取樣方法

Species and subspecies which reproduce and establish new populations as of 1800 and those which have established themselves (without human assistance) before 1800 in Norway were considered. Non-native plant species that have established themselves after 1800 are not included and are given the category NA (Not Assessed).

方法步驟描述:

1. All species are assessed against the five IUCN criteria.The assessments are made based on the current situation, as well as developments in the near past or future.
2. Criterion A: Severe reduction in population size. More than 30 percent reduction over an assessment period of 3 generations (min. 10 years, max. 100 years). The species has recently experienced a severe decline in populations size, or there is strong reason to expect a significant decline in the near future.
3. Criterion B: Restricted geographic range. Less than 20.000 squared kilometer or an area of occurrence smaller than 2.000 squared kilometer. This criterion is combined with at least two sub-criteria: a) severe fragmentation or few locations; b) ongoing decline in population size or area; c) extreme fluctuations.
4. Criterion C: Limited population size. Less than 10.000 mature individuals and ongoing decline in population size, possibly combined with an unfavorable population structure (very few mature individuals in each sub-population or a large proportion of mature individuals in one sub-population) or extreme population fluctuations.
5. Criterion D: Very few mature individuals. Less than 1.000 individuals or a very limited area of occurrence (less than 20 square kilometers) or few locations (less than 5 locations). Species with a limited area of ​​occurrence/few locations can only be red listed if there is also a real threat to the location. Species can be red listed according to the D criterion even if there is no ongoing decline in population size.
6. Criterion E: Quantitative analysis of the risk of extinction in the wild. Less than 10 percent probability of extinction in a one hundred year perspective.
7. The species are assigned one of the IUCN categories based on the criteria: RE (Regionally Extinct), CR (Critically Endangered), EN (Endangered), VU (Vulnerable), NT (Near Threatened), LC (Least Concern), and DD (Data Deficient). The NT category is assigned when a species is close to satisfying one or more of the criteria based on national threshold values.
