2 What is Biodiversity? Biodiversity refers to the variety of life forms; the different plants, animals and micro-organisms, the genes they contain and the ecosystems they form. It is usually considered in terms of genetic diversity, species diversity and ecosystem diversity (Commonwealth of Australia, 1996). The conservation of ecosystem diversity is the most strategic way to conserve all levels of biodiversity (genetic, species and ecosystem) and aims to prevent these elements of biodiversity reaching the point where they become threatened. For example, by conserving an area of bushland in good condition that includes trees, shrubs and groundcovers, the number of plant species conserved in that community is increased and the number of animal species that can be supported is also increased by providing a greater number of food sources and habitat types. Melloway Reserve – Photo taken by Eleanor Bennett A method used to describe ecosystem diversity is the Ecological Community concept. An Ecological Community is “a naturally occurring biological assemblage that occurs in a particular type of habitat” (English and Blyth, 1997). In the Perth Metropolitan Region, the most common way to interpret and quantify ecological communities based on area is to use the vegetation complexes defined and mapped by Heddle et al (1980) and Mattiske and Havel (1998). These vegetation complexes are based on the patterning of vegetation at a regional scale reflected by the underlying key determining factors of landform, soil and climate. Vegetation complexes have therefore been used to develop some of the biodiversity targets found in Part B. 3 Why is Biodiversity Conservation Important? Thysanotus multiflora (Fringed Lily). Photo taken by Linda Kirchner Southwest Western Australia has been recognised globally as one of the planet’s 34 major biodiversity hotspots, and is the only one in Australia. To qualify as a hotspot, a region must meet two strict criteria; it must contain at least 1,500 species of higher order plants as endemics, and it has to have lost at least 70% of its original habitat (Southwest Australia Ecoregion Initiative, 2006). Southwest Western Australia is therefore a significant part of the planet’s natural heritage Local Biodiversity Strategy Page 15
