Members of the public are reminded to take care around gum trees in these hot, dry conditions, due to the risk of falling branches.
On Saturday, Bendigo State Emergency Service volunteers attended Crusoe Road where a large gum tree branch had dropped and completely blocked the road.
It also caused damage to power lines.
Bendigo SES deputy controller Natalie Stanway said tree-related jobs formed the bulk of the unit's work, up to 70 per cent.
In summer, Ms Stanway said, these jobs became more common as trees dropped limbs to preserve themselves in the hot, dry conditions.

She said this occurred without notice and while it was more likely to happen on windy days, due to the flexing of branches, it could happen at anytime.
Bendigo Tree Service arborist Ian Costello said all trees dropped branches at times, shedding lower limbs as they grew.
However, he noted smooth-barked gums - such as the lemon-scented gum, nicknamed the Widow Maker - were more prone.
Like Ms Stanway, he said the dropping of limbs came without warning and was something even experts could not predict in many instances.
"The tree system and surrounding environment is too complex to pinpoint the imminent advent of a failure in so many cases," Mr Costello said.
Ms Stanway advised that people not park under trees if possible in extended periods of heat.
People should reconsider picnicking or camping under such trees.
"Unfortunately, we have attended a number of jobs were people have been injured or killed," Ms Stanway said.
Trees affected by fire were often particularly dangerous, she said, even when they might not look unsafe.
"The risk to people in [bushfire-affected] areas is considerable," Ms Stanway said.
She urged people to take the advice of emergency services when moving in such areas.
Mr Costello encouraged people to think about the potential risks, but also consider the benefits of the trees.
"While considering the danger of being under a tree, the other side of it is how lovely it is to have the shade and the green of trees around us."
