Are Elms Going Extinct?
Are American elms on the verge of extinction? Contrary to this concern, American elms exhibit a unique trait of precocious seed production, often yielding seeds at a young age, even before they fall victim to Dutch Elm Disease (DED). This distinctive characteristic significantly reduces the immediate threat of extinction for the species. As of April 27, 2022, American elms are not currently at risk of extinction.
Are Elm Trees Coming Back?
Are elm trees making a comeback? The future of elm trees looks promising. If you’re interested in planting a young elm tree, you have several hybrid cultivars to choose from, specially bred to withstand the challenges posed by Dutch Elm Disease and beetle attacks, which have historically threatened elm populations. These resilient hybrid cultivars not only ensure the survival of elm trees but also contribute to their resurgence in various regions.
Why Are All The Elm Trees Dying?
What is the reason behind the widespread decline of elm trees? The alarming decline in elm tree populations is primarily attributed to Dutch Elm Disease (DED), a devastating ailment caused by the invasive fungal pathogen, Ophiostoma novo-ulmi. This disease has been observed to affect elm trees across the state of Minnesota. One of the primary vectors responsible for the spread of this fungal menace is the elm bark beetle, which transmits the DED fungus when it feeds on the trees. Additionally, the DED fungus can also spread among neighboring trees through underground root grafts, further exacerbating its rapid dissemination. Fortunately, there is a means of safeguarding elm trees from DED infection – the application of fungicide injections, which can effectively shield them from infestation by the bark beetles.

Today, short-lived elms can still be found in forests, but because they tend to be much smaller, they no longer play such an important ecological role. A multifaceted collaborative effort is underway to restore the stately and once dominant American elm to persist on the landscape of the nation’s forests.Not really gone.
American elm is somewhat precocious, producing seed at a young age before they succumb to DED, so the species is not at risk of extinction.Elms aren’t going away. If you’re set on planting a young elm tree, you can choose one of a number of hybrid cultivars that are tolerant to Dutch Elm Disease and beetle attacks.
