which salix is it?
as well as the white marks that Hazel mentions, some areas of the trunk look very dark. Is this wet or a light effect or are they a different colour?
That doesn't look good, trees drop leaves in times of stress but clinging onto the dead ones isn't a good sign. Have you had drought? It's been very wet here up to the last month and nothing that's been in place for 12 years is suffering from drought.
