Does anyone have any ideas what this could be? It's clearly snapped off from a larger piece. Was found 153cm below ground in pond sediment. Is about 3mm wide and I don't know how long the original would have been.

Another puzzle if anyone is game. This seed was found in pond infill soil. I'm hoping to use it for radiocarbon dating, assuming it's from a terrestrial plant. I took a guess that it's a Restharrow? Any thoughts?

Can anyone out there help me to identify these little spotty ovals that I am finding in pond sediment samples? They look like miniature leaves on a little stalk..in some samples I have 100 and in others I have none. Wondered if they might be something fungal rather than plant related. Any thoughts?

Here's another tricky one.. just can't find these anywhere. They look like miniature leaves on a little stalk..in some samples I have 100 and in others I have none. Wondered if they might actually be something fungal. Anyone got any ideas please please

How do you get a 120% increase in wetland plants in the farmed landscape & massively increase water beetle diversity too? The answer is restore farm ponds by scrub & sediment removal - key is to go in hard & make a big impact. See new paper: share.google/VVowsJzqHdPT...

Thoroughly enjoying the @ialipa2025.bsky.social conference in Aix-le-Bans. One day in and I've already met so many fabulous people. What a supportive and inclusive bunch! Loved sharing my research on ghost ponds, and looking forward to more presentations tomorrow

Sampling #ghostponds before & after ressurection today with @hayleymcmechan.bsky.social & the MSc Conservation & MSc Aquatic Conservation teams on our @uclgeography.bsky.social fieldcourse to N. Norfolk. Utter madness!

What a fabulous couple of days of engagement with the Freshwater Biological Association 💦 and its inspiring memebers. I left with a sense of real belonging amongst these freshwater scientists and conservationists and am totally fired up to continue my work in pond resurrection activism beyond my PhD

An honour to host @freshwaterbio.bsky.social at NTU. Truly inspiring speakers including @carlsayer.bsky.social @davetickner.bsky.social @louiselavictoire.bsky.social @steveormerod.bsky.social. The time to act to protect our freshwater ecosystems is NOW.

Waiting with anticipation to see what grows 🌱 from my ice age ghost pond muds 👻. Had a lovely time at Wakehurst place last week dividing the sediment samples into germination tanks and tucking them in all cosy under their little 45micron night caps 😴

And today for my PhD... I'm making 45micron hairnets for 85 fish tanks.. obviously!

Really enjoying the beginning of my macrophyte propagule identification journey. This beautiful collection is just a few macrofossils that I picked out from a resurrected ice age ghost pond in Norfolk. Not all propagules but pretty none the less

This month my palaeoecology journey begins. Yesterday my lovely #UCL team and I made a "mud masterplan" plan. I have 58 sediment samples from ice age ghost ponds to work through. I'll be seiving, picking out, identifying and counting aquatic plant macrofossil from these rich seed banks.

The most successful form of #pond conservation is the re-excavation of deliberately infilled #ghostponds. Here = 2 years of colonisation in a Norfolk ice age #ghost filled in for farming. An incredible pond results at fierce speed! @timholtwilson.bsky.social @hayleymcmechan.bsky.social

Thank you Liverpool and #BES for a fantastic couple of days. Went to some inspiring talks, took many photos of useful posters and met a load of lovely people. What a friendly bunch us nature lovers are 🤩
