The Authority is sharing the message on social media, giving the term "tree hugger" a whole new meaning.
Officials say it can help people feeling socially detached while also getting out in nature.
"In this unpleasant corona period we recommend to people around the world to go out to nature, take a deep breath, hug a tree, express your love and get love," Orit Steinfeld, the authority's marketing director, said in an interview with Reuters.
Israel's campaign follows a similar one launched in Iceland a few months ago.
