I am asking for my last unsolved answer please . This is a local woodland preservation fund raiser. The one I am stuck on has 6 letters ,the question ,50,000 niche.Many thanks.
Lichen would sort of work if the clue had been 50 niche, (L + anagram of niche) although it would really need an anagram indicator. the symbol for 50000 is L with a line over it (Ḹ but without the dot underneath)
