The health of tree specimens has deteriorated during the past year by 6.4 percent compared to 2004, according to the 2005 “Inventory of Forest Damage”, published by the Ministry of the Environment. Thus, while 78.7 percent of the trees have a healthy appearance, 19.4 percent have defoliation greater than 25 percent.

The inventory shows a greater deterioration in hardwoods than in the group of coniferous species. The percentage of healthy hardwoods has decreased by 7.2 percent compared to 2004 and the number of dead specimens has increased by 0.4 percent.

With regard to conifers, despite having registered a less pronounced deterioration, they have also been damaged, since the percentage of this group of species (such as pines, firs, cypresses, cedars, junipers, larches, etc.) damaged has increased by 6.1 percent compared to 2004. In addition, according to the study, the records for this group of resinous plants are the worst that have been obtained since the first Forest Damage Inventory was carried out on the European Level 1 Network in 1987.
