The City of Ballarat will replace trees being currently being cut down on median strips across town.
Residents spotted workers removing trees in Drummond Street and Pleasant Street, among other places.
According to a council spokesperson, the trees will be replaced in the "coming planting season".
"Some trees in Drummond and Pleasant Streets are being removed based on their health and structural integrity," they said in a statement.
"Every so often, the City of Ballarat Parks and Gardens team will need to remove trees that are at the end of their lifespan or are structurally unsound.
"It is part of the regular maintenance process used in the management of an urban forest."
Council has been also assessing and removing ageing and unwell trees around Lake Wendouree since last year.
The council has put aside $500,000 for the Regreening Ballarat Project, which means several trees should be planted for every one lost, and its Urban Forest Action Plan also aims to increase the city's canopy cover to 40 per cent by 2040.
