Hobo u20. Don't get the fancy Bluetooth version with paired barometric top unit... They are not watertight which is a key feature for a water table logger

Full results in prep- just wanted to show off some of the more dramatically successful pools!

We don't have a picarro but have had trouble with over heating in summer... check internal temp would be my first idea

I shall remember this argument next time R2 tells me I have to cite all the Heinemeyer papers otherwise I'm being biased when I try to get a perspective piece published :)

I'm not questioning the paleo evidence but you seem to be saying because it has cycled between Heather and sphagnum in the past, recent management has done nothing. This doesn't follow.

But the 'myth' you're busting is "2. Fire and heather dominance are a result of recent management changes". Heather being dominant on a site a few thousand years ago doesn't change the fact many moors weren't heather 100 years ago but are now because of management with that stated goal.

If you think a signficant result from a large, multi-site study needs to be ignored due to confounding factors, that's probably the sort of thing to put in your paper rather than presenting all the evidence in one direction and none of the evidence in the other?

I wouldn't rely on them completely but C.E. Moss' maps often show moors having a small heather fringe in 1910 which are now 100% heather under burn management. I didn't realise anyone questioned that heather cover has increased given it was the goal of management from that period onwards

Weird as the conclusion states the importance of not using one site and assuming others will be the same... would have thought a national, 95 site study is the sort of thing you'd treat with more weight than the single site studies you've cited (Lee, Miligan) that show increase in sphagnum

Point 3 provides citations for sphagnum increasing with burning but fails to mention the massive 2,013 plot, 95 site study that showed at a national scale, burning decreases sphagnum. No critique of that paper, just seem to be ignoring it?

Prescribed burning, atmospheric pollution and grazing effects on peatland vegetation composition
Burning, grazing and atmospheric pollution are associated with peatland vegetation composition and cover of key species, including Sphagnum. We suggest that, to promote cover of peat-forming species,...
