Plants are central to a functioning global ecosystem. Plants oxygenate the atmosphere and reduce atmospheric pollutants. Reforestation in both developed and developing countries is a primary strategy for mitigating the effects of man-made greenhouse gas (GHG) emissions. However, plants are not only key to the global ecosystem, but also crucial to human health.
Through "integrated site design," a comprehensive approach to sustainable building and site design, sustainable residential landscape architecture practices can not only improve water and energy efficiency, but also use plants to eliminate chemical fertilizers, produce food, restore ecosystems, and clean air. If part of a broader integrated site design, sustainable residential landscape architecture can extend the many benefits of plants.
Integrated site design is a framework for increasing the quality of the built environment, and involves maximizing existing natural systems to create productive and healthy residential environments. These types of designs leverage the many benefits of natural systems, thereby significantly cutting down the use of chemical fertilizers and pesticides. Decreased chemical fertilizer use means homes are healthier, and ecosystems more resilient.
Homeowners can use plants to recreate healthy ecosystems in residential areas, and reduce some of the adverse effects of residential buildings on ecosystems. There are a number of ways to extend the benefits of plants: restoring native plants to residential landscapes, using plants as food sources within residences, creating wildlife habitat through the strategic use of certain plants, adding indoor plants to improve air quality and human productivity, and creating residential composting systems for efficient waste removal.
Local governments are also partnering with non-profit organizations to increase public awareness about using sustainable residential design practices to create productive plant systems.

Native plants are crucial to restoring local ecosytems found in residential areas. These types of plants are great habitat for wildlife, and increase local biodiversity. Due to their hardiness and high resistance, native plants can effectively filter stormwater and greywater. Native plants are low maintenance and, when established, require minimal irrigation.
In addition to their inherent environmental benefits, native plants reduce the need to use pesticides, which runoff into water supplies, and equipment that release a range of pollutants and can cumulatively affect air quality.
Native plant benefits include:
- Reduced environmental contamination: Native plants reduce the need to use chemical fertilizers, pesticides and other toxic lawn maintenance treatments.
- Increased water quality: Native plants filter stormwater and greywater
- Improved air quality: Landscape maintenance equipment produces up to five percent of ozone-forming volatile organic chemicals (VOCs) and can also emit toxic particulates. Due to the inherent low maintenance nature of native plants, the need for mowing and other conventional maintenance equipment can be eliminated.
There are a variety of native plants and selection depends on local soil type and site conditions. Many localities around the world fund registries of local native plants.

Indoor and outdoor residential agriculture is not only visually appealing, but also productive -- edible gardens can produce food at low-cost all year. Edible gardens feature the use of trellis, pots and cages for growing fruits, vegetables, herbs.
Local governments are working with communities to expand the growth of urban and residential farming schemes, community vegetable gardens, and home-based garden plots. Many municipal and local governments offer grants and other forms of support to community groups starting productive gardens in residential areas.
In her effort to fight obesity and encourage healthier eating, U.S. First Lady Michelle Obama recently planted a White House vegetable garden to highlight the benefits of organic home-grown produce. Alice Waters, award-winning chef and owner of Chez Panisse, is also promoting the use of community and school-affiliated edible educational gardens. Her goal is increase inner-city children's exposure to healthy foods, and incorporate fresh produce into U.S. school lunch menus.

Residential Wildlife Habitat: Supporting bees
Plants play a crucial role in creating wildlife habitat for a range of birds, insects, and herbivores. Bees, in particular, depend on wildlife habitat and, with increasing rates of "colony collapse disorder", are worth focus.
Bees play an important role in keeping natural habitats functioning, and provide vital ecosystem services such as pollination. Bees also provide honey and beeswax, which are used in a range of products. However, bee populations have severely declined and are now exhibiting "colony collapse disorder" in many places due to the growth of pesticides and other chemicals.
There are several simple and cost-effective ways to support bee population growth. Homeowners can invest in urban and residential beekeeping systems, as well as natural habitats that attract bees. Research shows that a number of plants specifically attract bees through their nectar and pollen.

Indoor plant systems range from common house plants to more complex indoor-outdoor vertical wall systems. Indoor plants can dramatically improve indoor air quality and human producitivity and health. Plants improve indoor air quality by filtering air pollutants. Research demonstrates that plants effectively eliminate a range of common indoor air pollutants.
Additionally, humans have a biophilic response to plants. New research is exploring how exposure to plants (or even images of plants) can improve productivity and create a sense of well-being.
Indoor plant benefits include:
- Improved indoor air quality: indoor plants filter common household air pollutants. With the right plants, indoor plants can reduce up to 87 percent of air pollutants.
- Improved health: Up to ten percent reduction of rates of asthma, headaches, and respiratory problems.
- Increased human productivity: Productivity rates can increased by 20 percent in environments with superior air quality.
- Reduced energy usage: Energy usage can be reduced by 15 percent because less air circulation is required with indoor plants.

According to the Sustainable Sites Initiative, in 2007, approximately 33 million tons of yard waste entered the municipal waste stream, representing 13 percent of total municipal waste in the United States.
Integrated site designs can include comprehensive systems for minimizing household and landscape-related waste. Instead of sending decomposed organic material to the landfill, composting can increase landfill life by diverting organic materials to residential decomposition systems. More than 25 percent of waste disposed in landfills are yard and food waste, which can instead be transformed into productive resources.The process of composting is cost-efficient when compared with conventional ways of remediating contaminated soils.
Composting decomposes organic material in yard and food waste as well as manures to produce a valuable nutrient-rich medium that can be used to grow healthy plants. There are many benefits to composting. Composting enriches soils, reduce CO2 emissions (through garbage transportation), and provides an efficient way of managing household food waste. Beacause composted materials provide such a rich medium for growing plants, composing reduces the need for excess water, fertilizers, and other pesticides for gardens.
There are various types of composting systems, which can be added to backyards or even used indoors.
