ATC Engineering Technology 2 Sustainability Practice Test

A key characteristic of sustainable landscape design is efficient water use and the incorporation of native plants. This approach emphasizes environmental harmony and sustainability by utilizing plants that are well-adapted to the local climate and soil conditions. Native plants typically require less water, are more resilient to pests, and support local wildlife, thus reducing the need for chemical fertilizers and pesticides.

By focusing on efficient water use, sustainable landscape design minimizes the demand on local water resources, which is crucial, especially in areas that may experience drought or water scarcity. This practice encourages the development of landscapes that are not only beautiful but also environmentally responsible, promoting biodiversity and fostering healthier ecosystems.

The other options do not align with the principles of sustainable landscape design. The use of exotic plants for aesthetics can lead to ecological imbalances and higher maintenance needs, while high maintenance resource requirements contradict sustainability by requiring more water, labor, and often synthetic chemicals. Furthermore, restricting sustainable practices to urban areas overlooks the potential benefits that these principles could offer in rural or suburban landscapes.
