In the 20s of April, Lukashenko traditionally visits the areas affected by the Chornobyl nuclear accident.
"The revival of these lands is always given special attention and, given that this time the president’s trip coincided with the community work day in the country, Alexander Lukashenko decided to take part in the work on the territory of the Pripyatsky National Park," the agency said.
In order to resume forest mass on an area of one and a half hectares, several thousand pine seedlings with a closed root system will be planted in the park.
Earlier, Lukashenko has labelled fears about Covid-19 a "psychosis", and warned that a shutdown would harm the economy. In defiance of medical advice, he has cited drinking vodka and regular trips to the sauna as ways to ward off the virus.
Belarus has not closed it borders. There have been no strict lockdown measures, and schools reopened last Monday following a three-week holiday.
There have been 8,773 confirmed coronavirus infections in Belarus, and 67 reported deaths, according to data from Johns Hopkins University.
