People visiting South Barrule plantation are being urged to stay out of restricted areas.
The government's warning follows an incident this week where someone entered a high-risk zone to film heavy machinery doing harvesting work.
There were also cases of the public approaching machinery during works on dirt roads.
In a social media post, the government is stressing that even briefly stepping into prohibited spaces poses a risk of serious injury or death.
Tree harvesting operations at the southern plantation are expected to continue for several months.
