What is a key principle in sustainable landscape design?

A key principle in sustainable landscape design is the use of native plants. This approach has several advantages that contribute to the overall health of the ecosystem. Native plants are adapted to the local climate and soil conditions, which means they require less water and maintenance once established. They also provide essential habitat and food sources for local wildlife, including pollinators like bees and butterflies, which are crucial for maintaining biodiversity.

Incorporating native plants encourages ecological balance, reduces the need for chemical fertilizers and pesticides, and promotes soil health. This practice not only conserves resources but also contributes to a landscape that is more resilient to pests and diseases, as native plants are naturally resistant to many local challenges.

In contrast, utilizing exotic plants may introduce species that could be invasive, leading to a decline in local biodiversity. Maximizing chemical fertilizer use can lead to soil degradation and water quality issues due to runoff. Similarly, planting in non-organic soils may not support sustainable practices, as these soils often lack the necessary nutrients and microorganisms that promote healthy plant growth. Thus, selecting native plants aligns with the principles of sustainable landscape design by fostering a self-sustaining environment that thrives with minimal input.
