Passive gene conservation of beech populations in situ has taken the form of nature reserves. The<br />

gene conservation units are consi<strong>de</strong>red an active way of gene conservation and reproduction. These<br />

units are groups of stands with a minimum area of 100 ha. Here natural regeneration of target species<br />

is obligatory. If natural regeneration is not successful, it is possible to use a reproductive material<br />

coming from these units for their artificial regeneration. Gui<strong>de</strong>lines for the management of individual<br />

gene conservation units are elaborated by the FGMRI Strnady (Novotný, Frýdl, Čáp 2008).
