Weir infrastructure in the River Waveney including showing a ramp (covered with stainless steel sheeting designed to assist the passage of eels and elvers up the weir. The bottom of the ramp is missing so the structure is suspended about 1 metre above the water surface on the downstream side of the weir.

Weir infrastructure in the River Waveney as it was in 2018 including showing a ramp (covered with stainless steel sheeting) designed to assist the passage of eels and elvers up the weir. The bottom of the ramp is reaching down to the water surface on the downstream side of the weir. An Environment Agency official is explaining its operation to some people.

The eel pass is out of action at Bungay Weir. It was brand new in 2018. I'm wondering what the story is now at the Environment Agency.
Aren't elvers migrating upstream now? #eels @carlsayer.bsky.social @freshwaterhabitats.bsky.social

There is no need for the hunting of fledgling gannets.
It is not for subsistence but for the gratuitous reproduction of destructive, atavistic behaviour. It is time to stop the practice.

I was wrong: not Olland Street but Bridge St at strapping.reefs.sandwich, so in E.Suffolk. Map in Merryweather says absent in eastern Essex - I wonder why .

Rustyback Fern Asplenium ceterach on a 19th century brick wall. It has pinnately-divided, tongue-shaped leaves growing as a tuft.

Out recording Spring flower activity today at Bungay (Suffolk) @wildflowersociety.bsky.social. Agreeable company with impressive skill-set. My top find was Rustyback Fern (Asplenium ceterach) - not much of a flower but a first for me.

Interesting BBC headline. Actually, it is a blow to Farage too (in case it had not noticed).

It is a matter of profound satisfaction to me to see the Tory party humiliated in this way, but the hydra still lives.

There is plenty still to be done, eg in prep for coastal realignment. But not so much work suitable for people with spades and wheelbarrows.

A new study published earlier this month in Geophysical Research Letters reveals how the tips of tree leaves burn with ghostly, ultraviolet sparks. These phenomena, known as coronas, had never been seen in natureβ€”until now. 🌿 spklr.io/6042DI2EC

Found at Bacton but the cliffs and beach are now engineered to blazes. If the NMI is up for sharing these pics or even 3D scans of the specimen we'd be keen to add it to our project database. :-)

I've been enjoyably working on species profiles for Red Deer, Horse and Hippo (EM Pleisto variants thereof) and Deninger's Bear today. :-)

I'm currently using JC Bach fortepiano concertos as a luminous drug to offset a head cold, while researching & writing Cromerian animal profiles. Mozart would drive me potty though - too roccoco, would interfere with my neurals.

Social media and the BBC tends to colour the world with the lurid colours of oppositional journalism, feeding extremes. Most people just want to build happy home lives and they are looking for a better world. They have a vote.

A mandible of the Scimitar Cat Homotherium latidens. There is a wide gap between incisors and carnassial teeth where the elongated upper canine tooth rested. It was found in the later 19th century in the Cromer Forest-bed at Pakefield/Kessingland cliffs, Suffolk, UK. Figured in J. Backhouse: 'On a mandible of Machaerodus from the Forest Bed', in Quarterly Journal of the Geological Society of London, no. 42.  The scale is 10 cm.

Work on the Cromer Savin Project is hotting up with Cromerian species & landscape reconstructions in prep - to be launched later this year.

Good point. If a culture is so dull it does not attract people to belong to it then it will surely fade out through Darwinian processes.

How do we know it is a 'lion' rather than a 'hippocampus'? Because lions have back legs and clawed paws and hippocampi have a fish's tail.
