networks. Both member nations must endorse the park. The management bodies in each nation must collaborate to establish a single set of activities and strategies for the entire park. They can appoint either two collaborating managements or one management. The certified transnational geoparks are: Geopark Karawanken Marble Arch Caves Global Geopark Novohrad – Nógrád Geopark Muscau Arch / Łuk Mużakowa UNESCO Global Geopark Regional geoparks A regional geopark is a member of an independent network of geoparks that has agreed with UNESCO to provide candidates for the global network. All members of the regional network are a priori members of a national geopark network. They are also members of the global network if they are certified for it. A regional geopark would not be a global geopark if it has not yet been certified as such or its certification has lapsed and it has applied for recertification (Yellow Card status). A region is more than one country. A current list of accepted regions is: African Geoparks Network Asia Pacific Geoparks Network (APGN) European Geoparks Network (EGN) Latin America and the Caribbean Geoparks Network (LACGN) Acting regional geopark Canada has some geoparks. The most logical regional classification for these might have been the "North American Regional Geopark Network," following a proposed continental tradition for geopark regions. However, the United States does not have any geoparks, and Mexico is covered under Latin America. There are no other nations in North America that can be combined into a region. The United States and Israel resigned from UNESCO in 2018 because they believed that UNESCO is anti-Israel. Canadian geoparks according to the rules must belong to a regional network before they can apply for global status, but there is none, and may not be any in the foreseeable future. UNESCO therefore treating Canada as a special case allows the national geoparks network, the Canadian Geoparks Network, to give global and green card certification. A regionalization based strictly on continents did not turn out to be practical for other regions also. UNESCO Global Geoparks A global geopark is one that has been certified to the fullest extent, and is therefore a member of UNESCO's global network of geoparks. It is per se also a member of a regional geopark network and also a member of a national geopark network, if its nation has one, or a transnational geopark. A certification is good for four years,
