My main concern is that of the ash tree (presumably it is an mountain ash), i am very concerned of this one as she is my pride and joy (roots and form) i was wandering if this was suffering from some kind of black spot or was it Ash Die Back (praying to god it is not and it can be sorted.) I have attached a picture of a mark on the trunk, there a few of these on it popping up i have noticed??

The tree's that seam the least infected are the oak's but are showing some signs of problem now.

I have now separated them.

Any help would be great
Thanks for reading

I have more pics if required - anything to get this problem sorted

It doesn't look like ash die back to me.

From your pictures it looks more like the fungus Rhytisma, which causes tar spots i.e. the black spots you can see.

An appropriate fungicidal spray may help, but before you start any treatment I'd space you trees out more as this fungus is transmitted in the leaves that fall off.
