This plant was found in Belfairs wood. At first I thought this was Prunus spinosa (Blackthorn) but there were not spines so much as they appeared to be small leaf branches which broke easily.
No identification made yet.
No interactions present.
The broken-off spines fits with this as well, would need better pictures to be sure
