I think the easiest way to spot an infected tree is to look for new branches growing near the bottom of the tree below the first main branches.

That only happens after the trees been infected for a few years

I was going after the spotted lantern flies when I came across a beetle I thought was an emerald ash borer. I had to go online to see what it was. Sure enough I caught my first ash borer. I killed it even though all our Ash trees are dead or dying in my area. Thanks for the info.

Andrew, given that EABs lay their eggs in the crevices of Ash bark, this means that the trunk of an Ash tree must be of a certain age/diameter to develop a texture of use to EABs. I think Ash trees could be kept free of EABs if they were maintained on a coppice cycle, i.e. being cut to the base during dormancy every handful of years. Ash is known to respond exceptionally well to coppice and pollard treatment. Ash wood is traditionally used for broom handles, rake handles and other applications which require wood that is strong for its weight. These applications lend itself to a coppice cycle of 5-7 years, which I think would prevent its bark from ever reaching the mature texture preferred by ash borers. I haven’t had the chance to coppice any Ash trees yet but will hopefully do it this winter. It is an ancient practice. Thoughts?

coppicing and pollarding are very useful for wood, but I don't think that would be a good solution for forest ecosystems, the timber industry, or urban decorative trees? To me, these seem like the uses where ash *specifically* is more important. Though I've heard that black ash might be having some problems too, and losing their root systems is apparently going to be a HUGE problem because of how they filter ground water? That would be a reason to pollard/coppice ash around waterways.

I have made a grave mistake. I had several ash trees on my property, but they were covered by cedars. I had the cedars removed, and I guess that allowed for this beetle to flourish. Now I have 20+ dead trees. I am angry.

Hi Andrew, great presentation on theEmerald Ash Borer! I learned so much. But all adult frogs, or at least all that I know of, are carnivorous as adults only and therefor would not eat ash leaves as the video states. Yes, as larval "tadpoles", most frogs are herbivorous. I assume you mean that tadpoles of frogs feed on ash leaves that fall into their natal ponds, but not that adult frogs munch on ash leaves. It might be best to correct this in the video. Keep up the great work. You have very compelling videos!

Thanks a lot for pointing that out, Thomas! Great point, I should have mentioned they were useful to the tadpoles but not the adults.

Thanks Andrew! I hope Ash makes a comeback! It's a beautiful tree with and has extremely usefull wood.

Great video man. Really informative!

Some of my ash trees are starting to come back nearly all the young ones that were killed when young. I imagine the bugs killed all ash trees then they died out due to lack of resources in certain areas and the ash can come back

Great vid, subbed. Our Ash in the UK are dying too. A different organism though. I have some info on it if interested. Amazing tree the ash. Thanks for the info 👍🏻

Do tell! I'm interested

I've got 3 infected trees on my property and have lost the most mature one because of these pests. It's so nasty looking at them. I don't find them pretty at all 🤢. The other 2 have pesticides treatment. There are actually quite a few videos out about the science of EAB on the internet these days.

Any knowledge of presettlements natural forests where Ash trees now predominate? I think feel intuit that long range out of balance state as well as pollution factors combined with foreign pests is indicated in the ash borer plague. Other invasive species problems insects nutrient depletions that would assist the whole pictur ( condensation evaporations original natural waterways springs etc ) and manmade chemical soil air contaminations known or signs of also essential to discern ecosystem solutions. Ie anyone applying wisdom that was realized to save black forest of germany from acid rains? applyed trunk nutrient concentrates Also what are diatomaceous, and other natural elements against Ash Borers? There is a better way to address than allowing further chemical contaminats that will effect other species ... Thank you for your thoulrough well presented topics.

I've got all of the signs and I am too late to save my tree😢😢

Could you explain the evolved natural resistance mechanisms of the Manchurian and Chinese Ash trees to the EAB? Excellent video, thank you for sharing!

Hey Matt! From what I understand, there are many genes in Asian Ash species that confer a degree of resistance to the insect. I can't quite find what these genes are or what exactly they do, but I know they are responsible for producing chemicals or compounds that are toxic to Emerald Ash Borer larvae. I think Asian Ash trees may also have a different composition of tannins and lignins in their bark which may make it more difficult for borers to eat through. Since North American Ash trees evolved with no borer, they lack these genes. There is a good amount of research being done to identify these genes in Asian Ash trees. Penn State is also finding a very small percentage of North American Ash trees that are resistant to the insect to some degree, and are working to find the mechanism behind this resistance.

@@iC0NB0Y I couldn't have asked for a more informative response. Do you know how efficacious a genetically modified solution might be in improving the resistance of American Ash trees? Is the European resistance genes compatible with the American ash genome? Very exciting work, do you happen to know whether there is a scientific consensus on a quantification of the number of ash trees that have already been decimated by the EAB? Thank you for making your work and knowledge accessible to the public and you do a phenomenal job communicating science to the public!

@@iC0NB0Y I seriously wondered this same thing and found it weird that piece of information was missing since it is usually emphasized in articles discussing invasive pests. I spent last summer on Lake George and saw the absolute devastation of the Gypsy Moth. I also saw the Gypsy Moths…. Everywhere…. So many wrapped up in the trees they blocked out the sun. Seeing how much damage an insect could do was jarring. The only good thing was that the trees still had a decent chance of bouncing back. To know that this pest is basically destroying from within, right under our noses, yet totally hidden, is scary. I hope awareness spreads about this issue. I’m in north Jersey and I read today the article about the insect being discovered in Oregon. A tree in my apartment complex had been leafless since last fall. I noticed recently the bark was cracking. I just so happened to start googling tree issues because of another trees bark, and I couldn’t believe that when I looked underneath the bark through the crack, I saw the tell tale signs of the insects. This tree is huge, was beautiful, and very close to power lines. I just went through my photos past year in a half and realized the tree had been exhibiting signs that it was in trouble. As far as I know, no one noticed and nothing was done. Even with professional landscapers maintaining the property and spraying it. Our complex in Passaic County is ust down the street from Apshawa Nature Preserve, a special area with bears and beavers and it’s just beautiful (also where NJ only fatal recorded bear attack occurred a few years ago). I just can’t believe there wasn’t more of an aggressive campaign to prevent the spread. Disappointing, but not surprising. I know finding the right way to do prevention is still evolving and isn’t easy, but if this tree in a major apartment complex rotted away in font of everyone’s eyes, how many others in the nearby woods are doing the same? The woods go from behind my complex to NY state. It’s just sad. Thanks so much for this video. So informative and definitely one I’ll share to spread the word!

@Andrew The Arborist What is killing the hickory trees in the southeastern US? I've personally lost several and they usually have holes like this, but from what I've heard, the Ash-borer isn't the actual culprit as it doesn't attack hickories.

I'm in Massachusetts and I was going to transplant a white ash sapling from my parents yard to mine, but it's probably not a good idea after watching some videos tonight... 😢

I have about 8 ash trees around my house that this spring didnt grow ANY leaves at all, they're all dead, I had to cut one down last week that had a trunk about 22" diameter

They have now been found in one city in Oregon

I was told by an old farmer that chicken manure spread around the base of the tree will save the tree . I personally do not know, can you tell me if this is true ??? Peace v

Its in new mexico too. Im treating my fruit with an insecticide specialty for bore

Can you do an update on this please?

I swesr i saw one in the Seattle srea tjeee years ago. I remember it because it was so pretty. I tried to get a photo but womeone shooed it away

Dont they also spread a fungus?

Another gift from the chi-coms

Wait, you mentioned just how prevalent and widespread the north american ash trees are. Does having a larger population of a tree that is susceptible to a damaging pest or disease make permanent ecological damage and mass extinction MORE likely than if the tree population was smaller? Like, the more at-risk trees we have, the more likely we’ll lose them all?

Dadgumed EAB may well put Louisville Slugger out of business.

i don't understand why we can't just use the already dead trees for fire wood. but the officials around my area say that they can survive the burning and the smoke will infect near by trees with new eggs, i do not believe any of that at all! could some one explain that more please?

@Andrew_the_Arborist

Firewood from dead trees is perfectly fine to use, as long as you keep the wood local. Don't move firewood around or drive it to other areas, as that could spread the insect. The insect won't survive the fire, but they can escape from the deadwood during the process of transporting the wood. Hope that helps!

my cherry tree have white bores, I been working on my tree, I hope my tree alive 😢

Debark ALL the ash logs, install woodpecker bird nest houses.

I lie in missouri ive seen 250 year old ash trees have to get get chopped down due to its death from EAB i havent seen a living ash tree where i lived sonce 2019, now our woodlands are 25% dead ash

3:49 Baynet ain’t report this? Mustn’t be real news lol. This isn’t good but the Giant Hornet is more a worry to me. Who knew ww3 would be won using insects.

This video only has 11k views and 200 million ash trees being destroyed by a big imported from China 🇨🇳

Why not start importing the Asian ash and plant that instead of american
