In this connection in ripe and pre-ripe pine forests stands Scots pine underwood is presented only in narrow age-old ranges. Cenotical condition for the maintainance of Scots pine underwood is most favorable in poor edatopes, in particular in poor subir's. There the second storey of forests stands is absents, and crown closure of third storey is low, an undergrowth is very liquid, bryophytess and bushes prevail in a forest vegetal cover, and the particle of grassy plants is low. In more rich edatopes, in particular already in poor sugrud's, conditions for the saved of underwood under the forests stands crown closure is unfavorable, as there is already the second storey of forests stands, which together with the third storey considerably promotes crown closures. In addition, an undergrowth is more thick, and bushes and grassy plants prevail in a forest vegetal cover, a blackberry grows. In rich sugrud's in connection with the difficult vertical structure of forests stands, their high crown closures and dominations of blackberry in a forest vegetal cover natural renewal of Scots pine is very unsatisfactorily.
