2010-10-10 Hungary, Nyugat-Dunntl - Western Transdanubia, county Vas (840 m AMSL).This place lies a short distance below rott-k - Geschriebenstein peak; the foreground is a more or less natural spruce-beech-fir forest - with Fagus sylvatica and spruce shown in the photo -, while in the background you can see spruce monoculture - Picea abies - older than the (now dismantled) Iron Curtain (trees at least 60-80 years old, many a hundred or more).Even though the Austrian border is not far you can only see Hungarian territory here.So while the forests on the Hungarian side of this mountain are more natural by magnitudes than those on the Austrian side there are still a few monocultures there.
