Tufa formation on a wall on my local stream in south Dublin. Urban petrifying spring meets wall art.

Thanks! It’s a lovely thing. She’ll be sad when it leaves!

Is this a type of plume moth? Very pretty divided wings (I typed leaves fist - botanist error!). Has been living in my daughter’s bedroom!

Bryophyte Rewilding! Bryological shoe found in the Dublin mountains.

There are still places on this talk 'Dublin Mountains Festival; Protecting Our Night-Time Heritage (ISL)' in Glenasmole, Dublin tomorrow if anyone is free. Looks very interesting: www.eventbrite.ie/e/dublin-mou...

Birch regeneration in unmown lawn

Lots of tree planting and plastic tubes in adjacent HS2 land. But in this garden, a few years of not mowing has led to natural regeneration of native oak, birch and hazel.

This Hummingbird Hawkmoth (Mullaghmore, Burren) was one of the highlights on the first day of the BBS bryophyte meeting in Co. Clare, Ireland. 'Moss of the day' trying to be an owl...

Fab - I don’t see them very often these days

Some wildlife in Dublin suburbs this week - 5 herons (including fledgling) and cormorant, River Dodder, Bushy Park; common spotted orchids in meadow at Marlay Park; pyramidal orchid on flowery roadside verge in Tallaght. Local biodiversity is important.

Lovely to find very abundant 'Handsome Woollywort' Trichocolea tomentella in a flush at Old Head Wood, Co. Mayo. A new hectad record surprisingly. One of my favourite liverworts.

Thanks Michael! It is a lovely site. Hope you’re having good mossing!

Very determined and wet bryologists for the Irish Bryophyte group meeting in Killarney yesterday. Despite the soaking we saw lots of lovely species - Ulota hutchinsiae, Grimmia ramondii, G. lisae, Campylopus setifolius, C. shawii, C. gracilis, Schistidium strictum etc.

The NPWS Knocksink Education Centre was a great space for a bryophyte walk and workshop for biodiversity week. Thanks for inviting me.

It was lovely wasn’t it - such a good display too

Cowslips with small bright yellow flowers in a grassy meadow. Tress in distance.

Lovely to see the cowslips at Tymon Park, Dublin, spreading into less species-rich areas of grassland. Often meet locals who appreciate the flowers here - today a several were admiring cuckoo flowers 😀

Another lovely Irish Bryophyte Group meeting - Oak woodland, Glendollagh, Connemara, Apr 25. Lots of oceanic woodland species, but with calcareous rock species too. Nice to see Sphagnum platyphyllum and of course lots of Trichcocolea tomentella. Thanks to @cianoceallaigh.bsky.social for organising.

We had a great (wet) day with the BBS Irish Bryophyte Group on Saturday. The morning in Ravensdale Forest where Jubula hutchinsiae is abundant in the gorge and afternoon at Long Woman's Grave, with Braunia imberbis on nearly every gabro boulder and occasional cushions of Glyphomitrium daviesii.

Looking forward to getting a copy of this when it's published.

Amazing - well done Jo. Looking forward to reading it!

The Irish Bryophyte Group were joined by Chris Preston on Sunday 9th March to record on the shores of Lough Ree nr Lanseborough, Co. Longford. >10 new vice county records made we hope. Highlight was Cian's find of Rhodobryum roseum (which is rare in the midlands) in an old quarry and the sunshine!

The Irish Bryophyte Group were delighted to be joined by Chris Preston last weekend. On Saturday (8th March) we recorded at Birr Castle, Co. Offaly. Great to see the The Leviathan of Parsonstown (telescope) and lovely old oaks. Several new vice county records made (hopefully!) and great company.

Polytrichum commune (Bog haircap) ‘mossicle’ in the Dublin mountains today.

Thanks - it’s slow but quite relaxing at the moment. Next the heel….!

Starting my first ever socks. Very admiring of your two at a time and lovely yarn!

May your 2025 be filled with bryophytes rewilding urban surfaces! Lovely mossy sandstone wall in Kenilworth, England.
