Lawn and landscape design is changing to meet the challenges of new water requirements and a revived interest in native habitats that encourage native wildlife.

Traditional lawns

Everyone loves a beautiful, freshly cut green lawn, well, almost everyone. More and more people are moving away from the traditional large grass covered areas, opting instead to use more trees, shrubs, and other plants, and they are “going native” with the varieties used in lawn and landscape design.

Water use and phosphorous

I suspect that this trend will continue, as water use restrictions and environmental laws begin to effect the amount of water available for lawn and landscape use, and the allowable nutrient “run off” produced by traditional lawn care. Certain lawn nutrients may eventually be severely restricted, particularly the amount of phosphorous, due to it’s negative effects on lakes, ponds and waterways. Such restrictions are inevitable unless we learn to self regulate. It is only a matter of time.

Traditional lawn grasses

Most of our traditional lawn grasses are not native, and therefore require extra water and nutrients to thrive. While they do produce oxygen and process water fairly efficiently, the extra nutrients, pesticides, and other excesses may make them a less practical practice than in the past.

Traditional landscapes

Traditional landscapes, with their heavy use of exotic plants, are also losing favor. Most of these non native plants require more water, more fertilizer, and more insecticides than their native counterparts.

Lawn and landscape design and biodiversity

There is also a biodiversity issue involved in lawn and landscape design. Who would have ever suspected that so many of the popular landscape plants from the middle of the last century would have taken on the role of environmental terrorists? The Japanese Silk tree, commonly called Mimosa, the Chinaberry, the Chinese Tallow, and a variety of Asian privets are now more prevalent in our woodlands, than in the home lawns where they were once used as landscape plants. Thought to be safe, and non invasive at the time, they have now become a serious threat to native biodiversity throughout the lower half of the country. Which of the currently popular exotics will become problems? It is hard to know, but just because they do not appear to be invasive now, does not mean that they won’t gain a foothold later.

Why non native plants are a problem

When invasive species gain a foothold in our forests and waters, they tend to eliminate the native competition, much of which is needed to support native wildlife. If a native plant preferred by pollinators disappears, the pollinator may move on. This gives the non native an even stronger foothold. It also means that the insects which pollinate food crops may be gone as well.

Non native plants and wildlife

Studies have shown that the nutrient value of most of the non native species is less than that of the native varieties, particularly for native wildlife. As these exotics take over more and more territory, the native wildlife populations sometimes get hungry, and move on. These are just a couple of the hundreds of reasons why biodiversity should be considered when devising a landscape strategy. It is not just an issue in some remote forest or jungle, biodiversity is a problem on the home front as well.

Backyard habitats for lawn and landscape

The fact is, that our traditional ways of dealing with our outdoor habitats are responsible for a number of environmental problems such as water quality, biodiversity, and over use of pesticides. With growing awareness of these effects, many are choosing to take a different approach to lawn and landscape design.

Backyard habitats, or, native habitats, are viable alternatives to traditional lawns and landscape designs. Rather than imposing our will on the environment, we simply allow the native environment to do what it does best, with our assistance. In the long run, there is less fertilizer, water, and pesticide needed. The native varieties are acclimated to the native environments, and native soils, and are resistant to native pests. After the initial installation or modification, there is much less labor involved. It is a cheaper, easier, more environmentally friendly form of landscaping.
