A database of 400 tree species was compiled by German researchers to encourage people and communities in urban areas to plant the right trees in the right places. The data collected by the scientists will help in shifting the focus away from the way trees look towards biodiversity. When cities and urban areas plant trees, their focus is usually on aesthetics but it is important to plant the right trees for the right places.
City planners usually consider 10 to 15 tree species that are planted again and again. According to Juliane Vogt of the Institute of Forest Growth and Forest Computer Science at Techische Universitat Dresden, Germany, there is no biodiversity in the way the trees are selected. The database will provide a huge range of tree species and varieties so that city planners and landscape architects will have a guide on the trees that are suitable for certain places.
There are numerous benefits that can be derived from trees:
• Trees provide shade and reduce urban heat island effect that makes towns and cities several degrees warmer than rural areas.
• Trees provide habitat for animals that made the cities their home.
• Trees interact with humans and the surrounding cities. For some tree species, urban life has presented them with an opportunity for a new beginning.
However, some residents dislike trees particularly when they become the home of raccoons, rats and pigeons that are widely regarded as pests. The once prized Japanese knotweed is an unwelcomed opportunist. When the fruits of pear trees fall to ground, they create a mess on the pavement below. Some people want the pear trees removed even if they are healthy. Through the database, city planners will be able to select suitable trees that will be accepted in urban communities.
In certain situations, tree loppers in Perth is very important because the services are provided by professional arborists. Tree lopping is not dangerous as long as it follows the guidelines provided by the Australian Code of Practice. The process can be conducted safely without any damages to surrounding properties and without compromising the aesthetics of the tree.
