  • PF: for the habitat types that can have a non-priority as well as a priority form (6210, 7130, 9430) enter "X" in the column PF to indicate the priority form.
  • NP: in case that a habitat type no longer exists in the site enter: x (optional)
  • Cover: decimal values can be entered
  • Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation)

3.2 Species referred to in Article 4 of Directive 2009/147/EC and listed in Annex II of Directive 92/43/EEC and site evaluation for them

  • S: in case that the data on species are sensitive and therefore have to be blocked for any public access enter: yes
  • NP: in case that a species is no longer present in the site enter: x (optional)
  • Type: p = permanent, r = reproducing, c = concentration, w = wintering (for plant and non-migratory species use permanent)
  • Unit: i = individuals, p = pairs or other units according to the Standard list of population units and codes in accordance with Article 12 and 17 reporting (see reference portal)
  • Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

4.2 Quality and importance

Acksjn ligger ca 3,5 km ostsydost om Rdns kyrka, ca 10 km nordvst om stersunds centrum, p Rdhalvns yttersta del nra Storsjns strand. Krret utgr resterna av en torr-lagd sj, Acksjn, som dikades ut p 1600-talet. I objektet ingr blekeflt, topogent krr och sumpskog. Omrdet r flackt och ligger ca 290 - 300 m..h., d.v.s. ngot hgre n Storsjns yta. Berggrunden bestr av Andersskiffer och kalksten. Jordarterna r leriga morner, islvsgrus, bleke och visst inslag av torv. En bck, Vikebcken, passerar genom omrdet. En mindre bck rinner in i omrdets vstra del och ansluter till Vikebcken i vtmarken. Vid fastmarks-kanten i vstligaste delen finns flera klluppkommor med utstrmmande markvatten. Lngs sdra och stra sidan lper en gruss som en sarg runt omrdet. Blekefltet r torrt och vldigt hrt med en gles vegetation med bl.a. krrfrken Equisetum palustre, hsthov Tussilago farfara, jmtstarr Carex lepidocarpa ssp. jemtlandica och hrstarr Carex capillaris. ven guckusko Cypripedium calceolus (NT), flugblomster Ophrys insectifera, tvblad Listera ovata , kattfot Antennaria dioica, vildlin Linum catharticum och jmtlandsmaskros Taraxacum crocodes (VU) frekommer i den extrema kalkmiljn. Bland mossorna kan nmnas skr kalkmossa Tortella fragilis, kruskalkmossa Tortella tortuosa och plyschgrusmossa Ditrichum flexicaule. Skyfallsalg Nostoc commune frekommer i bleke-fltet. Buskskiktet bestr av delvis tta snr med en Juniperus communis. Enlav Vulpicida juniperinus vxer rikligt bde p enbuskarna och i kalkbleken runt dem. Det ppna topogena fastmattekrret hyser en kalkgynnad vegetation med bl.a. blttel Molinia caerulea, hirsstarr Carex panicea, tuvsv Trichophorum cespitosum ssp. cespitosum och kalkindikatorn axag Schoenus ferrugineus. Hr frekommer ven brudsporre Gymnadenia conopsea, tvblad, flugblomster och i stora mngder den rdlistade guckuskon. Brunmossorna i bottenskiktet representeras av guldsprrmossa Campylium stellatum och spd skorpionmossa Scorpidium cossoni. Den vstligaste delen bestr av en relativt ppen rikmyr med kllmarksparti och en mindre bck / rnnil. Hr finns ocks ngra sm ppna vattenytor. Delvis inslag av lvdominerad sumpskog med frmst glasbjrk Betula pubescens, gral Alnus incana och viden Salix sp.. Sumpskogsdelarna har varierande trdslagsdominans. P fastare mark i och runt blekeflten i norra delen dominerar tall Pinus sylvestris, lokalt gran Picea abies med inslag av glasbjrk. Bestndsldern i den delen uppges till ca 120 r. I de centrala och vstra delarna blandsump-skog, delvis lvdominerad. Kantzonerna runt omrdet vxlar frn extremt torra - fuktiga partier. Trdskiktet lngs kanterna r ofta lvdominerat, men lokalt i norra och vstra delarna finns tall- eller grandomi-nerade partier. Trdldern i kantzonerna r frn ca 50 r och uppt. Svl i kantzonerna som ute i sumpskogspartierna finns ett ptagligt inslag av senvuxen gran och tall. Vikebckens utlopp genom grussen, den s.k. Kringgraven, r en ravinartad genombrytning i grussen. Hr har det funnits bde sg och kvarn, men r sedan lnge bevuxen med en rtrik lvblandskog. I bckdelen genom krret och en bit uppstrms har bcken kvar mycket av sin naturliga form. Lngre uppstrms r bcken utdikad och utrtad. Lngs hela strckan r det rtrikt kring bcken. Objektet r kraftigt pverkat av mnniskan, de ursprungliga hydrologiska frhllandena r kraftigt strda. P en del stllen finns ven pverkan frn tidigare sltter, bete och tktverk-samhet. Den blottlagda bleken r hrd av upptorkning och tramp. Hr r gott om tramp- och mopedspr.
