RoobyDoo: Came out today to check on the cache and replace if necessary.
However, the location is extremely close to a section of the footpath, which has been fenced off, with warnings of a highly toxic plant.
It looks like Giant Hogweed. I have decided to archive the cache as I don't want anyone to be affected by this (I've seen the effects on my daughter). Obviously, the footpath is still open, so the public can get past if they wish.
