Interactions of noise and urban greenery with special reference to biodiversity

Abstract

Today, modern roads are one of the biggest polluters in environment. Noise pollution affects human health manifesting itself in physical, physiological and psychological effects. In urban areas noise adversely affects populations of urban animals, primarily birds. This paper provides an overview of professional and scientific issues related to the interaction of noise and urban greenery with special reference to biodiversity. Greater emphasis is placed in using fruity and ornamental species in public city green areas in order to preserve bird diversity. In order to reduce noise from traffic, various sound barriers are built, and recently, green vertical sound barriers have also been in use. Green vertical sound barriers reduce noise and air pollution. City greenery has a number of positive effects on health and reducing noise. Vertical gardens also give a certain level of sound insulation and accumulation sound. For example, plant covers are known to mitigate higher frequency sounds more effectively. compared to lower. Roof gardens, in addition to thermal insulation, reduce noise intensity. There are also certain specifics that plant species have that has effect of reducing noise. It is important to note that there are a number of ways to plant suitable plants in order to reduce noise, and even if they are autonomus, we also affect the preservation of biodiversity. Choosing suitable plant species is very important for the life of birds in the city. in this paper specific species suitable for birds are listed. it is very important to inform and educate citizens about the issue of implementation biodiversity conservation.
