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.

Visit our News page to read all the latest news and wildlife sightings from the Yorkshire Naturalists' Union, and follow us on Twitter @ynuorg.

Thanks to Gary Vause for providing this stunning photograph of a kestrel!  To see more photos of Yorkshire wildlife taken by YNU members, please visit our Flickr group.

Our calendar of activities can be found on the Events page of this website and the YNU Google Calendar - come and join us!  The calendar of events for 2017 has now been added to the website and was sent to members with the January edition of The Naturalist
