Ochrona zasobów genowych a sukcesja roślinności w rezerwatach i parkach narodowych
Abstract
An unexpected and uncontrollable succession of vegetation
in national parks and reserves causes the impoverishment
of a gene pool of plants. This process has been observed
mainly in seminatural communities and distorted natural
phytocoenoses. A programme of practical endeavours should
be based on a conscious management of the succession. It
has to take into account the entire caryologic, ecological
and sociologic variability of each species as well as to lean
on a thorough study of a degree of naturalness and dynamics
of the communities in which the species exist.
