Climate change will increase forest disturbances in Europe throughout the 21st century Wildfires, insect outbreaks, and storms cause large pulses of tree mortality. Climate change amplifies these forest disturbances, yet their future magnitude and extent remain uncertain. Here, we simul...

Telegraph declines to tell regulator how fake banker story got published The Telegraph has refused to tell IPSO how an article about a made-up banker supposedly hit by school fee rises came to be published.

Extraordinary that the Telegraph is refusing to tell Ipso how its story about imaginary couple Al and Alexandra Moy and their non-existent children Ali, Harry and Barry got published.

European forest carbon and biodiversity policies have a limited win-win potential - Nature Communications Forests are essential for both climate change mitigation and biodiversity conservation, yet how to balance these goals in managed forests remains unclear. Here, using a Europe-wide dataset, the author...

Can we jointly pursue climate change mitigation and biodiversity conservation in European forests?

Only promoting deadwood rather than living carbon stocks!

Not much support for win-win afforestation policies.

What is a forest? Remarkably we don't have a consistent answer to that question,which is why we don't actually know how much forest there is on Earth or where it is. 🌏πŸ§ͺ🌲🌳

cool! Is there documentation of those being original? I ask as we looked at some candidates and it was nearly always anecdotal or indirect (eg garden replanted around 1850). I've been trying to find examples with guaranteed known ages going back that far

They are beautiful but few (definitively) are that old - most of the largest ones with known ages are in the 110-140 y range and then loads in the < 75 bracket. The amazing thing is that they can get so big so fast!

Environmental data justice is key for developing more effective area-based conservation approaches - Nature Reviews Biodiversity Scientists disagree about area-based conservation’s role in addressing biodiversity loss. This Perspective examines how conservation scientists, land systems scientists and political ecologists approach these debates differently and argues that environmental data justice frameworks can bridge epistemic divides, helping researchersΒ to develop more effective and equitable conservation interventions.

V few if any of the original 1850s giant sequoia are still alive (poss a couple in Scotland). Many were planted in the late 19th to early 20th C and they're v popular now. Coastal redwood (diff species) were much less widely planted. Definitely an interesting place to plant one tho!
