The opening of Mulleborg, which translates to “Fort of Mulle,” had a ripple effect, and today there are more than two hundred forest schools in Sweden and thousands more internationally, sometimes under names like nature kindergarten, nature-based preschool, outdoor school, forest kindergarten, Waldkindergarten, and bush school. Outside of Scandinavia, forest schools are particularly popular in the UK and Germany, but interest is also growing considerably in Japan, Australia, Canada, and the US.
