Sphagnum affine

Sphagnum affine is a belonging to the section Sphagnum peat moss and is called in German-speaking regions " Related peat moss ", " Neighbouring peat moss " and "comb - peat moss ".

Identifying

Sphagnum affine is a Torfmoosart that shapes lawn or low and loose hills. It is usually slightly smaller than the other brown species of section Sphagnum (Sphagnum centrale, Sphagnum palustre and Sphagnum papillosum ). The color varies from green, yellow-brown to golden brown through to brown and even slightly purple. The stems are brown and contained in the epidermis or Hyalodermis clearly visible, wall strengthening spiral fibers. Each cell typically has two or more pores. The tribe leaves have dimensions of 1.3-1.9 mm × 0.6-1.2 mm. The twigs are more or less tapering and also have spiral fibers. They are four or five organized in clusters, two of which protrude sprouting, during 2-3 branches represent droopy branches. The Astblätter are usually dachziegelig or projecting on to the twigs. In the shadow forms a more fuel -engine arrangement is possible. You have ovate to elliptic shape and grow in size from 1.5-2 mm × 0.9-1.6 mm. The Astblättchen have on its convex surface hyaline cells with elliptical to more circular pores along the attachment. The chlorophyll cells are isosceles - triangular cross-section, showing the sheet at the top exposed Chlorocyten. However, they are well included on the convex bottom and therefore not visible.

Occurrence

Sphagnum affine is a both sides of the Atlantic occurring Torfmoosart, their distribution is concentrated on the temperate climate zone up to the subtropical climate zone. Specifically, this is the north-eastern part of America, from Canada to Florida and Texas, Central America and Europe on the eastern side of the Atlantic. Throughout much of the area it is a very common type of a series of wet minerotrophic areas. Specifically, it is well represented in wooded swamps and often also shows ruderal character. In other species of section Sphagnum (Sphagnum centrale, Sphagnum palustre and Sphagnum papillosum ), it can also occur together.

System

Sphagnum affine stands in the mono- generic family of Sphagnaceae within the genus peat mosses ( Sphagnum) in the section Sphagnum. According to a publication by Richard E. Andrus in 1987, this type is closely imbricatum with Sphagnum, peat moss Austin austinii Sphagnum Sphagnum and related steerei. He provides these 4 species in the taxon Sphagnum Sensu Lato imbricatum.

Threats and conservation measures

The destruction of the habitats of the peat moss Sphagnum is also affine endangered. The Federal Republic of Germany leads the way in the red list of threatened species as well as their state of Thuringia and their country Rhineland-Palatinate in the risk category 2 (" high risk "). The state of Brandenburg refers to the way because of extreme rarity as potentially at risk.

In the Red List of endangered species in Switzerland Sphagnum is affine in the category VU ( " vulnerable " ) out.

Like all species of peat mosses Sphagnum affine enjoys with the Fauna-Flora -Habitat Directive Nr.92/43/EWG in the updated version from 1 January 2007 certain protective mechanisms. The species is listed on Annex V and may be so occupied with withdrawal and usage restrictions. Furthermore, their habitat is provided by recording the 'acid Moore with sphagnum " in Annex I under protection, which SACs have to be designated for these habitats. Active raised bogs and active blanket bog are shown here even as a priority habitat types to be treated.

The German legislation defines Sphagnum affine on the basis of the Federal Nature Conservation Act BNSchG with all species of the genus in the Federal Wildlife Trade Regulation BArtSchV be particularly protected species
