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

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.

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

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.

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

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.

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

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.

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.

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.

First record of Daltonia splachnoides for co. Antrim (VC H39) and the most NE Irish record so far. Closest known site (my record from Monaghan the other week) is 100km SW of here.
Found on a willow in Glenariff Forest. Very happy.

A very unnatural woodland but there are some lovely patches of native trees and temperate rainforest cryptogam biodiversity - but could do with serious ecological restoration.
