Arboriculture II (intermediate) 100 Hours Certificate Course

Intermediate Arboriculture course online. Build on your existing arboriculture knowledge! This follow on course delivered via distance learning and home study, builds on what you learned in Arboriculture I, but goes much deeper into planting and tree care.

It also develops your ability to treat trees in order to minimise potential long term tree problems, tolerance of different tree varieties to specific environmental conditions, plus bracing, felling and stump removal skills.

You will even learn how to establish a tree plantation including important knowledge of planning and producing scale drawings, plus designing wind breaks into the project for tree protection.

Once you have finished this informative programme developed over many years by experts in tree health management, why not improve your skills even further with Trees for Rehabilitation and/or Deciduous Trees, covering trees such as: Maple, Birch, Ash, Oak, Prunus and other varieties?
