"So what is Biodiversity anyway?", *Biodiversity or "biological diversity" simply means..."Everything"! - plants, animals and micro-organisms, the genes they contain, and the ecosystems of which they form a part of. The Northern Metropolitan based program, hosted by City of Salisbury aims to conserve indigenous (local native) plants and animals through identifying areas for conservation and/or revegetation and providing education and information to schools, community, industry and government. Some 92% vegetation on the Adelaide Plains cleared since European settlement; thus, any remnants are of extreme importance. The unit also provides information on biodiversity, how to protect remnant vegetation, what to plant locally and how to get involved. This can also include funding projects that conserve remnants, undertaking revegetation or education programs that focus on biodiversity conservation.
