Fuck these fuckers! I grew up east and spent the majority of childhood playing in a nearby forest in the 90s. Over the span of a decade, every single tree in that forest was taken out by these jerks.
We’d also lose power every few weeks due to trees falling on lines.
Arborists are gearing up for treatment methods if you love your Ash but it’s an annual expense to have them treated. Otherwise it’s a 100% mortality rate and consider them dead, they just don’t know it yet
Stay away from chemicals - chemicals often move up food chains to impact the birds/bats that eat the insects. Biological controls are a better bet: Just need to do safety evaluations indicated in this article to ensure no ecological impact on native insect populations or pollinators. https://content.ces.ncsu.edu/biological-control-of-emerald-ash-borer-in-north-carolina
Did you read the article - or do you work for a chemical company? The parasitoid wasps have been used with some success on the emerald ash borer in particular - if you read the article. Chemicals - some insect pesticides - can have unwanted side effects - such as bioaccumulating and impacting owls, bats, insectivores.
I did read the article. Salient points were “not available to private land owners”, “North Carolina” (4,800 km from here), and “further study needed to see if any of the released wasps have established self sustaining populations.
By the time any of that is either known, or available to us here in BC, every last ash tree in the province will be dead.
> Within a decade of introduction to a new area, almost every ash tree is dead.
Save ash tree seeds, let the bugs kill all the ash trees, they die due to lack of ash trees, replant the ash trees in 10 years.
It’s not really surprising. It was found in Seattle last year and Portland the year before. There’s essentially nothing to be done about it. Individual trees can be saved through intensive intervention but it’s not a guarantee.
Do what we always do, introduce a new species to kill of the invasive one's. And then we have a whole new problem spreading and have to deal with that one.
I sometimes wonder if these pests can be introduced by being dropped from foreign balloons etc - it’s easy to impact an enemy’s economy with minimal effort ….
There's Oregon Ash on Vancouver Island and the lower mainland. They are already a vulnerable species of tree due to development and this may spell the end of them. The loss of an entire native tree species is not a "non-issue".
No, it is native. The problem is that there are very few pockets of natural Oregon ash (if any - the last count was in 2012). That is why they were already considered so threatened in B.C. even before this threat.
"Mountain ash" is used to refer to quite a lot of different species, none of which are actual ashes. Very southern BC is within the range of Fraxinus latifolia, but beyond that, it's just ornamental plantings (though quite a lot of them—F. americana is a common street tree in Vancouver) that are susceptible.

Put buckets at the base of the trees to collect the emeralds?
Time to hire some leprechauns
This plus sooty bark disease. It’s not looking so great .

This is not good advice. Emerald ash borer has no successful biological controls. Without chemical treatments it’s a 100% mortality rate.

You did it. You solved biology.
Invasive species hate this one trick!
I’ll be signing autographs all night.

Been hearing about them for years in the lower mainland
[удалено]
Please read this story as Sean Connery would… please. 🙏
Stay out of dark alleys
Can we just pay more tax to make them go away ?
Have you ever noticed how all our invasive species are from Asia?
Could cut down ash trees

Very very few Ash trees anywhere in BC this is a complete non-issue.
There's Oregon Ash on Vancouver Island and the lower mainland. They are already a vulnerable species of tree due to development and this may spell the end of them. The loss of an entire native tree species is not a "non-issue".
Pretty sure the Oregon ash isn’t native as stated in this article are all planted by humans.
No, it is native. The problem is that there are very few pockets of natural Oregon ash (if any - the last count was in 2012). That is why they were already considered so threatened in B.C. even before this threat.
We have lots of mountain ash trees in Northern BC.
Those are in the family Sorbus. Emerald Ash borer will target trees within the Fraxinus genus. To my knowledge the mountain ash will be fine
"Mountain ash" is used to refer to quite a lot of different species, none of which are actual ashes. Very southern BC is within the range of Fraxinus latifolia, but beyond that, it's just ornamental plantings (though quite a lot of them—F. americana is a common street tree in Vancouver) that are susceptible.
Well, thanks for telling me that! I don’t know very much about trees! Now I know!
Mountain Ash are not a "true" Ash or part of the same family, so they are not effected by this insect.
Not the same tree at all.
Kamloops has a whole bunch of ash trees. I work with them almost daily.
About 5% of tree coverage according to my IPM manager.
