McCalman, during this period, also began exploring the environment through humanities as well as interdisciplinary practices. A defining example of this approach is found in the introduction of the 2014 book “Rethinking Invasion Ecologies from the Environmental Humanities”.Frawley, J. and McCalman, I., 2014. Rethinking invasion ecologies from the environmental humanities. London: Routledge. p.4. McCalman and his co-editor, an environmental historian, argue for the value of examining invasive flora and fauna through the lens of the humanities given that the transfer or introduction of species involve, not just biology, but human and cultural elements. The majority of the book, thus, is dedicated to “demonstrating how research derived from a humanities perspectives can transform our understandings of the character and implications of invasion ecologies”. McCalman has, in his solo works since then, adopted this humanities-based approach to discussions surrounding the environment. Such works include 2013 book “The Reef: A Passionate History”.McCalman, I., 2013. The Reef: A Passionate History. Melbourne: Penguin Australia.
