Fast growing hedge for clay soils

[CarobyBlobs]

My neighbour is currently in the process of destroying the very well established hedge at the end of my garden which gives us a lot of privacy and blocks out road noise. Up to them it’s their hedge - but I would like to replace it. My ideal hedge would be:

fast growing
wide leaves for noise cancelling
pet friendly
wildlife friendly
suitable for heavy clay, sometimes waterlogged soil

That bit of garden is not waterlogged now but they’ve also removed a huge tree and are concreting the land so I suspect my marshy garden is about to get a lot wetter. I was going to go for red robin but it’s not really wildlife friendly so I wondered what else I should consider. Things I like like holly are far too slow growing.

also the best place to buy mature plants as cheap as possible would be good. I’m also open to a variety of plants to put in together as long as they meet the requirements.

Sea Buckthorn Check for edibility/toxicity of berries

Please, whatever you choose, do check first that it is happy in coastal conditions. It would be a nuisance to plant a whole hedge then find it didn’t thrive

Also, remember there’s nothing that grows to hedge height and then stops. If you need fast growing, you need to resign yourself to cutting 3 times a year

Berberis; fragrant flowers, berries, evergreen varieties available although spiny. Not sure though if it would thrive in very damp soil although, I believe, it does okay in clay.
