HJ 626-2011Standard on classifying the categories of Genetic resources (English PDF)

3.1 Genetic resources genetic resources

Actual or potential value (including the value of aspects of economic, social, cultural, environmental, etc.), from plants, animals any material containing functional units of heredity was, microbial or other origin, including the following species and species taxon (Subspecies, varieties, variants, species, strain, type), including individual, organs, tissues, cells, chromosomes, A variety of forms of DNA fragments and genes.

3.2 Extinct (EX)

All the evidence indicates that a species and species of these taxa last individual has died, the taxon that is considered Extinct.

3.3 Extinction in the wild extinct in the wild (EW)

All the evidence indicates that a species and species of these taxa individuals live only in cultivation, in captivity or only as a condition Naturalized populations living far away from its past habitat, ie that the taxon belongs to extinction in the wild.

3.4 Region extinct regionally extinct (RE)

If the People's Republic of China can be sure the range of a species and species of these taxa final potential reproductive capacity when an individual has died or disappeared, or the last individual of a previously visited taxon have died or disappeared, namely recognition Extinct taxa that belong to the region.

3.5 Critically endangered critically endangered (CR)

When a species and species of wild populations of these taxa in imminent extinction probability is very high, that is consistent with a very dangerous condition (6 see endangered index), the taxon that is listed as critically endangered.

3.6 Endangered (EN)

When a species and species of these taxa are not very dangerous condition is reached, but the wild populations face extinction in the near future the probability is very high, that is consistent with the Endangered conditions (see 6 Endangered index), the taxon that is listed as endangered.

3.7 Vulnerable (VU)

When a species and species of these taxa are not critically endangered or endangered condition is reached, but in the coming period of time, its wild Higher risk of birth populations facing extinction, that is consistent with vulnerable conditions (see 6 Endangered index), the taxon that is as easy to Crisis.

3.8 Prohibited class exchange genetic resources genetic resources of prohibited exchange

When a biological genetic resources of high value, to prohibit the exchange of class conditions (see 7 socio-economic indicators), to be strict Grid prohibited from exportation of a class of biological genetic resources.

3.9 Limit class exchange genetic resources genetic resources of limited exchange

When the conditions for a class exchange genetic resources of high value, not allowed to exchange class does not meet the conditions, but comply with the limits (See 7 socio-economic indicators), without the consent of the relevant authorities for approval, prohibit leaving the country for a class of biological genetic resources.

3.10 Areal extent of occurrence

Comprising a biological genetic resources of all known, inferred or projected sites appear (not including the emergence of sites sporadic species) the shortest continuous boundary, including the enclosed area (Fig. 1A, B). Distribution is usually the smallest convex polygon to the degree Amount (all inside corners of the smallest polygon not exceed 180 °, and appear to include all sites).

3.11 Occupies an area of area of occupancy

A biological genetic resources "distribution" within the actual area of occupancy (not including the current situation even species) (Figure 1C). Occupy the scale is a function of the size of map sheet size of the area used when measuring the biological distribution of genetic resources. scale it should be based on relevant biological characteristics of the biological genetic resources, threatened types and available data to determine.

A. Represent the known, inferred or projected spatial distribution of biological genetic resources appear site.

B. Indicates a potential distribution area boundary, the area within the boundaries of the area is the distribution of genetic resources.

C. It represents an area occupied by the calculation method, the total area of the site that is where each appears like a square lattice.

Example 1 between the distribution map and the area occupied

3.12 Quantitative Analysis of quantitative analysis

According to the known life history, habitat requirements, and risk factors caused any specific information management methods to estimate any form of analysis of the possibility of the extinction of a biological genetic resources.

3.13 Downgrade and upgrade downgrading and upgrading

According to increase or decrease a biological genetic resources and the value of the degree of danger of extinction to adjust its rating process.

6.1 Indicators division

When the probability of a genetic resources, wildlife extinction is very high, that meet any of the conditions of 6.2 to 6.5, the the genetic resource that is included in the appropriate level, and application level adjustment from 6.6 to 6.7.

6.2 Extinction, and extinction in the wild areas of extinction

When a genetic resources, wildlife extinction, in the wild or regional extinction, all the biological genetic resources included in a Stage biological genetic resources.

6.3 Critically Endangered

When a wildlife genetic resources to meet one of the following five conditions, the biological genetic resources facing high off the field Absolutely dangerous, extremely dangerous should be included.

Reduction (1) populations, consistent with one of the very dangerous levels of four types of conditions shown in Table 2 below.

(2) the geographical scope to meet Table 3 critically endangered level distribution or possession of one area of the index, and the distribution or accounting

Table 3 has an area to satisfy the conditions 1 to 3, two arbitrary.

(3) the size of the population and to meet the recession in Table 4 critically endangered population level indicators and the number of mature individuals conditions of 1-2 one.

(4) the estimated number of mature individuals in the population of the critically endangered meet Table 5 level quantitative targets.

(5) Quantitative analysis showed the possibility of the extinction of wild populations of critically endangered meet Table 6 levels of quantitative indicators.
