In reply to Richard Hall:
I won't be there, unfortunately, but I did have an idea on my ride into work this morning.
I was climbing at Main area a week or so ago, and I noticed that plenty of greenery was starting to grow in the cracks and holes as warmer weather arrives. I know that we need to control certain species, both ecologically and to keep the climbs clear. However, I also know that there are certain species we are keen to protect. Does anyone in the Steering group (or anyone else) have enough botanical knowledge to produce an easy-to-use gardening guide?
