PP-ICON / Plant-Pollinator Integrated CONservation approach: a demonstrative proposal – LIFE09/NAT/IT000212

threats and risks

Threats to future persistence of populations of D. albus are associated mainly to the enlargement of wood and its progressive closure, as a consequence of recent human changes in land-use; moreover, suitable habitats are rare, often separated from each other by significant distances, and usually surrounded by agricultural landscapes. In addition to these risk factors, recent studies showed that seed output is pollen-limited, indicating a deficit in pollinator service.

While not threatened at global level, D. albus is considered rare: it has been designated as “vulnerable” and it is locally protected in many European Countries (Italy, France, Germany, Spain, Czech Republic, Slovakia, Poland).
