Many terrestrial orchid populations in southern Australia are threatened by the noxious environmental weed Asparagus asparagoides. This paper describes a safe method of applying herbicides to control this weed in populations of the threatened terrestrial orchid Pterostylis arenicola. The technique of weed wiping is particularly suitable for use in areas of high conservation concern.

PC17027Predicting the occurrence of an endangered reptile based on habitat attributes

pp. 12-24

The endangered Blue Mountains water skink is restricted to highland peat swamps in eastern Australia. We show that Eulamprus leuraensis were found at sites with higher soil moisture, more burrows and live vegetation and a denser understorey. We developed a quick field detection method to assess the likely presence of the species, and mapped its known and predicted habitat using GIS.

PC17042Diets of native and introduced apex predators in Hawai'i

Carolyn S. Mostello and Sheila Conant
pp. 25-34

This paper describes diets and dietary overlap in four apex predators in Hawai‘i: pueo, barn owl, cat and mongoose, based on analysis of the contents of owl pellets and cat and mongoose scats, which were collected from eight different areas on five of the Main Hawaiian Islands.

Koa (Acacia koa) reforestation areas (KRAs) on Hawaii Island are structurally similar to nearby intact forests in some cases, though species composition differs. Koa reforestation areas may provide a conservation benefit by re-establishing forest structure on degraded pasture. Some KRAs harbour understorey species as well.

PC17039Coyote diet patterns in the Mojave Desert: implications for threatened desert tortoises

pp. 44-54

Coyote predation on threatened desert tortoises was examined near Barstow, California, during 2009–14. On the basis of analyses of coyote scats, predation on tortoises appeared to be primarily opportunistic and was little influenced by the availability of other food items.

We investigated denning home range and movement patterns of 10 cuscus using radio-telemetry in and around a 21-ha forested tambu area over a 28-day period. Home-range size was highly variable and log-normally distributed (mean = 2.9 ha). We conclude that similar sized tambu areas are too small to be self-sustaining.

Eastern grey kangaroo populations have declined in many areas of the South East Queensland bioregion of Australia, a region that has undergone high rates of urbanisation. Further declines can be anticipated and processes of urbanisation, including higher human population growth rates and smaller areas of natural habitat retained, were predictors of kangaroo decline.

Mulga birds allocated foraging resources similarly to other bird communities, with species differing in foraging behaviours and substrates. Foraging behaviour and species assemblages were sensitive to rainfall and associated changes in the abundance and type of prey available, with nomadic species departing as rainfall decreased.

Although mulga is floristically and structurally diverse, the composition of the avifauna is consistent. In years of high rainfall, nine foraging guilds were shared between mulga sites in Western Australia and the Northern Territory. However, guilds differed between locations in species assemblages, with species allocated to different guilds during years of low rainfall.

PC17038Are there conservation implications for kangaroos feeding on sea birds?

Michael Hughes and Valériane Bérengier
pp. 98-99

This research note documents an observation of a wild western grey kangaroo (Macropus fuliginosus) feeding on a dead silver gull (Chroicocephalus novaehollandiae). We consider why the kangaroo may be feeding on the dead gull and possible implications for conservation programs relying on poison meat baits to control introduced species.

PC17036Dingo singing: the howl of the advocate

Angela Wardell-Johnson, Clare Archer-Lean and Jennifer Carter

Advocacy in World Heritage protected areas is challenging traditional management. Contextualised analysis compared advocacy on behalf of the K’gari-Fraser Island dingo in the management community with the research community. Advocacy in scientific discussion is crucial for negotiation to achieve conservation outcomes acceptable to managers in a World Heritage context.

PC17025Values, credibility, and ethics: public advocacy and conservation science

Harry F. Recher

Conservation scientists need to be public advocates for creating economies that are ecologically sustainable. In addition, they must assume a role of leadership in the development of global environmental policies and the creation of a world where all species share the Earth’s resources. At present that world does not exist.

PC17033An advocate for taxonomic research in Australia

Pat Hutchings

This opinion piece explains the importance of taxonomy and why it is critical to actually identify species. However, the ability to be able to do this is declining here in Australia and we desperately need to rectify this situation. We taxonomists need to become better advocates for our discipline and better explain to our colleagues and the general public why taxonomy is useful. We need to develop illustrated guides and develop online guides, with websites that are widely marketed and can be useful for other scientists as well as the general public.

PC17015Preparing for advocacy, resisting attack

Brian Martin

Some scientists who engage in public advocacy come under attack. It is worthwhile preparing by learning about the risks, increasing financial security and building networks for personal support. When under attack, it is important to document actions, seek advice and mobilise support. Supporting outspoken scientists protects scientific freedom for all.

PC17014The reverse precautionary principle: science, the environment and the salmon aquaculture industry in Macquarie Harbour, Tasmania, Australia

Jamie B. Kirkpatrick, Lorne K. Kriwoken and Jennifer Styger

Benthic waters of Macquarie Harbour, Tasmania de-oxygenated as fish production grew. The reverse precautionary response was to undertake further research because the causes of the changes were not fully understood. To help avoid such a response, research on the environmental impacts of an industry needs to be undertaken by scientists in secure positions funded independently of industry and government.
