Acer platanoides + Acer pseudoplatanus - leaves (+ Polypodium vulgare + Geranium robertianum) (4820' N 1503' E)

Description:

2011-10-23 Lower Austria, district Melk - Ysperklamm (740 msm Quadrant 7656/3).German name: Spitz-Ahorn + Berg-AhornUsually - at this altitude, in ravine forests like this one - Acer pseudoplatanus should dominate, here however Acer platanoides is more common than the former: the latter needs warmer climate and usually only would dominate at lower altitudes.The reason for this might be that the valley is orientated to the south, and thus provides for a warmer micro-climate fitting for Acer platanoides.
