Great to be back in Manchester presenting my work at #LEUK2026! I shared insights on long-term ecosystem change in southern UK and the impacts of extreme weather on landscapes. Great discussions and new collaborations ahead. Thanks to landscapeecologyuk.bsky.social for such a stimulating event.

Last week I attended the 6th Ecosystem Services Partnership Conference in Prague and shared some of my PhD research 🌱 Great to connect with researchers working across ES & learning how science can create real-world impact. In between, a visit to Milovice rewilding to see nature recovery in action!

Back to school in my home city to give a lecture to a class of young students about science, climate change and biodiversity. A refreshing experience to feel their curiosity about nature 🌱 A good reminder that intergenerational exchange should be the norm when addressing collective challenges 🌍

Great trip to Borneo exploring tropical forests for the first time. Amazing wildlife encounters in properly wild landscapes. Witnessing large swathes of wilderness made me reflect on how much biodiversity we have lost in Europe and how our nature recovery baselines lack so much ambition 🌱🌳

Amazing days attending #TIBS2026 in Aarhus ❄️ The conference covered a wide range of topics showing how complex and fascinating life on Earth is. A key learning was how important it is to step outside my research environment and being exposed to new ideas and intersectional perspectives.

“We cannot withdraw from the fact that over 1 million species of plants and animals face extinction.” IPBES remains committed to its mandate to provide the most credible science and evidence about biodiversity to all decision makers and actors. — @davidobura.bsky.social , @ipbes.net Chair

Right side shows a photograph of a man wearing glasses, dressed in a dark jacket and grey shirt, seated at a conference table with a microphone. The IPBES logo appears at the bottom with the tagline "Science and Policy for People and Nature". The design features white typography on the dark green background, creating a professional contrast.

Meeting a huge ancient tree is always a humbling experience. The Queen Elisabeth Oak in Sussex is one of such trees and a great example of the great historical, cultural, and ecological significance of these big large living beings in the landscapes.

REVEALED: only 5% of Forestry Commission grants for woodland creation have been spent on the natural regeneration of trees, while the remaining 95% is spent on tree planting. The government needs to change the rules. My FOI request & comment in the Guardian: www.theguardian.com/environment/...

Don’t understand the Climate & Nature bill? Don’t think it’s important or needed? @paulbehrens.bsky.social & I wrote this Conversation piece to explain why we should all ask our gouvernements to deliver on their international commitments - and why Friday matters theconversation.com/the-uks-inte...

The UK’s international commitments on climate and nature could soon become law – and better protect our environment
Our best chance of stabilising our climate and adapting to the changes ahead lies in protecting and actively restoring nature.

In the transitioning areas between primary sand dunes and coastal woodlands, one can find nice surprises. Twisted pine trees growing close to the ground as a result of harsh winds. They create shelter for other plants (some rare!) & are threatened by invasive species and soon by sea level rise.

More than 20% of Earth’s plants grow only on islands, finds new research published in the journal Nature. Mapping over 300,000 known plant species, scientists have found that 21%, are unique to these isolated ecosystems. Islands comprise just over 5% of Earth’s landmass. mongabay.cc/ZmnGy8
