Resistant trees
The Red Elm is not mentioned as being among the 'resistant trees,' and therefore no explanation is given, either, as to why it hasn't played a greater role in the resistance programme. —The preceding unsigned comment was added by 212.100.250.218 (talk • contribs).

Role of climate change and woodpecker decline
It seems likely that either or both of global warming and decline in woodpeckers, which predate on beetle larvae, itself resulting from reductions in the area of mature broadleaved woodland, losses of non-woodland trees including elms, increases in woodland isolation and reductions in the occurrence of dead wood (Vanhinsbergh et al. 2001) are candidate causes for the spread of the disease (http://www.bto.org/birdtrends2001/wcrleswo.htm), but we will need a reference for the first.

Populations of Downy and one other Woodpecker species native to North America have substantially shown recovery since the introduction of a new exponentially building larval food source, Emerald Ash Borer. Woodpeckers extreme behavior during todays Extant & Extinction of Fraxinus has now been well documented after causing unprecedented "Flecking" of whole trunks and limbs when foraging for EAB larva over winter. Never before have Woodpeckers been observed causing this much extensive damage to bark, when searching out native phloem borer larvae over past human history.CHICAGOCONCERTMAN (talk) 02:50, 31 May 2015 (UTC)

Eradicating the beetle
The article makes no mention of any efforts to eradicate or control the beetle itself, thus preventing, or limiting, the spread of the fungus. If any serious work by entomologists had been done on this, one would assume it would have been mentioned in the article. As this line of reasoning will surely occur to most readers of the article, would it not be a good idea for the botanists to explain why it is not worth while attempting? —The preceding unsigned comment was added by Special:Contributions/ (talk)

B-Class???
I don't know why Wikipedia rated this as a B-class article it seems more like a C-class to me, this is why:

It does not follow a consistent structure, with info scattered around,

In my opinion it should have more info about the cause of the disease and less info about where it has originated... so on

I don't think its a bad article so much, just that it could be a lot better, I will try and fix it up with some of your consent.Mike of Wikiworld (talk) 08:30, 3 May 2010 (UTC)

Spread of disease
Even though this is an English languaged encyclopedia, it does seem a bit strange that the "Europe" section only mentions the disease in the UK, followed by sections labeled "United States" and "Canada". I presume this disease also existed outside of English speaking countries? --Saddhiyama (talk) 23:18, 6 August 2010 (UTC)

Anti- Dutch Trig
There is this uncited statement in the Preventative Treatment - Biological section: "Trials in the US most notably Denver Colorado showed that Dutch Trig had a dramatic effect Elms and that the treated trees were made sick by the treatment." I believe the source for this statement may be this forum user's posts here where the poster also appears to be confused about how the preventative treatment is supposed to work: of course the trees are uninfected. Also this statement, flat out contradicted by the trial results. Reading onwards, this individual also has a relationship with a competitor to Dutch Trig. Okay. Anyway, all the more reliable sources I can find state that the Denver, CO, trials were highly successful, so I'm deleting this unsupported statement and replacing it with cited info.118.209.46.88 (talk) 05:27, 5 August 2013 (UTC)

Spanish version photos
The Spanish GA version is much shorter than what we have, but it does appear to have some superior photos. If anyone wants to rework this page, I'd suggest borrowing some from there. &#123;{u&#124; Sdkb  }&#125;  talk 05:28, 18 February 2021 (UTC)
