Dying conifers

[woody paul]

On a job today and nearly every conifer has signs of dying, lawsons, thuja Leylandi and Scott's pine they are over multiple gardens and piece of woodland near by any ideas. Pictures are of Thuja.

Conservation Area?

What about preservatives from the telephone pole ?.

Given the range of species and location, my first thought would be abiotic, so herbicide drift / salt spray / root disturbance from utility trenching and the like. 
Any of these fit with what you saw?

[woody paul]

None of a the above. The area I am look at is over 10 acres and dead end road. Also found a Beech tree that has died plus walking up road couple of holly hedges that don't look good.

there is a disease in our area that is killing off lawson cypress, not sure what it is though.

doesnt seem to be  efffecting leylandi though.

[JSN]

In that case - Frost damage? Is it in a frost hollow? Possible root rock from storm Arwen? 
Obvs clutching at straws and doubtful but a possibility nonetheless.  Also could be individual pest / disease. 
If genuinely concerned / interested, you could report to Forest Research.

Salt spray or herbicide are the only two I can think of

is the grass around the hedge in the first photo dead aswell?
