What is the red list of iUCN?
The International Union for the preservation of nature and natural resources (IUCN) has published a comprehensive list concerning the state of protection of animals and plants. IUCN, as is often known, is considered the largest database of protection information in the world. List maintenance is a complex process that includes the work of several organizations and requires constant new research to update the status.
In 1963, when the original red list of IUCN was created, the organization was in operation for almost 20 years, because its establishment of multinational protection in 1948 was originally relatively small and instructions dictating information were relatively primitive. Over time, there has been an increased interest in the effort to protect the preservation of a larger amount of credible research and the list has grown extremely. In 1988, all known species of birds were evaluated and the contests of all known mammals were set at the beginning of the 90's.
starting with a yearEM 1996 adopted the red list of IUCN strict scientific standards for contributing organizations. Maternity groups, called the Red List authorities, are accused of assessing all data on their specific taxonomy and the protection status must be updated every ten years. The red IUCN list has many contributing organizations, including Birdlife International, the London Institute of Zoology and the World Conservation Monitoring Center. Through intensive mutual evaluation and petition system, IUCN Red List becomes one of the most scientifically accurate databases in the world.
Since 2007, the red list of IUCN has been over 40,000 species of animal and plant life. These species are divided by a state of preservation. The condition is described by a scale, from extinction to a specific concern. Species that are usually considered endangered usually belong to one of three groups: critically endangered, endangered and vulnerable.
According to the latest available Statistics Red List experiences an animal and rosTLiny huge decrease in population level. Between 1996 and 2007, the number of endangered vertebrate species jumped from 3314 to 5742, which means that 23% of all evaluated vertebrate species suffer from serious threats of extinction. Among the plants with endangered species passed from 5328 to 8447.
IUCN Red List seeks to maintain the number of extinction of plants and animals since 1500 NL. According to data available in the last year, the number of extinct species has increased to 785 and since 2002 there has been a constant increase. Although this data is relatively depressed for nature, it is not possible to understand the reality of threat and extinction. Some experts suggest that a tougen list is the best available tool to fight a growing extinction list.
One of the most important features of the Red List is the ability to monitor species according to the protection laws to see if the species is actually supported by effort. Despite massive campaigns for protection throughout Africa, two types of gorillas moved from endangered to critically endangered earsifice. IUCN's red list is able to help identify problems that prevent the recovery of species and can help mobilize organizations on nature conservation focus attention on the most critical factors.
