Artificial Fractures & Coronet Cuts (fact sheet): https://shorturl.at/8EZrX
In the summer of 2020, PNW-ISA created Arbor Chat, a webinar series that features topics led by industry professionals who are testing theories, challenging practices, sharing research or questioning controversial methods while savoring their favorite cup of Joe. Each webinar lasts 30-minutes to one hour in length although some topics may warrant additional time. We encourage members to participate in this new forum that will not only expand your arboriculture knowledge but allow you to gain CEU’s too!

This Arbor Chat webinar makes a case for the acceptance and tolerance of natural fractures and the implementation of artificial fractures, followed by a live Q & A session. The presenter, David Restrepo, is an arborist working for the Tree and Woods Service of the City of Paris, assigned to the Vincennes Woods division, the only municipality in France where natural and artificial fractures are not only allowed, accepted and tolerated, but they are also encouraged by the hierarchy. A practice still regarded by many, worldwide, as a controversial method.

The Tree and Woods service of the City of Paris is also undertaking a long term research protocol on coronet cuts set and monitored by Christophe Drénou, PhD in tree architecture, specialized in tree decline, tree senescence and remarkable trees and, Laurent Larrieu, PhD in dendromicrohabitats, leading researcher in the field.
David Restrepo will make his case, challenging today’s pruning standard practices, presenting a fact sheet which highlights essential points in order to understand and lead to the acceptance and tolerance of natural and artificial fractures. It covers the why, when and how, supported by the philosophy, theory and practice behind it.
The fact sheet presented by David Restrepo was developed as the foundation of a handbook on fractures that he is writing on behalf of COPALME, the French-speaking arborists think-tank and exchange. It's a means to make available the pertinent information on the topic in a coherent, comprehensible and accessible way so that it can be assimilated, applied, and transmitted. The acceptance and tolerance of natural fractures and the implementation of artificial fractures, requires deep understanding of a wide variety of concepts drawn from a variety of fields. These include tree architecture, anatomy, biomechanics, mechanobiology, mechanoperception, ecology, biodiversity, aesthetics, arboreal management, tree risk assessment and pruning practices. We may grasp the concept easily, if we are sensitive to nature and if we are passionate about trees. But there's a gap between grasping the concept for oneself and transmitting it to others, so that they can accept and tolerate fractures in their turn. So we must go beyond our personal understanding. We must acquire the means to transmit the essence of it to others in a practical accessible way, if we care to implement fractures into our practice.
It's been two decades that fractures have been implemented as part of the management of arboreal patrimony in the UK and carried out by many arborists worldwide. It's also been over three decades that we've been carrying out a war against stubs, whether as a result of natural fractures or artificial pruning. It's about time we adopted a new perspective on fractures in specific situations and exceptional pruning scenarios. If you are still hesitant and need appropriate information to be reassured, or if you need to reinforce your understanding on this topic, this is what this talk is all about. The way in which the information is laid out in a coherent and practical fashion will give you the means not only to understand, but to transmit the information to others so that you can implement it.
