Release of the 2000 purple record is a big landmark for IUCN. it's the first time that listings of animals and vegetation were mixed and the 1st time that the crimson record has been produced on CD-ROM. The 2000 purple checklist combines new assessments‹including all chicken species, many antelope and bat species, so much primates and sharks, all Asian freshwater turtles, extra molluscs, and lots of others‹with these from earlier guides. the mix of animals and vegetation right into a unmarried record containing checks of greater than 18,000 taxa (11,000 of that are threatened species) and the stream in the direction of better documentation of every species at the checklist implies that a hard-copy model of the purple checklist may run to numerous volumes. This, mixed with the truth that the pink record could be up to date each year, resulted in the choice to liberate the purple record in digital layout, through the area huge net and as a CD-ROM.

Artisanal and small-scale gold mining (ASM) is a poverty-driven job that gives a huge resource of livelihood for rural groups. the volume of mercury misplaced via 10 to fifteen million small-scale gold miners can succeed in up to 1,000 tonnes a 12 months, possibly contaminating a hundred million humans all over the world.

Likewise it is very difficult to predict with any certainty how many species, let alone which ones, will become extinct in the next one hundred years. These problems are further illustrated by the occasional rediscovery of species thought to be Extinct. The Vietnamese Warty Pig Sus bucculentus, was described from two skulls in the late 1800s, as the species was not subsequently recorded in any surveys it was treated as possibly extinct in the 1994 IUCN Red List and finally as Extinct in 1996. In 1997, a report was published indicating that the species still existed based on the identification of a partial fresh skull, which was obtained from some hunters (Groves et al.
As these tree assessments were all done relatively recently there was no need for any reassessments, but some changes were made in the light of new information and the SSC Conifer Specialist Group in their preparation of an Action Plan, reassessed many of the conifers (Farjon and Page 1999). In addition to the trees more than 300 new assessments encompassing a wide range of additional trees and other plants from Cameroon, Galápagos, Mauritius and South Africa, many of which were not listed in the 1997 plants Red List, were included.
The alternative of using the percentage of species that are threatened compared to overall diversity also creates problems because: 14 Red List 2000 06 September 2000 16:14:11 Color profile: Generic CMYK printer profile Composite Default screen Analysis with fewer species are likely to create greater error rates than countries with many • Countries species. For example, New Zealand has only four terrestrial mammals of which three are threatened. If two were incorrectly assessed, then instead of 75% of mammals being threatened there would only be 25%.
