Considering the decisive role of water in living processes of plants, appropriate water supply is a key factor for successful urban tree management. In trees, insufficient tissue hydration leads to decreased vitality and increased susceptibility to pathogens and pests. Monitoring of tree water relations provides an insight into both instant and long term tree response to environmental conditions.
Sap flow measurements can reveal differences in water conductivity and functionality of xylem tissues in distinct parts of a tree. For example, we can distinguish roots by their importance in water supply facilitating decision making for appropriate root pruning. Also, the effect of mechanical damage of roots causes changes in radial sap flow pattern. Thus, tree hydraulic redistribution can be traced, showing the course of compensation of sudden water deficiency by well hydrated roots. By applying such techniques, we can follow the course of tree preparation for transplantation, subsequent recovery, etc.
Effect of urban microclimate on tree vitality can be controlled by defining both most appropriate and critical conditions for sufficient hydration of individual trees. For example, high nocturnal sap flow following rainy day indicates night-time recovery after water deficit emerging during previous days. A decrease in sap flow during hot days can indicate water deficit. Monitoring of tree reaction to environmental changes provides important information that can be successfully applied in practice.

• Consider what makes this generation of employees different from the past
• Find out why recruitment is too expensive and virtually ineffective
• Discover why management styles that have worked for 200 years suddenly don’t
• Learn how to develop your people and get the best from every employee
Solving the "people problem" is the underlying factor to every business hurdle and frustration today. While pressing issues in the past have focused on sales, profitability, or recruitment, we are operating in a new economy and management ability is the essential key to success.
Trees in urban areas are assets to those communities. Effectively maintaining and preserving those trees is difficult, though, because the interactions between all living things and their environment are dynamic relationships, and the responses of living things to changes in their environment are unpredictable as a result. Increasingly, Geographic Information Systems (GIS) are being used to support urban forest management because they can store location information and be updated and shared easily, which are basic necessities for any tool used in managing the ever-changing urban forest.
Six years ago, we never used a GIS for our arboricultural work. As time went on, and the projects became more complex, it was clear that there had to be a more efficient way to do the basics if we wanted to stay competitive and give our clients a decent product. The process of collecting arboricultural data on a non-weatherproof PDA while eyeballing the tree locations using printed, large-scale surveys was slow and error prone. Through trial and error, asking questions and determination, we completely changed our workflow so that the hub was the GIS. This change has likely saved hundreds of person-hours in the field and in the office and improved the quality of our work.
Using our firm’s experience as an example, I will demonstrate how easy and valuable integrating a GIS into your workflow can be. I will discuss some GIS basics, some options available to get started and expand with, and some processes to help get consistent, good quality results. Ultimately, a GIS can make many peripheral tasks simpler, helping you focus more attention on the trees.
Recent work in the field of tree biomechanics has helped inform and modernize the new ANSI Tree Risk Assessment standard and ISA Best Management Practices. This presentation will provide an overview of recent advancements from North America and beyond in the field of tree biomechanics including a participant’s perspective on Tree Biomechanics Week 2010 and 2013 and new studies utilizing NASA developed camera technologies to assess stresses in trees.
This presentation will be given from the perspective of a practitioner and participant. Starting with the Tree Structure and Mechanics Conference in 2001, a series of conferences, research projects and scientific/educational gatherings have occurred to address different aspects of tree biomechanics. This includes Tree Biomechanics Weeks in 2010, 2013 and 2016. The presenter has been actively involved in many of those events and will share that experience with the audience through images, research results and videos. The audience will gain greater understanding of the research that has been underway and continues today and how that information may be transferable to the practice areas of risk assessment and conservation arboriculture – the management of aging trees. This talk has been previously presented at The Arboricultural Association’s 49th Annual Amenity Arboriculture Conference, 8-11 September 2013, University of Exeter, UK, the ISA European Congress, May 26-28, 2014, Turin , Italy, the Canadian Urban Forest Conference, Victoria, BC, September 30 – October 3, 2014, the SIAQ Congress, Montreal, Quebec, October 31, 2014, International Society of Arboriculture West Coast Chapter Annual Conference, Yosemite, California, April 30, 2015, and the Arboriculture Australia National Conference, June 1, 2015, Adelaide, Australia.
In line with morphological parameters of trees, such as crown symmetry and projection, branching angle and attachment, forks etc., stability of trees is largely affected by its health status. Mechanical injuries, such as bark stripping, interferes conductive systems of trees and facilitate spreading of fungal infections into stems, reducing vigour and competitiveness already within a few years, thus leading to decline. Similarly to forest stands, in the urban areas, bark stripping is a common tree mechanical injury caused by human activities.
Weakened trees are considered to have reduced stability leading to increased risk of wind damage, still this issue has not been comprehensively assessed. In this study, we used static pulling tests to analyse the effect of bark stripping on stability of 40-years-old Norway spruce trees growing in an even-aged stand. Anchorage, bending moment at both primary failure and at the collapse were assessed and related to morphometrics of trees.
Negative effect of bark stripping on stability of individual Norway spruce trees was evident; all of the calculated stability parameters were significantly (p<0.05) reduced by the wildlife damages. However, no significant differences in morphometric parameters of the above-ground parts of trees were observed, suggesting that tree stability was influenced by root condition, likely due to fungal infections (root rot).

Have you ever found an insect and had no idea what it was? Was it a predator, a beneficial species, or perhaps a new invasive pest? Take part in a 2-day workshop filled with interactive activities designed to sharpen your scouting, identification and management skills for pests and beneficial insects of trees and shrubs. The workshop will take place in the tranquil, natural learning environment of the Queens University Biological Research Station (just north of Kingston). Motivated by their contagious passion for learning, Marvin Gunderman, Dave Cheung and Jen Llewellyn will lead the workshop in an inspiring, engaging, team building style filled with humour and fun.
The workshop is made up of a series of engaging lectures that covers the diversity of insect orders with emphasis on the major orders (Coleoptera, Diptera, Hymenoptera, Lepidoptera and Hemiptera). You will learn about the grotesque nature of parasitic wasps, discover the amazing diversity of flies, be fascinated by the lifecycle of host switching parthenogenic gall-making aphids and much more. After the lectures test your new gained knowledge with one of the many interactive team-based games.
Whether it’s the fast-paced identification game Speed-ID or strategy-filled Insect Guess Who, you and your team are guaranteed to have a great time while learning lots in the process. At the end of the workshop, lies one final group challenge that puts everything you learned to the test, including your identification, scouting and collecting skills!

As a boy Dave spent most of his time chasing insects with an aquarium net, taking apart electronics, and tinkering on the computer. Today, he still chases insects and fiddles with technology, although these days with a bigger net and a much faster mobile computer.
Dave’s passion is to help people create a stronger connection to the natural world by combining photography, visual design, technology, and science education. Whether it’s through a website, a mobile app, or in the classroom, Dave thrives when he sees people connecting with nature.
Dave is an entomologist, photographer, graphic designer, app designer and educator. He has worked as a collection manager at the Natural History Museum of Denmark and has experience teaching numerous entomology courses including, the University of Guelph, University of Copenhagen, Ontario Universities Program in Field Biology and Niagara College. Dave is now focused on building DKB Digital Designs, which is a studio dedicated to developing educational software such as Bugdex and BugFinder.
I worked at McMaster University in Hamilton Ontario for 28 years (I retired in January 2018). I had a very interesting job that combined my love for teaching e n t o m o l o g y with my role as Manager of Technical Services in the Department of Biology. That meant I managed a group of a m a z i n g staff members who set up and did the troubleshooting in all of the undergraduate labs in Biology. I also helped researchers with equipment breakdowns and building issues. I was never bored and loved going to work!
On the pedagogical side I taught Insect Taxonomy/Ecology for the Ontario Universities Program in field Biology (OUPFB) at the Queen’s University Biological Station near Elgin, Ontario. I taught this course for 24 years. I also taught insect modules at home and abroad (Honduras in 2009 and Costa Rica in 2010). I also lectured and ran tutorials about insects in several undergraduate courses at McMaster University.
I am a very happy man. I had a great job. I am happily married to a woman who defines pulchritude in everything that she does. I have a great family and true friends that support me, stimulate me, make me laugh and make fun of me. I love listening to music (mostly vinyl) and macro-photography.
Because I have been on this planet for well over 50 years I also know how precious life is and how important it is to enjoy your family and friends now. I’ve been to too many funerals already. My uncle told me often while he was alive that “you won’t believe how fast your life goes by”. He’s right. I feel and act like I’m 26 years old. But a look into the mirror confuses me. The mirror man doesn’t look like me!
Maybe I’m not qualified to offer advice. But here it goes anyway: follow your passion, eat well, drink well and visit those you love often. Try to live your life through balance and compromise. Fight the natural urge to be selfish. Laugh as much as you can!
