lichens. These are currently the centre of a range of studies by forest ecologist Dr Ross Peacock, a senior research fellow at Macquarie University. 1New South Wales Rainforests - The Nomination for the World Heritage List.

To test its monophyly, we used a three-locus data set including most monocot orders, and to infer its exact phylogenetic position, we used a five-locus extended data set. We corroborated these findings using an independent plas- tome dataset.

Abstract F. Drake, J.R. Molina, and M.Á. Herrera. 2012. An ecophysiographic approach for Araucaria araucana regeneration management. Cien. Inv. Agr. 39(1): 159-176. Chilean temperate forests are dominated by Nothofagus and Araucaria araucana species. Despite A. araucana not being at imminent risk of extinction, its cultural value and the associated environmental services and landscape goods have an important role for the conservation of this native forest. In some areas, the future conservation of A. araucana is a cause of great concern given its management prohibition and regeneration limitation due to slow growth, canopy tree competition and dense understory. The above characteristics make this species most susceptible to some disturbances, such as livestock, wildlife and human pressures. Therefore, sustainable management of A. araucana forests requires the assessment of its regeneration condition. The objective of this research was to apply multivariable analysis techniques in search of the most relevant parameter for Araucaria regeneration. This study used the following methods: principal component analysis (PCA), forward stepwise regression modeling and Maxent modeling.
