->Other: There are only few pressures or threats to this habitat type in the largely uninhabited alpine region. Pollution spreading from Russia has some minor effects on water quality. The migration of some salmonid fishes to some rivers in this region from the Baltic sea is blocked downriver. Climate change may result in harmful changes in water temperatures and hydrology, possibly critical for the breeding of some fish species and other animals.

Climate change also increases the risk of nutrient leaching and may cause eutrofication. According to modellings the distribution of aquatic macrophyte and benthic macroinvertebrates may shift northwards. Arctic area is vulnerable to climate change and the changes may be faster than predicted due to recent unfavourable trend of emissions. However, these changes are still very poorly known.

Alpiinisella alueella tähän luontotyyppiin kohdistuu vain vähän uhkia tai paineita. Venäjältä tulevalla kaukokulkeutumisella on joitain vähäisiä vaikutuksia veden laatuun. Joidenkin lohikalojen nousu Itämerestä alueen vesistöihin on estynyt. Ilmastonmuutos saattaa muuttaa vesien lämpötilaa ja hydrologiaa, millä voi olla suuri merkitys joidenkin kalojen ja muiden vesieliöiden kannalta.

Ilmastonmuutos lisää myös ravinteiden huuhtoutumisen riskiä ja voi aiheuttaa rehevöitymistä. Mallinnustutkimusten perusteella mm. vesikasvi- ja pohjaeläinlajien levinneisyysrajojen on arvioitu muuttuvan pohjoisemmiksi. Arktinen alue on herkkä ilmastomuutokselle, ja muutokset voivat olla ennakoitua selvästi nopeampia päästöjen viimeaikaisen epäsuotuisan kehityksen vuoksi. Nämä muutokset ovat kuitenkin vielä heikosti tunnettuja.

->Range: FRV is set as actual value based on distribution, as calculated with the range tool. ||
->Coverage: N/A ||
->HabCondition: Based on the assessments from quality parameters of ecological status for the assessment of the Waterframework Directive, monitoring inside Natura 2000 and other relevant environmental monitoring, it is possible to estimate the condition for 1/3 of the habitat, 2/3 are considered as unkwnown (or uncertain). Thus, the structures and functions for the 1/3 of the actual habitat type is expected to be favourable in >30 % of the cases and the rest is not. For 2/3 of the total area, the situation is considered unknown (uncertain). ||
->Future: N/A ||
->Conclusion: In general for all river types in the region, the ecological status is considered to be good or high in about 50% of the investigated waters in the work according to the framework directive (VISS) and S&F. Hydromorphological parameters coupled to structures and functions was also considered in the expert judgement (information available but not presented here). A major part of the watercourses have less than good status concerning water levels, natural flood regimes. Many rivers are directly affected by water regulation (e.g. hydropower) and dams resulting in unnatural variations in water levels and act as faunal barriers preventing dispersal of organisms. Water systems high up in the system often become oligotrophic. Conclusively, the pressure is ongoing and leads to further deterioration and prevent dispersal of organisms to their natural habitats. About 21 % of the river length (habitat 3210) in boreal region was considered as modified (SMHI 2007) and not considered as habitat type. Conclusively, the pressure is ongoing and leads to further deterioration of important structures and functions and prevent dispersal of organisms to their natural habitats. There is no indication of improvement of the situation on a biogeographical level. Thus, the trend is assessed as deteriorating, as reported 2013. ||

->Other: Range, surface area, structure and function are estimated based mainly on the reports prepared for the WFD. The estimation of surface area is not accurate and informative for the habitat type.

Changes in hydrology and migration barriers, mainly due to building of hydroelectric power plants, have drastically changed most of the major rivers that would belong to this habitat type. There are only few new plans of such structures or practices. However, restorability and capacity to recover are assessed to be poor. Diffuse pollution from agricultural or forestry practices is an important factor negatively affecting the structure and function of the habitat type. Activities related to forestry such as clear felling, soil preparation and fertilization, as well as agriculture and extraction of peat cause an indirect change in the flow rate and result in increased nutrient, solids and humic loads that degrade the water quality.

One fourth of the length of these rivers have been estimated, with reference to WFD, to be in less than good ecological condition.

Luontotyypin levinneisyyden, pinta-alan sekä rakenteen ja toiminnan arvioinnissa on käytetty hyväksi VPD:n toimeenpanoon liittyviä selvityksiä. Pinta-ala ei ole tämän luontotyypin kohdalla erityisen tarkka ja informatiivinen muuttuja.

Lähinnä vesivoiman rakentamisesta johtuvat muutokset hydrologiassa ja vaellusesteet ovat muuttaneet monia jokireittejä, jotka olisivat muutoin kuuluneet tähän luontotyyppiin. Lisärakentamista ei juuri suunnitella, mutta jo muutettujen jokireittien palautuminen tai ennallistaminen ei ole todennäköistä. Maa- ja metsätalouden aiheuttama hajakuormitus on tärkeimpiä syitä, miksi luontotyypin toiminta ja rakenne ovat heikentyneet. Esimerkiksi metsien avohakkuut, maanmuokkaus ja lannoitus sekä maatalous ja turvetuotanto muuttavat välillisesti virtaamia ja aiheuttavat liettävää ja rehevöittävää ravinne-, kiintoaines- ja humuskuormitusta.

Noin 20 % luontotyyppiin kuuluvien jokien pituudesta on arvioitu tilaltaan VPD:n mukaisessa luokittelussa hyvää huonommaksi.

->Conclusion: In general for all river types in the region, the ecological status is considered to be good or high in about 30% of the investigated waters in the work according the framework directive and S&F. Hydromorphological parameters coupled to structures and functions was also considered in the expert judgement (information available but not presented here). A major part of the watercourses have less than good status concerning water levels, natural flood regimes and other hydrological functioning. The presence of important structures as large woody debris is insufficient. Many rivers are directly affected by water regulation (e.g. hydropower) and dams resulting in unnatural variations in water levels and act as faunal barriers preventing dispersal of organisms. Water systems high up in the system often become oligotrophic. Conclusively, the pressure is ongoing and leads to further deterioration and prevent dispersal of organisms to their natural habitats. About 43 % of the river length (habitat 3210) in boreal region was considered as modified (SMHI 2007) and not considered as habitat type. Thus, the pressure is ongoing and leads to further deterioration of important structures and functions and prevent dispersal of organisms to their natural habitats. Historically, to be able to transport timber, a lot of the water courses have been straightened and canalized. Restoration is done however many objects need to be restored so the rate is slow. There are still effects of acidification and even if the acidified precipitation is decreasing, recovery are slow in some regions, especially south-west Sweden. Management of water levels cause erosion and may hinder establishment of plants in the littoral zone. Many rivers lack functional littoral zones. Alien species spread naturally or are facilitated by compensation releases. Water quality is negatively affected by acidification and pollutants (nutrients, metals, chemicals). There is no indication of improvement of the situation on a biogeographical level. Thus, the trend is assessed as deteriorating, as reported 2013. ||
