What does sustainable landscaping emphasize in its practices?

• A. Uniformity in Plant Selection
• B. A Whole System Approach
• C. Minimizing Soil Erosion
• D. Exclusive Use of Native Plants

Answer: (B)

Sustainable landscaping emphasizes a whole system approach, which involves considering the interrelationships within the ecosystem. This perspective encourages landscape practitioners to understand how various elements interact, including plants, soil, water, climate, and wildlife. By adopting a whole system approach, practices are designed to enhance biodiversity, improve resource recycling, and create resilient environments.

This method enables landscaping that is not only aesthetically pleasing but also ecologically sound. It focuses on creating landscapes that support local ecosystems, promote water conservation, and improve soil health while often accommodating species beyond just native plants. This integrated outlook is essential for achieving long-term sustainability and responding effectively to environmental challenges.

Other options, while relevant to some aspects of landscaping, do not encompass the comprehensive philosophy of sustainable landscaping as thoroughly as the whole system approach does. For example, while minimizing soil erosion and using native plants can be important components, they do not represent the broader, interconnected strategies that constitute a sustainable landscape design. Similarly, uniformity in plant selection runs counter to promoting biodiversity, which is a critical element of sustainability.
