Georgy Fedorovich Morozov (Russian: Гео́ргий Фёдорович Моро́зов; 7 January 1867 – 9 May 1920) was a Russian forester and biologist who introduced the first ecological ideas to classify forest types. He introduced ideas of "the forest as a plant society", which he developed into the definition of the forest as a complex biogeocenotic, geographic and historical phenomenon that was made up of non-living and living components.
