Wow, just when I thought the PTCA (Professional Tree Care Association) annual seminar was the bomb, the following field day was just as great. While the seminar was an indoor event focusing on a variety of topics presented by outstanding industry professionals and educators, the field day was spent outdoor at beautiful Balboa park in San Diego.
The day consisted of a number of workshops organized into several different tracks that allowed participants to choose from a palette of presentations that provided something for everybody. Tree climbers and field workers loved the tree climbing workshop and training by Mr. Martin Morales. His workshop included climbing and positioning for safe work in trees, also taught about knots, ropes and equipment inspection, while providing new tips and tricks. I am way to old for climbing, but enjoyed watching guys in the trees, had an opportunity to meet Martin during an incredible lunch (carne asada). We were looking at a rigging holding a tree log, he immediately pointed out flaws and worn equipment, I would never have noticed. Fortunately we have educated tree climbers who understand the importance of proper equipment, training and safety. Another track included Tree Risk Assessment best management practices (BMP’s) workshop taught by Mr. Ron Matranga and Dr. R. Bruce Allison. Since I consult and provide tree risk assessment as part of my practice, it was a great opportunity to learn about best management practices involved with the new TRAQ (tree risk assessment qualified) versus the previous TRACE (tree risk assessment certification exam) methodology. Dr. Allison demonstrated new sonic tomography techniques for non-destructive testing of the interior of tree trunks, new cutting edge technology that is already an advancement from just two years ago. Using probes and determining the time for sound waves to travel through tree trunks and how the sound wave moves at different velocities around interior trunk decay will assist arborists to use in advanced tree risk assessment. As Dr. Allison noted, hopefully in the next few years, the cost will come down and we will have a pocket sized device and an app to use to help us understand what is happening with interior tree decay.
We all know about new invasive insects and diseases affecting our trees, new invasive species are being detected at a rate on one every 60 days, Dr. John Kabashiima provided the sobering statistic it is now one every 45 days! The gold spotted oak borer has decimated tens of thousands of Coast Live Oak and Black Oaks throughout California.
This pest has been spread throughout the state, particularly San Diego county by people using the dead wood for fire wood, transporting it in their vehicles where they unwitting spread the insect throughout the county. Don’t move infected wood!
For pest control advisors and applicators, there was a pesticide application for trees demonstration and a safety workshop and tree identification workshop and quiz available to test your knowledge. Field guys loved the chainsaw sharpening and troubleshooting workshop presented by Mr. Paul Lasiter and Mr. Joe Garcia. Another great aspect for everyone was presentation of many workshops in Spanish and English, a very inclusive aspect that helped all of us enjoy the day.
I learned a great deal of new information I never would have even considered without this great field day presentation. Have you ever considered how heavy a downed tree trunk is? Well, there was a workshop on how to calculate the wood weight of felled trees, presented by Mr. Harvey Pedersen. Crane operators have to have a reasonable idea of how much a log or portion of a tree trunk weighs in order to safely lift it. Mr. Pederson presented wood weight calculations of various types of trees and an amazingly accurate method for estimating the weight of a log, which was then lifted by the crane which provided the true weight to compare against our estimated weights. How cool is that!
Just want to thank all of those involved in the PTCA Seminar and Field Day for a truly memorable event, a special thanks to our friend Dave Shaw
who once again served as the master of ceremony and kept us all entertained. Keep up the great work, looking forward to next years seminar and field day.
