Tree Of Heaven Family

2011-09-04 Lower Austria, district Wien Umgebung (225 msm Quadrant 7965/1).German names: Berg-Ahorn + Hoch-GtterbaumForest exploited in 'Niederwaldwirtschaft' (short rotation coppice - for that see remarks here); however, with switching from traditional methods (that is, leaving the cut forest alone, which will grow new shoots from stumps and roots) to a much less favourable in terms of biodiversity: saplings are planted (here Acer pseudoplatanus), and unwanted growth of other trees is cut down.Here you can see a stump (of Quercus pubescens, would be my guess) which is dead already, and surrounding the acorn saplings you can see plenty of (mostly) Ailanthus altissima which have been cut recently.

Ailanthus altissima, syn.: Ailanthus glandulosaTree of Heaven, Chinese sumac, Stinking sumac, DE GtterbaumSlo.:veliki pajesen, primorska smrdljivkaDat.: Aug. 04. 2013Lat.: 46.36171 Long.: 13.70444Code: Bot_738/2013_IMG3784Habitat: Overgrown former garden and grassland; dominant species Ailanthus altissima, Fraxinus ornus, Corylus avellana; next to an abandoned farmhouse; flat terrain, calcareous ground; relatively dry and warm place; average precipitation ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 600 m (2.000 feet), alpine phytogeographical region. Substratum: stony, shallow soil.Place: Lower Trenta valley, between villages Soa and Trenta, near abandoned homestead 'Koc', Trenta 3, East Julian Alps, Posoje, Slovenia ECComment: Growing in dense 'monoculture' thickets. This is probably the invasive plant, which most aggressively changes the cultural landscape in the upper Soa river region today. Now abandoned, but in past centuries man-made, grassland, modes stony fields and gardens around abandoned farmhouses as well as road sides and river banks and all other semi-ruderal ground are under its attack. It doesnt spreads only by seeds (a big tree can produce 300.000 winged, wind dispersed, seeds) but also with fast growing underground root sprouts. Therefore it conquers new land advancing in a tight FWW 'front line'. At the same time the tree prevents growth of other competing plants making the ground poisonous for them. It can overgrow cultural land together with abandoned farmhouses (see Fig. 9) in a decade. It's almost impossible to control it. Cutting it only encourages a plethora of root sprouts. Pulling it doesn't help since each small fragment of the roots left results in new sprouts. Several fungal pathogens are under investigation as possible control agent. In mid eighteen century gardeners, not knowing what they were doing, brought it from China to Europe.Ref.:(1) A. Martini et all., Mala Flora Slovenije, Tehnina Zaloba Slovenije (2007), p 339.

2008.06.23: Austria, Vienna XXII. district, 152 m AMSL, heath (Lobau Heisslnde) (with Melica transsilvanica): 'ringed'.'Ringing' was developped as a strategy against some invasive species, see also Robinia pseudoacacia; if applied properly it should kill off the tree. Here in this case it's obviously not working too well: most specimens of A. altissima ringed in this habitat died off above the ringed spot and supported new growth from the stem below, and from roots: which happens when the ringing method is not applied correctly.Flowering in june (july).Common, invasive (introduced in Austria in 1751).German name: Hoch-Gtterbaum.For ringing method cf. AGES where they say that ringing should also work for this species, if applied correctly.

2009.08.27 Austria, Vienna III. district (growing IN a railway station where its roots must have found some earth behind those panels, 170 m AMSL).Trees are bearing fruit at this time of year, however this one isn't fruiting yet.Ailanthus altissima may grow out of the tiniest gaps, even when (as in cases like this one) it is even difficult to imagine where the tree has set roots.Very common, invasive.German name: Hoch-Gtterbaum
