Forest introduction: There are more than a thousand kinds of plants in the primitive forest, including more than 70 kinds of shrubs and more than 20 kinds of forest trees. Many kinds of rare plants are considered to be iconic organisms in the history of natural evolution. One of the ancient dor trees, "Jacquilon", once recorded the historical event in 1409 when the King of Poland, Wlaslav Jaquilon, led his troops to fight against the Teutonic Knights in order to satisfy their hunger with hunting.
