A forest kindergarten is a type of preschool education for children between the ages of three and six that is held almost exclusively outdoors. Whatever the weather, children are encouraged to play, explore and learn in a forest or natural environment. The adult supervision is meant to assist rather than lead. It is also known as (in German), outdoor nursery, nature kindergarten, or nature preschool.
A forest kindergarten can be described as a kindergarten "without a ceiling or walls". The daycare staff and children spend their time outdoors, typically in a forest. A distinctive feature of forest kindergartens is the emphasis on play with toys that are fashioned out of objects that can be found in nature, rather than commercial toys. Despite these differences, forest kindergartens are meant to fulfill the same basic purpose as other nurseries, namely, to care for, stimulate, and educate young children.
Each forest kindergarten is different, partly because the organisations are independently minded. But typical activities and goals may include:
Forest kindergartens operate mainly in woodland, although some other sites can be equally inspiring, for example beaches and meadows. There should be a building where children can shelter from extreme weather. They may also spend a small part of each day indoors, although that is more likely to be for administrative and organisational reasons, such as to provide a known location where parents can deliver and collect their children. If the woodland is too far away to walk, a vehicle might reluctantly be used for transport.
Children are encouraged to dress for the weather, with waterproof clothes and warm layers, according to the climate.
There are some forest schools that take children of various ages to woodland less frequently, and with a stronger focus on environmental topics themselves. For example, the "Woods for Learning" strategy of the British Forestry Commission proposes "regular" access, for example once a week for eight weeks.
In rural areas, and historical times, access to nature has not been a problem. Over the last century, with increasing urbanisation and "nature deficit disorder", there have been many changes in stance on outdoor education. In 1914, the socialist political activists Rachel and Margaret McMillan set up an "open-air nursery" but little is known of the details, except for an improvement in child health.
