Hundreds of century-old inner-Melbourne trees will be re-inspected after a university professor was fatally crushed by an elm planted in 1913.
University of Melbourne academic Allison Milner, 36, has been remembered for leading research on suicide prevention following her death in the freak accident at Parkville on Monday.
The mother of two died in hospital after the 106-year-old elm tree fell on her in Royal Parade about 8.30am.
The tree was inspected and declared safe a month before and the City of Melbourne is now rushing to audit hundreds of inner-city trees around popular footpaths and parks.
Fifty-eight ageing trees along Royal Parade were re-inspected on Monday and another 380 will be checked this week.
The council says any trees posing a risk will be removed immediately, adding to 800 trees already taken out each year.
"I have lost a dear colleague ... by this f***ing tree," Prof Milner's colleague, Anne Kavanagh, tweeted on Monday.
Another coworker paid tribute to Professor Milner as "an extraordinary scholar, mentor, colleague, friend and mum" who led Australia's largest study about doctor suicides.
"Allison Milner will be so deeply missed by all who knew her," fellow University of Melbourne academic Marie Bismark tweeted.
In a statement, the university said Prof Milner's death had come as a great shock and an immense loss to their community.
"Her research spanned the fields of suicide prevention, work, gender and disability," the university's Terry Nolan said.
"Most importantly she was a wonderful colleague and friend. She was humble, generous and caring."
Law firm Maurice Blackburn called for an urgent audit of ageing trees on public lands, particularly those along footpaths.
Prof Milner's death comes days after Melbourne mum Angie Suryadi died when a tree crashed onto her family's car amid strong winds northwest of Melbourne.
Her two young sons and husband, Arnold Adiatiasvara, were also injured in Friday's accident.
