 Comments
 Tree 8 is an edge tree with a phototropic lean over the adjacent Unit.

 There is evidence of past pruning and regrowth.

 No signs of ground or root plate movement were found at the time of the inspection.

 The risk matrix has been calculated on total tree failure.

 Recommendations

 This is not deemed as a High-risk tree at this time but its suitability for long-term retention beyond 2-
 3 years is questionable and it will need to be reassessed.

 •        Prune branches on dwelling side to reduce general encroachment.

 Re-inspect in 12 months.
