Benefits of External Living Walls for Improving Biodiversity

Living walls, also known as green walls, are vertical structures that are covered with plants. They are becoming increasingly popular in urban areas due to their numerous benefits, including improving biodiversity. The stripping away of natural plant species through urbanisation has led to a decline in native plant species. External living walls allow native plant species to flourish, which in turn attracts native insects and birds. This helps to improve biodiversity in urban areas.

  1. Provides Habitat for Wildlife

External living walls provide habitat for wildlife, including birds, insects, and small mammals. These habitats are essential for the survival of these species, especially in urban areas where natural habitats are limited.

  1. Increases Green Space

External living walls increase green space in urban areas. This helps to reduce the urban heat island effect, which is the phenomenon where urban areas are significantly warmer than surrounding rural areas. This effect is caused by the large amount of concrete and other heat-absorbing materials in urban areas. External living walls help to reduce this effect by providing shade and cooling the surrounding area.

  1. Improves Air Quality

External living walls help to improve air quality by absorbing carbon dioxide and other pollutants from the air. This helps to reduce the amount of air pollution in urban areas, which is a major health concern.

  1. Reduces Noise Pollution

External living walls can also help to reduce noise pollution. The plants on the walls absorb sound waves, which helps to reduce the amount of noise that enters the building. This is especially beneficial for buildings that are located near busy roads or other noisy areas.

Example of External Living Walls in Lichfield

We recently installed an external living wall for a client in Lichfield. The living wall was installed on the exterior of a commercial building and was made up of a variety of native plant species. The living wall has provided habitat for a variety of wildlife, including birds and insects. It has also helped to improve air quality in the surrounding area and has reduced noise pollution for the building's occupants.
