Recording Yorkshire's wildlife for over 150 years.

The Yorkshire Naturalists' Union is devoted to studying and recording Yorkshire's flora and fauna.  We are an association of amateur and professional naturalists covering a wide range of aspects of natural history.  We are one of the country's oldest wildlife organisations, having celebrated our 150th anniversary in 2011.


The response to the Covid-19 pandemic is having a major impact on YNU activities and events, and may cause some delays in processing publication orders and new memberships. Please see our Events page for the latest updates.
