When we think of green space in a city, we think of trees, parks and gardens. Seldom do we think of these areas as self-sustaining ecosystems, yet they can and should be. Approaching landscape in this way brings multiple benefits but requires a subtle shift in thinking and a new way of understanding plant communities.
Landscapes are all about creating micro-climate, or would be, if designed for that goal. Why is this important and what do I mean? Almost all life is contained in a thin crust of soil, a wedge of atmospheric gases, and water. Plants are the principal medium that interacts with and regulates all three. Absolutely nothing
NOTE: This article was first written in 2006, so some aspects have been updated to reflect current realities. Biomembranes is a term I’m borrowing from biology (the structure bounding a cell) to describe the outer skin of future self-sustaining buildings. I have stated elsewhere that I believe that for the built environment – and therefore
Almost all urban landscapes are contrived and designed, due to their artificial nature and short timescales of development and use. We see increasing use of mature rootballed trees and extensive hard landscape and this is normal for intense inner urban areas; I do get concerned that the increasing complexity of urban planting systems divorce trees particularly
We are now a decade into the explosion of living or green walls. There have been many successes and some notable failures along the way, some of of which may be system-induced and some caused by inadequate or inappropriate maintenance regimes. Assuming we now have systems that work at least reasonably well, what is required by
There is something incredibly exciting about living walls. Stacking green plants on the vertical plane on buildings, where you’d think they just should not be, goes against the odds. Yet nowadays they are almost commonplace, and most people have encountered one somewhere. They cling to life with extraordinary tenacity, usually in a growing medium only
