NE, SE

5563325-PPT.jpg
Impacts: 

probably has relatively little direct impact on habitats or biodiversity. As an annual species it rarely invades closed vegetation and would not persist as other vegetation develops. It can, however, delay natural successional processes or impede the establishment of native species in disturbed areas.. Altered trophic level
Damaged ecosystem services
Ecosystem change/ habitat alteration
Modification of nutrient regime
Modification of successional patterns
Monoculture formation
Negatively impacts agriculture
Reduced amenity values
Reduced native biodiversity
Soil accretion
Threat to/ loss of native species

Source? likely to be reintroduced: 

S. oleraceus is so widespread globally that few countries are not yet home to it, so its introduction to yet more countries is hardly a serious risk.

Info Blurb: 

Can delay natural successional processes or impede the establishment of native species in disturbed areas.
