I've just come across a reference which is relevant to the discussion of
a week or so back, about bryophytes and herbicides.

Merwin IA. 2003. Orchard-floor management systems (in Ferree DC &
Warrington IJ (eds) Apples - botany, production and uses. CABI. He cites =
(p 310) several studies of orchard floor vegetation and notes that
'Long-term use of certain residual or post emergence herbicides on the
orchard floor has promoted the growth of Bryum argenteum & Marchantia
polymorpha layers. These are resistant to traffic, and do not compete
with the trees.
