Blue Gum

In the mid-1990s commercial Tasmanian blue gum (Eucalyptus globulus) plantations were established in south-west Western Australia. We examined the extent of loss of potential nesting trees for an endangered obligate hollow-nesting cockatoo, Muir’s corella (Cacatua pastinator pastinator), resulting from establishment of these plantations during 1995–2004. Clearing of native vegetation was extensive in both Tonebridge (51%) and Frankland (76%) study sites. The proportion of land used for timber plantation increased significantly from 2.4% to 12.1% (Tonebridge) and 0.5% to 9% (Frankland) in the period 1995–2004. Plantations were predominantly established on already cleared farmland, but during the rapid development of plantations, large numbers of remnant paddock trees (mean = 56%) in cleared farmland were removed. Despite the loss of more than 50% of potential nesting habitat over an area of 376km2 within its current distribution, Muir’s corella continued to increase in numbers. However, there are concerns about delayed impacts of the clearing of potential nest trees we have observed, and consequences of further tree loss during future plantation harvesting. Evidence-based demonstration of biodiversity protection is increasingly needed to fulfil forest and plantation stewardship requirements, so greater care needs to be directed towards the management of extant remnant vegetation in paddocks.

Special Expertise

Throughout history, gardens and garden designing has been in the attention of Persian architects who had special expertise in the construction of gardens. The appearance of Islam and allegories of paradise taken from that in Koran and Saints’ sayings gave spirituality to garden construction. Climate conditions have also had an important role in this respect but little research has been done about it and most of the investigations have referred to spiritual aspects and forms of garden. The cold and dry climate that has enveloped parts of West and North West of Iran has many gardens with different forms and functions, which have not been paid much attention to by studies done so far. The aim of this paper is to identify the features and specifications of cold and dry climate gardens with an emphasis on Tabriz’s Gardens.  Due to its natural and strategic situation, Tabriz has always been in the attention of governments throughout history; travellers and tourists have mentioned Tabriz as a city that has beautiful gardens. But, the earthquakes and wars have left no remains of those beautiful gardens. This investigation, by a comparative study of the climates in Iran and the effect of those climates on the formation of gardens and garden design, tries to identify the features and characteristics of gardens in cold and dry climate. The method of study is interpretive-historical on the basis of written documents and historic features and field study of existing gardens in this climate. The results show that, with respect to natural substrate, vegetation, the form of water supply, and the general form of the garden; gardens in dry and cold climate are different from gardens in other climates.

Significant Difference

The parasite, Nosema apis, was found to be widespread among feral populations of honey bees (Apis mellifera) in the south-west of Western Australia. The location, month of collection and whether the feral colony was enclosed in an object or exposed to the environment, all affected the presence and severity of infection. There was no significant difference in the probability of infection between managed and feral bees. However, when infected by N. apis, managed bees appeared to have a greater severity of the infection.

This case study research examines informal adult learning in the Lock the Gate Alliance, a campaign against mining for coal seam gas in Central Gippsland, Australia. In the field of the campaign, circumstantial activists learn to think critically about the environment, they learn informally and incidentally, through socialization with experienced activists from and through nonformal workshops provided by the Environmental Nongovernment Organization Friends of the Earth. This article uses Bourdieu’s “theory of practice,” to explore the mobilization of activists within the Lock the Gate Alliance field and the practices which generate knowledge and facilitate adult learning. These practices have enabled a diverse movement to educate the public and citizenry about the serious threat fracking poses to the environment, to their land and water supply. The movements successful practices have won a landmark moratorium on fracking for coal seam gas in the State of Victoria.
