Traeth Glaslyn - 26th August

What a lovely day we had - a super reserve and we were blessed by the lovely late summer sunshine that has been such a wonderful compensation for the long, cold spring. We were 9 members, one of the best turn-outs ever: I've circulated a list of 165 species seen, and there may be more to come. I think we all felt there is more work to be done in this area, and I look forward to a return visit at a different time of year.

Looking north up the Glaslyn river
to the new bridge carrying the A487 
We spent a long time recording in the lane which runs alongside the reserve and perhaps we would have been wiser to get up to the alder carr at the north end first.  However we made an excellent list with several names new to the hectad mostly due to more accurate recording such as Pastinaca sativa subsp sylvestris, Wild Parsnip rather than P. sativa s.l. Non-native species included Red Oak, Quercus rubra, Wilson's Honeysuckle, Lonicera nitida and Lodgepole Pine, Pinus contorta, all planted, and a lot of a Michaelmas Daisy, Aster, provisionally determined as  Aster x salignus.

Persicaria minor

On the reserve itself we were pleased to find Eleocharis parvula, Dwarf Spike-rush, washed up in the more brackish pans to the south of the area we covered, and Persicaria minor, quite abundant in many parts of the northern, less-brackish areas.  It was a pity to see so much Crassula helmsii but it seemed to be well-confined to a single area, perhaps where the vegetation was less robust and it could get established.We got a very good list of other freshwater and brackish marsh plants but didn't find the iconic plant of the reserve, the Welsh Mudwort, Limosella australis. Better luck next time!

Osprey watching at lunchtime

We had an idyllic picnic in the sun on the water's edge and the crowning delight was seeing an Osprey flying over the river.  We set off home in ones and twos, well-contented with the day's work.
