"If Auckland Council insists on protecting this tree, then they also need to take responsibility and pay the costs if any property and persons are damaged or injured," said Mrs Wenley.
Andrew McAlpine of Remuera intends to make a similar plea today.
A wellingtonia, or sequoia, in his "smallish" front yard has grown to 20m and he said yesterday he was told the species could grow to 60m.
"To be honest, I like the tree but it's like having an elephant for a pet."
Auckland Council arborists took into account a tree's life expectancy but not the risk of its falling when they assessed the 2800 trees nominated.
But Tree Council field officer Hueline Massey said arborists would not recommend a tree for the schedule if they thought it was in danger of falling over in the near future.
