18 April 2018

Recent accidents caused by the fall of trees in parks and public gardens in different Spanish autonomous communities, He has returned to put the need to revise and maintain the arboreal heritage of the cities of today.

The gardens are living areas which need a permanent care, prune, clarear, pay, spray etc., they are activities that will ensure a good image and health of our green areas.

An accident by heavy rains or winds, is unpredictable, but with good maintenance and choosing the suitable species, You can minimize the risk.

De facto, a study by the University of Valladolid, of which the newspaper ABC has echoed, carrying several years carried out studies of monitoring of urban trees has proven that certain varieties fall and dumps more frequently than others.

An example of this is the case of poplar: the Canadian falls much more easily while the indigenous blacks and the Lombards fall with much greater difficulty.

Something similar happens with Elm. While the native Elm enjoys strong and resilient roots, the Siberian (It is very common in parks and gardens for many years), It has one much lower resistance and greater detachment of branches that can lead to accidents.

Another reason favoring the fall of urban trees is that current pavements are not filtering enough and the roots of the trees often can not breathe, What is known as anoxia.

Moreover, as a result they can not host beneficial fungi or mycorrhizal, It helps in the development and maintenance of integrated structures of the trees, hampering their demolition.

How to reduce the risk of accidents in public woodland, will be one of the star of the 3rd International Conference of landscaping and Arboriculture that will take place in the Agora green of the next edition of Iberflora, in a joint call with Eurobrico will be held from 3 rd to 5 th of October at Feria Valencia.
