Abstract:
... Since 1963 when chestnut blight was recorded for the first time in Greece, the disease has spread into all 29 chestnut growing prefectures. As a result the national, annual chestnut production was reduced from 18,000 tons in the 1960s to 11,000 tons in 2005. A project for the application of biological control on a nationwide scale was funded and implemented during the period 2007-2009. Hypovirulen ...

Abstract:
... Limited information is available about the impact of grazing on soil and plant nutrient contents in Mediterranean deciduous oak forests grazed by both livestock and wild life. Thus, the main objective of this study was to investigate the effect of wild boar and small ruminants grazing in a coppice oak forest in N Greece. Eight even‐aged stands of similar canopy cover and site quality were selected ...
