What were the big energy and climate surprises of the Trump era? Four years ago, I described the most plausible arc for US climate policy under Trump (it was a boring, safe bet) but expected there'd be unexpected developments too. So how about a look back? https://t.co/1Valz4eTEg

Long thread here... from Keith, on tree guards:

I really don’t want to spread 120,000 plastic tree guards across the side of our lovely hill, the hill where I grew up and now farm, on the eastern edge of the Black Mountains. So, I’ve taken a good look at the pros,... 1/25

the cons and the alternatives, to try and decide rationally, which is the best approach for our plant on the Bryn Arw.

It has become the accepted norm in the UK that to plant a tree, you need to put your sapling in the ground and then wrap a plastic tree guard around it.

This is simply ‘how it’s done’ now. This practice uses a huge amount of plastic; worse still, it disperses plastic extremely efficiently around the countryside. In some rural places, un-retrieved tree guards are by far the biggest source of plastic pollution.

And yet the first commercial plastic tree guards only came on the market 38 years ago. There are many perfectly healthy woodlands and trees that are older than this, and which became established without plastic – which begs the question: do we really need guards?

Plastic tree guards have several uses, some of which did revolutionise tree planting when they first came out. In particular, they:
•protect your saplings from things that want to eat them;
•provide a microclimate, which enhances tree growth, according to the manufacturers;

On Saturday 12/12/20 I saw this on a Facebook group of which I am a member. The comment from the poster mentioned it was taken near Langholm in Dumfriesshire.

It appears to show the use of a forestry plough peat soil

I'm partisan enough to admit that my initial idea was that this might be on Langholm Moor which was the site of a controversial experiment in grouse moor management. I contacted the poster and he sent me this map of the location. Which is not on Langholm Moor 3/19

The location is significant. But before I go into it, a quick explanation of what you are looking at. This photo shows peat ploughed with double mould board forestry plough. Trees are planted on the ridges thrown up, while the furrow drains water. 4/19

The cut in the centre of the furrow is from a 'tine' breaking up a hardened layer of subsoil called an 'ironpan' which inhibits root development. The presence of this pan is the justification for ploughing rather than 'mounding' this site 5/19

As 2020 comes to a close, we're taking a look back at some of our best reporting on the environment.

The American landscape has become 48 times more toxic to insects since the 1990s, a shift largely fueled by rising use of neonicotinoid insecticides.

Banned in the EU, a sophisticated information war has kept these insecticides on the U.S. market.

Amid California's severe wildfires, grape growers in Sonoma County got exemptions to send in farmworkers who have few alternatives or options for support into fire evacuation zones.

With Trump's election, a small and previously marginalized group of toxics apologists suddenly took control over health and environmental regulations, ushering in higher profits for polluters and higher cancer rates for the American people.

Steven Donziger won a multibillion-dollar judgment against Chevron in Ecuador. The company sued him in New York — as of December, he has been under house arrest for over 500 days.
