Tree Matters

 The Industry Magazine Publication of the New Zealand Arboricultural Association (NZ Arb)


Tree Matters is the only publication where arboricultural professionals can read about the very latest issues in the management and maintenance of trees in both theory and practice – and in a local New Zealand context. 
Issues that are fundamental to the role of arborists like planting, pruning, structural support, diagnosis and treatment of diseases, insects, or disorders, lightning protection, and tree removal are now vitally relevant and highly topical for professionals working in the broader arboricultural industries.
Other information covered includes tree climbing (using ropes, harnesses, and other climbing equipment), health and safety, assessment, legal requirements, and training.
