Book Review: The Authentic Garden: Naturalistic and Contemporary Landscape Design

Quoted from The Dirt, ASLA Blog at http://dirt.asla.org/
Artfully Naturalistic Gardens
“Those familiar with naturalistic planting design, an approach that appears seemingly natural but is actually constructed, will undoubtedly recognize the names of William Robertson and Gertrude Jekyll who pioneered the style in the late-1800s. While the approach has remained popular over the last 125 years, The Authentic Garden delves into how it has evolved from the 1800s to present day. Over the centuries, two design principles came to the forefront: first, create multi-seasonal gardens and, second, make them ecological. These principles, according to the authors, have helped to ensure the naturalistic approach endures as designers adapt English traditions to their own climates.
One of the most compelling examples of this evolution is California-based Elysian Landscapes’ design for a courtyard beside an Isabel Marant store in Los Angeles, California. Using native plants adapted to the dry southwest climate, the firm formed “casual massings,” out of “loose tufts of perennials” that are bright and exotic, but subtly pay homage to a more traditional planting system. Such examples, found throughout The Authentic Garden, provide inspiration to designers in all climates.”

Urban areas reduce native wildlife biodiversity

Studies have shown that some wildlife species just do not adapt to urbanized areas. Marchetti (2006) and Ritzi (2004) found that there are more native fish species the farther away from urban areas, and Ordenana (2010) showed that many carnivore species decline nearer to cities. A study just published in Urban Naturalist (No. 8, 2015) supports these observations and concluded that while a few bat species can survive in urban zones, there are many more that just don’t go there. In their paper entitled Bat Species Diversity at an Urban-Rural Interface: Dominance by One Species in an Urban Area, Damm, Sparks and Whitaker (2015) determine that while Northern Long-eared Bats were caught in mist nets in urban Indianopolis, Indiana; that others include Tri-colored Bats and Little Brown Bats were negatively correlated the closer they sampled next to the urban core. They conclude that bat-species richness may be connected to specific roosting and foraging requirements, and the possible negative influence of abundant roadways.
