The conservation of plant gene resources in the „zapovedniks" of the USSR [PDF]
, 1986 The conservation of plant gene resources means the maintenance of all diversity of flora and vegetation. Rare species are the first to be threatened with extinction. They have got limited areas and a rather scarce abundance.
