Workflow to improve the forest management of Eucalyptus globulus stands affected by Gonipterus scutellatus in Galicia (Spain) using remote sansing and GIS

Abstract

In Spain there are more than 500.000 ha. of Eucalyptus plantations. There represent 3,5 % of the national forest and the 25 % of the timber harvested. Galicia monocultures of Eucalyptus globulus Labill. plantations cover 177.679 ha. and mixed stands of eucalyptus cover 200.000 ha. more. This high productivity has been powered by the absence of pests and pathogens. However, since 1991 the health and productivity of these stands has been threatened by the Eucalyptus snout beetle, which causes a severe defoliation to eucalyptus stands in Galicia.
