Final answer:
Zone subtypes in order of priority refer to the classification and management of land areas based on environmental conservation, with top priorities being grey zones with no new mining permitted, followed closely by light grey zones under strict control.
Step-by-step explanation:
When determining zone subtypes in order of priority, we reference environmental conservation and land use strategies. For instance, within the context of mining activities, no new mining permits will be issued in the highest priority zones, which are the grey zones. These are followed by light grey zones where strict control is enforced. Priority zones are often defined using criteria such as the presence of rare or endangered species. The Hoyt's Sector Model also relates to zoning by illustrating urban land use patterns, where different zones are designated for residential areas, industry, and other purposes.
By utilizing an environmental tool like Zonation, which assesses the conservation value of land, higher priority zones are identified for protection. This analytic tool aims to optimize habitat protection, with an emphasis on protecting rare and threatened species, by designating high-priority conservation areas. Especially significant are the results showing the advantageous use of a grouped taxonomic approach for identifying priority regions, as opposed to focusing on individual taxonomic groups.
