‘Guerrilla gardener’ in Harrogate woods falls foul of council’s conservation policyDon’t let Japanese knotweed scupper your house purchase, property expert warns‘Asian hornet’ spotted in Harrogate garden

A suspected Asian hornet has been spotted in a garden in Harrogate today.

Andy Johnson believes he spotted one of the invasive insects on the fence outside his garden in the Hookstone area of town.

He told the Stray Ferret:

“I didn’t manage to get a camera in time to take a photo, but I had a look online afterwards.

“I put two pictures up on Facebook and someone I know said one was a European hornet and the second was an Asian hornet.

“The one that’s more akin to what I saw is the Asian one, with slightly orangey wings. If it was an identity parade, I would say it’s the second one.”

The invasive species is a threat to native honey bees, which is why Defra asks sightings to be reported via its website – and even set up an app for reporting sightings in 2017.

Its website said the hornets pose “no greater risk to human health than a bee” but they were a threat to British honey bees, which was the reason any sightings needed to be reported.

Since 2016, there have been 22 confirmed sightings in the UK, including 12 nests which have been destroyed. One of the sightings in 2018 was in Hull, but the rest are mostly closer to the south coast and commonly in September and October.

Mr Johnson said he had reported his sighting to the Harrogate and Ripon Beekeepers Association and was awaiting a call back. He added:

“My neighbour saw it first and said, ‘what’s that?’

“She is a retired doctor who has lived here for many years. She’s into gardening and she knows much more about identifying insects and things than I do, so if it’s not something she recognises then it must be unusual.”

He added he wanted people to be aware that the insects could have migrated to the Harrogate area so if they spotted one, they would know to take a photograph and report it.

Mites to be released to tackle invasive plant at Harrogate nature reserve

Mites will be released into Rossett Nature Reserve in Harrogate in a bid to tackle the growth of an invasive species of water weed.

The crassula mites attack Crassula helmsii — also known as New Zealand pygmyweed — an invasive non-native species which is causing problems for the wastewater network.

It grows on the arms of filter beds, stopping them functioning properly, and can become dominant in wetland areas which then poses a threat to the breeding habits of native species, including the protected great crested newts.

The release of the mites is a joint trial project between Yorkshire Water, Harrogate Borough Council, the Centre of Agriculture and Bioscience International and Yorkshire Wildlife Trust.

Dr Steph Bradbeer, invasive species and biosecurity advisor at Yorkshire Water, said:

“Invasive non-native species pose a very real risk to Yorkshire’s environment and wildlife. They can also impact on our ability to treat and distribute water to homes and return wastewater safely to the environment.

“Crassula is one such species and we hope this trial will provide an environmentally friendly way of tackling it in the environment and at our wastewater treatment works.”

The mites have been quarantined and tested extensively to ensure they will only tackle Crassula helmsii and will not attack other species of Crassula, such as stonecrops, which are attractive plants that brighten up stone surfaces in the summer.

The announcement of the trial coincides with Invasive Non-native Species Week, which began on Monday and aims to raise awareness of and prevent the spread of invasive plants.

Invasive non-native species not only impact on the environment, but also have a large economic impact, costing the UK economy an estimated £1.8 billion per year.

Councillor Andy Paraskos, Harrogate Borough Council’s cabinet member for environment, waste reduction and recycling, said:

“This is a new approach for us in the Harrogate district and we welcome this opportunity to work with Yorkshire Water and Yorkshire Wildlife Trust – and of course the Crassula mites – to use a practical solution to help tackle this non-native weed at Rossett Nature Reserve.”
