Launched by the national trade body, the Property Care Association (PCA), the PCA Plant Risk App helps with the identification of species and provides a hazard rating as well as advice.

The app can help householders understand what is growing on their property, whether it is a cause for concern and what action they should consider.

Invasive non-native plant species can cause a range of issues, from damage to property and impacts on native ecosystems to causing injury.

Japanese Knotweed and certain types of bamboo spread quickly and can cause hard landscape damage, while buddleia is known to colonise masonry, which can make walls and chimneys unstable.

Contact with giant hogweed may produce a skin reaction that is exacerbated by exposure to sunlight and can result in painful blisters.

Himalayan balsam tends to shade out native plants and creates problems around watercourses.

Daniel Docking is the technical manager at the PCA and played a key role in the development of the PCA Plant Risk App.

He said: “Invasive plants are not just about whether a species appears on a list. The risk often depends on the plant, the site and the context in which it is growing.

“While Japanese knotweed is often seen as the main concern, plants such as bamboo, buddleia, and other problematic vegetation such as bramble can also create nuisance, management issues or biosecurity concerns in certain environments.

“There are also species, such as Virginia creeper, that are listed in Schedule 9 of the Wildlife and Countryside Act 1981.

“This means it is the property-owner’s responsibility to ensure they are not allowed to spread into the wild.”

Householders with concerns around unidentified vegetation on or near their property can upload a photograph, ideally including leaves, stems, flowers and overall growth habit.

Once on the PCA Plant Risk App, the picture will help confirm species using the Pl@ntNet database.

A short series of scenario-based questions will follow, which will produce a hazard-rating indication along with advice that sets out what action should be taken, what to avoid and whether specialist help is needed.

In instances where a survey or management plan is strongly recommended, householders can enter their postcode to search for PCA members who specialise in invasive weed control.

Daniel added: “The app is designed to be a useful tool for homeowners, particularly where early identification and practical biosecurity advice could help prevent problems from escalating.

“The earlier problematic plants are recognised, the easier it is to manage spread, reduce disruption and limit potential costs.

“Alongside the app’s learning hub, it also gives users more confidence in identifying issues and applying sensible biosecurity measures.”

Henry Nowak died aged 18 in police custody last December after being stabbed to death by Vickrum  Digwa, of Southampton, who was sentenced to life in jail for the murder on June 1.

Following the sentencing, violent unrest broke out in Southampton on Tuesday night (June 2), resulting in 11 police officers and one police dog being injured.

The Oxfordshire and Thames Valley Civic, Community and Faith Leaders’ Group issued a statement ‘urging calm and restraint’ in the wake of the riots.

The group also commended the ‘dignity and courage’ shown by Henry’s father, Mark Nowak. who appealed for his son’s murder not to be used to sow division.

Bishop Gavin Collins, acting bishop of Oxford, and Imam Monawar Hussain, who co-chair the Oxfordshire and Thames Valley Civic, Community and Faith Leaders Groups, said: “Yesterday’s verdict in the murder of Henry Nowak brings no relief from the terrible pain of a young life taken so brutally.

“Our hearts go out to Henry’s family, and we hold them in our thoughts and prayers with the deepest sympathy.

“We also wish to honour the courage and dignity of Mark Nowak, whose words have reminded the country that this terrible crime must not be used to divide our communities.

“That is a message of real moral clarity at a moment of grief, anger and tension. It deserves to be heard.

“We are deeply concerned by the violence and disorder seen in Southampton overnight.

“No family mourning such a devastating loss should see that grief turned into an excuse for further hatred, fear or unrest. We call for calm, responsibility and restraint on all sides.”

The group said space has to be given for the Independent Office for Police Conduct to investigate the police’s response to the situation, and likewise called for people to not place ‘collective blame’ on the Sikh community.

The faith leaders added: “This is a moment to stand with a grieving family, to reject those who would exploit tragedy for division, and to recommit ourselves to the values of decency, peace and shared responsibility.”

Speaking outside the court after Digwa was sentenced, Mark Nowak, Henry’s father, condemned the police’s treatment of his son as ‘inhumane and degrading’ and said: “We do not want his death to be used to create further division, hatred or tension.

“We want his story to help make our streets safer for everyone .”

Following the riots in Southampton on Tuesday night, Hampshire Police Chief Constable Alexis Boon said some people “clearly arrived intent on causing disorder and trouble” and “while we are forced to deal with those determined to spark fear and division, our finite resources are taken away from those who need it most”.

Oxford Stand Up To Racism has accused Robinson, whose real name is Stephen Yaxley-Lennon, of inciting the ‘awful violent scenes’ in Southampton on Tuesday night (June 2).

The city where 18-year-old Henry Nowak died and where his killer, Vickrum Digwa, lived became a scene of destruction after hundreds descended to smash car windows, hurl bricks and cause eleven officers and a police dog to be injured.

Yaxley-Lennon, who has been jailed multiple times for a variety of offences including when he was imprisoned in October 2024 for contempt of caught, addressed the crowd at the riot.

He said: “I heard someone say this wasn’t about race, this is about race.

“A white boy who done nothing was handcuffed, a murderer in possession of a knife who stabbed someone five times isn’t.”

Oxford Stand Up to Racism is now renewing its call for the Oxford Union to withdraw its invitation for the ‘riot agitator’ to speak on June 17 on the subject of Islam.

He was originally due to speak at the historic debating society on Thursday, May 28 before his appearance was postponed over security concerns and after massive backlash.

Ian McKendrick, a member of the anti-racism group, said: “Despite Henry Nowak’s family clearly requesting that his death should not be used to promote further hatred, Robinson was at the centre of protests in Southampton last night and clearly inciting violence.

“Giving him a televised platform at the Oxford Union legitimises hate and violence, and gives him the opportunity to incite violence to an audience of millions. 

“It does not promote free speech – instead, it promotes fear and intimidation among minoritised communities. 

“Already we have seen Oxford fascists alongside Robinson in Southampton and now mobilising to bring more hate onto Oxford’s streets.”

Members of Raise the Colours: Oxfordshire were called to attend the Southampton protest on Tuesday night, with the leader of the group posting on Facebook to ask followers to join the ‘justice for Henry Nowak’ protest.

Mr McKendrick added: “There is a concerted effort by far right leaders and fascist groups to incite outrage and bring people on to the streets to riot.

“We risk an explosion of violence similar to what we saw around the Southport murders across the UK.

“We’re calling on Oxford to say a clear ‘no’ to this hate and division by protesting against Yaxley-Lennon’s appearance at the Oxford Union.”

Faith and civic leaders of Oxford already wrote to the Oxford Union asking it to rescind the controversial figure’s invitation, and hundreds have signed an open letter calling for the same.
