Home›Ferns and Fern Allies›Conservation Status›Least ConcernBrowse ByLeast ConcernConservation status groups species by how close each one is to extinction, using the category scale most conservation scientists rely on, running from least concern through near threatened, vulnerable, endangered and critically endangered, to extinct in the wild or extinct. Assessments come from bodies such as the IUCN Red List and are re-checked as a species population changes. A species with no current assessment recorded here is not shown as any of these categories.FactsLeast ConcernSourcesComments (0)Reader Challenges (0)FactsComparisonReproductive ModeWell-attestedSpores 1Least ConcernFilter Results33 entriesCommon GroupAllHorsetails (Equisetum) (11)True Ferns (Polypodiopsida) (20)Water Ferns (Aquatic Ferns) (1)Whisk Ferns (Psilotum) (1)Everyday GroupAllHorsetails (Equisetum) (11)True Ferns (Polypodiopsida) (20)Water Ferns (Aquatic Ferns) (1)Whisk Ferns (Psilotum) (1)HabitatAllBog (7)Cloud Forest (1)Fen (3)Freshwater Marsh (2)Freshwater Swamp Forest (1)Grassland (4)Lake (2)Riparian Zone (2)River (4)Savanna (2)Temperate Forest (4)Tropical Rainforest (1)Tundra (1)Wetlands (6)Where It LivesAllAfghanistan (8)Africa (6)Albania (18)Algeria (12)Angola (6)Australia (12)Austria (20)Bahamas (6)Bangladesh (8)Belarus (13)Belgium (23)Belize (4)Benin (2)Bolivia (7)Botswana (4)Brazil (7)Bulgaria (19)Burundi (3)Cambodia (5)Cameroon (2)Canada (4)Chad (3)Colombia (6)Comoros (3)Costa Rica (4)Cuba (9)Cyprus (10)Denmark (16)Djibouti (4)Dominican Republic (3)Ecuador (4)Egypt (4)El Salvador (3)Eswatini (6)Ethiopia (6)Fiji (7)Finland (12)France (23)Gabon (3)Georgia (10)Germany (21)Greece (18)Guatemala (5)Guinea (3)Haiti (6)Honduras (6)Hungary (16)Iceland (8)India (10)Iran (16)Iraq (9)Ireland (19)Italy (19)Jamaica (8)Japan (17)Kazakhstan (15)Kenya (7)Laos (6)Lesotho (5)Liberia (3)Libya (7)Luxembourg (7)Madagascar (6)Malawi (5)Mali (4)Manchuria (12)Mauritania (3)Mauritius (6)Mongolia (12)Morocco (12)Mozambique (5)Myanmar (7)Nepal (5)Netherlands (18)Nicaragua (3)North America (27)Norway (16)Pakistan (6)Palestine (9)Philippines (3)Poland (14)Portugal (16)Romania (13)South Africa (4)South America (4)South Asia (12)Spain (15)Sri Lanka (3)Sweden (15)Switzerland (14)Taiwan (4)Tanzania (4)Thailand (3)Tunisia (7)Ukraine (8)United States (5)Uzbekistan (4)Venezuela (3)Vietnam (3)Zimbabwe (3)Showing the 100 most common of 154 options.DietAllPhotosynthetic Autotroph (33)System (Realm)AllFreshwater (12)Terrestrial (29)Terrestrial and Freshwater (1)Living or ExtinctAllYes (33)Relationship to PeopleAllEaten or Drunk by People (3)Farmed or Commercially Raised (1)Invasive or Introduced Species (8)Used in Traditional Medicine (18)CITES AppendixAllNot Listed (32)NatureServe RankAllG4 Apparently Secure (3)G5 Secure (20)GNR Unranked (2)EcosystemAllEverglades (1)Moorland (1)TaxonomyAllAsplenium (3)Polypodiopsida (2)Pteridophyta (16)Show ResultsBrowseCompareSelect all 33Adiantum Capillus-VenerisLeast ConcernBoston FernLeast ConcernBrackenLeast ConcernBranched HorsetailLeast ConcernCinnamon FernLeast ConcernDiplazium EsculentumLeast ConcernDwarf HorsetailLeast ConcernEquisetum ArvenseLeast ConcernEquisetum palustreLeast ConcernField HorsetailLeast ConcernGolden PolypodyLeast ConcernGreat HorsetailLeast ConcernHart's Tongue FernLeast ConcernKillarney FernLeast ConcernLake QuillwortLeast ConcernMarsh FernLeast ConcernMarsh HorsetailLeast ConcernOld World Climbing FernLeast ConcernOstrich FernLeast ConcernPteridium AquilinumLeast ConcernRough HorsetailLeast ConcernRoyal FernLeast ConcernRustyback FernLeast ConcernRusty-back FernLeast ConcernScouringrush HorsetailLeast ConcernSensitive FernLeast ConcernSouthern Giant HorsetailLeast ConcernSouthern Maidenhair FernLeast ConcernTunbridge Filmy FernLeast ConcernVirginia Chain FernLeast ConcernWater HorsetailLeast ConcernWater SpriteLeast ConcernWhisk FernLeast ConcernSources1.
