Event details

The 19th century mathematician Augustus De Morgan penned the ditty ‘Big fleas have little fleas upon their backs to bite 'em, and little fleas have lesser fleas, and so, ad infinitum’, highlighting what is a general rule in nature: larger things eat smaller things.

This rule is broken when biodiversity is lost, as is happening more and more in our countryside, with unknown consequences for ecosystems.

Join us and  find out how the biological communities of interacting organisms at Three Hagges Woodmeadow are responding to efforts to recover biodiversity and the complex links between species. 

If you are interested in nature and science, come and explore all this with expert naturalists in a beautiful natural setting.  The guided walk is led by Dave Raffaelli and Dan Carne of the Woodmeadow Trust, and Terry Crawford, a population geneticist, lepidopterist and conchologist.        

Three Hagges Woodmeadow is just six miles south of York. Parking and bike racks are available.  It is easily accessible by bus route 415 York to Selby (Hollicarrs stop just five-minute walk) and Sustrans Bike Route 65 (five-minute cycle). All ages are welcome.
