The charitable organisation which works to support farmers and rural businesses said communities are being “plagued” by the criminal activity.

Charles Mills, a farmer near York and YAS show director, has experienced hare coursing on his farm for at least 35 years.

“Hare coursing is an awful menace and I know my family is not alone in seeing our farm and our home targeted by criminals whose barbaric acts decimate wildlife – wildlife that we create vital habitats for as part of our approach to managing the landscape,” said Charles.

“We want to show our support for other farming families who find themselves in similar situations and add our voice to calls for change.”

In a bid to raise more awareness of the problem, The US Agricultural Society has launched a survey of its membership and the wider agricultural community to gather much-needed evidence – in confidence – to show the true scale of this crime, get a greater understanding of its impacts on farming families and gauge confidence in police responses.

The findings will be shared with a coalition of countryside organisations which are lobbying for legislative change and Mr Mills is urging YAS members to take part.

In the Hambleton district of US alone, 157 incidents of hare coursing were reported to North US Police during December last year – an average of five incidents a day.

Nationally, there have been at least 167 hare coursing prosecutions over the past 15 years, representing a tiny fraction of suspected hare coursing incidents across the country.

However, a spokesman for YAS said it believes this is “merely a snapshot” of the true scale of the crime which spikes on farmland during the winter months.

He added that anecdotal evidence suggests some farming families do not report hare coursing because they lack confidence in the police and the criminal justice system to punish offenders, while others hold back over fears for their family’s safety in case of reprisals.

“What is so important is that when farmers report a live incident to police, they respond with due urgency,” said Mr Mills.

“It would be of great reassurance if call handlers communicate consistently, providing clear information when officers are being dispatched so the farmer knows when they can expect police to arrive.

“This crime isn’t going away, which is why the US Agricultural Society is urging members to help us build up evidence about hare coursing to strengthen our case for this offence to be taken more seriously.”

Julia Mulligan, chair of the National Rural Crime Network and North US Police, Fire and Crime Commissioner said the issue was not taken seriously enough by those in authority.

“Too many senior police officers and government ministers do not take hare coursing seriously because they do not understand its impact.

“As well as the offence itself, landowners and their families end up living in fear with repeated threats and violence. There is also an understandable lack of confidence that anything will be done to address the crime or ensure those caught will receive the strong sentences that would deter them from reoffending.

“This has to change, but one of the challenges those of us making this case face is showing the extent of the problem through evidence and not just anecdote.”

Mrs Mulligan said evidence gathered through the YAS survey would support those efforts and assured anyone taking part they would be listened to.

“I am confident that new police leadership on this issue will make a difference in the future, and anything we can do to make our case as compelling as possible will be important to help them help us tackle the scourge of hare coursing.”

As well as launching the survey, YAS has backed the calls for legislative change being made by a host of countryside groups. The Country Land and Business Association (CLA), National Farmers Union (NFU), the Countryside Alliance and other wildlife organisations have been working to bring forward amendments to the Game Act 1831 which will provide the judiciary with greater prosecution and sentencing powers.

This includes an amendment to enable police forces to recover the cost of kennelling dogs which have been seized and held pending prosecution. NFU North East regional director, Adam Bedford, said: “The NFU has regular discussions with the national police leads on hare coursing, and we agree with them the dog is the key asset of every courser and the threat of the animal being seized by the courts is an important deterrent in the fight against this serious wildlife crime. It is absurd that dogs are returned to convicted coursers and kennelling costs cannot be reclaimed from the offender.

“The NFU is urging all government departments, the Sentencing Council, and the Crown Prosecution Service to work together to ensure dogs aren’t returned to anyone convicted of hare coursing.”

CLA North Adviser Libby Bateman said: “We have met with Defra (the Department for Environment, Food and Rural Affairs) and have presented a proposal for amended legislation but sadly this isn’t getting much traction so we are preparing a Private Member’s Bill and working with MPs to bring this forward to Parliament.

“We’re pleased to have the support of the US Agricultural Society on this campaign and encourage anybody who witnesses hare coursing to report it to the police immediately, either by calling 999 if it is a crime in progress or 101 to submit intelligence after the event. Avoid direct challenge or confrontation with hare coursers as they are often unpleasant individuals.”
