• Among the worst invasive species that are present at Hidden Springs wetlands are purple loosestrife ( Lythrum salicaria ), mis-named Canada thistle ( Cirsium arvense ), and reed canarygrass ( Phalaris arundinacea ). (boisefrontnature.com)
  • Large patches of purple-flowered Canada thistle ( Cirsium arvense ) grow at the edge of the marsh, interspersed with tall stalks of poison-hemlock ( Conium maculatum ) covered with small white flowers. (boisefrontnature.com)
  • Under high fire frequency, the shrubs and understory species are kept in check. (namethatplant.net)
  • The herbs of frequently burned pine flatwoods include grasses, heaths, legumes, and composites but few of the showy species of the savannas. (namethatplant.net)
  • The species is native to the south-eastern United States, the coastal plain in Virginia, Georgia, and the Carolinas. (wikipedia.org)
  • Because of this, the distinction between "native" and "non-native" becomes increasingly problematic for many species, if not outright arbitrary in some cases (does the plant care if it arrived via waterfowl or human agency? (boisefrontnature.com)
  • The species grows in sandy soils on sand hills or in pine barrens. (wikipedia.org)
  • Slight depressions that have a high clay hardpan occur within the pine flatwoods and harbor the typical species that characterize the savannas. (namethatplant.net)
  • The standard species list is by binary botanical species name. (virboga.de)
  • The Idaho Fish and Wildlife Information System tracks species that are identified as having special conservation status in the following lists. (idaho.gov)
  • Most species lists are not corroborated with herbarium specimens. (nzpcn.org.nz)
  • Note, species lists are not typically an exhaustive presence/absence survey of an area and often may focus on a single habitat or only contain species visible at a particular time of year (for example, spring annual herbs may go unobserved during much of the year). (nzpcn.org.nz)
