Finally!! A group has come together to “standardize” the definition of a sustainable landscape. The American Society of Landscape Architects (ASLA), the Lady Bird Johnson Wildflower Center, the United States Botanic Garden and other organizations have created a partnership called the Sustainable Sites Initiative to develop guidelines and standards for landscape sustainability.
Currently, “sustainable landscape” is a nebulous, mushy concept. What does it mean with regards to water conservation, for example? Or use of native plants? Since it’s never been defined before, “sustainable landscape” is in the eye of the beholder.
