Maple - a weed. Whether happens such? Last time we told

with you about beautiful and useful maples, about sweet maple juice - it is very probable, beaten just once - another records of gathering birch sap.

Now time for serious conversation about harmful and places a dangerous maple - more precisely, about a tree - the immigrant came (call as want though the illegal migrant - it seems, before the collapse of the USSR it was even entered in quarantine lists on an equal basis with an ambrosia as the most dangerous wrecker!) - about a maple - “turncoat“, that “every family has its black sheep“ which harm repeatedly moved scanty advantage …

… About maple yasenelistny which call also American (that brings which - what confusion as many very valuable maples it is from North America) - Acer negundo.

Who could think in those not really far times when the yasenelistny maple was brought to the Old World (approximately the second half of the XVII century) that graceful at early age, but quickly growing and “matereyushchy“ being is aggressive and will even quickly force out from streets of the cities of northern Europe many tree species, usual for them?

Yes, the yasenelistny maple can sustain a lot of things - is unpretentious, normally transfers smoke of the atmosphere and therefore the section of biology under the name “Industrial Botany“ recommended it for gardening of the industrial centers of the West. After it - it is casual or not - got also at us …

Yes, he quickly grows up, reaching a maturity in 10 years - well, in 15 if living conditions absolutely nasty and if the person so dirtied the environment surrounding them that began to call ecology bad. Though ecology - it, as mathematics and geography, chemistry and physics with cybernetics - first of all science that is, the ecology as science cannot be bad or good. The human factor whether you know … the Maple yasenelistny captivated

not only Europe - it already and in Kazakhstan, in Central Asia feels at home. On the small streets irrigated by aryka under the scorching star beams by the name of the Sun, in desert and semidesertic areas where, apparently, the normal tree is not capable to grow (actually, rare trees - but habitual, adapted long since for the climate, as a rule, undersized grow and there), this “newcomer from the West“ looks more - less decoratively and, it seems, not really disturbs locals. There lives almost like a person - from fifty to hundred years, not the couple to the famous long-livers, baobabs and oaks …

But judge for yourself - a maple yasenelistny, appears, having fragile and not valuable (yes what there, just parshivenky) wood, easily gives in to flaws - strange that fragility of its branches did not become still “a parable in yazyets“. And what will be your neigbour or relative to feel how on the head to it, having loudly burst, the weighty bludgeon with leaves, atypical for a maple, falls! At this moment, believe, the type of a zhilkovaniye and a rassechyonnost of a sheet plate is not interesting at all! By the way, its branches fall and in windless weather - break just from own weight, from age, from mood, eventually …

But root offsprings differ in surprising impudence and endurance - safes literally crack asphalt as “bear-hunter“. On the sidewalk, on the carriageway. And if, having stumbled, the pedestrian has chance to keep standing, then on camber with the roadside the car easily will jump up - and if speed “incidentally“ exceeded it maximum permissible, then, at least, easy cherepno - the brain trauma is provided to the driver!

If you look in the old press, then can find phrases like “ … force to refuse application of this maple in gardening of the cities and large industrial centers in recent years “. But, alas, late, old man! The Yasenelistny maple ceased to be landed long ago (unless in the old manner, to ignorance or congenital denseness the rare local head of “Zelentrest“ continues to spread), and it already and it is not necessary to raise! He on himself remarkably accustomed to our cities, having captivated them to a limit. And, it is possible when you feel an unpleasant smell from the branches broken near the house - actually you will get acquainted with its American aroma...

It seems, even goats do not eat leaves of “the green newcomer“.

And still spring blossoming of a maple yasenelistny (unlike other maples which were less noticed in this sin) has pernicious effect on health - our, on health of our children. Abundance of pollen, just the pollen clouds almost imperceptible to a third-party look, envelop people in the cities and villages, causing more or less serious allergic reactions which in some cases come to an end sadly - development of bronchial asthma.

And here the harmful polynnolistny ambrosia behaves in the same way aggressively, boleznetvorno … By the way, the one-year grassy “girlfriend of the friend“ is from America too. There to it somehow did not allow to clear up, other live organisms, evolution - piece serious put in a tight situation.

Generally, it is not that maple about which our dear Nikolay Vasilyevich Gogol wrote in unforgettable “May night“: “Majestically and gloomy the maple wood …“

Or that blackened? Having strange magic? “Wizard with a shadowy past“?.

Because it is difficult to present that the plant (not the person, not army) so aggressively occupied a set of the countries - and for a period, insignificant to historical measures, …

Oh, and we will cry at ease with these American “green newcomers“!
