The international definitions of wilderness do not apply to most regions in Europe, as there is hardly any pristine wilderness left. In many European regions the rewilding of formerly cultivated Jands is called wilderness as well. The term secondary wilderness is often used for this kind of nature. The inhabitants of Switzerland likewise differentiate between primary wilderness and secondary wilderness. In Switzerland the acceptance of wilderness protection is especially important as the national parks and nature discovery parks that include wilderness areas in their core zones have to be based on a regional initiative and are obliged to be endorsed by the inhabitants of the surrounding communities. Currently there is one nature discovery park in Switzerland: the Wildnispark Zürich with the Sihlwald as core zone. In addition to the Swiss National Park which has existed for 100 years, two new national parks are being planned (Parco Nazionale Locarnese and Park Adula) and will be accepted or rejected within the next few months in a referendum.
