All of Darwin's mature African mahogany trees in public places should be chopped down, the family of a man who died when a branch fell on him at a golf course say.

William Brown, 62, died in June 2014 from injuries he sustained after a branch of an African mahogany fell on him while he was playing golf at Darwin's Gardens park Golf Links.

A coronial inquest into his death wrapped up today, and outside the Darwin Magistrates Court his family pleaded for authorities to get rid of similar trees from public areas.

"Especially where there's lots of people and kids," William Brown's daughter, Kerry Collins, said.

"We still should have Bill here with us."

The inquest into Mr Brown's death concluded with coroner Greg Cavanagh noting the tree was extremely dangerous and should have been removed.

"To leave the tree in the position it was in was negligent," Mr Cavanagh said.

"I have little doubt that this death was preventable if there had not been such negligence."

The land the golf club is on is leased to the club by the Darwin City Council.

The inquest heard that the golf club's manager, Roger Dee, and council employees had argued over who was responsible for the maintenance of the tree because it was not outlined clearly in the lease.

The coroner said he would be recommending Darwin City Council change its commercial leases to include specific guidelines about who is responsible for the maintenance and cost of problem trees.

"It is a pity there was quite some argument between the landlord and the lessee about who was responsible to deal with the dangers [of this tree]," Mr Cavanagh said.

"You can expect a recommendation along these lines."

Mahogany trees in Darwin grow larger than in Africa

An arborist giving evidence at the inquest said the African mahogany tree species has killed two people in Darwin and was a "high-risk" tree in tropical climates.

William Sullivan, who has worked with the tree species in both Africa and Darwin, said African mahogany trees grow larger in Darwin because of the tropical climate.

"In its natural environment in Africa, its branches are shorter," Mr Sullivan said.

"Climate has a lot to do with it."

He also told the coroner the branch that fell on Mr Brown likely dropped off because of its size.

"The obvious reason [is] over-extension of its limbs with excess end-weight," he said.

Another arborist, Dr Dean Nicolle, said it was difficult to reduce the risks these trees posed to the public.

"Pruning isn't a viable option to remove the risks ... because of the species characteristics," Mr Nicholle said.

"It has a high likelihood of dropping branches."

Mr Cavanagh will consider the evidence and hand down findings in the coming weeks.
