Transition of Weather
In this morning, I prayed that the weather conditions would be bright and fine within Keppel Club golf course. This could enable me to have meetings with two ISA Certified Arborists at different time intervals to carry out the health and safety conditions of 7 tall Albizia trees. Few hours later, the sky turned out to be dark with heavy grey clouds. But walking by faith, I believed in God that it would not rain so soon. Gradually, the darkness has “transformed” into bright and fine day! It happened as what I had thought. Praise the Lord! Always give thanks to Him! Amen!
Conducting the arboriculture inspection with two arborists, the findings are such good and knowledgeable to me. I have learnt a lot from them. In my heart, I am really very passionate to take up a recognized International Society of Arboriculture course so that I can become a certified arborist. This can be done at NParks CUGE. Will seek, ask and hear from God first for this plan. Because His plan is better than my plan, this will help guide me to walk in the right path. This would please God! Amen!
Arboriculture
For Ronald’s own reference / notes about Arboriculture:
Albizzas are dangerous trees as they are generally very soft wood. At this big size, they are self-disintegrating = they will snap and cause failure anytime. ON the other hand, Albizzias are always good because they are vigorous. But it’s the structural stability that is always the concern.
The health of the trees can be indicated by
1) live crown ratio
2) leaf size
3) leaf colour
4) leaf density
5) canopy dieback
The arborists generally never recommend Albizzias to be grown near target areas. Targets are defined as people, structures (buildings), places with traffic movement, etc.
If you see the Albizzias’ main trunks which have hollow holes (almost or more than 50%), it is mostly predictable to fall down anytime. It is dangerous.
Normally, the certified arborists will encompass both
health and
structure of the trees when they conduct our
Visual Tree Assessment Report.
If the health condition of trees is good, the tree is structurally unsound, the arborists will normally recommend for removal in the interest of the people’s safety here. [Vice-versa]: - If the health condition of tree is poor but the tree structure is ok, the arborists can boost their health by giving them treatment like element injection, soil restoration works, etc.
The pruning of Albizzias should be recommended to be carried out each half-year (every 6 months).
Question: How will the workers access up the tree at a very tall height?
Answer: They use safety harness & ropes to access high up on the tree. They should wear in full PPE (Personal Protective Equipment) such as safety helmets, boots, goggles, gloves, etc for safety reasons.
