Nature Trail: Can the Cottonweed be brought back from the brink of extinction?
Cottonweed, a native plant, is one of the rarest wild flowers found growing in Ireland. It used to grow at five sites nationwide but is now confined to a single site on the south Wexford coast.

1/4 Photos from El Pijeral - 'The Enchanted Forest', Tenerife. Laurisilva forests in Canary Islands are ancient subtropical cloud forests formed in the Tertiary period. Sustained by trade-wind moisture they host many endemic species and relic biodiversity lost elsewhere in Europe

Nice afternoon of botanising in Sliabh Aughty, Co. Clare. Highlights - a new site for gametophyte of Killarney fern and 2nd county record for Polystichum x bicknellii (hybrid between P. aculeatum and P. setiferum) Need to confirm ID of latter but it seem to fit the description 🤞

So sad that Roy Maycock is no longer with us but great that people are celebrating his long & full life, and all his contributions to nature conservation. BSBI County Recorders eg @sarahlambert7.bsky.social @astridbiddle.bsky.social @donncha-oc.bsky.social & @trisnorton.bsky.social do amazing work!

Hello BlueSkiers! I’ve made a starter back of people working on rewilding and similar things in UK and Ireland. Many more to add but it’s a start. go.bsky.app/A7v5ZUQ
