It was all smiles at Gillespie Park on Sunday as more than 500 people joined the great and the good of Islington politics to celebrate its 20th year as a nature reserve.

But it was a very different story three decades ago, when the park – now an oasis – was at risk of being turned into flats and Jeremy Corbyn took the fight to save it all the way to Parliament.

Activities on Sunday ranged from live music to pond-dipping, with a penalty shoot-out led by the Arsenal foundation and bee and butterfly crafts run by the Octopus Wildspaces Project meaning there was something for everyone.

There were speeches from the Friends of Gillespie Park, MP Mr Corbyn, council leader Cllr Richard Watts and new mayor Cllr Kat Fletcher. All told of their pride at how the area has developed since being designated a park in the mid-’80s its eventual designation as a nature reserve in 1996.

Speaking about his experiences in the original campaign to save the park from being turned into housing, Mr Corbyn told how he had to march cuttings of a rare grass from the park into Parliament just to have his voice heard.

Sally Oldfield, nature conservation manager at the Islington Ecology Centre, said she was “really pleased” with how the event ran.

“I think local nature reserves in general are very important, especially in somewhere like Islington, because it’s a very urban place,” she said

“It’s great that people can come to a place like this that isn’t just swings and a slide.

“It’s different, it’s natural – it’s a place where wildlife can thrive.”

She added: “It’s a hidden gem, a little oasis in the heart of Islington.”

Originally given to the council on a temporary basis, the park was due to be sold for housing before a campaign by residents and councillors saw it designated Islington’s first nature reserve in 1996.

And Ms Oldfield feels sites like this are vital for the borough, which has less green space per head of the population than anywhere else in the UK.

“Sunday was all about recognising the value to the community and the history of the site,” she said.

“It’s a very calm, peaceful, beautiful place to be, and that’s important in a community like this.”
