Arboriculture II BHT208
DescriptionBuild on your existing aboriculture knowledge! Develops your ability to manage trees beyond Arboriculture I, in order to minimize potential long term tree problems. Learn about better tree selection, strengthening and improving health of existing trees, and techniques used to better remove trees and stumps that must be removed.

Each lesson culminates in an assignment which is submitted to the school, marked by the school\'s tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.Aims
- Explain how to plant a specified advanced-sized tree on a specific site.
- Explain tree injection, including the technique and applications.
- Identify situations where trees require strengthening operations to be carried out.
- Compare different ways to control roots which invade underground pipes.
- Calculate the cost of removing a specified tree.
- Determine appropriate tree species suited to a specific site visited and analysed.
- Devise a method for removing a tree, including tree felling and stump removal.
- Analyse specimens of mature trees, from different genera, to detect any patterns in problems occurring in those trees.
- Develop criteria for the establishment of a tree plantation on a specific site which addresses; site restrictions, cost and function.
