Visited the Lewis Merthyr coal tip above Trehafod last weekend. Once industrial spoil, it’s now heather, whinberry, lichens & warm bare ground supporting specialist wildlife. Conifers are creeping in, so management is key. Even in winter it’s beautiful 💚

Great to speak with the Nature Restoration & Forestry students from Black Mountain College in Treherbert today about coal spoil wildlife. Sharing this knowledge is vital - inspiring future practitioners to recognise the biodiversity value of these sites. 🌿💚

We usually showcase the plants, fungi & invertebrates of coal spoil sites - but here’s some of the hidden life too 🐭

Tufa springs on coal tips 💦
These rare micro-habitats form where water passing through coal spoil picks up calcium - likely from ancient marine bands - and deposits it at the surface. Unusual in the acidic Valleys, and vital for specialist wildlife like soldierflies.

Check out our new insect decline paper. By analysing 36 yrs of German ground beetle distribution data, we show:
- ~80% of species have declined, with significant declines for >50%.
- The decline was similar across species traits and threatened status.

👻 Meet the Ghost Slug this #Halloween! 🐌
The Ghost Slug (Selenochlamys ysbryda) is a mysterious predator that hunts earthworms deep underground. Its scientific name comes from the Welsh word ysbryd, meaning ghost or spirit - a fitting title for a rather elusive creature!

Exploring a coal spoil site near Aberdare today, we found the flat-backed millipede Polydesmus barberii.
This non-native species, first seen in Britain in 1995, has only recently been discovered in Wales. Today's find is just the fourth known site in Wales — and the third in the Cynon Valley!

We also captured some breathtaking drone footage that will feature in an upcoming video for Buglife’s Coal Spoil Connections project.

This year we've been working with the South Wales Trunk Road Agency to survey roadside verges for invertebrates around Merthyr Tydfil. Today we made our final visit to a very special verge in Dowlais. Comprising colliery spoil, it's proving to be a real hidden gem for biodiversity!

Back to Sirhowy Hill Woodlands today to continue the invertebrate survey. The reserve looked lovely, and great to see the bee hotels in use — even spotted a Wood-carving Leafcutter Bee (Megachile ligniseca) basking on one!
Among today's nice finds was the leafhopper Rhopalopyx adumbrata.

Today's guided walks at Parc Melin Mynach, Gorseinon, explored the former Mountain Colliery site.
Highlights included Marbled White, Six-belted Clearwing, Brown-banded Carder Bee, prowling spider Cheiracanthium virescens, and picture-winged fly Herina palustris.
Great turnout despite the heat! 🥵

Last week, @olds_liam led a guided walk for staff & students from University of Bristol at Coity Tips, Blaenavon.
We explored the unique habitats and species of colliery spoil — which included sightings of iconic species such as Bilberry Bumblebee, Mottled Grasshopper, Fairy-flax & Bee Orchid.

Incredible tufa springs seen at the former Pentremawr Colliery, Pontyberem, Carmarthenshire, today - clearly decades of tufa deposits! Around the springs was Delicate Soldierfly (Oxycera nigricornis) and Giant Lacewing (Osmylus fulvicephalus), as well as caddisflies and craneflies.
