  - Research Findings 2011: Marri flowering threatened by introduced pathogen
  Over recent years, the declining health of marri (Corymbia calophylla) in southwest WA has been an increasing source of concern. These trees provide important flowering resources and the damage to flowers is likely to cause substantial losses of foraging resources for native fauna as well as honeybees.

  - Research Findings 2011: Can a microscopic plant pathogen kill a large tuart tree?
  Since the 1990s, tuart (Eucalyptus gomphocephala) have been suffering a significant decline in Yalgorup National Park, approximately 100km south of Perth Western Australia, with symptoms ranging from chronic deterioration to sudden mass collapse.

  - Research Findings 2011: Tree water relations in a drying climate
  Mean annual rainfall in Australia's southwest has decreased dramatically during the last few decades and this trend is predicted to conti nue under current climate change scenarios. 2010 was the driest year on record in southwest WA, and was followed by one of the hottest summers ever. These extreme events have caused severe crown decline in jarrah (Eucalyptus marginata) in many places. Our research targets the dynamics of water relations in jarrah trees and other important woody species of the jarrah forest.

  - Research Findings 2011: Is Eucalyptus wandoo health aff ected by climate change?
  Southwest Western Australia (WA), known for its high biodiversity, has experienced a decline in rainfall since the early 1960s, and the projections are unanimous that this trend will continue. This trend, together with the global increases in temperature and more frequent extreme weather events like drought, is having an increasingly negative impact on the health of the diverse forest ecosystems in this region.

  - Research Findings 2011: Understanding restorati on volunteering in a context of environmental change
  A range of human activities have left their impact on the landscape of southwest WA, including - but not restricted to - climate change. Various experts have argued that it is impossible to return these already drastically altered ecosystems to what they once were, and that future climatic changes may render such historical landscapes obsolete. However, it has also been suggested that society expects a return to particular (historical) ecosystem states.

  - Research Findings 2011: Impact of tuart canopy decline on brushtail possums
  Since the early 1990s, there has been a noticeable decline of the health of tuart (Eucalyptus gomphocephala) in Yalgorup National Park in Western Australia. The exact reason for the decline is unknown although there have been multiple theories put forward such as land clearing for agricultural and urban development, decreased rainfall and pathogens such as native cankers and Phytophthora spp. Although some of the tuart trees are recovering from the decline, the change to vegetation structure in the tuart forest has been extreme.

  - Research Findings 2011: Is tree health a determinant of reptile species richness and abundance?
  Large portions of the world's forests and woodlands are currently affected by declining tree health, however the effects of these tree declines on fauna communities is largely unknown.

  - Research Findings 2011: Look before you plant: the use of smoke water to test the soil seedbank
  Land managers are often faced with a high degree of uncertainty regarding the level of weed species in the existing soil seedbank. This can make strategic land management planning difficult. If the soil seed bank could be analysed, it may be used as a predictive tool for land managers.

  - Research Findings 2011: Revegetating harsh environments: lime and cement kiln dust residue areas
  Revegetating some landscapes may be more challenging than others. Previous land use may dramatically affect soil composition and structure, which can influence survival and growth of vegetation planted at these sites. These landscapes may often require a tailored approach to revegetation, which takes these factors into account.

  - Research Findings 2011: Testing techniques for promoting revegetation: mimicking the effects of fire
  Marlee Reserve is a major area of remnant woodland in the Mandurah area. This 48ha reserve encompasses beautiful Eucalyptus-Banksia woodland with high conservation, social, and educational values. However, a number of areas are degraded. Revegetation is one way of assisting recovery in these degraded areas. In a drying climate, however, merely planting seedlings may not be sufficient to ensure vegetation recovery. Therefore new methods to increase the success of revegetation need to be found.

  - Research Findings 2011: Overcoming challenges to restoration
  Since European settlement, large areas of Australia have been degraded by various anthropogenic disturbances. This large-scale degradation has lead to a growing desire from the community, conservationists, scientists and land managers to develop techniques to restore these areas. However, restoration faces a range of ecological, economic and social challenges which need to be overcome to ensure restoration projects are successful in the long term.

  - Research Findings 2011: Impact of Phytophthora dieback on reptiles in banksia woodlands
  Phytophthora cinnamomi is a soil-borne water mould (Class Oomycetes) that is listed by the IUCN Species Survival Commission as one of the world's 100 most devastating invading species. Consequences of Phytophthora infestation include loss of susceptible plant species, reduction in primary productivity and biomass and changes to habitat structure.
  These changes in floristic communities and vegetation structure are likely to have consequences for fauna.

  - Research Findings 2011:Tree crown deaths over winter 2010: the effects of frost on marri and jarrah
  In July 2010, scientists and community became aware of alarming changes to tree crown health within pockets of marri (Corymbia calophylla) and jarrah (Eucalyptus marginata)-dominated forest. Severe shoot and foliage mortality was reported throughout large porti ons of the north-western jarrah forest, with marri suffering foliage dieback on the crown periphery and jarrah leaves first turning distinctly purple in colour prior to dying and shedding.

  - Research Findings 2011: Role of Australian digging mammals in ecosystem health
  Mammals that move or manipulate soil for food or to create shelter can completely change the biotic and abiotic characteristics of their habitat, potentially creating multiple benefits to the overall health of the ecosystem. The main digging mammals within Australia, bandicoots and bettongs, create small, conical-shaped holes while foraging for underground fungi, earthworms and tubers. The majority of Australian digging mammals have undergone drastic range and populati on contractions within the last 100 years. Where ecosystems have lost digging mammals, key processes may be reduced and this may contribute to declines in ecosystem health. Our project will investigate the ecological impacts of mammal foraging pits on soil condition, water infiltration, seedling recruitment, fungi dispersal and fire dynamics.

  - Research Findings 2011: Using 'nature's kidneys' to treat alkaline waste water
  Constructed wetlands are surface or subsurface water bodies designed to include a series of physical, chemical and biological processes which recycle wastewater. However, in addition to minimising the environmental footprint and improving aesthetics of the industrial landscape, constructed wetlands and their surroundings also provide a economic, social and environmental benefits and services, including habitat for a wide range of animals and a place for people to enjoy and connect with their environment.

  Environmental changes such as reduced vegetation cover and altered plant species composition can have serious consequences for ecosystems, and can lead to the extinction of animal species.
