Plus in many cases agricultural run-off as well, presumably?

Not many smarter-looking birds than a male stonechat!

A chalk stream at sundown.

This chalk stream is much altered by man, shackled by embankments on both sides and overly straightened, deepened and widened. It doesn't operate quite as it should, but still offers refuge for a host of wildlife (and evocative scenes like this).

I work on chalk streams in East Yorkshire. Possible slightly different in their hydrology to your rivers, but over here the main reason for too much siltation is that most of the channel has been widened and deepened, meaning the flow is too slow to keep the gravels 'clean'.

Spend so many years of my life trying to spot otters, in vain. Now, I'm lucky enough to see one (almost at will) almost any time of day, along the same stretch of river.

The caveat is he/she still sometimes disappears without warning, reminding me how elusive they are... #mammals

Also worth highlighting misconceptions about ivy "strangling" trees, and people thinking therefore it needs to be removed.

As a follow-up, I see you also run the mammal and reptile groups. Happy to be added onto those as well.

Hiya! Yes please, that sounds great. Happy for you to add me, thanks 😁

Several times a week as part of my job, I pass this large old beech tree. Over the past couple of years there has been a pair of little owls regularly sat in the hollow, but more recently it's been this barn owl having a snooze in the late afternoon sun.

Treated to one of the UK's true wildlife spectacles. Several thousand pink footed geese flocking in to roost on this area of wet-grassland. The splendid sunset was a bonus.
