No Samolus, but not so bad...

Is there a word for the particular kind of annoyance you experience when it has been raining all weekend and the sun comes out on Sunday evening? Brightening-up Rage perhaps? Thanks to the rotten weather (I assume?), we've just had our worst-attended meeting in years - only four of us! 

We didn't refind the Samolus, but we did see Catapodium rigidum Fern-grass and Scutellaria galericulata Skullcap, and a rose with rather stunning prickles (right). So once the rain had stopped, it really wasn't too bad...

Uta, Russell and Ian on the Grand Union Canal
 The interesting thing was that, once again, we were surveying alongside the canal and we were finding species on the Local Wildlife Site criteria list for both mesotrophic grassland (6 spp) and wet grassland (4, possibly 5, spp). 

With 10+ species from the two lists, this stretch of the canal bank would meet the criteria to be designated a LWS for its wet grassland, if it is also seasonally-flooded. Anybody got any good photos of last winter's floods?

The mesotrophic grassland species were Centaurea nigra Knapweed, Filipendula ulmaria Meadowsweet, Galium verum Lady's Bedstraw, Lathyrus pratensis Meadow Vetchling, Ranunculus bulbosus Bulbous Buttercup and Trifolium pratense Red Clover. 

And from the wet grassland list: Angelica sylvestris Wild Angelica, Juncus inflexus Hard Rush, Carex otrubae False Fox-sedge, Carex riparia Greater Pond-sedge and Russell has taken home what may be Carex acuta to look at more closely. We got 94 taxa on our recording card.

You can download a pdf of the criteria species here. And then you can go out and find some more potential Local Wildlife Sites!
