The first time I really became aware of the deadening of pinewood afforested ground was on the upper Reelin in the 70s.
This was the very 1st time I had fished the Finn, which itself was far too big to fish that day. So, my friend, an Irish priest, Collum Morris, who had invited me across for a few days, took me up the Reelin.
The environment in the forest floor was absolutely dead, desolate. It stunk of pine needles and spewed acid into the river via the myriad of drainage ditches. The water was sour, full of acid.
I have no issue with Lowland rivers planting low level bushes to shade nursery burns, Highland rivers are doing well enough with none.
However, blanket afforestation is nothing but a sham and trying to paint it as environmentally friendly is a disgraceful deception. People who blindly buy into it need to do a bit more research on the subject and not get sucked into blatant commercial propaganda narrated by some tinpot celebrety who is clearly only in it for the cash.
