The knowledge of taxonomy, distribution and ecology for birds, mammals, sharks, skates, jellyfish and echinoderms is good. Many lesser insect orders are also well known and we have good knowledge about vascular plants in general.
- Vertebrates are the most well known in the animal kingdom
- Only 6 % of the described fungi species are well known
The knowledge of taxonomy, distribution and ecology is assessed as being especially good (Category 4 or 5) for 21 species groups across the animal (Animalia), fungi (Fungi) and plant (Plantae) kingdoms. No large groups in the Alveolata, Amoebozoa or Protozoa kingdoms are assessed as being well known. On the other hand, in the Chromista kingdom, there are well-studied subgroups among Oomycota and brown algae (Phaeophyceae).
Vertebrates are the most well known in the animal kingdom
Vertebrates (Vertebrata) are one of the best studied larger species groups. The knowledge of taxonomy, distribution and ecology is assessed as being extremely good for birds (Aves: 496 species), mammals (Mammalia, 92 species), sharks and skates (Elasmobranchii, 37 species).
Among the insects we have a good level of knowledge for butterflies (Lepidoptera, 2270 species). Various lesser insect orders area are also well-studied: dragonflies (Odonata, 50 species), grasshoppers, locusts and crickets (Orthoptera, 31 species), stoneflies (Plecoptera, 35 species), fleas (Siphonaptera, 51 species) and shrimps (Branchiopoda, 109 species). It is somewhat surprising that the knowledge of fleas is good, since parasites are usually poorly studied in comparison with their free-living relatives.
Among marine species groups, the knowledge status is particularly high for true jellyfish (Scyphozoa), stalked jellyfish (Staurozoa) and echinoderms (Echinodermata).
For the groups mentioned above, 85 – 100 % of the biodiversity in Norway is described.
Only 6 % of the described fungi species are well known
Of those species groups in the fungi kingdom which have been assessed, only five groups are considered to be well known. Three of these belong to Basidiomycota: 255 species of rust fungi (Pucciniales), 85 species of true smut fungi (Ustilaginomycetes) and 55 species of Exobasidiomycetes. Two species groups of Ascomycota are also assessed as well known: the order Erysiphales with 79 species (belonging to Leotiomycetes) and Taphrinomycetes (a cause of witch's broom deformities in trees) which has 31 described species. These well known species groups make up only 6 % of all described fungi in Norway.
