Los bosques con mayor diversidad de árboles producen más maderaThe forestrys with greater diversity of trees produce more wood
22 February 2013
The forestrys with greater variety of species of trees produce of average 24% more than wood that those that present an alone type of tree. It is one of the conclusions to which has arrived a study led by the Upper Council of Scientific Investigations (CSIC) in which they have analysed more than 55.000 plots in 11 types of different forestrys in Spain, France, Low Countries, Switzerland and Sweden. The results have been published in the magazine Plos One. The data recopilados in this work show an increase in the satisfied wooden production increases the wealth of arboreal species in almost all the types of forestrys studied. Besides, this relation keeps when also they take into account the climatic differences between plots. It treats of the first empirical analysis that treats to discover the existence of a positive relation between wealth of arboreal species and wooden production for all a continent.

“Many of the European forestrys have a structure of uneven age, have been historically very handled, are young and the basal area by individual has not reached still his maximum. Therefore, a greater number of arboreal species, with roots to distinct depths and multiple layers of foliage, could comport an increase in the efficiency by the use of the resources in of ecosystem”, explains the researcher of the CSIC Montserrat Vilà, of the Biological Station of Doñana.
Another of the likely causes of this phenomenon, adds the study, is that in the richest plots in species is used to to predominate at least an arboreal species very efficient in the use of the resources, that is the manager of the greater part of the productivity of the forestry. Both mechanisms could act simultaneously, as well as alternate along the time, with transitions of several decades of length.
Absorption of carbon
The forestrys have a big capacity to absorb the atmospheric carbon and are considered the greater sumidero terrestrial of this element. The wooden production is one of the main agents of the absorption of carbon. The results of the study suggest that the preservation of the forestrys with high diversity of arboreal species could increase this phenomenon. “The importance of the biodiversidad, although little considered up to now, would have to be incorporated in all type of plan of gestión and of forestry politics”, adds the researcher of the CSIC. This work engloba inside the European project Biodiversidad and climatic change: an analysis of risk (Baccara).
