More drains and a new liverwort

This drain runs roughly north to south along the retaining wall back terrace and turns at a right angle round the corner below.

I've removed most of the ferns so I can clear the drain

Making the water that seeps almost continuously down the hill run round the terrace edge rather than straight across it and into the wash-house means we have a dry(ish) threshold. It also turns out that maintaining drains is fun because you find stuff. I found more Trailing St.John's-wort (Hypericum humifusum) and more Toad Rushes (Juncus bufonius). See left; a Toad Rush is 'bridging' the ditch at the right-hand side of the pic. Most importantly though, I found a new species of liverwort, one of the Riccia genus. I'm sending a sample off to be identified and recorded properly.

It's quite tricky, I found, to photograph a small liverwort in situ when its 'situ' is a more or less vertical piece of ditch bank on the ditch side farther from a retaining wall. The exercise requires an old camping mat to prevent one from getting soaked lying on wet ground for a start. I suppose I could have just got soaked, being so close to home but I probably would have given up sooner in that case.

I found an old stone painting of Toadlet's and used it to mark opposite the spot of my discovery. As it happens I found more of the same Riccia as I cleared out the ditch further.

Some animal wildlife kept me company: this tiny moth decided to flutter about in the wheelbarrow into which I was chucking ditch dirt.

A caterpillar on the wall was charging around (in caterpillar terms) for quite a while among the hornwort,

and a rather weary looking Angle-shades moth  decided to walk up my arm at one point. I repositioned him on a lungwort leaf where he stayed for the remainder of my ditch digging time.
