biodiversity

also called biological diversity; the relative number of species, diverse in form and function, at the genetic, organism, community, and ecosystem level. Loss of biodiversity − one of the global environmnatel problems − reduces an ecosystem's ability to recover from natural or man-induced disruption.

EU legislation: protection of nature and biodiversity

increased urbanisation and the spread of human infrastructures, over-exploitation of natural resources, pollution are the main factors, which highly damage biodiversity. Introduction of exotic species into the native ecosystems pose also a hazard. As a result, 42% of mammals, 15% of birds and 52% of freshwater fish across Europe are under threat. In addition, nearly 1000 plant species are at serious risk or on the verge of disappearing completely. In order to safeguard biodiversity and combat the extinction of animal and plant species, the European Union has set up a vast network of protected sites (the Natura 2000 network) and made the protection of biodiversity one of the key objectives of the Sixth Environment Action Programme.

nature and biodiversity conservation

ecologists, naturalists, and other scientists collectively research and address issues pertaining to global declines in biodiversity. The conservation ethic advocates management of natural resources for the purpose of sustaining biodiversity in species, ecosystems, the evolutionary process, and human culture and society.

Conservation biology is reforming around strategic plans that include principles, guidelines, and tools for the purpose of protecting biodiversity. Conservation biology is crisis–oriented and multi–disciplinary, including ecology, social organization, education, and other disciplines outside of biology.

Preserving biodiversity is a global priority in strategic conservation plans that are designed to engage public policy and concerns affecting local, regional and global scales of communities, ecosystems, and cultures.

Action plans identify ways of sustaining human well-being, employing natural capital, market capital, and ecosystem services.
