1. impervious surface

    Constructed surfaces, such as rooftops,sidewalks, roads, and parking lots, covered by impenetrable materials such as asphalt, concrete, brick, and stone. These materials seal surfaces, repel water, and prevent precipitation and melt-water from infiltrating soils. The term impermeable may also be used.

  2. indigenous species

    Refers to plants and animals that have established in New Zealand without the assistance of human beings and without the assistance of vehicles or aircraft. This includes species that are unique to New Zealand as well as those that may be found elsewhere in the world. Use of the words ‘indigenous’ and ‘native’ have the same meaning in these guidelines.

  3. injury prevention through environmental design (ipted)

    IPTED is essentially a way of using design to eliminate hazards that may cause injury to people, often elderly people, within the built environment. IPTED recognises the complementary nature of other design interventions such as CPTED

  4. integrated conservation management

    The management of natural resources, and historical and cultural heritage, and existing or potential activities in a manner which ensures that priorities are clear and that the effects of each activity on others are considered and managed accordingly.

  5. introduced species

    Species other than indigenous species.

  6. invasive species

    Plants that are 1) non-native to the ecosystem under consideration and 2) whose introduction causes or is likely to cause economic or environmental harm by competing for space and resources. The spread of invasive species results in monoculture and hence a decrease in habitat diversity.
