Thanks! Weโ€™re investigating how their diet and behaviour differ to sheep so we can use them as another grazing option. Their wild relatives like Molinia ๐Ÿ™‚

Family farmers say their way of life is an impossible dream when โ€˜the bread of life is worth less than rusty metalโ€™ In the Fens of eastern England, small-scale farmers fear for their future amid โ€˜astronomicalโ€™ costs and flatlining income.

We recently had a series of conversations with upland #farmers @uplandresources.bsky.social, scientists & policymakers and we heard and reached similar conclusions - something has to change and dialogue is needed to determine that change

My letter screenshot. Dear Sallie Bailey.
I am really very sorry, but your new peat map, the England Peat Map (EPM) is deeply flawed and should be taken offline as soon as possible, and all conclusions drawn from any of its data should be removed from public discourse and decision making.
I have raised this matter on social media with Natural England, Tony Juniper, Steve Reed, and Mary Creagh, and have not received anything back so I am now bringing it officially to your door.
While I fully understand how so many massive mistakes can have happened during the making of the map, I cannot understand how it was launched without the mistakes being flagged up and fixed. I can only come to the uncomfortable conclusion that within the organisation there is no space for mistakes to be made, aired without blame, and learnt from. I worry that a culture of bluster and sweeping issues aside is prevalent. Did nobody speak up about the obvious mistakes? Are people still truly sticking to the party line of 'a few minor errors' when so many large errors are easy to see?
If this is not the case, and the maps flaws are due to a systemic lack of attention to detail or ground truthing then you have an easier job when it comes to fixing the issues. With a bit of time and some extra work we can have a map that does want it was supposed to do. As it stands even the original purpose of the map, (of helping people find the peat grips so they can be fixed), does not work, let alone the additional layers and uses.
The mistakes so large and so scattergun it is impossible to find a work around when using the map. If every river was mapped as peat, then you could accept that, or if all rocks were deep peat, but as it is just some, you never know what's good and what's not.

There appears to have been no cross referencing with other maps within the
EPM let alone elsewhere in the organisation. Quite why I do not know. The data is there, priority habitats and living England mapping along with the basic maps available showing road networks and waterways could have been used to double check the data, yet they have not been.
The obvious mistake I have found so far are:
Almost all the limestone pavement in England mapped as peat including SSSI areas and the area in the launch video, malham tarn, one of the most studied areas in the country for ecology and geology.
As far as I can see every Dartmoor tor is mapped as peat, along with large areas of rocks and shallow mineral soil surrounding the tors.
Some reservoirs mapped as peat, including Colliford, Cornwall second largest, holding 28,000 mega litres of water.
Shadows of trees, hedges and walls mapped as bare peat across broad sweeps of landscapes to such an extent that it is obvious what time of day the original images were taken
Rivers mapped as peat
China clay works mapped as peat
Known SSSI bogs not mapped as peat
Alluvial river deposits mapped as peat
The vegetation layer mapping known woods (on the tree inventory map) as open bog vegetation
Large areas of semi-improved grassland shown as Eriophorum Bog
Bracken mapped as molinia bog at a vast scale
Roads mapped as peat gullies again and again
Ridge and furrow field systems seen as peat grips along with other archeology mapped as damaged peat
Natural streams and rivers mapped as peat gullies
And

The peat depth and vegetation layers are wrong across so much or the map that it is unusable as a resource.
This list is not exhaustive.
So, in short:
areas that Natural England know are not peat mapped as peat, areas that Natural England know are peat not mapped. Infrastructure like the road network ignored and other open source maps not cross referenced.
The scale of the errors clearly show that any data taken from the EPM cannot be correct up to and including the GHG emissions figure and the restoration potential figures, and any site specific or landscape scale decisions will be made much harder by the maps bad data.
It begs the questions, firstly why is the map still online? A lightweight disclaimer, put up three days after the launch, in no way mitigates the potential harm this map could cause.
Another question about the workplace practices around normal human errors, and how the whole organisation deals with them are also starting to become more pressing as time goes on. If this is allowed to happen what else is equally wildly wrong? Can any of the data coming out of Natural England be trusted?
As I said, 1 am very sorry about all of this, especially after everyone's hard work on the project, but the fact remains that the new England Peat Map is badly wrong and needs to be taken offline.
Thank you for your prompt attention to this matter

Itโ€™s been a whole month since the peat map of England was launched!

Itโ€™s still very wrong
And itโ€™s still online

So Iโ€™ve written a open letter to @naturalengland.bsky.social

I am starting to worry that massive mistakes are just a thing with the whole organisation.

What else is wildly wrong?

Thereโ€™s an invader turning huge swathes of Britain into deserts โ€“ and these dead zones are spreading | George Monbiot Vast areas of land are now dominated by one species โ€“ purple moor-grass โ€“ and good luck with seeing a bird or insect there. How do we revive these habitats, asks Guardian columnist George Monbiot

Whatever happened to nuance?? Dog whistle articles like this only undermine progress towards finding multi-actor consensus on future land management. Hyperbole is no substitute for knowledge.

Note that the numbers in this matrix add up to more than the total number of studies (nโ€‰=โ€‰455), as many studies reported more than one deer species present and more than one effect category.
