Ecological Community: a naturally occurring group of plants and/or animals (or other living things such as microbes) that occur in a particular type of habitat.

Threatened Ecological Community: an ecological community that has been recognised in the State and/or under Commonwealth legislation as being under threat of being destroyed or highly modified across much of its range. Threatened is an umbrella term that includes critically endangered, endangered and vulnerable ranked ecological communities.

Critically endangered: facing an extremely high risk of extinction in the wild in the immediate future.

Endangered: not considered to be ‘critically endangered’ but is still facing a very high risk of extinction in the wild in the near future.

Vulnerable: not considered to be ‘critically endangered’ or ‘endangered’ but is still facing a high risk of extinction in the wild in the medium-term future.

Declared rare flora: plant taxa which have been adequately searched for and are deemed to be in the wild either rare, in danger of extinction, or otherwise in need of special protection.

Environmentally Sensitive Area: areas declared in the Environmental Protection (Environmentally Sensitive Areas) Notice 2005 (Government of Western Australia, 2005) including but not limited to conservation category wetlands, vegetation containing rare flora, threatened ecological communities and Bush Forever sites.

Phytophthora dieback: refers to the introduced plant pathogen Phytophthora cinnamomi that infects the roots of over 2300 susceptible native plant species, killing the individual plant and altering the composition of the plant community that they are a part of.

Habitat: the place where an organism or a group of organisms normally lives.

Holocene: the name given to the time period which includes the last 10,000 years.

Invertebrate: an animal without a back-bone.

Microbialite: structures formed by microbial communities through the precipitation of calcium carbonate (limestone). Two types of microbialite include thrombolites and stromatolites.

Natural Resource Management: the ecologically sustainable management of the land, water, air and biodiversity resources for the benefit of existing and future generations, and for the maintenance of life.

Obligate seeders: plants that regenerate from seed almost exclusively after fire.

Priority flora: plant taxa that are under consideration as threatened flora but need further survey to adequately determine their status.

Swan Coastal Plain: a 30 km wide strip on the Indian Ocean coast directly west of the Darling Scarp uplands running from Cape Naturaliste in the south to north of Perth.

Thrombolite: a calcareous mound built up of layers of lime-secreting microbes and sediment. A form of stromatolite but with a clotted internal structure rather than a layered structure.
