Whether conservation biologists should engage in advocacy has been a controversial topic for many years. I argue that conservation biologists should acknowledge their primary responsibility in a civil society as informed citizens possessing specialised knowledge and should aim to influence conservation policy through a variety of communication channels.

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.

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.

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.

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.

By analysing a cross section of 118 statements published over 187 years, we differentiate seven discourses to describe the history of forest management in the tall forests of south-western Australia. Management for a more comprehensive set of values would acknowledge a new moral consensus.

This essay is a zoologist’s response to Zoopolis. A political theory of animal rights. A point of agreement is that animals deserve more than being over-ridden by human interests. A stalling point is the animal rights agenda, which rules out animal research as morally illegitimate.

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.
