Academic Editor: Steven Jansen Received: 7 April 2015 / Accepted: 3 June 2015 / Published: 9 June 2015 Abstract: Globally, drought and heat-induced forest disturbance is garnering increasing concern. Species from Mediterranean forests have resistance and resilience mechanisms to cope with drought and differences in these ecological strategies will profoundly influence vegetation composition in response to drought. Our aim was to contrast the early response of two co-occurring forest species, Eucalyptus marginata and Corymbia calophylla, in the Northern Jarrah Forest of southwestern Australia, following a sudden and severe drought event. Forest plots were monitored for health and response, three and 16 months following the drought. Eucalyptus marginata was more susceptible to partial and complete crown dieback compared to C. calophylla, three months after the drought. However, resprouting among trees exhibiting complete crown dieback was similar between species. -

By EurekAlert! Australia's giant eucalyptus trees are the tallest flowering plants on earth, yet their unique relationship with fire makes them a puzzle for ecologists. Now the first global assessment of these giants, published in New Phytologist, seeks to end a century of debate over the species' classification and may change the way it is managed in future. Gigantic trees are rare. Of the 100,000 global tree species only 50, less than 0.005 per cent, reach over 70 metres in height. While many of the giants live in Pacific North America, Borneo and similar habitats, 13 are eucalypts endemic to Southern and Eastern Australia. The tallest flowering plant in Australia is Eucalyptus regnans, with temperate eastern Victoria and Tasmania being home to the six tallest recorded species of the genus. -

Proteaceae (Banksia Species)
Proteaceae (Banksia Species) Information: 90% of all Banksia species occur in South Western Australia. The two most com- mon Banksia species in the Perth region are the Firewood Banksia (Banksia menziesii) and the Slender or Candle Banksia (Banksia attenuata). These two species each flower throughout the two halves of the year and are an important source of food for countless animals. Large Banksias such as these as well as B. grandis, B. ilicifolia B. Prionotes and B. littoralis produce an abun- dance of nectar from their large flower spikes that sustain countless species and have traditionally been used as a source of food and drink by indigenous Australians. Banksias are highly adapted to a nutrient poor environment with harsh, dry climate having sunken stomata to preserve water and cluster roots to enhance nutrient uptake in Phosphorus deficient soils.

Price Candle Banksia (Banksia attenuata) feeding a Honey Possum (Tarsipes rostratus) Picture courtesy of Kwongan Foundation Associated Life: Many animals drink nectar from Banksia flower heads including Perching birds such as Honeyeaters, Spinebills, robins and Wagtails as well as the Honey Possum, the worlds only nectarvorious marsupial.

Bennett's Mallee
Advice to the Minister for the Environment and Heritage from the Threatened Species Scientific Committee (the Committee) on Amendments to the list of Threatened Species under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Scientific name (common name) Eucalyptus bennettiae (Bennett’s Mallee) A genetic analysis of Eucalyptus bennettiae confirmed that it is a hybrid between Eucalyptus sporadica and Eucalyptus lehmannii (Walker 2002). 2. Description Bennett’s Mallee is a small mallee up to 2.5 metres in height with smooth bark (WA Herbarium 2005). It has a morphology similar to its two parents, Eucalyptus lehmanii and Eucalyptus sporadica (Brown et al. 1998). It grows on red quartizite rocky slopes and in red loam gullies (Brown et al. 1998; WA Herbarium 2005). It flowers between June and September, and also in December (Kelly et al. 1995). 3. National Context Bennett’s Mallee is endemic to Western Australia, and is known from a small area on the south coast between Albany and Esperance. It occurs near Ravensthorpe and the Fitzgerald River National Park and co-occurs with its parent species, Eucalyptus sporadica and Eucalyptus lehmannii (CALM 2005; Walker 2002). One parent species, Eucalyptus lehmannii, is widely distributed in the south coast region, from west of Albany to east of Esperance. Similarly, the other parent species, Eucalyptus sporadica, is widely distributed in the south coast region from Albany to east of Esperance, and also occurs in parts of the central and eastern wheatbelt. Bennett’s Mallee is not listed under the Western Australian Wildlife Conservation Act 1950. The parent species, Eucalyptus lehmanii and Eucalyptus sporadica, are not listed under the Western Australian Wildlife Conservation Act 1950 or the EPBC Act. -

Ruthrof, Giles St. J. Hardy Centre of Excellence for Climate Change Woodland and Forest Health, Murdoch University, Perth, Australia Email: [email protected] Received June 7th, 2012; revised July 10th, 2012; accepted July 25th, 2012 Ecosystems in Mediterranean climate regions are projected to undergo considerable changes as a result of shifting climate, including from extreme drought and heat events. A severe and sudden dieback event, occurring in regionally significant Eucalyptus gomphocephala woodland in Western Australia, coincided with extreme drought and heat conditions in early 2011. Using a combination of remote sensing and field- based approaches, we characterized the extent and severity of canopy dieback following the event, as well as highlighted potential predisposing site factors. An estimated 500 ha of woodland was severely affected between February and March 2011. Tree foliage rapidly discolored and died over this period. In the af- fected portion of the woodland, approximately 90% of trees greater than 20 cm DBH were impacted, while in the adjacent unaffected woodland 6% showed signs of damage. Tree density in the unaffected area had approximately 4.5 times more trees than the affected woodland. Precipitation drainage patterns are thought to explain the difference between affected and unaffected woodland.
