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.

NEWS - BUTTERFLIES AND MOTHS REPORT - we apologise for the delay in sending this year's report to members and affiliated societies.  This was due to a mistake by the printers.  This has now been sorted out and the copies have been sent by post (5th October).

The latest Yorkshire Bird Report has just been published!  For more information and to order your copy, click here.

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 YNU member Ken Gartside for providing this beautiful photograph of the Herald of Winter fungus, Hygrophorus hypothejus!  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, the interactive Events Map and the YNU Google Calendar - come and join us!
