-If- this name is signed, it can be added as "name" as mentioned.
https://wiki.openstreetmap.org/wiki/Names#Names_are_not_for_descriptions

If anything is signed it is likely the name of the forest itself ("landuse=forest"), or an L-reference number for the track ("ref=LXXXX").

I have changed the path to a track. For the difference between path and track, see
https://wiki.openstreetmap.org/wiki/Tag:highway=track

I have also removed the description, as it contains no information which is not already mapped (except possibly the forest name, but the extent of the named area is unclear); note townland name is already mapped.
