Goodness me yes that does need sorting out ... it looks more as if there's years and years of some sort of creeper which has climbed over a tree .......... which may or may not be alive beneath it.
My first concern is that at this time of year a tangled mass like that is likely to contain active birds' nests and of course you must not disturb them.
I think I would watch and wait ... as the spring and summer arrive you and we will have more clues through leaves and possible flowers to work out what you've got there - I think there may be several plants in all of that.
Then in the late summer and autumn we'll have a better idea of your options.
