Systems Affected (standardized):
riparian/aquatic, rangeland, forest/woodland, disturbed/waste areas
Regions(s) present (updated by AB):
The teasels form large dense stands that choke out desirable plant species. This can reduce forage, wildlife habitat, and species diversity.
Source? likely to be reintroduced:
The seedheads of D. fullonum are often used in dried flower arrangements and the transfer of seeds still trapped in the seedheads from country to country or within countries could be a source of new introductions. There are many sites online selling seeds and this is another possible high risk pathway for introductions. Introduction in contaminated crop seed is unlikely, because D. fullonum seed ought to be identified in phytosanitary searches.
Forms large dense stands that choke out desirable species, reducing forage, wildlife habitat, and diversity. Seedheads are used in dried flower arrangements, potentially introducing the species to new areas.
