Due to the very diverse, hardly structured nature of the tourism sector and its characteristic weak defined types and diverse transitions between them, an attempt is made to display and categorise the variety of different outward-oriented ecotourism measures related to the support of nature conservation and the maintaining or enhancement of the environment. Furthermore, their implementation in practice and the advantages and benefits that ecotourism companies see in promoting nature conservation are investigated, based on a case study of three Australian lodging facilities.
