A wildlife observation project is coming to York, giving residents and visitors the chance to record nature in the city alongside locations around the world. The City Nature Challenge is taking place between April 26 and 29.

It is part of a "worldwide bioblitz”, says the University of York, with nearly 600 cities around the world participating this year.

Anyone in the greater York area can contribute by documenting the wild plants and animals they encounter in gardens and parks, in the city or in the countryside, at home or at work.
