trait details of "Hemeroby"

group of trait Hemeroby
description Hemeroby is a measure of departure from naturalness. Habitats and vegetation types are classified along the hemeroby scale from ahemerob (natural) to polyhemerobic (non-natural). Sites without plant life are metahemerobic. BIOLFLOR indicates the amplitudes of hermeroby, so that all levels of hemeroby are indicated in which a plant species can occur.

label name description
a ahemerobic
Human influence: Keine anthropogenen Einwirkungen
Species of rocks, bogs and tundra in parts of Europe; in Central Europe only in parts of high mountains. Human impact: none
o oligohemerobic
Human influence: Z. B. geringe Holzentnahme, Beweidung, Luft- (z. B. Schwefeldioxid) und Gewässerimmissionen (z. B. Auenüberflutung mit eutrophiertem Wasser)
Species of weakly utilized woodlands, growing dunes, growing bogs and swamps as well as near-nature heathlands and dry grasslands. Human impact: e.g. slight wood felling, grazing, emission from air (e.g. sulphurdioxide) and waters (e.g. flooding of floodplains with eutrophic water)
m mesohemerobic
Human influence: Z. B. Rodung und seltener Umbruch bzw. Kahlschlag, Streunutzung und Plaggenhieb, gelegentlich schwache Düngung
Species of forests with well developed bush and forb layer, heathlands, dry and nutrient poor grasslands, slightly utilized pastures and meadows. Human impact: e.g. clearings or rarely ploughing, material for animal bedding or mulch, rarely fertilized
b b-euhemerobic
Human influence: Z. B. Düngung, Kalkung, Biozideinsatz, leichte Grabenentwässerung
Species of intensely used pastures, meadows or forests and rich ornamental turfs. Human impact: e.g. fertilizing, lime application, use of biocides, slight drainage.
c a-euhemerobic
Human influence: Z. B. Planierung, stetiger Umbruch, Mineraldüngung, starke Bewässerung mit Abwässern
Species of arable fields with typical weed communities, of sown grasslands, poor ornamental turfs, intensely used forests with little developed ground layer, sewage fields. Human impact: e.g. levelling, regular ploughing, application of mineral fertilizer, irrigation with sewages.
p polyhemerobic
Human influence: Tiefumbruch (z. B. Rigolen), dauerhafte und tiefgreifende Entwässerung (und/oder intensive Bewässerung), Intensivdüngung und Biozideinsatz, einmalige Vernichtung der Biozönose bei gleichzeitiger Bedeckung des Biotops mit Fremdmaterial
Species of specialized crops (e.g. fruits, vine, crop rotation with intensely selected weed communities), landfills, spoil piles, debris (only during the first stages of succession, later transition to a-euhemerobic), partly sealed areas (e.g. cobbled ways, railroad tracks with chippings); community only rudimentary, habitat persistently modified. Human impact: deep ploughing, persistent and intense drainage (or intense irrigation), intense fertilization or application of biocides, single destruction of community and covering of the habitat with foreign (allochthonous) material.
t metahemerobic
Human influence: Vergiftete Ökosysteme, vollständig versiegelte Flächen
Community completely destroyed. Human impact: poisoned ecosystems, completely sealed areas.
