So apparently, this can only be cast on improvements if you are an elven civilization?
I had thought half the spell's purpose was to allow non-elf civilizations to benefit from ancient forests without sacrificing improvements. That it simply took a little more work because you had to clear any forests when making improvements, starting 'fresh' from new forests rather than building directly into forests when playing Ljos or Svart.
Or perhaps I confused this functionality with FF?
