EPQ research on netting hedgerows

Hi everyone, 

I am currently trying to write an EPQ on the dangers of netting hedgerows and its consequent effects on bird life, and if anyone has any opinions they don't mind me using as sourcing, and if anyone knows of any reputable sources/journals that may be helpful, I would really appreciate it. 

The EPQ is to support the two A-Levels I am taking, to help me to get into University to study marine bird biology, so there's the background for anyone concerned!!!

Hope everyone is well, and all your birds are doing great!!!
