You are listening to Woodland Walks, a podcast for the Woodland Trust presented by Adam Shaw. We protect and plant trees for people, for wildlife. 

Adam: Well, today I am in Sheffield, known of course as the Steel City renowned for steel production during the 19th century Industrial Revolution. But despite that historical heritage, woodland and green spaces were, and still are, the lungs of the city and seen as vitally important. In fact, it is now, according to Sheffield University, the UK's greenest city, with 250 public parks and over four and a half million trees. That's more trees per person than any other city in Europe and in 2022, Sheffield was named as a Tree City of the World. And I'm meeting Catherine Nuttgens at Endcliffe Park. That's a 15 hectare open space opened in 1887 to commemorate the Jubilee of Queen Victoria. And interestingly, it isn’t in the middle of the countryside; it is two miles from the city centre, the first in a series of connected green spaces, known collectively as Porter Valley Parks, all of which lie along the course of the Porter Brook. Well, although it really is coming to spring, we've been hit with some rather unseasonable snow, and I thought we were going to start with some snow sound effects, but actually this is a very fast-moving river that I'm standing by and I am meeting Catherine. Hello. So, Catherine, just explain a bit about who you are first of all. 

Catherine: OK. Yes, I'm Catherine Nuttgens. I used to be the urban lead for the Woodland Trust, but I've just moved into independent work as an urban forester, an independent urban forester. 

Adam: Fantastic. And you have. We've arranged to meet by this. I was gonna say babbling brook. It's really much more than that, isn't it? So is this the river? The local river. 

Catherine: This is the River Porter, so this is one of five rivers in Sheffield. And it runs all the way up the Porter Valley, which is where we're going to be walking today.<span cla
