Kind of Rarity
D.Rabonowitz et al.1986 (in Conservation Biology by ed.M.Soule)

1.Geographical range: Whether a species occur over a broad area or whether it is endemic to a particular small area.

2.Habitat specificity: The degree to which a species occur in a variety of habitats or is restricted to one or a few specialised sites.

3.Local population size: Whether a species is found in large population somewhere its range or has small populations whether it is found.

THE CLASSIFICATION OF INCIDENCE for Fauna and flora, especially insects.
(DRAFT)
author : Vratislav Richard Bejšâk-Collorado-Mansfeld
Abstract
The papers give you classification for abundance of fauna and flora more accurate than present system. The Rare, common... etc is properly classifed into 2 different type of classification and finally proposed new joined type.
Introduction
The present time is very important for ecologist and environmentalist to claim how the fauna and flora is spread. What is rare, engaged or common specie.There is no any problems with higher flora and fauna as a orchids, mammals, birds etc. but the other parts as an insects are very badly or not at all with this type of classification.

The invertebrates are a most important part of fauna. They provide a source of food for other animals, but some of them are also listed as endangered, vulnerable or rare species. Insects in particular play an important role in the economy of nature, and hence they are a very important ecological component.

For example, New Scientist No.1655 stated: Insects play an especially important role in the river's food chains because, in terms of energy transfer, they help bridge the gap between those forms of primary production which would be indigestible or inaccessible to fishes and those which , through the insects' feeding activities (or the insects themselves), become available to the fishes. Furthermore, many of the insects consumed by fishes are arboreal or terrestrial species which fall into the water or are flushed into it during floods (or rains).

System Kult
This is the system developed by czech carabidolog for his Key : The Carabidae from Czechoslovakia, 1947)
Kult in his table of Abundance categorise each species to the group 1-8. The Gorups was settlet how many xpecimens he have seen during his10 years period where he revised round 120 collections and many years of another frequent identification for other 98 collectors.

Group
1 I have seen 1 - 3 exeplars (specimens) solitary, sporadic
2 I have seen 4 - 10 exeplars (specimens) very rare
3 I have seen 11-50 exeplars (specimens) rare
4 I have seen 50-100 exeplars (specimens) not abundant, plentiful
5 I have seen 100-200 exeplars (specimens) abundant, plentiful
6 I have seen 200-500 exeplars (specimens) very abundant, plentiful
7 I have seen 500-1000 exeplars (specimens) common 8 I have seen more than 1000 exeplars (specimens) very common

System Nohel - Bejsak

The whole area of occurrence of a given species totally covers the territory of a given country (for example Victoria, Montana, central New South Wales). In the country, the species occur in all or nearly all geographic areas and is being found in a wide spectrum of various biotopes. On biotopes , it is usually found in great abundance. To this group there belong species usually recorded as “widespread and very common”. The group is arbitraly designed as a group ................................................................................ F

The whole area of occurrence of a given species totally covers the territory of a given country. Nonetheless, in the country, the species does not occur in all orographic areas being confined to only some of them. it inhabits also fewer types of biotopes than species belonging to group “5”, usually preferring only one or few types of habitats. Here it is moderately abundant, only there belong species usually recorded as “widespread but infrequent”. The group is arbitraly designed as group ...................................... E

The whole area of occurrence of a given specie totally covers the territory of a given country .Nonetheless, the incidence of the spe cies is recorded from only very few places, well dispersed from the another, being mostly of a relic character. Species placed here in general occur on habitants with great natural riches, well preserved, being little or not affected by human activity. on habitat, the species is never present in great quantities, oftentimes being only incidentally taken. To this group there belong species usually re corded as “very sporadic, very rare”. The group is arbitraly designed as group ..................................................................................... D

The area of distribution of a given species cover only a minor part of a country, the border of the area of distribution just passed through the territory of the country. The species occur thus only in one or at most few orographic areas, and its incidence is strictly confined to them, so that there is a complete lack, of the species in other parts of the country. Nonetheless, in those orographic areas where the species still occur, it inhabits usually more than one types the species still occurs, it inhabits usually more than one types of habits and it may be fairly abundant on them. To this group there belong species usually recorded as being “very local but at the place where it occurs often found abundantly”. The group is arbitraly de signed as a group ............................................................................................... C

The border of the area of distribution of a given species just reaches the territory of a given country. The species occur thus only in one orographic area its incidence is strictly confined to it so that there is a complete lack of the species in other parts of the country, even in the neighboring orographic areas, if they are different. If they species does occur in more orographic areas than in the one, then the areas are very similar to the one another and are closely adjoining. the species is bound to such types of habitats as are those named in group “3” (see there), and is found here only incidentally. Species usually reported to be “very local and very rare” may, in a part, belong to this group, which is arbitrarily designed as group ....................................................................................................................... B

To this last group there belong species being hitherto only poorly known so that it is impossible to make reliable conclusion as regard to their area of distribution. To this group there belong mainly very recently described species or species, that have until recently been recognized as synonyms or lower taxons (abberations,etc.). This group is arbitrarily designed as group .............................................................. A


Some species are mostly occur in smaller or bigger “colonies” (for example as a Scolytidae, some species of Buprestidae, Scarabaeidae, etc.).The group is arbitrarily supply with letter ........................................................ g

Some species are occur only as a isolated individuals, maximally as a couple, the group is arbitrarily supply with letter ..................................................... I
