Passiflora - they are only going to cull a certain breed of parakeet, one that is destructive and risky to electical pylon due to the size of their communal nests. they are leaving the colourful london ones alone.
They do need to cull any introduced species that is decimating the indiginous population, cray fish, grey squirrel, I think beavers were here already though.
Damn I wrote this then realise the thread had moved on to something completely different. Codn't believe it!
