TALK TITLE
Writing Transplant Specifications
ABSTRACT
Being involved with saving and moving large trees is often very satisfying work. Arborists and landscapers often perform the work associated with transplanting large trees. Suitable specifications are required to successfully move large trees. Consulting arborists who understand tree anatomy are often best suited to write these specifications. However, to do this, the consulting arborist needs knowledge and skills that may not have been garnered through their education and training thus far. These include:
some of the advantages and disadvantages of transplanting large trees,
an understanding of the different methods that can be used to transplant trees, including their pros and cons,
the key metrics used in determining the specifications,
root plate (root ball) ratios for the various methods,
some techniques for developing quick mass calculations of the above and below-ground portion of the tree,
basic engineering issues associated with transplanting,
problems and pitfalls that are commonly associated with transplanting big trees,
the key steps involved and the transplant processes, and
understanding aftercare and how this is similar to and different from the care of trees left in situ.
While this presentation will not make you a transplant expert, it will alert you to gaps and weaknesses in your skills and knowledge and confirm what you already know and understand. Equally as importantly, the presentation will assist you in better interacting with those specialists you need to interact with when preparing transplant specifications.
