Kate, the Duchess of Cambridge arrives to visit the Urban Nature Project at the Natural History Museum

Kate Middletondressed down to talk up the value of spending time outside on Tuesday.

The Duchess of Cambridge donned a dusty rose jacket and jeans as she headed to the Natural History Museum, just a short drive from her London home of Kensington Palace, to promote the museum’s Urban Nature Project.

Working alongside other museums and wildlife organizations across the U.K., the Project aims to help people reconnect with the natural world and understand the importance of nature in towns and cities as they find practical, everyday ways to protect the planet and support wildlife.

She also offered the children a home-crafted treat of honey from her Norfolk country home of Anmer Hall. “This came specially from my beehive,” she said, according toa report from the event, then asked, “Does it taste like honey from the shops? Does it taste like flowers?”

As she left the museum, Kate fixed an acoustic monitoring device to a cherry tree in the Wildlife Garden. It will record ambient sound to help scientists to investigate patterns of bird, mammal and insect activity in the garden, her office said.

The program is set to be launched later this year and not only dovetails with her and husbandPrince William’s conservation work but also fits in with Kate’s own desire to encourage greater appreciation and love for being outdoors. In recent years, she has invested a lot of energy and time into campaigns to promote the benefits of playing outside and being in nature.
