The Sustainable Sites Initiative led by the partners developed the rating system out of four years of work by dozens of the country’s leading sustainability experts, scientists and design professionals, as well as public input from hundreds of individuals and dozens of organizations, to create this missing link in green design. The announcement took place at the U.S. Botanic Garden in Washington.
“While carbon-neutral performance remains the holy grail for green buildings, sustainable landscapes move beyond a do-no-harm approach,” said Nancy Somerville, executive vice president and CEO of ASLA. “Landscapes sequester carbon, clean the air and water, increase energy efficiency, restore habitats and ultimately give back through significant economic, social and environmental benefits never fully measured until now.”
“We are facing unprecedented environmental challenges such as water scarcity and climate change that require fundamental changes in the way that we interact with the land," said Susan Rieff, executive director of the Lady Bird Johnson Wildflower Center. “This voluntary rating system and guidelines cover all aspects of working with outdoor spaces of all sizes, and provide information for designing landscapes that go beyond beauty to actually improving ecosystem health and the health of communities for generations to come."
“Landscapes can give back,” said Holly H. Shimizu, executive director of the United States Botanic Garden. “We believe that as these guidelines become widely used, not only will they be as transformative to the landscape industry as LEED was to buildings, but more than that, they will allow built landscapes to be regenerative like natural landscapes, and assist in mitigating some of the most pressing environmental issues we face today. We need to acknowledge our landscapes’ value, treasure them and cultivate them sustainably and responsibly. The need is urgent, the time is now and these guidelines, when used correctly, are the tools.”
The rating system works on a 250-point scale, with levels of achievement for obtaining 40, 50, 60 or 80 percent of available points, recognized with one through four stars, respectively. If prerequisites are met, points are awarded through the 51 credits covering areas such as the use of greenfields, brownfields or greyfields; materials; soils and vegetation; construction and maintenance. These credits can apply to projects ranging from corporate campuses, transportation corridors, public parks and single-family residences. The rating system is part of two new reports issued from the Initiative, “The Case for Sustainable Landscapes and Guidelines” and “Performance Benchmarks 2009,” both available for download at www.sustainablesites.org.
To test the rating system, the Sustainable Sites Initiative opened a call for pilot projects in conjunction with the release of the rating system. Any type of designed landscape is eligible, so long as the project size is at least 2,000 square feet. The call will remain open until Feb. 15, 2010, and the initiative will work with and oversee the projects during the two-year process. More information about the pilot projects is available at www.sustainablesites.org/pilot.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
