When felling a tree or part of a tree which is determined to be a hazard, photographic evidence must be retained to prove that it was a hazard and must be provided on request.
Pan fydd angen trwydded/caniatâd a’i fod wedi’i rhoi, rhaid cadw’r drwydded a sicrhau ei bod ar gael i’w dangos os gofynnir amdani.
