Stop the "American"...

One of the emails:

This maple tree, so long ago in Russia and suddenly now began to "capture it"?!

Yes, just imperceptibly, when gradually. And when I didn't see the tracts for 20 years (I was away), and then I came... Not just a settlement-a fire! If you don't believe me, I invite you to visit the forest - steppe gullies of the Lipetsk region, Danilovskaya in the Volgograd region, Galichya Gora and many other places. By the way, a new forum congress could be held in Danilovskaya Balka! A chic place, with chalk outcrops of "mountain appearance", once beautiful oak forests (now completely captured by the "American"), a small river below, meadows (also "shot through" with maple)... All biotopes and lots of interesting insects! Not yet...

This maple is called ash-leaved in Russian.

You need to be more precise in your expressions if you want to look like a professional biologist.

You seem more attracted to anti-American hysteria.

Take it easy, please.

The transportation of live insects across the borders of states for the purpose of releasing them in another country is probably illegal.

Don't call for it.

That's it... Please note: Aceg negundo. I.e. a species from the same genus as our maples, and not from any purely American taxonomic group. Accordingly, the risk of its natural enemies switching to our maple species is very high.

Alas, amara, the Russian name is all right. Well, first of all, there are no generally accepted Russian names (since there is no Russian code). So some botanists refer to Russian names as well as entomologists And secondly, in the Flora of Eastern Europe (volume 9) Acer negundo just Maple American

And why not try processing the cut with arboricides? Expensive?

Here is from In-eta, from the site http://belfm.ru/:

EVERYONE TO FIGHT THE AMERICAN MAPLE TREE!

Forest management specialists of the Belgorod region warn that the spread of American maple leaves is dangerous for local ecosystems and recommend not only to abandon its use in landscaping, but also to actively work to destroy this weed.

The ash-leaved maple imported from North America creates several problems at once. First, it becomes brittle with age and is a real threat to people and buildings in its vicinity in strong winds. At the same time, the tree is short-lived: its top begins to die off in 25-30 years. In addition, old American maples do not purify the air, their roots destroy asphalt, and pollen causes allergies. And for forestry and agricultural workers, the real disaster is that the ash-leaved maple becomes the breeding base for the white American butterfly. Voracious insect caterpillars cause damage to trees and shrubs.
At the same time, like any weed, American maple is frost-resistant, undemanding to the soil. It tolerates urban conditions well and quickly repairs damaged parts. Despite the fact that municipal services of cities and districts of the region struggle with such plantings, the plant is able to produce abundant growth even after cutting, and reproduce with unripe seeds. As a result, thickets may appear even within the city limits.
You can only deal with American maple in special ways – in particular, treat it with special chemical compounds. Experts recommend such products as herbicides of continuous action "Hurricane", "Tornado", arboricides.

Wild Yuri Comment:

The Belgorod Region is launching a counteraction, and it is supported by forest management specialists. It seems that Lipetsk also joined it. Just the other day I saw maples being felled in Kamenny Log. But that won't stop him. From the cut - a mighty growth and rapid restoration of the tree. We need to bring leaf-eaters...

In the same article (see the link above), I learned something new: it turns out that this maple tree is devoured by an American white butterfly, and it even serves as its breeding ground! (Funny thing is, I've never seen a maple leaf eaten before!). So it's not that simple. The article about the introduction of ambrosia leaf beetle (link even higher) also says the same thing. Nevertheless, new attempts at biological control of the maple tree are needed. The results are always very different, but some can be radically successful. You need to experiment (in the aviary), act (in the wild, after successful experiments in the aviary, and - the enemy will not pass, the victory will be ours!

And why not try processing the cut with arboricides? Expensive?

I already wrote above. Our expanses will not have enough substance or hands.

I don't want to look like one. I am one. And, by the way, I sometimes edit Wikipedia.
This maple tree has two names: ash-leaved and American. Another example: lemongrass and buckthorn. Which is more scientific? Still Latin, I think.

Danilovskaya balka (Volgograd region). Pale green spots - blitzkrieg American maple (20-25 years ago it was not there at all).
