Only the nominees of Portugal, Spain, and Russia finished the competition ahead of Zengővárkony's survivor, the sweet chestnut in the European Year Tree competition in 2018. This year the trees of 13 countries competed with each other, collecting altogether more than 200,000 votes during the online voting period in February. The Portugese "whistle tree", that is named so because of the numerous birds on its branches, is considered to be the world's largest cork oak in the Guinness Book of Records. Hungary was represented by the Zengővárkony's survivor, the sweet chestnut, which became the Hungarian Tree of the Year with 4088 votes in November 2017.
