Environment sustainability and your backyard

Just because we're in a drought doesn't mean we can't contemplate beautiful running water in our gardens while being aware of environment sustainability.

In these days of water restrictions and looming drought we often forget that water features in our gardens are still very much an option. It's just that they must be sustainable through periods when there is less water, without needing to draw on precious and dwindling reserves in our reservoirs.

Sustainable landscaping - a view to the future

Sustainable landscaping is a matter close to the heart of Phil Johnson of Greenmark Landscapes, recent winner of Landscaping Industries Association Victorian Landscape of the Year and recipient of Waterwise and Water Conservation awards. Johnson specialises in creating landscapes that feature running water drawn from collected and channelled rainwater.

"During dry years the water level drops just like it does in nature," says Johnson, "and then when the rains come it replenishes the whole system. You can save runoff from driveways, roofs and other surfaces, which is then collected in special catchment areas. Pumps then run waterfalls, springs and so on, and you can create that beautiful effect that you get from running water."

What designs can be used to contribute to environment sustainability?

Greenmark specialises in billabongs and other native wetlands, featuring indigenous plants (native to that specific area) that are used to local conditions. Johnson is strict about not planting exotic species in water features, due to their potential to drift in overflows into local water systems and become environmental weeds. He also points to the beneficial effects such natural mini-ecosystems have on the local environment.

"Indigenous water plants provide a fantastic habitat for frogs and rare birds," he says. "And the effect the vibe of the garden has on humans is profound too. You get re-energised just sitting amongst the plants and listening to the sound of running water."

With planning and intelligent design, collected rainwater can also be channelled towards needy, thirsty plants. Areas of the garden can be zoned according to different water needs, with some areas with indigenous plants perhaps not needing to be irrigated, and other spots with planted exotics (or a lawn) being catered for with more water. This philosophy can be translated to smaller, even courtyard-sized yards.
