Nice to see an urban tree with plants around the base like this one in #Naas. It would be great to see more #suds landscaping in our towns & cities. #urbantree #Kildare

"Like Conor Pass, the ambition is to expand the number of national parks and protect biodiversity"
- Minister of State for Biodiversity, Christopher O'Sullivan.

With all our EXISTING national parks severely overgrazed, rectifying *that* should be the priority.

Have you ever wondered what the Somerset Levels might have sounded like in the late Iron Age?

Worth a watch....

Fairly tame #fox has appeared in the garden. Good to see it keeping rodents in check.

Do you know of any large old Elms in Ireland?
We're looking for really big old elms which have survived elm disease, despite it spreading everywhere across the country.
Please visit our dedicated website and let us know about any veteran elms out there!

1. Against my own political instincts, I’ve taken what feels like a drastic step, and started stockpiling food. This week’s column explains why.

Plus a brief thread.
Britain’s food supply is precarious – and Trump’s chaos is spreading. I have a plan. Do you? | George Monbiot
I’ve started a stockpile, but that isn’t the answer. If crisis strikes, the government needs a strategy to protect us all, says Guardian columnist George Monbiot

Thinking of growing butternut squash this summer?

If you are, why not try our open pollinated early butternut squash?

Most early butternut squashes are F1 hybrids. Ours isn't and it is seed saving friendly.

Prof Dominick Spracklen just explained on @channel4news.bsky.social how reintroducing 167 wolves in the Scottish Highlands could reduce red deer population enough to boost woodland regeneration, leading to 1 million tons of CO2 sequestred per year.

Seems unhelpful: artificial feeders in woodland, feeding competitors & occasional nest predators, at a vanishingly rare site that still has Willow Tits in southern England.

Putting up feeders in Willow Tit habitat is like going to a Little Tern colony and throwing bread for the gulls. #ukbirding
Right then. North Devon.

Firstly looking for Willow Tits, and at a publicised site, there were slight issues finding them.

I'm with The Shadow when it comes to these furry pests, where's a Goshawk when you want one??

We knew pet tick & flea treatments contaminate every river via domestic effluents. Now we see they are poisoning bird nests too. These hideously ecotoxic compounds are already banned in agriculture so why are they still freely available for pets? www.pan-uk.org/garden-birds...

Found what I think is a #squirrel drey on the ground in Avondale, Wicklow today. Knocked by recent storms. I thought it was moss initially, but it's shredded bark. Possibly from these nearby conifers.

There's something absolutely tragic about the #Brigid's light atop the historic Hill of Allen, seat of Fionn MacCumhaill, shining out over the Kildare countryside, while metres away Roadstone have quarried away our collective heritage.

I will never understand how this was allowed

"Between a rock and hard place" garden in #Carlow town. It was planted up last year, so it'll be interesting to see how it develops as the plants become established.

By dawns early light... I was worried that the scots pine wouldn't keep up with the birch, oak and alder, but I guess I was wrong.

Reminder for Irish readers. Oleg owns Aughinish Alumina near Foynes; an environmental time-bomb also, as it happens.
Oleg Deripaska was named in Senate Intelligence report as working with Russian intelligence to subvert elections across the world. Aka Lord Mandelson’s friend.

The fact that Starmer is so indebted to him that he gave him this gig is honestly alarming

Did you know that Snowdrops (Galanthus nivalis) aren’t native, but an introduction from Europe first recorded in the wild here in 1778? Another fun fact - the highest Snowdrops recorded in Britain were at 1,345 ft, above Ullswater in the Lakes. #wildflowerhour
