UK zoo released 'thousands of giant spiders' into wild

Glasgow Times25-07-2025
For that matter, have you seen one?
Well, just last year, Chester Zoo posted on their Facebook page: "Ten years ago we helped release THOUSANDS of GIANT spiders back into the UK!
"The fen raft spiders were bred right here at the zoo, and we're super happy to report there are now more than 10,000 breeding females... and they've just had the biggest mating season on record!
"You can't miss them, they grow to be the size of your hand! Honestly, you're so welcome".
It's fair to say that people in the comments were...less than thrilled, at the time.
"I love you Chester Zoo & very well done and all that, everyone does an amazing job - but honestly....could you not have kept these to yourselves," said one.
Someone else commented: "I need to know where they live so I can make sure I never get within 50 miles of one".
Another user said: "As much as I'm not the biggest fan of spiders, they have their rightful place within an ecosystem.
"Thank you Chester Zoo, for making sure you protect and look out for the species that are not always as appealing to the human eye.
"Every living thing has its place and each little soul matters."
Whilst another replied: "You guys do such great work but this is something I feel like I could have died happily not knowing about to be honest."
But the news did not seem to terrify everyone, with one individual saying: "Well done. We need to get natural beings to thrive again.
"Too many of the human species kill anything they see they don't like unable to realise that their species relies on all others for their existence. Spiders have their important place in the order of our world. Bx".

Are fen raft spiders dangerous?
The spider was on the verge of extinction in the UK in 2010 but has thankfully made a comeback thanks to the efforts of the (Royal Society for the Protection of Birds) RSPB and now Chester Zoo.
The Fen Raft Spider's diet includes other spiders, damselflies, dragonfly larvae and even fish and tadpoles.
They are easiest to spot in grazing marsh ditches from June to September.
The spiders are not venomous but are semi-aquatic and can run across the water's surface to capture their prey.

Peak District hen harrier chicks given protective satellite tags

Two hen harriers born in the Peak District have been fitted with satellite tags in a bid to protect them from National Trust said the tags would provide "vital information" about the birds' behaviour and show insights into roosting, breeding, foraging sites and help gather evidence in "the fight against criminal activity" against the bird of comes after a record numbers of the species, one of the rarest in the UK, have been killed or have gone missing in suspicious circumstances over the past five Thomas, head of investigations at the Royal Society for the Protection of Birds (RSPB), described satellite tagging as a "game changer" for conservation. The tagged chicks are part of a brood of three from the same nest who have successfully are the offspring of the adult birds which featured on the BBC's Springwatch earlier this Best, general manager in the Peak District at the National Trust, said it had been "wonderful" to see successful nests on the land it cared for."We've been restoring peatland and improving wetlands and grasslands to support a diverse mix of species," said Mr Best."Seeing these birds thrive is a good indicator that our work is making a difference."Mr Best did warn that despite legal protections, hen harriers continued to face threats from illegal persecution."We're working closely with the police, statutory agencies, and conservation groups to tackle this issue," he said."Tagging is one way we can monitor the birds and gather evidence to support investigations." 'Better future' Each year in England, about 30 chicks are fitted with these tags, according to the trust, which added that there are only 30 to 40 breeding pairs of hen harriers in the tagged hen harrier - fitted with a satellite device in 2022 - has been tracked flying more than 550 miles (885km) between Cornwall and the Peak District, returning to the moorland where it fledged after stopping in Wales."Satellite tagging of hen harriers has been a game changer," Mr Thomas of the RSPB added. "It tells us what habitats the birds are using and informs us of the place and reason for any mortality. "For a persecuted species this is vital, to inform police investigations, to document associated land uses and to lobby for policy outcomes that aim to provide a better future."RSPB officers fitted the tags about a month ago, thanks to funding from the National Trust and the Peak District National Park Authority.
