Formal name:  polyhemerobic
Local identifier:  TOP789
Definition:  individuals of the plant population (EFO:plant population) or species (Mayr:species) occur at habitats with extreme human impact (e.g. 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 allochthonous material)
Formal Unit:  unitless (category)

Comment:  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.
