I have to say that I am getting more than a little fed up at all of this "red squirrels were being wiped out by grey squirrels" nonsense. Back in March I referred to the question about the red squirrel https://exoticanimalsregister.blogspot.com/2021/03/uk-and-exotic-species-human-aided.html
People are still -still- shooting and trapping red squirrels as "vermin" -especially where forestry that is seen as a financial investment is concerned. Talking to someone the other day I was told the owner of a large country estate had been out a couple weeks back shooting red squirrels, rabbits and anything else he and his associates could find. The idea and practice of the medieval fiefdom where the lord and master can do whatever he wants still exists in the UK. Policem, RSPCA et al: "private property we can't go onto the land there" -even when they know wildlife crimes are being committed.
So the idea that we had a great red squirrel population before the grey squirrel got here is rot. The grey adapts to a situation while the red seems stuck in a rut of sorts. The new forestry planted will be looked at as a financial investment not just to clean up our air. Red squirrels damage trees (barking etc) then watch them disappear. Who knows they vanish and if they find out it is a case of "Oh, those bloody grey squirrels" and everyone sits back in the ignorance they have been fed and repeat "Bloody grey squirrels. Vermin"
Also worth pointing out that the red squirrels today are NOT our original squirrels who shared the same fate as our Old foxes and were replaced by imported squirrels to continue the 'sport'.
Face it; for a nation of "animal lovers" we still allow fox-hunting, badger baiting and so much more and the squirrel is just one victim in all of this. A well financed independent UK wide wildlife agency is needed and when I write independent I mean independent of the government nationally or locally and with powers to enforce protective legislation on private and common land.

Research shows planned expansion of conifer woodlands across the UK could have unintended consequences
Conifer plantations, which are being expanded around the UK to combat the climate crisis and foster biodiversity, are in danger of hurting one of the key species they were thought to protect: red squirrels.
The threatened red squirrels, driven to near-extinction over most of the UK by grey squirrel incursion, were thought to thrive in conifer habitats as the food sources in such forests tend to be limited to small seeded cones, which red squirrels are better at exploiting than the more generalist grey squirrels. That should mean conifer plantations prove better for red squirrels than greys.
But new research upends that perception by highlighting the role of pine martens. These native predators were until recently, like the red squirrel, in short supply. Recovery in their numbers has shown that pine martens are generally good for red squirrel populations, at least in native broadleaf woodlands, because they suppress the numbers of grey squirrels.
The research, published in Proceedings of the Royal Society B, found this was not true in conifer plantations, where pine martens lack diverse sources of food and prey on red squirrels instead, turning them from a protector to a threat.
To conduct the research, scientists from Queen’s University Belfast and the University of St Andrews, with Ulster Wildlife and the help of citizen scientists, used camera traps to survey more than 700 sites across Northern Ireland over a five-year period, looking for red squirrels, grey squirrels and pine martens.
Dr Joshua Twining, lead author of the research, from Queen’s University in Belfast, explained the findings: “In natural woodland, there are diverse amounts of prey, and lots of refuges for squirrels, so red squirrels don’t get predated all that much. But in conifer plantations, where a single species is planted and of uniform age there is very little biodiversity or alternate prey, and an absence of refuges, so pine martens will eat red squirrels to survive here.”
He said the research suggested that woodland managers should reconsider whether conifer plantations should be preferred over native broadleaf trees. “We need to adapt our strategy: if we keep planting conifer plantations, as opposed to native woodland, this saviour of the red squirrel may cause its decline in certain locations,” he warned. About three-quarters of the forested area of the UK and Ireland is made up of non-native timber plantations, of species such as the sitka spruce, according to the researchers.
Conifer plantations were already a cause of concern to ecologists, as they tend to be monocultures, are often harvested after a few decades, and may provide less diversity than native broadleaf species. But government planting schemes in the UK and Ireland have tended to favour conifers, which are easier to plant and harvest.
A spokesperson for the UK Department for Environment, Food and Rural Affairs said: “We are committed to taking action to recover our threatened native species in England, such as the red squirrel. The planting of coniferous trees in England is at a low level, with our Nature for Climate Fund focusing on the establishment of native broadleaf woodlands at a large scale. Alongside our England Trees Action Plan, this will support the recovery of native red squirrel populations across the country.”
