Description
Summary:Climatological factors determining the natural northern boundary in Europe of oak ( L.) were investigated. The natural northern boundary of oak corresponds in detail to the curve at which the growing season, beginning at +5°C in spring and ending at +10°C in autumn, is of a certain constant length. The northern boundaries for more oceanic plants can be explained by prolonged autumn activity. This is obviously the general explanation or the concept of oceanity. Oak spread markedly in Finland in the summers during 1961â1975, which on an average were as warm but much dried than those during 1931â1960. The importance of humidity for oak was discussed.Quercus robur
