Growing scientific recognition of the role of private lands for endangered species recovery and the landmark 1981 court decision in Palila v. Hawaii Department of Land and Natural Resources both contributed to making Habitat Conservation Plans/ Incidental Take Permits "a major force for wildlife conservation and a major headache to the development community", wrote Robert D.Thornton in the 1991 Environmental Law article, Searching for Consensus and Predictability: Habitat Conservation Planning under the Endangered Species Act of 1973.

The establishment of the Swiss Confederation is traditionally dated to 1 August 1291, which is celebrated annually as the Swiss National Day. The country has a long history of armed neutrality—it has not been in a state of war internationally since 1815—and did not join the United Nations until 2002. Nevertheless, it pursues an active foreign policy and is frequently involved in peace-building processes around the world. In addition to being the birthplace of the Red Cross, Switzerland is home to numerous international organizations, including the second largest UN office. On the European level, it is a founding member of the European Free Trade Association, but notably it is not part of the European Union, nor the European Economic Area. However the country does participate in the Schengen Area and the EU's single market through a number of bilateral treaties.
