Major pressures affect the forest and their ecosystems. The European member states record the following forest health indicators in a harmonised way: tree crown condition, soil condition and foliar nutrient content.
Foliar nutrient condition

Tree crown condition, %
Defoliation is defined as needle/leaf loss in the assessable crown as compared to a reference tree. Defoliation is observed regardless of the cause of foliage loss.
Trees are moderately to severely defoliated when defoliation exceeds 25%.

Soil acidity is an important soil property that influences concentrations of important nutrients and minerals. Low soil acidity may cause unfavorable growing conditions for forests.

Deforestation
Deforestation is defined as the permanent conversion of forest land to agriculture, grassland, wetland and urban areas. Deforestation covers forest areas where the impacts of disturbance, over-utilisation or changing environmental conditions affect the forest to an extent that it cannot sustain a canopy cover larger than 10 percent.

Forest fragmentation
Forest fragmentation is breaking large, contiguous forested areas into smaller forest patches, separated by roads, agriculture, utility corridors or other anthropological developments.
Fragmentation is one of many factors that threaten forest health and vitality. Large and intact forest ecosystems are essential to maintaining a good forest condition and biodiversity. Increased fragmentation means that the forest area in the largest patch sizes will decrease and that the small size classes will increase.

Invasive alien species in forest ecosystems
Invasive species are a threat to the local biodiversity and ecosystem. They often have no natural enemies in the introduced area.
