Some species have no pictures at all, and the gallery only has pictures that might be of help while browsing thumbnails for an unidentified plant. On individual species pages (accessed from the list of species below) there are additional pictures.
List of species
The species in the table below are generally listed as invasive by one or more authorities. All are alien in Alberta, unless noted otherwise (some native species are included to differentiate them from similar exotics). Many additional species are regarded as weeds --- alien species known to occur in Alberta (but not known to be invasive), or native species regarded as pests in agricultural settings. Native species can be invasive (e.g. Aspen incursion into grassland) when not limited by historic disturbance regimes, but are not listed here.
