Blog readers may recall a press release in April 2024 from North Yorkshire Police detailing the execution of a search warrant on an unnamed grouse moor in the Yorkshire Dales National Park, in relation to the illegal persecution of hen harriers (see here).

The very first line of that press release said this:
“On Wednesday, (17 April 2024), a National Harrier Task Force operation was held at an undisclosed location in the Yorkshire Dales“.
That was the first time I’d heard of the ‘National Harrier Task Force’ but I’ve since learned much more about it.
I’ll begin this blog with the reproduction of a press article about the new Taskforce that appeared on a relatively obscure website (CandoFM) in May 2024, then I’ll provide some of my own commentary on this new initiative.
Here’s the press article:
Hen Harrier Task Force Launched To Tackle Illegal Persecution
A new task force has been launched to tackle the illegal persecution of hen harriers, one of the rarest bird of prey species in the UK.
The National Wildlife Crime Unit (NWCU) will use innovative technology and strategic partnerships to detect, deter and disrupt offenders.
Given the rarity of hen harriers, significant resource is invested in their conservation. Satellite tags are fitted to the birds to research their ecology, but these tags have also revealed a concerning amount of illegal killing.
Criminals are intent on targeting this vulnerable species and operate with impunity. There have been no successful prosecutions in recent years despite the efforts of the police and partners.
In response, the launch of the Hen Harrier Task Force, led by Detective Inspector Mark Harrison of the NWCU, represents a pivotal shift in combating wildlife crime.
“The persecution of birds of prey is not just a wildlife issue; it’s serious crime blighting our countryside,” said DI Harrison. “With the launch of the Hen Harrier Task Force, we are determined to disrupt illegal activity and protect this vulnerable species.”
Central to the bird of prey task force’s approach is standardising reporting practices and improving the police response to incidents. Police and partners will work together to ensure resources are deployed swiftly and investigative opportunities are maximised. The task force will also bring together partners to engage with local communities and raise the profile of hen harrier persecution in a unified effort against wildlife crime.
“We cannot tackle this problem alone,” emphasised DI Harrison. “Through proactive partnerships and community engagement, we can strengthen our response and hold perpetrators to account.”
The task force will tackle crimes involving satellite tagged birds of prey. It is data-led, relying on analysis of police data and hotspot mapping. The NWCU has identified crime hot spots where they can focus enforcement efforts, as well as other areas of historic vulnerabilities where they will be seeking to revisit and raise their presence with landowners and land users. These meetings are an opportunity to highlight the issues/risks and identify ways to prevent further incidents from occurring.
Rather than purely focusing on the wildlife aspect of the crime, DI Harrison has tasked his team with taking a holistic view of the criminality and considering all types of offences. Criminals will often steal and destroy the satellite tags to conceal their offending. This could constitute criminal damage, theft and fraud. In the last few years alone, £100,000 worth of satellite tags have been lost in circumstances suspected to be criminal. The apparent use of firearms adds a further level of seriousness to these cases.
Recent examples of this include Anu, a hen harrier in South Yorkshire, which had its satellite tag deliberately cut off by someone possibly using scissors or a knife. Asta, a hen harrier in North Yorkshire, is another example. Although the dead bird was not found, its tag was recovered from a dead crow. The NWCU suspect that fitting the tag to a crow was an attempt to make it look like the hen harrier was still alive and hide the fact that it had been illegally killed. Unfortunately, the crow also died from unknown causes.
The task force’s multifaceted approach includes:
- Improved incident response: Standardised reporting processes enable rapid response to suspicious incidents, ensuring investigative opportunities are maximised.
- Innovative technology: From tracking drones to specialised detection dogs, the task force uses innovative tools to overcome logistical challenges and enhance evidence collection in remote areas.
- Strategic partnerships: The taskforce brings together law enforcement, government agencies, non-governmental organisations, landowners and communities to tackle crime in hotspot areas.
- Community awareness Initiatives: Building on successful models like Operation Owl, the task force seeks to boost public support and encourage vigilance against wildlife crime.
As the task force gains momentum, the team will be dedicated to protecting the UK’s hen harriers. Through collaboration and innovation, it is set to make a lasting impact in the fight against wildlife crime.
About the Hen Harrier Task Force
The Hen Harrier Task Force is an initiative led by the UK National Wildlife Crime Unit and supported by seven police forces (Cumbria, Derbyshire, Durham, Northumbria, North Yorkshire, South Yorkshire and West Yorkshire), DEFRA, the RSPB, National Gamekeepers’ Organisation, British Association for Shooting and Conservation (BASC), The Wildlife Trusts, GWCT, national parks, Country Land and Business Association (CLA), Natural England and The Moorland Association to combat the persecution of hen harriers in the UK. The taskforce aims to detect, deter, and disrupt offenders involved in wildlife crime by using technology and improving partnership working.
ENDS
My initial reaction to this new Taskforce was one of deep cynicism. Given some of the organisations involved, it just looks like yet another pseudo-‘partnership’ that will achieve nothing other than providing a convenient vehicle for DEFRA and its raptor-killing mates within the grouse shooting industry to be able to pretend that they have a zero tolerance approach to the illegal killing of hen harriers because they are all ‘cooperating’ on this Taskforce.
It’s a ploy that’s been utilised many times before and has simply facilitated the continued illegal killing of hen harriers (and other raptor species) without anyone being held to account. The RPPDG (Raptor Persecution Priority Delivery Group) is a prime example – established thirteen years ago in 2011 and has served no useful purpose in terms of tackling raptor persecution, but has provided numerous Government Ministers with an opportunity to appear to be dealing with it. Utter greenwashing.
Those of you with long memories will remember Operation Artemis, another police-led initiative launched twenty years ago in 2004 designed to work in ‘partnership’ with grouse moor owners to tackle the illegal killing of hen harriers. Here’s some info about it from the RSPB’s 2004 Birdcrime Report:
As described by the RSPB, Op Artemis was not well-received by the shooting industry, even resulting in an article published in The Times where the then Chief Executive of the Countryside Alliance, Simon Hart (who later became Chief Whip for the Conservatives) said the police operation was “part of a wider witch-hunt against gamekeepers“.
Operation Artemis stumbled along until 2007 when it was closed down after achieving nothing at all. Here are two more write-ups about it from the RSPB’s Birdcrime Reports in 2006 and 2007 respectively:
Given the complete failure of Operation Artemis to effectively tackle the illegal killing of hen harriers on driven grouse moors, how will this latest initiative, the National Hen Harrier Taskforce, rolled out some 20 years later, be any different?
Well, there are some positive differences.
This time around, the police have the benefit of access to hen harrier satellite-tracking data (provided by Natural England and the RSPB) which has allowed the National Wildlife Crime Unit (NWCU) to identify clear persecution hotspots, i.e. the estates where a disproportionate number of hen harriers are killed / ‘go missing’ in comparison to the rest of the species’ range.
These wildlife crime hotspots have been known for years but this time the NWCU has done its own analysis on the tag data and, even though it has drawn the same conclusions as the RSPB previously, because the hotspots have been identified by the Police it cuts off any opportunity for estate owners to claim that the data are ‘biased’ or ‘fabricated’ simply because the data belonged to the RSPB. In other words, the estate owners/managers can’t so easily dismiss the data as not being credible.
Another major difference this time around is that the police officer leading the Taskforce, Detective Inspector Mark Harrison, is taking a much more strategic approach. He’s not only looking at the offence of killing a hen harrier – he’s looking at the wider, associated offences such as theft (of very expensive satellite tags) and firearms offences. In combination, these crimes amount to a considerable and serious level of offending and can open the door to the police receiving permission to undertake covert tactics, including surveillance and communications monitoring.
To reach that stage, certain steps have be taken first as part of a longer-term strategy. These include police visits to the known hotspot estates (and I understand that there have now been several of these visits in addition to the one in the Yorkshire Dales National Park that was reported in April). If, after these visits, hen harrier persecution continues to be suspected at those hotspots, the police will then be in a position to demonstrate to senior officers that the ‘nicely nicely’ approach has been tried but hasn’t worked and so permission to begin more covert tactics is more likely to be granted.
Permission should be granted just on the basis of suspected firearms offences taking place. If the estate owners / managers / gamekeepers are denying any knowledge of the offences (which is what they’ve been doing for 30+ years) then the police can legitimately conclude that ‘someone’ [apparently unidentified] is running around an estate committing firearms offences and is clearly a threat to the public. As the fundamental role of the police is a duty to protect the public then I can’t see how permission to deploy more covert tactics can legitimately be withheld under these circumstances.
Of course none of these ideas are anything new – we’ve all been saying for years that if estate owners / managers / gamekeepers claim not to know who’s committing firearms offences on their land then there’s a serious concern that armed individuals are running amok and those estate owners / managers / gamekeepers should be fully supportive of the police doing everything they can to find them, just as any of us would if armed criminals were operating on our property.
However, the difference this time is that here we have a senior police officer, with a background specialism in covert surveillance (and thus a deep understanding of what hoops need to be jumped through to get permission for covert ops), prepared to push the envelope and take a more radical approach and actually implement this strategy instead of just talking about it, and I applaud him for that. Whether he’ll be allowed to stay in post for long enough to carry through with this strategy remains to be seen.
Another new initiative with this Hen Harrier Taskforce is a ‘mutual aid agreement’ between a number of police forces. One of the big issues in tackling wildlife crime, and particularly raptor persecution, has always been the availability of a wildlife crime officer to attend the scene promptly to secure evidence. We all know that the police are stretched, budgets are stretched, and it’s not always possible to get an officer on scene quickly – sometimes delays run into days and weeks, which is ridiculous. The mutual aid agreement means that a number of regional police forces have committed to making officers available at short notice for cross-border searches if the local officers can’t attend in time. If that works in practice, it should be good.
Once on scene, the Taskforce is also utilising a wide array of new techniques and equipment to aid any searches. These include the use of drones working within the range of satellite tag signals and the use of specialised detection dogs trained to search for bird corpses, amongst other things.
This all sounds very promising, on paper. Although to be fair, the Taskforce has already started the strategic plan by paying visits to those known persecution hotspots and has given fair warning to the estates about what they can expect if the persecution continues.
The only issue I have with that approach at the moment is that those crime hotspot estates have not been publicly named. The police say this is because they’re trying to build relationships of trust. I say they’re shielding the criminals. I have been told that the decision not to name hotspot estates is ‘not set in stone’ and may be revisited.
Let’s see.
I wish the Taskforce well and, given the current rate of ongoing hen harrier persecution on grouse moors, I’ll expect to see results in the not-too distant future.
