Redwood trees at Jedediah Smith Redwoods State Park, California, USA

March 21 is the International Day of Forests, which highlights the important role that trees and their forest ecosystems play in creating a healthy environment. Here at the Jedediah Smith Redwoods State Park in California, United States, the giant coastal redwoods – plus a variety of other trees, shrubs, bushes, flowers, ferns, mosses and lichens – provide a haven for many creatures, even the small and slimy. This is banana slug territory and visitors are likely to encounter the bright yellow slug – the largest slug in North America – as they journey through the park.
