Talks at Manchester University will cover the built environment, urban design and the strategic management of tree stocks, and biological control of tree-decay fungi.
Speakers will include Professor Francis Schwarze from Switzerland, Giorgio Catena from Italy, Philip Van Wassenaer from Canada and David Nowak from the USA.
A representative said Manchester was the "green venue choice" for this year's event and encouraged delegates to travel by public transport.
Delegates will learn the latest on simple solutions to stimulate root vigour, thermal imaging and tree assessment technologies, he said.
"In association with the National Association of Tree Officers the conference focuses on challenges facing tree officers: professional status, budgets, strategy and management."
Highlights will include an overview of current systems including i-tree software from the US Forest Service and a field day to Tatton Park arboretum.
"The ever present dilemma of tree safety verses benefits will be addressed along with research results into the strength of branch forks within trees.
The conference costs from £165 and runs from 12 to 15 September. Visit or contact 01242 522152.
