Cascading climate impacts and adaptation in miniature. After a night of torrential rain in #Edinburgh, topsoil and charred debris washed down a gully from the area burnt in this summer's gorse #wildfires on Arthur's Seat. Historic Environment Scotland's […] [Original post on fediscience.org]

A fan of dark soil spreads across a road from a gap in red/white traffic barriers, below a gully in the steep South side of Arthur's Seat, with blackened gorse bushes up the hillside.

Well no thanks @Fairphone for dropping support of the FP3 last month. Not great when the USB port stopped charging (1% per hour?) and my #InterRail pass to get home from 4500km #StayGrounded trip 🚅🏴󠁧󠁢󠁳󠁣󠁴󠁿🇧🇪🇩🇪🇩🇰🇸🇪🇳🇱🏴󠁧󠁢󠁳󠁣󠁴󠁿 was only on the phone 😬! So yay […] [Original post on fediscience.org]

Giant redwood / 'Wellingtonia' in the palatial grounds around the African Museum in Tervuren, outside Brussels. #ThickTrunkTuesday #Belgium

The rugged red bark of an early mature redwood stretches from the camera away into down-sweeping branches.

Clinging on to the clifftop, where the path drops out of the sunlight. Dunglass, East Lothian. #ThickTrunkTuesday #Trees #Scotland

A low rock face in shadow, with a big, contorted oak root clinging to the top. The trunk rises above, balancing just over the drop. To the left, the path leads away in a tunnel of low trees.

Solid ash by the remains of a drystone wall, above Stirling, #Scotland. Seen a lot, will it see off ash dieback? It might well. #ThickTrunkTuesday

Broad ash trunk rising from green grass into light blue sky, with moss and white lichen covering the bark. Younger deciduous trees on the slope rising behind it, not yet in leaf at Easter.

Still rooted. Oaks in Roslin glen above the gunpowder mill, at the #GoldenHour. Zoom in and crop? Feel free. #ThickTrunkTuesday #Scotland #Trees

A cliff over the North Esk river with two trees growing partly, or entirely, over the edge. Leafless as it's early March in Scotland. One oak is a good 15m tall with a wide canopy, all suspended over space. The last Spring sun of the evening has the whole scene in golden tones.

@Ruth_Mottram Agree! Only took me 30 years 🌳 and still not far from the lab...

Not very far from the lab. View from a tree on campus, ropes and gear to the left.

Willow in the marsh, polypody ferns. #ThickTrunkTuesday #mosstodon Find a #rainforest in the UK? 👀 ➡️ map.lostrainforestsofbritain.org HT Guy Shrubsole et al.

Willow trunk leaning over a still, dark backwater. It's covered in moss with a few polypody ferns, one of the indicators of temperate rainforest in the UK.

The splendid Napoleon Oak 🌳 in its 248th year, now on the campus of the University of Lausanne. ➡️ en.wikipedia.org/wiki/Napoleon_Oak_… For this tree, #UNIL researchers tested how many 🧬 mutations have accumulated over the centuries […] [Original post on fediscience.org]

A huge oak in an open setting, with large low branches all around despite some limb removals. Two photos stitched together by Microsoft ICE software.

First snow reaches the larch roots, over 2000m 🏔️ . #ThickTrunkTuesday

Forest floor with rocks so close below that the larch roots are snaking around in full view, and now dusted with snow.

🚄 Eurostar check-in is still the weakest link, on this trip in Paris rather than London. Bit of a wait to get through the distant door circled in green.

People queuing, a dozen wide, into the distance.
