The Swedish Red List 2025 – including ecological variables
The Swedish Red List is compiled by the Swedish Species Information Centre (SLU Artdatabanken) at the Swedish University of Agricultural Sciences as part of the environmental monitoring and assessment programme Biodiversity. It includes assessments of the extinction risk of species in Sweden. The Swedish Red List 2025 was published on 24 March 2026 and is the sixth Swedish Red List to use the International Union for Conservation of Nature (IUCN) Red List categories and criteria. During the Red List assessment process, the basis for the assessments varies greatly between different species. Some species groups, such as birds and many mammals and fish, are covered by thorough environmental monitoring with long time series of data. However, for most other species groups, the level of knowledge is considerably more limited, which is taken into account in the Red List assessment methodology. To better understand the assessments, it may be helpful to read Manual och riktlinjer för rödlistning i Sverige 2025 (https://res.slu.se/id/publ/145574). This dataset includes all species that have been categorized as red-listed: Regionally Extinct (RE), Critically Endangered (CR), Endangered (EN), Vulnerable (VU), Near Threatened (NT) and Data Deficient (DD). The dataset consists of three different data files that are available as separate CSV files or as a single Excel file with multiple sheets. The data file/sheet ”Rodlistade_arter_2025” contains all red-listed species and their assigned categories, the criteria leading to the red-list categories and supporting documentation. It also includes information on factors that may negatively affect species’ survival in Sweden, as well as information about the species' regional occurrence, and their association with landscape types, biotopes and substrates. The data file/sheet consists of 5217 rows and 128 columns. The data file/sheet ”Paverkan_taxonrelationer” contains information for the two impact factors where the effects on red-listed species are specified in relation to other taxa. The compiled values for red-listed species that have one or more values associated with different taxon relationships for these factors are presented in the data file/sheet “Rodlistade_arter_2025”. The data file/sheet consists of 556 rows and 13 columns. The data file/sheet ”Substrat_taxonrelationer” contains information for the nine substrate factors where the values for red-listed species are specified in relation to other taxa. The compiled values for red-listed species that have one or more values associated with different taxon relationships for these factors are presented in the data file/sheet “Rodlistade_arter_2025”. The data file/sheet consists of 7035 rows and 30 columns. This dataset contains only species and does not include other taxon categories. For an overview of all red-listed taxa, including subspecies, apomictic species and other taxon categories, refer to the dataset “Red List work 2025: All red-listed taxa as well as all taxa in the categories Least Concerned (LC), Not Evaluated (NE) and Not Applicable (NA)” at the Swedish National Data Service (https://doi.org/10.5878/ffrv-6x57). An overview of all red-listed taxa and their categories is also available in the dataset ”The Swedish Red List 2025” at the Global Biodiversity Information Facility (GBIF, https://doi.org/10.15468/zbbyqv).

The series of publications produced by the International Union for the Conservation of Nature and Natural Resources (IUCN). They provide an inventory on the threat to rare plants and animal species. Information includes status, geographical distribution, population size, habitat and breeding rate. The books also contain the conservation measures, if any, that have been taken to protect the species. There are five categories of rarity status: endangered species; vulnerable organisms, which are those unlikely to adapt to major environmental effects; rare organisms, which are those at risk because there are few of them in the world, such as plants which only grow on mountain peaks or on islands; out of danger species, which were formerly in the above categories, but have had the threat removed because of conservation actions; and indeterminate species, which are the plants and animals probably at risk, although not enough is known about them to assess their status.
Animals, birds, fish or other living organisms threatened with extinction by natural or human-induced changes in their environment.
The plants threatened with extinction by human or natural changes in the environment.
One of the three degrees of "rarity" drawn up by the International Union for the Conservation of Natural Resources. All plants and animals in these categories need special protection. Endangered species are those species in danger of extinction unless steps are taken to change the cause of threat and decline.
The safeguarding, for public enjoyment, of landscape and of opportunities for outdoor recreation, tourism and similar activities; the concept includes the preservation and enhancement not only of what has been inherited but the provision of new amenities and facilities.
Controlled utilization, protection or development of selected classes of plants or animals for their richness, biodiversity and benefits to humanity.
Planned management (i.e. preservation, maintenance, sustainable use, recovery, enhancement) of a natural resources or of a particular ecosystem to halt, reverse or slow-down the loss of biodiversity from impacts of exploitation, pollution etc. to ensure the future usability of the resource, resilience of communities, and ecosystem integrity.
[Henderson's] biological diversity q.v. As defined by the United Nations Convention on Biological Diversity: “the variability among living organisms from all sources, including, inter alia, terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part. This includes diversity within species, between species and of ecosystems.” The number of different living species is estimated at between 40 and 80 million, most of them still undiscovered and uncharacterized, each species containing yet further genetic diversity.
[Henderson's] n. (1) management of the environment and its natural resources with the aim of protecting it from the damag­ing effects of human activity; (2) the main­tenance of a nucleotide or protein sequence relatively unchanged over evolutionary time and in different species.
Una especie se considera en peligro de extinción, sea vegetal o animal, cuando se encuentra comprometida su existencia globalmente. Esto se puede deber tanto a la depredación directa sobre la especie como a la desaparición de un recurso del cual esta dependa, tanto por la acción del hombre, debido a cambios en el hábitat, producto de hechos fortuitos o por cambios graduales del clima. En la versión 2009 de la Lista Roja de la UICN 2.448 taxones de animales y 2.280 de plantas se encuentran bajo la categoría 'En Peligro', junto con otros 1.665 taxones de animales y 1.575 de plantas que también lo hacen pero bajo la categoría de 'En peligro crítico'. Muchas naciones cuentan con leyes para proteger a las especies que dependen de su conservación para existir, por ejemplo con la prohibición de su caza. Sin embargo, pocas especies obtienen una protección legal considerable, extinguiéndose muchas sin ningún tipo de reconocimiento público. La extinción de una especie es irreparable y, de momento, irreversible, afectando de manera directa o indirecta a la cadena alimentaria y, eventualmente, al propio ser humano. , "Gatunek zagrożony – w znaczeniu ogólnym to gatunek w większym lub mniejszym stopniu zagrożony wyginięciem, w wąskim znaczeniu to jedna z kategorii zagrożenia stosowanych do klasyfikacji gatunków zagrożonych wyginięciem. , "En utrotningshotad art är en art som hotas av utrotning, antingen på grund av att den till antalet är få, eller att den hotas av förändrande miljömässiga eller rovdjursparametrar. Dessa finns ofta med på IUCN:s rödlista, som i Sverige hanteras av ArtDatabanken. IUCN har beräknat att antalet utrotningshotade arter är 40% av alla organismer. Bara en liten andel av det totala antalet beskrivna arter i världen har dock utvärderats av IUCN. Enligt forskare finns det med stor sannolikhet också många hotade arter som människan ännu inte har upptäckt. Många länder äar lagar som erbjuder skydd till arter; de skydden kan vara att förbjuda jakt, fridlysa dem, skapa naturreservat, och så vidare. I Sverige arbetar Naturvårdsverket, ArtDatabanken och länsstyrelserna med Åtgärdsprogram för hotade arter för att försöka bevara dem. Orsaker till att arter blir utrotningshotade är flera, men bland de mest påtagliga är habitatförlust. Även för hård jakt, fiske eller annan typ av fångst eller insamling kan vara orsak till att en art blir utrotningshotad. Den internationella handel med utrotningshotade djur och växter hanteras av CITES. , "Uma espécie ameaçada é uma espécie cujas populações estão decrescendo a ponto de colocá-la em risco de extinção. Muitos países têm legislação que protege estas espécies, proibindo a caça e protegendo seus habitats, mas essa legislação tem se demonstrado insuficiente para evitar que um número crescente de espécies deixe de existir, sem que se tenha notícia deste fato. Não há consenso sobre os critérios de inclusão de uma espécie na lista das ameaçadas. Há uma interpretação corrente de que a preservação de espécies ameaçadas é incompatível com a exploração económica do ambiente em que vivem, que deveria ser preservado como um santuário ecológico intocável. Isto é verdade em alguns casos extremos, mas não em todos. Cresce o número de propostas de uso económico sustentável de habitats naturais, combinando agricultura com preservação da cobertura vegetal e portanto da diversidade da flora e da fauna. No Brasil, a legislação tem feito alguns avanços nos últimos anos, embora na prática a falta de fiscalização e a impunidade dos infratores implique em que não seja respeitada. , "Uhanalaisuus määritellään perinteisesti siten, että eliölajiin tai sen populaatioon kohdistuu lopullisen häviämisen vaara. Lajin uhanalaisuuden arviointi on lajin levinneisyyden, yleisyyden ja runsauden muutosten ennakoimista käytössä olevien tietojen perusteella. Uhanalaisuutta arvioitaessa populaatioiden häviämisnopeus on olennainen tekijä, ja uhanalaisten lajien suojelutyössä häviämisnopeuteen pyritään vaikuttamaan eri keinoin. , "Si definisce specie a rischio una specie animale o vegetale che, a causa della esiguità della popolazione ed in virtù di sopravvenuti mutamenti nel suo habitat usuale, è a rischio di estinzione. , "瀕危物種(Endangered species)是指由於濫捕、盜獵、環境破壞、數量稀少、棲地狹窄等種種原因導致有滅絕危機的物種。 一個關鍵物種的滅絕可能破壞當地的食物鏈，造成生態系的不穩定，並可能最終導致整個生態系統的崩解。 , "En biologie et écologie, le terme espèce menacée s'applique à toute espèce qui risque de disparaître. , "An endangered species is a population of organisms which is at risk of becoming extinct because it is either few in numbers, or threatened by changing environmental or predation parameters. The International Union for Conservation of Nature (IUCN) has calculated the percentage of endangered species as 40 percent of all organisms based on the sample of species that have been evaluated through 2006. Many nations have laws offering protection to conservation reliant species: for example, forbidding hunting, restricting land development or creating preserves. Only a few of the many species at risk of extinction actually make it to the lists and obtain legal protection like Pandas. Many more species become extinct, or potentially will become extinct, without gaining public notice. , "En truet dyreart er en art som av ulike grunner står i fare for å bli utryddet. Mange land har lover som gir spesiell beskyttelse til disse dyreartene (lover som for eksempel kan forby handel og jakt, eller forby utvikling av dyreartenes naturlige habitat og lignende), for å unngå at de blir totalt utryddet. Bare noen få av de mange truede dyreartene kommer på listen og blir gitt beskyttelse ved loven. Mange flere dyrearter blir utryddet, eller vil potensielt bli utryddet, uten å få offentlig oppmerksomhet. At en dyreart havner på en liste over truede dyrearter kan også være en ulempe, siden det gjør dyrearten mer verdifull og ønsket blant samlere og krypskyttere. , "Trua arter er arter som trues av utryddelse (står i fare for å dø ut). Trusselbildet kan variere, både mellom artene og innad i en art, herunder også både internasjonalt og nasjonalt. Verdens naturvernunion (IUCN) har derfor utarbeidet ei internasjonal rødliste for bedre å kunne ivareta internasjonale og nasjonale spørsmål om trua arter. Den internasjonale rødlista ivaretas av Species Survival Commission (SSC), mens nasjonale rødlister ivaretas av et lokalt oppnevnt organ. , "Tiedosto:Status iucn3.1 EN fi. svg Erittäin uhanalainen laji IUCN:n uhanalaisuusluokittelussa. Erittäin uhanalainen laji on eliölaji, jonka vaara kadota luonnosta lähiaikoina on erittäin suuri. Esimerkiksi yksi erittäin uhanalaisista lajeista on gorilla.. Suomessa erittäin uhanalaisia lajeja ovat muun muassa jokihelmisimpukka ja ahma.. Kaiken kaikkiaan vuoden 2000 uhanalaisarvioinnissa luokiteltiin Suomen eliöistä erittäin uhanalaisiksi 5 nisäkäslajia, 6 lintua, 4 kalaa, 242 selkärangatonta, 52 putkilokasvia, 37 itiökasvia ja 106 sienilajia eli yhteensä 452 eliölajia. Kansainvälisen luonnonsuojeluliiton IUCN:n uhanalaisuusluokituksessa erittäin uhanalainen (EN, Endangered) on yksi uhanalaisuuden tasoista.
