David Lindenmayer is the renowned specialist on the critically endangered Leadbeater’s Possum and the Mountain Ash forests that are their home. He has collaborated with other researchers to produce a book which looks at the possums future in light of fires and logging.
While it is expensive (almost $60) it is an incredibly important contribution to our knowledge about these forests. It is available from the CSIRO.

Less than two hours’ drive from the centre of Melbourne, the towering skyscrapers of the city are replaced by giants of a different kind: the Mountain Ash. These remarkable trees are the tallest flowering plants in the world and the forests they populate are home to Victoria’s only endemic mammal, the critically endangered Leadbeater’s Possum. Despite making up some of the most spectacular landscapes Victoria has to offer, montane ash forests are currently facing threats on two fronts: fire and logging.
The authors of Mountain Ash, professors and researchers at the Australian National University, know the montane ash forests of the Central Highlands of Victoria intimately. ANU research has been conducted in the region for more than 30 years; it is the longest-running environmental study in the world. The authors’ aim to distil decades of research within a 150-page book could have resulted in a dense account of their findings, but this is not the case. Instead, the authors have created a vivid and accessible narrative describing the challenges facing Victoria’s giant forests.
This publication utilises images in abundance to create a visual reference for the reader; the accompanying captions provide just as much insight as the body of the text. These images allow the reader to see for themselves the patterns of fire across the forest, the differences between old growth and post-logging regrowth, and between areas of forest burned at varying severity. These images are an invaluable tool to understanding the text, but at all times the authors communicate their subject clearly and with enthusiasm.
Beginning with an overview of the Black Saturday fires and the flora of the forest, the book goes on to examine the responses to fire of possums, gliders, birds, invertebrates and small terrestrial mammals, as well as the impacts upon large old trees and carbon stocks. Finally, recommendations are made for the forest’s future management. In succinct descriptions broken up by ‘myth-busting boxes’, diagrams and many photos, the book spells out clearly the extent of the destruction that has already occurred in our forests and how further damage can be avoided.
Uniquely placed by their ongoing research to examine the same areas of forest in detail both before and after the Black Saturday fires, the authors are able to offer a comprehensive view of the destruction caused by fire. Intriguingly, they have discovered that the cycle of logging in montane ash forests actually enables further damage by fire, in turn degrading the habitat of the Leadbeater’s Possum, for which large old hollow-bearing trees are vital habitat.
Mountain Ash is essential reading for all Victorians. It alerts the reader to the degradation of the crucial habitat of our faunal emblem, the Leadbeater’s Possum, and an iconic tree species, the Mountain Ash. The closing chapters indicate that change is possible as well as necessary to ensure that our forests are protected; reading this book is only the first step towards joining the cause.
This book belongs on your bookshelf if… you’ve ever felt enchanted by the forest.
