City Nature Challenge 2018

Be part of  a global competition to find and identify nature across Greater London.

Why we are doing the project

Join the Challenge! London is competing with more than 60 cities to find and record wildlife between 27 and 30 April. Everyone is welcome to join in - both Londoners and visitors can take part and help showcase the capital's nature.

As part of the challenge, we are hosting a Bioblitz - a 24 hour nature survey - at Hyde Park and Kensington Gardens. Alongside a programme of guided walks and drop-in activities, a team of dedicated scientists, naturalists and volunteers will be there to help you identify your bugs, plants, birds and other species. The information collected from your observations will create valuable records of London's biodiversity. 

Explore the world of bats and birds

As part of the Challenge weekend, we are organising free guided walks through London's Hyde Park and Kensington Gardens. Two of these walks need booking in advance: an evening walk for bats and a daytime walk for birds.

What we want to find out

We want to find out how many different species are living in Hyde Park, to help park managers and scientists to protect it.

City Nature Challenge London is being led by the Museum in partnership with the Royal Parks, University College London, and a host of other organisations that support nature in our city.

How to take part:
