- Colura calyptrifolia on rowan and plentiful Hyocomium armoricum on granite boulders at Yellow Water, Rostrevor, Co. Down How amazing would this place be if it had some native woodland? Missed opportunity for restoration
- Thug mé cuairt Uaimh Thalún na Fionnaise agus Liagán Áine, Co. An Dúin inniú Tá an uaimh 29m ar fhad - iontach suntasach Bhí na radharcanna ó Liagán Áine dochreidte, agus na Beanna Boirche ó dheas. Ainmníodh é i ndéidh Bandia an tSamhraidh, Áine
- This is an amazing record if this rare fungi that is closely linked to temperate rainforest. Not before observed in the SE of Ireland!! Wow

- New site record of Hymenophyllum tunbrigense for Co. Louth (H31) growing in a rocky woodland on a minor hill. Happy to find this one today. A very scarce species in the county. @bsbiireland.bsky.social @bsbibotany.bsky.social #ferns #botany #filmyferns
- Reposted by Dean Mac Cú UladhLikely Rhabdoweisia crenulata growing at high altitude on a NE rock face. Another first for me and the maamturks/Mám toirce records it seems. Thanks @nimbosaecology.bsky.social for ID help
- Dryopteris affinis s.s on my St Stephen’s Day walk yesterday. Every day is a good day for some fernology I am pretty confident with this one @bsbiireland.bsky.social @bsbibotany.bsky.social #ferns #botany
- Fontinalis squamosa from Bavan, Cooley Mountains, Co. Louth in upland boulder stream Doesn’t seem to be previously recorded from this region @bbsbryology.bsky.social

- To round up my year of biological recording, here are my favourite finds from each month of 2025! January - Jubula hutchinsiae I re-found this colony recorded in 2004 in the Glen Stream, co. Down. A v interesting & unmistakable oceanic liverwort of humid wooded stream valleys
- February - Rana temporaria Feb wasn’t the most productive month but coming across a huge population of frogs in this upland pond on Camlough Mountain was by far the most memorable. I have never seen so many frogs in one place and the noise was amazing. A humble creature
- March - Cheilosia grossa This large and distinctive hoverfly is an early season species and I am lucky enough to have found it at a few local places this year. It can be found feeding on willow and is generally quite rare. This one was found in a reed marsh north of my hometown

View full threadNovember - Bazzania trilobata This was a lovely large liverwort of humid woodland to find for the first time and marks the best find for November. Ness Country Park in Derry was really productive for temperate rainforest species and will be worth returning to.
- Greenan Lough, Newry, Co. Down These drumlin valleys contain lakes, fen and transition mire. Important habitats for scarce spp like Marsh St John’s Wort, Sphagnum contortum and many wetland birds. Main issue = no public accessibility - I have not explored any of these wetlands properly
- Reposted by Dean Mac Cú Uladh"This is the first time we can say with certainty that European wildcats lived in prehistoric Ireland" A stunning discovery and more evidence that there's a lot left to discover about Ireland's ecology! www.rte.ie/news/munster...
- This woodland site on the Armagh/louth border SW of Newry is begging for restoration. Bounded by forestry on both sides with a deep gorge between, supporting a nice array of species. Also an area brimming in local history, being one of the last Gaeltachtaí on east coast c. early 20th Century
- A deep hollow is know locally as Poll an Mhadaidh/Cove of the Dog (wolf?), now it is just a poor plantation but the fern-rich understory is still there. A few native oaks and ash can be found but also loads of rhodo and Tsuga regen. Historic beech planting too. But the potential is all there.
- First record of Daltonia splachnoides for Co. Armagh (H37) from plantation on Camlough Mountain. Epiphytic on willow, associates were Lejeunea patens & Metzgeria consanguinea. Algal gloop a big issue though. @bbsbryology.bsky.social #bryophytes #moss #Ireland
- Other cool Fermanagh/Cavan finds included Saxifraga hypnoides, Sticta limbata and slime mould Badhamia utricularis. Also visited Shannon Pot, the source of the River Shannon in west Cavan #botany #lichens #slimemould #ireland
- Neckera crispa growing as an epiphyte in a hazel temperate rainforest north of Cuilcagh, Co. Fermanagh. Other niceties include Ctenidium molluscum and Breutelia chrysocoma
- A new site for Neckera pumila from willow on edge of Gortin Lakes, co. Tyrone This colony was particularly robust #bryophytes #moss
- Reposted by Dean Mac Cú UladhFirst time seeing Tunbridge filmy fern (Hymenophyllum tunbrigens) in Omagh yesterday thanks to @dmac00.bsky.social. Such a beautiful fern!
- Some more habitat photos from Ness Country Park, Derry Very impressed with this site and an unexpected hyper-humid microclimate. The Burntollet River was powerful
- First record of large leafy liverwort Bazzania trilobata for co Derry (H40) since 1834! Also growing alongside it was Hymenophyllum tunbrigense which is a new county site too. Ness Country Park, Co. Derry. @bsbiireland.bsky.social @bbsbryology.bsky.social #bryophytes #ferns #botany
- These fragments of hazel woodlands around South Armagh are common enough, and always severely overgrazed. I’ve noted several scarce species from them but they are entirely unprotected. The hilly topography and hard porphyritic granophyre are the only things keeping them alive.

- Lovely lichens from Ards Forest Park, Donegal Lobaria pulmonaria & Pannaria rubiginosa was locally abundant, even on young trees. Pyrenula macrospora was the dominant crustose lichen on ash Other lichens included Pectenia atlantica, Lobarina scrobiculata & Ricasolia virens #lichens #fungifriends
- March in Warrenpoint County Down today with Carlingford Lough Keepers demanding for clean fresh air and an end to industrial malpractice! People and Planet before Profit!!
- 4th Irish record of Endoantria benetecta and 2nd for Co. Fermanagh (H33) - Sliabh Beatha region Little fragments of temperate rainforest on border between east Fermanagh and south Tyrone along the Colebrook River #bryophytes #fungifriends #ireland #temperaterainforest #woodland
- Moody blues over Loch Cairlinn today and a strong high tide. Made Rostrevor Oakwood extra atmospheric
- Storm Amy illustrated why the marshy lowlands of Abhainn Ghleann Rí to the north of Newry are floodplains! I have spotted lapwing in the past along the towpath - now the fields are drained and electric green from slurry. The river and canal are eutrophic as a result. Nice to see corr éisc still.
- First record of tiny hyper-oceanic liverwort Drepanolejeunea hamatifolia for co. Cavan (VC H30) from Tullydermot Falls on Salix sp. One of the oceanic liverworts appearing to increasing as an epiphyte #Bryophytes #bryology #liverwort #temperaterainforest #Ireland #Cavan
- Tullydermot Waterfall, West Cavan A nice selection of rainforest species at this modest waterfall just south of Cuilcagh. Fragments of woodland cling on to the banks of the CLADAGH River. Plagiochila spinulosa and Protopannaria pezizoides were welcome finds. #bryophyte #lichen #ireland
- Cololejeunea microscopica frequent on willows and found the 3rd Irish record of Endoantria benetecta, and first for Co. Cavan. Pretty nice all round but highly fragmented woodland.
- Some more oceanic plants from Glenariff Forest - Harpalejeunea molleri - Hymenophyllum wilsonii - Jubula hutchinsiae - Plagiochila bifaria Really nice assortment of bryophytes #bryophyte #ireland
