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.

Very large pollard chestnut trees in Portugal. Not only they provide nuts, wood and honey but also they are a key cultural symbol for local communities and 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.

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

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.

Great step to recognise the role of IPLC in these areas and ways forward

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.
