Promising new alternatives to tropical hardwoods come with caveats.
The past decade has brought an explosion in the use of tropical hardwood decking and furnishings in public, institutional, and commercial landscapes. Whereas wood decking was once largely the purview of residential landscapes, now it can be found in urban settings from the High Line to West 8’s sculptural Wavedecks. Tropical hardwoods are so durable, hard, and decay-resistant that they appear to be the ideal material, yet the impacts of using even hardwoods certified by the Forest Stewardship Council can be substantial and threaten the most critical ecosystems of our planet.
Wood is a renewable construction material if you compare the amount of time a wood member is in use to the amount of time it takes to grow a tree to yield a comparable piece. But that is not always the case. For example, it takes 90 years to grow a Handroanthus heptaphyllus tree to yield ipe lumber for deck boards, but the deck boards will likely not be in use for 90 years even if they are reclaimed, refinished, and reused.
As concern for the health of tropical forests is increasingly recognized in sustainable design thinking, alternatives to tropical hardwoods (more…)

April is, of course, World Landscape Architecture Month. This year, to mark the occasion, LAM is issuing a special supplement for young readers, called YOUR LAND. It offers a basic introduction to landscape and landscape architecture, a look at the methods and goals of the profession, a breakout of several intriguing types of projects, a career primer, and, not least, a glossary of landscape architecture terms! Our goal is plain: to encourage the making of more future landscape architects. For many people, landscape architecture is a second career choice after they have made their first, and one they like better—it’s mainly a matter of exposure to the wide range of things landscape architects do in their work. We figure sooner is better, so this supplement is free and available digitally for downloading. For limited quantities of bulk print copies for classrooms or other groups, e-mail firstname.lastname@example.org (shipping charges apply).
Our regular April issue is every bit as exciting, covering a range of bold work that is reshaping landscape architecture today. In the cover feature, Michael Dumiak reports on an audacious plan by H+N+S Landscape Architects in the Netherlands, led by Dirk Sijmons, to power the countries around the North Sea with wind energy by the year 2050. It’s a multinational endeavor that transcends bureaucracies as well as boundaries in hopes of making these countries fulfill the goals of the Paris Agreement on climate change, which took effect last year, of holding the average global temperature to within 1.5 degrees Celsius of preindustrial levels by reducing emissions of carbon and other greenhouse gases.
Back in North America, Jack Dangermond and his company, Esri, have done as much or more than anyone since the onset of the digital age to help decode the Earth’s landscape with the computational tools known as geographic information systems, or GIS. At this stage of his career, as Jonathan Lerner profiles, Dangermond is putting that might behind his Green Infrastructure Initiative, the goal of which is “to identify and secure the critical remaining large cores of relatively unspoiled landscape” on a national scale. It is a galactic attempt to counter (more…)
