Bypass Conservation

Whilst jogging back along the bypass between Llanelli and Loughor, I was forcibly reminded of just how much of the UK's nature inhabits the verges of the roads. I have never seen such a density of orchids [mainly Southern marsh orchids (Dactylorhiza praetermissa) but including some nice Bee orchids (Ophyys apifera)]. There was also the white variant of the Slender thistle (Carduus tenuifloris) and lots of Tufted vetch (Vicia cracca). Cars do protect some interesting stuff (so long as motorway 'gardening' is done sensitively).
