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.

A eucalyptus boom in Brazil’s biodiverse Cerrado savanna is drying up land and water springs, making subsistence farming more difficult, local authorities and farmers tell Mongabay.

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.

The government needs to change the rules.

My FOI request & comment in the Guardian:

www.theguardian.com/environment/...

Government ‘failing to support natural regeneration of trees in England’

Campaigners say targets for woodland creation are unlikely to be met because 95% of grants are for planting

I've spent the last few months visiting sites in Southern UK collecting remote sensing data on different land management strategies. How stunning landscapes can become when biodiversity & ecosystem restoration is a priority.

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.

Farmers are abandoning land worldwide. What should happen to it?

Ecologists differ on whether to steer recovery or let nature take its course

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

Now out: Great article in the Guardian about Gergana's work on land #abandonment in #Bulgaria and beyond!
www.theguardian.com/news/2024/no...

The great abandonment: what happens to the natural world when people disappear?

The long read: Across the globe, vast swathes of land are being left to be reclaimed by nature. To see what could be coming, look to Bulgaria

Starter pack for proximal forest sensing scientists!

Goal: a diverse list of scientists using close-range tech in forests for whatever scientific reasons (:

Seeking balance in gender, geography, seniority and application.

Please come forward or share it with your colleagues.
