Ex IT, ex chemist, ex many things, but beetle ID will probably keep me fully occupied until I die.. But I do love cutting scrub and fixing fences.

The Egrets and the Red Kite returned with continual protection and intervention. Pine Marten will do the same
What interests me is the way the Ravens have repopulated England, with no human support at all. Can we hope that Polecats one manage that same feat.

Not a total surprise. This is a paper that I must read in full

Good work. I'm surveying dung beetles in the UK and cattle dominate everything. I've been surprised as to scarcity of records, considering the ease of spotting their very concentrated habitats

But, we do know of many extinctions. What has been the impact of those? That should be the starting point for assessing possible extinction in the future.
Why should anyone accept a broad-brush assertion of risk with no evidence to back it up?

As examples, what is the impact of losing half of our Leiodes species, or one of the Giraffe subspecies. On the other hand, increasing biodiversity with spp like Alder Leaf Beetle or Rhodendron ponticum is a disaster.
We need evidence rather than slogans.

You could be wrong. They are not convinced by your arguments, but did you offer any evidence? We know that biodiversity is falling, but I have seen no link to increased mortality or ill-health. Doon't blame the economists for the lack of ecological evidence.

I'd guess the scutellum of bug, e.g. Kleidoceris

This is truly linking the landscape. DWT has a ring of sites round this, Middleton Moor links them and allows movement.

This would be a suitable sp to try and recreate. Plenty of closely related extant spp and a near certainty of fitting in to an ecosystem without reserves or zoos.

This ties in with European results showing higher disease levels in bumble bees near honeybee hives.

It is a big claim, but predicated on most of the fossil record being marine. The terrestrial plant records doesn't show the expected gaps.

I have a friend who's take up a job doing Urban Rewilding, so I lent her my copy. I reckon her need was greater than mine, but I do want to get it back, and I do expect that she will buy her own copy.

Places like Priestcliffe Lees above Millers Dale will go either to Hawthorn or Hazel if grazing pressure is removed. The slopes are arguable too steep for cattle. Sheep are the answer, but they aren't allowed in management plans.

But volunteers don't exist un a vacuum. We need staff to organise work parties, trying session to impart skills. I want to seem more volunteers but I don't want their commitment wasted.
