Wildfires burning across Saddleworth and Marsden Moors are raising serious questions about upland management. 🔥🚨 The National Sheep Association warns removing grazing animals may be increasing fire risk. READ MORE: ow.ly/RSut50YFHzE











@TonyJuniper You will soon be able to read my blog about how the @NaturalEngland managers on Fenns and Whixall Moss NNR have reduced the Curlew population to half of what it was, only 3 years ago, and their electric fences are killing wader chicks, like these Water Rail chicks.






These managers are lying about the Curlew population on Fenns and Whixall Moss NNR, falsely claiming they have increased the Curlew population. I advised them that killing Crows (they killed 191 in 2023), would be counter-productive. I am the only person who has studied the Curlew population in depth, and 99.9% of the time I have been out on the Moss, there has not been a single other person there. Before they started killing Crows, there were about 5-15 Carrion Crows engaged in nest predation behaviour. The same number there are, now. However, until they started killing Crows, most of the Crows were resident, and drove other Crows, and avian nest predators away. I never one saw Ravens, Common Buzzards, Red Kites, Marsh Harriers, Lesser Black-backed gulls etc, engaged in nest predation behaviour. Because they got mobbed by the Crows As there are no territorial Crows left, just non-breeding Crows that come onto the Moss, just for nest predation, they no longer drive these other nest predators away. Meaning I regularly in one day, will see several Ravens, Common Buzzards, Red Kites and Marsh Harriers, and Lesser Black-backed Gulls, engaged in nest predation. Of course the NNR managers never see any of this, because they are hardly ever out on the Moss as they only work office hours. I advised them of all this before I did it. They know I'm a graduate in ecology, and none of them have any ecological knowledge or qualifications. No one disputes that it would be better if predators did not predate Curlew nests. However, killing Crows and Foxes does not necessarily reduce their population density, or predation activity, and can increase it. You don't have to take my word for it, when the RSPB did trial predator control, it made no difference to the Curlew breeding success. I forecast this, before this peer reviewed paper was published. When I sent the NNR mangers this @Natures_Voice research to the managers they failed to respond, or read it. 18 months after I sent the NNR Manager, in charge of the Curlew project this peer reviewed research, I asked him if he'd read it, to discuss it with him, and he admitted he had not read it. When I tried to discuss population ecology with him, he got angry, and clearly did not understand the basics of ecology. This is a vanity project, to make @NaturalEngland and the NNR managers look good. They don't give a flying shit about conservation or Curlews. It is all about appearances. rspb.org.uk/helping-nature…




Why don’t we learn from how niche partitioning structures coexistence among carnivores, and then use that ecological logic to interrogate human–wolf coexistence and the failures of current socio‑political framings self-willed-land.org.uk/articles/niche…
