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.
