and their surrounding environment. It is also a set of both empirical observations and information emphasizing the aspects of animals and their behavior, and habitat, and the physical characteristics of species, and animal abundance. This is most useful for risk assessment and management which provides nations with opportunity to influence resource management. However, if a nation does not act, then the state may act on its own interests. This type of "empirical knowledge consists of a set of generalized observations conducted over a long period of time and reinforced by accounts of other TEK holders." Management systems The second face refers to the ethical and sustainable use of resources in regards to management systems. This is achieved through strategic planning to ensure resource conservation. More specifically this face involves dealing with pest management, resource conversion, multiple cropping patterns, and methods for estimating the state of resources. It also focuses on resource management and how it adapts to local environments. Past and current uses The third face refers to the time dimension of TEK, focusing on past and current uses of the environment transmitted through oral history, such as land use, settlement, occupancy, and harvest levels. Specifically medicinal plants and historical sites are great concerns. Oral history is used to transmit cultural heritage generation to generation, and contributes to a sense of family and community. Ethics and values The fourth face refers to value statements and connections between the belief system and the organization of facts. In regards to TEK it refers to environmental ethics that keeps exploitative abilities in check. This face also refers to the expression of values concerning the relationship with the habitats of species and their surrounding environment - the human-relationship environment. Culture and identity The fifth face refers to the role of language and images of the past giving life to culture. The relationship between Aboriginals (original inhabitants) and their environment is vital to sustaining the cultural components that define them. This face reflects the stories, values, and social relations that reside in places as contributing to the survival, reproduction, and evolution of aboriginal cultures, and identities. It also stresses "the restorative benefits of cultural landscapes as places for renewal" Cosmology The sixth face is a culturally based cosmology that is the foundation of the other aspects.
