Which strategy is encouraged for landscaping to help reduce the need for potable water?

Using drought-resilient native plants is an effective landscaping strategy that significantly reduces the need for potable water. Native plants are adapted to the local climate and soil conditions, which means they typically require less water, fertilizer, and maintenance compared to non-native or high-water demand species. By selecting plants that are well-suited for the area, landscapes can thrive with minimal irrigation, especially in dry periods.

In addition, native plants create sustainable ecosystems by providing habitats for local wildlife and contributing to biodiversity. They often have deep root systems that allow them to access moisture from deeper layers of soil, further increasing their drought resistance. This strategy aligns perfectly with water efficiency goals in LEED certification, as it helps preserve potable water resources while promoting ecological balance.

In contrast, the other options involve practices that either demand more water or can disrupt local ecosystems, thereby countering the objective of water conservation.
