Thanks to Dr. Mike Peacock & Dr. Chelsea Clifford for organising a great workshop for ditch "experts" a few years ago in Liverpool. The paper highlights the importance of ditches in our landscapes.
Lines in the landscape - Communications Earth & Environment
Ditches have many overlooked environmental and societal roles, including impact on biodiversity and pollution, and management strategies to enhance their multifunctional landscape-scale benefits are n...

Check out our latest paper looking at mapping peatland depth and carbon stock at a global scale:

Digital mapping of peat thickness and carbon stock of global peatlands
Peatlands, occupying merely 5% of the Earth’s land surface, are an important carbon sink, storing up to double the carbon of the world’s forests. The …

Planting trees on peatlands leads to more GHG emissions then those trees sequester.

30cm of peat stores up to 327 tonnes of carbon per ha.

Forestry = 145 T Ca per Ha.

It does not make sense to plant trees on peatland as a climate change solution.

Only 800 Tapanuli orangutans are left — and corporate giant @JardineMatheson plans to destroy their only rainforest home for a gold mine. We're calling on Jardines’ executive chairman #BenKeswick to stop the goldrush and halt the expansion -- join now: secure.avaaz.org/campaign/en/...
Orangutan extinction for gold?
Only 800 of them remain, and now a mine expansion could wipe them out. Act now!

A spelling mistake took me on a wonderful journey to Iceland this afternoon. I was trying to type in Scholar and ended up with Holar... So I took a look on Google Map.

There's a university there!

North Iceland looks stunning!!

I want to go....

Launching! 🚀

Today I'm launching a new service for landowners in Ireland who want to rewild their land. I hope this will be the start of a network that will promote rewilding in this country - the time is right!
