As noted, the list includes: 5 elm trees over 100 years old growing in the Chimboy district of the Republic of Karakalpakstan; a 200-year-old mulberry tree in the city of Jizzakh, Jizzakh region; a 250−300-year-old mulberry tree in the city of Kattaqo'rg'on, Samarkand region; a 450-year-old plane tree in Narpay district and a 1000-year-old plane tree in Payariq district.

Previously, the list included 8 tree species located in various districts of Jizzakh, Samarkand, Tashkent, Surkhandarya, and Kashkadarya regions. With the addition of new trees, Uzbekistan became the first Central Asian country and the third CIS country (after Russia and Azerbaijan) to include its natural heritage sites in this international registry.

For reference: the List of Monumental Trees is an international registry that includes trees of historical, cultural, or natural significance.

Such trees are generally distinguished by their impressive size, ancient age, unusual shape, or cultural value. The purpose of the list is to raise awareness of these natural resources and contribute to their preservation.
