Aldred, James. 2017. The Man Who Climbs Trees. A Memoir. London. Penguin Random House.
To be released in North America by Houghton Mifflin Harcourt in 2018.

Most arborists are aware of tree climbing as a work activity, and a few climb trees as a form of recreation. James Aldred has made a successful career out climbing trees for exploration and filming, and his book provides a gripping read. Many of us know the hard work involved in getting into a tree and can appreciate the blood, and sweat, and dirt that often comes with the task. Aldred’s narrative adds a few layers of additional horror as he describes setting up camera placements and platforms for filming all sorts of nature documentaries for well-known luminaries such as David Attenborough.

Every so often new books come out that provide a fresh perspective on well established themes. This latest offering by Wiley is one such example. All of the fifteen contributors are based in Germany, and the source material offered is very much European – a good thing as it introduces perspectives, examples, and case studies less commonly seen in North America.

Book: The CODIT Principle. Implications for Best Practices.

Learn more about Julian Dunster.

It is a while since there has been a new book about CODIT. The CODIT Principle. Implications for Best Practices provides a welcome update and draws together old and new. It was originally published in Germany in 2008, and this translation brings a lot of useful material to a wider audience.

The seven chapters cover Introduction, The Basics of Tree Biology, The Wound Reactions of Trees, CODIT: From Model to Principle, The CODIT Principle – Considerations and Implications for Tree Care, Best Practices for Crown Pruning, and The Wound Reactions of Bamboo and Palms. There are excellent colour images and diagrams throughout.

Inevitably, given the breadth of the topic, some parts are covered quite briefly, and given that seven years have elapsed since the book was originally published, it is possible that some details have already been superseded by new research results. The issue of drill holes, and which technique is more damaging (increment core or resistance drilling) is one such example. The use of wound dressings is another. Originally dismissed by Shigo as not useful, more recent work discussed in this book clearly demonstrates that they can be useful on some species at some times of year, but that debate is ongoing.
