Vessel-related mortality of sea turtles in Queensland, Australia

Identification of threats is a standard component of conservation planning and the ability to rank threats may improve the allocation of scarce resources in threat-mitigation programs. For vulnerable and endangered sea turtles in Australia, vessel strike is recognised as an important threat but its severity relative to other threats remains speculative. Documented evidence for this problem is available only in stranding records collected by the Queensland Environment Protection Authority. With the authority’s support we assessed the scope and quality of the data and analysed vessel-related records. We found adequate evidence that during the period 1999–2002 at least 65 turtles were killed annually as a result of collisions with vessels on the Queensland east coast. This level of mortality appears broadly comparable to that recorded in the Queensland East Coast Trawl Fishery before the introduction of mandatory turtle-exclusion devices in that fishery. Green turtles (Chelonia mydas) comprised the majority of vessel-related records, followed by loggerhead turtles (Caretta caretta), and 72% of cases concerned adult or subadult turtles. The majority of vessel-related records came from the greater Moreton Bay area, followed by Hervey Bay and Cleveland Bay. The waters of all three areas are subject to variable levels of commercial and recreational vessel traffic, and their shores are both populated and unpopulated.

NORM IN THE OIL AND GAS INDUSTRY— EXPOSURE ASSESSMENT AND MANAGEMENT PLAN

Naturally Occurring Radioactive Material (NORM) is an inevitable by-product of petroleum exploration and production. It is produced with the reservoir fluids and is typically found in low concentrations, but potentially high volumes. However, Victorian regulations that cover NORM are based on acceptable public exposure to ionising radiation and appear to be formulated around high concentration, low volume sources such as those found in medical procedures.Esso Australia Pty Ltd conducted a comprehensive exposure assessment study to establish limits for NORM. The two-year study was carried out in conjunction with the regulators (Victorian Environment Protection Authority, Department of Human Services, and Australian Radiation Protection and Nuclear Safety Agency) and included other key stakeholders like employees and suppliers.This paper provides a discussion of the management plans for, and the results of, assessments undertaken to quantify any potential risk of handling and disposing of NORM material in the environment. The assessments demonstrate that exposure to NORM released into the environment from Bass Strait oil and gas operations does not present a radiological hazard to workers, the general public, or ecological receptors. In fact, it represents less than 1% of Australian and internationally accepted limits for such exposure.

The Allen Strom Eureka Prize for Environmental Education 2000 and 2001

In the five years since the NSW Environment Protection Authority sponsored the first $10,000 Allen Strom Eureka Prize for Environmental Education, there has been a perceptible climate change in the context for environmental education. Although the aim of the award—‘to encourage and reward excellence in the design, implementation and evaluation of environmental education programs’—remains relevant and has not been amended since 1997, many readers might be asking, ‘what, no mention of sustainability?’Those who promote education for sustainability (EfS) see it as a powerful and embracing framework for environmental education and their efforts have gained momentum within a number of critical areas: in the professional and research literature (including, of course, the AJEE), within policies at international, national, state and local levels, and within professional discourses and practices. However, EfS has rolled out very much as a work in progress and there is, as yet, no orthodoxy (thankfully!) about exactly what the term encompasses.

Interrogating Silence: Environmental Education Research as Postcolonialist Textwork

In December 1997 I was privileged—and very pleasantly surprised—to receive the inaugural Allen Strom Eureka Prize for Environmental Education for ‘environmental education research of a substantive nature which contributes to professional thinking and practice’. According to the program for the prize-giving ceremony, I was awarded the prize ‘for research on recent cultural and philosophical movements, such as postmodernism, which has translated and applied complex social theories to theory and practice in environmental education’.I want to take this opportunity to repeat my thanks to the New South Wales Environment Protection Authority for their generous sponsorship of this prize. I offer these thanks not only as an individual recipient but also on behalf of the wider Australian environmental education community. I see particular significance in the Allen Strom Eureka Prize for Environmental Education being awarded in a suite that includes separate prizes for environmental research and environmental journalism. This helps to distinguish our field from other disciplines with which it is sometimes confused. My own research emphasises that environmental education is not just another type of environmental study but more a form of cultural and media literacy.
