Temperate rainforest has become a fashionable campaigning cause that overshadows the existence & potential for nature of other woodland types in Britain, not least the Ancient Woodland Indicator plant diversity of woodlands with high ecological integrity

Turnstone turning stones this morning amongst the rocks below the point of extension of West Pier, Whitby

Turnstone turning stones this morning amongst the rocks below the point of extension of West Pier, Whitby
Went to see the turnstones this morning, but none there. Small bird flew in amongst the rocks just as I was leaving. Once this purple sandpiper (Calidris maritima) realised I wasn’t moving, it got on with looking for food. Fortunately, the yapping dog was oblivious to its presence

A common starfish (Asterias rubens) is slow moving, but that is still faster than its relatively immobile prey of marine molluscs like mussels, as well as barnacles, sea snails and sea urchins

The sensitivity of turnstones to human disturbance on the NE coast varies, their Flight Initiation Distance being shorter in disturbed areas. These turnstones near the harbour wall at Whitby show a degree of habituation to disturbance, or maybe they just want their photo taken

"Are you collecting fungi too?" asked a lady with a big basket. "No, I'm here for a walk" was my reply. Here are some fungi I "collected" with my camera in the birch woodland on Ugglebarnby Moor

Homo sapiens hunted much megafauna to extinction... then domestication and agriculture/livestock went on to cause yet more harm:
"Over the last 10,000 years or so, humans have overseen the wholesale replacement of native mammal communities with a very limited set of domesticated species."
"Over the last 10,000 years or so, humans have overseen the wholesale replacement of native mammal communities with a very limited set of domesticated species."
Fossil evidence from six continents indicates that human agriculture and livestock have fundamentally altered global mammal communities, disrupting natural patterns established during the Ice Age. doi.org/g95dzg
How humans reshaped the animal world: Research traces 50,000 years of change
New fossil research shows how human impacts, particularly through the rise of agriculture and livestock, have disrupted natural mammal communities as profoundly as the Ice Age extinctions.

This shows the challenge of livestock as 'wild animals'. Another question is if it is appropriate or necessary to maintain livestock - however wild - on St. Kilda now that the people are gone? Deep questions really, about what authenticity means in nature. www.bbc.co.uk/news/article...
Fresh call from Uist vets for controls on remote St Kilda's sheep
Two vets say numbers of Soay sheep need to be reduced to prevent animals from starving in winter.

Two weeks of choking on smoke from moorland fires ~9 miles away from me. The reason why is our national protected area system that fetishizes cultural landscapes & demands they are held in stasis against natural processes. Here is the habitat map of NYM SSSI where the fire is - endless heathland🧵
