Benefits

Maintenance

Natural landscaping is adapted to the climate, geography and hydrology and should require no pesticides, fertilizers and watering to maintain, given that native plants have adapted and evolved to local conditions over thousands of years. [1] [2] However, these applications may be necessary for some preventive care of trees and other vegetation.

Native plants suit today's interest in "low-maintenance" gardening and landscaping, with many species vigorous and hardy and able to survive winter cold and summer heat. Once established, they can flourish without irrigation or fertilization, and are resistant to most pests and diseases.

Many municipalities have quickly recognized the benefits of natural landscaping due to municipal budget constraints and reductions and the general public is now benefiting from the implementation of natural landscaping techniques to save water and create more personal time.

Ecology and habitat

Native plants provide suitable habitat for native species of butterflies, birds, pollinators, and other wildlife. [3] They provide more variety in gardens by offering myriad alternatives to the often planted introduced species, cultivars, and invasive species. The indigenous plants have co-evolved with animals, fungi and microbes, to form a complex network of relationships. They are the foundation of their native habitats and ecosystems, or natural communities. [4]

Such gardens often benefit from the plants being evolved and habituated to the local climate, pests and herbivores, and soil conditions, and so may require fewer to no soil amendments, irrigation, pesticides, and herbicides for a beautiful, lower maintenance, and more sustainable landscape.

Habitat challenges

However, while local provenance plants have adapted to local conditions (which includes climate, soil, and other native plants and animals), there will often be instances, especially in cities, where one or more of these will have been radically altered.

Examples include:

  • Building rubble used as landfill may raise soil pH (i.e. create alkaline soil), which can be problematic in regions of acidic soils (with local plants adapted to acid soils).
  • Buildings cast a substantial shade, this may give rise to conditions substantially shadier than needed by local plants.
  • Soil which is high in organic material and nutrients is often introduced into gardens, or many gardeners will have used fertilizers. Plants from some areas may not thrive under these conditions. For example, many Australian plants are particularly sensitive to phosphorus.
  • Many native plants are adapted to, and benefit from, periodic wildfires that occurred before and during pre-modern settlement. These fires can be simulated in the garden by either "high mowing" or a controlled burn every few years.

Many weeds in an area are usually the result of imported plants. These plants become invasive because there are no natural controls such as disease, weather, or fauna in their new environment. They take over native habitats, reducing shelter and food for local fauna. Using local provenance plants increases the biodiversity of and is important for the health of a region's overall ecology.

Much of the wild areas have been destroyed to make room for urban development. Housing developments have replaced native habitats with ornamental plants and lawns, pushing the wildland–urban interface further out. While development won't be stopped, gardeners can keep wild areas and green spaces filled with native species on their lots and in their communities.

Despite this, there are usually plenty of indigenous or native plants which will grow and thrive in the area one is trying to establish a native garden.

Native plants

The use of native plants in a garden or landscape can both preserve and protect natural ecosystems, and reduce the amount of care and energy required to maintain a healthy garden or landscape. Native plants are adapted to the local climate and geology, and often require less maintenance than exotic species. Native plants also support populations of native birds, insects, and other animals that they coevolved with, thus promoting a healthy community of organisms.

Plants in a garden or maintained landscape often form a source population from which plants can colonize new areas. Avoiding the use of invasive species helps to prevent such plants from establishing new populations. Similarly, the use of native species can provide a valuable source to help these plants colonise new areas.

Some non-native species can form an ecological trap in which native species are lured into an environment that appears attractive but is poorly suited to them.

However, in Britain research by the University of Sheffield as part of the BUGS project (Biodiversity in Urban Gardens in Sheffield) [5] has revealed that for many invertebrates the majority of wild animals in most gardens it is not just native plants which can sustain them. The findings were published in popular form in Ken Thompson's book 'No Nettles Required: The truth about wildlife gardening' [6] He confirms the approach which Chris Baines had promoted in 'How to Make a Wildlife Garden'. [7]

Some ecosystems may benefit from any increase in biomass, from the introduction of certain non-native species, or any increase in biodiversity. In the case of disturbed areas some exotic/non-native plants may fare better than the displaced, native inhabitants, in the process increasing the biodiversity and biological biomass. [8]

Types

In general

Native gardens include the following kinds:

Wildflower gardens

"Wildflower" in some nations denominates the numerous showy flowers from some drier climates, most notably southwest Western Australia, southern Africa, and North America.

Some wildflower gardens attempt to recreate a prairie, including native grasses along with flowering plants, i. e. forbs. Such gardens benefit the local wildlife, often attracting birds, butterflies, and small mammals. By carefully choosing the plants for the garden, some of these animals can be encouraged to visit the garden. One popular type of wildflower garden specializes in attracting butterflies and is thus denominated a "butterfly garden".

The native plants cultivated in wildflower gardens often have deep roots, and therefore are effective selections for absorbing surface runoff and allowing the water to infiltrate into the local water table. [9] Wildflower gardens cultivated for capturing runoff in this mode are denominated "rain gardens".

Rain gardens

Rain gardens absorb rainwater from gutters and impervious surfaces and function much better when planted with native plants which tolerate the alternation of flooding and drying.

Advantages

Disadvantages

Effect of new construction

In new construction, builders can either avoid clear cutting or clearing an entire property and disturbing other large flora or builders can completely clear an area of all flora to save construction time and replace the clearing with juvenile specimens once the job is complete. The downside to this is additional costs involved with purchasing replacements. The builder may also choose to plant additional native trees and other flora after construction to help the property blend with natural surroundings.

In some planned developments, natural landscaping is the requirement. Builders may not remove trees larger than a specific diameter and owners may not arbitrarily cut trees without a permit.

Land reclamation

Throughout the world, forested areas are often turned into cattle grazing or farmland. Often this land is then turned into residential or commercial use property. By returning the land back to its original state prior to human disturbance, vast amounts of energy usage and increasing pollution can be reduced. Natural landscaping costs less to install than traditional landscaping and, after the initial few years, reduces maintenance costs, combats erosion, and accommodates storm and flood waters better.

Native plant societies

In many parts of the world there are societies, clubs or local groups, such as Bushcare or ASGAP in Australia, the North American Native Plant Society, Pennsylvania Native Plant Society, [10] or the California Native Plant Society, which are made up of gardeners interested in growing plants local to their area, state or country. In the United States, Wild Ones—Native Plants, Natural Landscapes [11] is a national organization with local chapters in many states. New England Wildflower Society, [12] and Lady Bird Johnson Wildflower Center. [13] provide information on native plants and promote natural landscaping. These organizations can be the best resources for learning about and obtaining local native plants. Many members have spent years or decades cultivating local plants or bushwalking in local areas.

Garden design is the art and process of designing and creating plans for layout and planting of gardens and landscapes. Garden design may be done by the garden owner themselves, or by professionals of varying levels of experience and expertise. Most professional garden designers have some training in horticulture and the principles of design. Some are also landscape architects, a more formal level of training that usually requires an advanced degree and often a state license. Amateur gardeners may also attain a high level of experience from extensive hours working in their own gardens, through casual study, serious study in Master gardener programs, or by joining gardening clubs.

In agriculture and gardening, a beneficial organism is any organism that benefits the growing process, including insects, arachnids, other animals, plants, bacteria, fungi, viruses, and nematodes. Benefits include pest control, pollination, and maintenance of soil health. The opposite of beneficial organisms are pests, which are organisms deemed detrimental to the growing process. There are many different types of beneficial organisms as well as beneficial microorganisms. Also, microorganisms have things like salt and sugar in them. Beneficial organisms include but are not limited to: Birds, Bears, Nematodes, Insects, Arachnids, and fungi. The ways that birds and bears are considered beneficial is mainly because they consume seeds from plant and spread them through feces. Birds also prey on certain insects that eat plants and hinder them from growing these insects are known as non beneficial organisms. Nematodes are considered beneficial because they will help compost and provide nutrients for the soil the plants are growing in. Insects and arachnids help the growing process because they prey on non beneficial organisms that consume plants for food. Fungi help the growing process by using long threads of mycelium that can reach very long distances away from the tree or plant and bring water and nutrients back to the tree or plant roots.

<span class="mw-page-title-main">Rain garden</span> Runoff reducing landscaping method

Rain gardens, also called bioretention facilities, are one of a variety of practices designed to increase rain runoff reabsorption by the soil. They can also be used to treat polluted stormwater runoff. Rain gardens are designed landscape sites that reduce the flow rate, total quantity, and pollutant load of runoff from impervious urban areas like roofs, driveways, walkways, parking lots, and compacted lawn areas. Rain gardens rely on plants and natural or engineered soil medium to retain stormwater and increase the lag time of infiltration, while remediating and filtering pollutants carried by urban runoff. Rain gardens provide a method to reuse and optimize any rain that falls, reducing or avoiding the need for additional irrigation. A benefit of planting rain gardens is the consequential decrease in ambient air and water temperature, a mitigation that is especially effective in urban areas containing an abundance of impervious surfaces that absorb heat in a phenomenon known as the heat-island effect.

The Backyard Wildlife Habitat is a program of the National Wildlife Federation that encourages homeowners in the United States to manage their gardens and yards as a wildlife garden, with the goal of maintaining healthy and diverse animal habitats and ecosystems. The program began in 1973. By 1998, it had impacted more than 21,000 yards and, as of 2006, has certified over 60,000 'backyards'.

<span class="mw-page-title-main">Native species</span> Species indigenous to a given area in geologic time

In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution during history. The term is equivalent to the concept of indigenous or autochthonous species. A wild organism is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species.

Forest farming is the cultivation of high-value specialty crops under a forest canopy that is intentionally modified or maintained to provide shade levels and habitat that favor growth and enhance production levels. Forest farming encompasses a range of cultivated systems from introducing plants into the understory of a timber stand to modifying forest stands to enhance the marketability and sustainable production of existing plants.

Xeriscaping is the process of landscaping, or gardening, that reduces or eliminates the need for irrigation. It is promoted in regions that do not have accessible, plentiful, or reliable supplies of fresh water and has gained acceptance in other regions as access to irrigation water has become limited, though it is not limited to such climates. Xeriscaping may be an alternative to various types of traditional gardening.

Sustainable landscaping is a modern type of gardening or landscaping that takes the environmental issue of sustainability into account. According to Loehrlein in 2009 this includes design, construction and management of residential and commercial gardens and incorporates organic lawn management and organic gardening techniques.

<span class="mw-page-title-main">Climate-friendly gardening</span> Low greenhouse gases gardening

Climate-friendly gardening is a form of gardening that can reduce emissions of greenhouse gases from gardens and encourage the absorption of carbon dioxide by soils and plants in order to aid the reduction of global warming. To be a climate-friendly gardener means considering both what happens in a garden and the materials brought into it as well as the impact they have on land use and climate. It can also include garden features or activities in the garden that help to reduce greenhouse gas emissions through processes not directly related to gardening.
