Andrei Krasnov

Andrei Nikolaevich Krasnov (Андрея Николаевич Краснов; 27 October 1862 – 19 December 1914) was a Russian botanist who explored the plants of Turkestan, Altai, Nizhny Novgorod, Tian Shan and the Caucasus regions.

He was also involved in the introduction of plant species, making use of Australian eucalyptus trees to drain swamps.

Krasnov had already begun to examine patterns in the distribution of plants within the Russian steppe in 1888.

In 1894 he defended his doctoral dissertation on the grassy steppe regions at Moscow University.

[2][3][4] Krasnov used the representation F = f1 + f2 + f3 to separate the flora of the Steppe with F being the plants now found and classifying them into f1 - the original Palearctic flora, f2 - old species that have undergone change to current conditions and f3 being new species that have come into the region.
