YRN Webinar:

Return of the giants: bluefin tuna to the North Sea

Wednesday, 11th November, 2026, 19.30 to 20.30

Dr Lucy Hawkes will talk about the Atlantic bluefin tuna and other large predators which have recolonised waters off northeast England and how scientific research, such as satellite tagging and heart rate monitoring, can help us to understand and protect these amazing creatures and the marine ecosystem.

Presenter biography: Dr Lucy Hawkes is a physiological ecologist at the University of Exeter, whose work focuses on the costs and drivers of migration in animals using emergent technologies such as satellite telemetry, heart rate logging, accelerometry and metabolic rate measurements. Her work helps in the discovery and understanding of amazing migratory performances by wild animals. She is also a National Geographic Explorer.

YRN Webinar:

Breaking barriers: Restoring natural river processes

Wednesday, 16th December, 2026, 19.30 to 20.30

Sarah Lonsdale, Project Manager for River Enhancement at Yorkshire Dales Rivers Trust (YDRT), joins us to talk about restoring fish passage across Yorkshire’s rivers.
She will highlight how healthy rivers depend on connectivity – fish need to move freely to spawn, forage and find refuge – yet structures like weirs, culverts and sluices routinely block that migration. Sarah will share how YDRT and Great Yorkshire Rivers are working to reconnect rivers across the region, including a major fish barrier removal project recently delivered near Richmond, North Yorkshire.

Presenter biography: Sarah Lonsdale, has worked at Yorkshire Dales Rivers Trust three years as Project Manager for River Enhancement, covering the rivers Nidd and Swale, developing and delivering river restoration projects. She has recently delivered a major fish barrier removal project near Richmond, North Yorkshire. Find out more here: www.ydrt.org.uk

Get out to rewilding sites this winter, meet like-minded people and lend a hand, often by stepping in for the wild herbivores that aren’t there to do the job. Children aged 12 and over are welcome at each event if accompanied by an adult.

Friday 20th November

Times: 11.00 to 15.00

Where: Mill Farm, Redmire, Wensleydale, North Yorkshire

Help with animal surveys and general upkeep at this ten-acre rewilded farm in the Dales. Tasks include surveying and cleaning out bird nest boxes, putting up new ones, fitting guards to young trees (including rare black poplars) and searching for harvest mouse nests. Jobs vary in difficulty, so there’s something for everyone.

Saturday 6th February

Times: 11.00 to 15.00

Where: Eccup Moor Road, Leeds

Join us at this 3.5-acre field of rough grassland, a prime hunting ground for barn owls. We’ll cut self-seeded white poplars (acting as a proxy for bison or other grazers), build dead hedges and check hedge plants, with a campfire to keep us warm. Bring a small hand saw if you have one.

Saturday 6th February

Times: 11.00 to 15.00

Where: Highridge Farm, Summerbridge, Nidderdale, North Yorkshire

Try rewilding coppicing techniques that mimic herbivore damage and clear dominant holly at this 40-acre, largely ancient woodland, letting light back in for natural regeneration. Some tools are provided, but please bring loppers and gloves if you have them.
