Most rural hedgerows are protected and cannot be removed without planning permission. Even then, the hedge needs to be less than 30 years old. Full details: https://www.gov.uk/guidance/countryside-hedgerows-regulation-and-management

If you believe a hedgerow is being illegally removed, you should report it to the police. You can do this via their online crime reporting system: https://www.westmercia.police.uk/advice/advice-and-information/wc/wildlife-crime/  or call 101. If the removal is in progress you should call 999.

The concern around cutting hedgerows relates to the disturbance of wild birds. It is illegal to intentionally disturb, harm or kill wild birds and it is illegal to intentionally or recklessly disturb or damage a nest. Natural England says: “the main bird breeding season is recognised as being between 1 March and 31 July. Therefore the risk of committing any of the above offences is increased between these dates. It is recommended that if you undertake any work within these dates you should check the hedge for any signs of breeding activity first (such as observation from a distance using binoculars and direct searching of the hedge for nests).” Full details: https://hedgelink.org.uk/cms/cms_content/files/489_hedges_and_the_law_updated_april_2015.pdf

If the disturbance is in progress you should call 999.
