Several Salix which were coppiced last year have developed these broad, flat stems, covered in buds. I have seen it before, but never so commonly as at the moment...is there something which might have caused so many stems to develop this way?

Viruses, fungi and bacteria are all possible causes of fasciation. Both fungi and bacteria like damp conditions so may have thrived over the last 18 months.

We see it a lot with

We see it a lot with Forsythia and Veronicastrum, if I remember correctly its caused when the normally dome shaped apical merisrem becomes distorted to a crescent shape (a section of the fasciated material would be this shape). This I think is caused by an external factor in addition to the ones mentioned above ive read frost can also contribute

Bearing in mind the exposed location and the weather this early winter, that might make sense. It was the number of stems affected that was unusual...so something like frost would fit with that. We'll never know, I suppose!


Edit: Those stems will have grown up before these last frosts, of course! Maybe last winter, then...

Yes it would have effect it

Yes it would have effect it early on in growth youre are right so perhaps the buds were damaged early the season. Nearly all the stems on two seperate Veronicastrum plants were affected where I work yet the Forsythia ( which is prone to fasciation) had hardly any but was found on the more exposed side ( coincidence perhaps).
