So a small number of the green spaces I’ve visited have been closed. There’s a different challenge with Farm Bog on Wimbledon Common – it’s very difficult to find.

I resort to trying out a number of small paths which go south from Robin Hood ride and seem to be going in the direction of the valley bottom where I think the bog must be. Each time I leave the main path, I leave myself an arrow marker so I will be able to retrace my steps.  I’m worried that I will spend the rest of the day wandering lost round Wimbledon common.

On path is partially blogged with fallen silver birches and I climb over to immediately sink almost up to my ankles in sopping Spagnum moss. It’s a relief.  I wasn’t planning to explore the bog beyond the margin as I don’t want to damage anything but I find a couple of different rushes – soft and jointed I think – and a pale yellow flower which is Small Balsam (Impatiens Parviflora).
