Regarding the effect of Dutch Elm disease on American Elm, as you have =
seen, it has not eliminated the species but has reduced what used to be =
one of the largest trees in eastern Canada to a tree that rarely gets =
larger than 8=E2=80=9D DBH. Fortunately they produce seeds for a some =
years prior to their demise and these seeds propagate easily in the =
correct habitat. I now consider American Elm to be a =
=E2=80=98small=E2=80=99 tree here on my farm.
=20
If you wish to propagate the seeds yourself here is the method for elms =
taken from =E2=80=98Propagation of Trees, Shrubs and Conifers=E2=80=99 =
by Wilfrid and Sheat:
=E2=80=9CThe seeds should be gathered and sown as soon as ripe. Sow in =
rows in open beds and cover to a depth of 3/8 inches. Some of the =
species germinate immediately, though occasionally some will remain =
dormant until the following season. Seedlings should remain in the seed =
bed for a full year after germination.=E2=80=9D

Subject: [NatureNS] Elms in NS

There are plenty of elm trees in the Windsor area. I have a few small =
(~8" DBH) on my small property. There are a number of large specimens in =
town.
=20
Can anyone comment on the species they likely would be? The history of =
Dutch Elm here is fuzzy for me. Internet sources state elms were often =
planted here since ca.1800s. Was European White Elm, Ulmus laivis widely =
planted in towns, or are these likely the native Ulmus americana? It =
seems differentiating the species isn't straightforward. Whatever the =
species, they are putting out seed now. Are there any concerns or =
guidelines for propagating elms now, in the age of dutch elm disease?
