Welcome to the #RLASSymposium! We begin with an introduction to the first #RLASPartnership symposium by Prof. Bridget Emmett OBE @britishecologicalsociety.org. 17 organisations make up this partnership, & we hope it will provide connectivity between #LandscapeScale #LTEs 🌍

I got this book from the Library at Cranfield. It's beautiful, insightful and enjoyable. Published in 1986, it's nearly as old as I am!

Nice panel at my local conservation area in Rotherham. Small outcrop of limestone near a SSSi - Anston Stones. Not many Meadows left around here.

In June 2024, 80,000 of us marched peacefully to #RestoreNatureNow with hardly a mention in the media. Were we supposed to have thrown stones and fought the police to be noticed? www.theguardian.com/politics/liv...

@bbcspringwatch.bsky.social great to see dry stone walls on Springwatch this evening. Since the 1950s we've seen a gradual decline all over the white peak. Gradual feature loss, resulting in shifting baselines.

A HISTORIC MILESTONE: For the first time, solar power generated more electricity globally than nuclear, making it the world’s 4th largest power source. In just 5 years, solar output nearly tripled—from 79 TWh (Apr 2020) to 233 TWh (Apr 2025). The energy transition is speeding up. @ember-energy.org

We need to start to think about ecosystem turnover as a form of ecosystem resilience. Fantastic paper.. "mass-scale assisted colonisation will likely be required not to conserve threatened species, but to maintain functional ecosystems"
