Systems Affected (standardized):
cropland/pastureland, disturbed/waste areas
Regions(s) present (updated by AB):
PH, SE, SW
Impacts:
Negatively impacts agriculture
Negatively impacts tourism
Reduced amenity values
Reduced native biodiversity
Source? likely to be reintroduced:
The dispersal and spread of A. fatua is closely associated with the cultivation of cereal crops around the world. In a study examining weed dispersal within fields, patches of A. fatua typically advanced by 1-3 m in a single year with some movement of up to 30 m noted (Wheeler et al., 2001). Movement was in the direction of cultivation and harvesting. Movement over longer distances is most likely the result of importation of contaminated grain.
Info Blurb:
Replaces native species, reducing biodiversity. Dispersal and spread is closely associated with the cultivation of cereal crops, most likely the result of importation of contaminated grain.
