The Pest Risk Analysis (PRA) protocol, developed by EPPO, was applied in Riserva San Massimo, SCI IT2080015 (Gropello Cairoli, PV ‐ Italy), that hosts a black alder wood (habitat 91E0*) in which populations of Solidago gigantea Aiton and Amorpha fruticosa L. have been surveyed. Results confirm that S.gigantea and A.fruticosa mostly invade the habitats where native species competition is lower and anthropic disturbance intense. The high naturalness and biodiversity of the habitat 91E0* effectively counteracts IAS spread within itself, where vegetation is thicker and anthropic disturbance low. IAS population density is medium limited in wood clearings and at its edges. However, Riserva San Massimo plant biodiversity is seriously threaten by S.gigantea. PRA application in a limited area represents a valid tool to determine the level of risk of invasion associated with alien species and to update the Reserve Management Plan actions against them.

Abstract
The Pest Risk Analysis (PRA) protocol, developed by EPPO, was applied in Riserva San Massimo, SCI IT2080015 (Gropello Cairoli, PV ‐ Italy), that hosts a black alder wood (habitat 91E0*) in which populations of Solidago gigantea Aiton and Amorpha fruticosa L. have been surveyed. Results confirm that S.gigantea and A.fruticosa mostly invade the habitats where native species competition is lower and anthropic disturbance intense. The high naturalness and biodiversity of the habitat 91E0* effectively counteracts IAS spread within itself, where vegetation is thicker and anthropic disturbance low. IAS population density is medium limited in wood clearings and at its edges. However, Riserva San Massimo plant biodiversity is seriously threaten by S.gigantea. PRA application in a limited area represents a valid tool to determine the level of risk of invasion associated with alien species and to update the Reserve Management Plan actions against them.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
