From the shape of the leaves it should be an Elm tree, and I would opt for Ulmus glabra (European Mountain Elm) This Elm is deciduous so if you took the photo in Winter, than its not U. glabra :? Do you know the leaf sizes?


We have a more common Elm (Ulmus minor) but this do not grow that tall, and usually in more shady / humid places, such as along Wied il-Luq, Buskett.

Also be aware of hybrids between different species of elms, though yours looks to me to be U. glabra.

many Elms were introduced by the Brittish and have 'spoiled' the native genetic pool.

Thanks admin, I have looked up the types on the www and the leaves actually resemble more the Ulmus minor tree.

This tree is considered an alien species with the following threats:
1 competition for resources
2 Displacment
3 Hybridisation with native taxa
4 Introduction of new diseases or parasitic.
(I am quoting from http://www.mepa.org.mt/environment/publ ... ap-bio.pdf )

On the other hand though, it is afforded the greatest degree of protection (Schedule 1) of LN 12/2001 !! (http://www.mepa.org.mt/environment/legi ... 2001_E.pdf)

Can someone enlighten me!?

Hi,

From LN12, the species of Elms which are protected are

Ulmus canescens [=Ulmus minor ssp. canescens]
Ulmus minor [=Ulmus minor ssp. minor]
Ulmus procera

Ulmus minor s.l. are the native ones though I do not know anything about U. procera.

Re ID, the specimens of U. minor that I have seen are small trees less than 6m (hence my suggestion on U. glabra), though U. minor is reported to grow 30m - 35m on the www, so could be the common species afterall

due to strong shifted base of the blade: should be glabra!
