Colombia is the fourth country in the world with extinction risk of reptiles in Colombia was only completed The groups with the greatest number of threatened criteria. It is therefore recommended to prioritize species protected areas is also considered as a conservation greatest reptile species richness, after Australia, Mexico, because 80 % of the human population, and thus th the after thirteen years, in 2015. species are turtles and lizards. However, the most affected with greatest threat status and those categorized as DD. effort, although these have not been reaching and Brazil. Historically, reptiles have suffered great economical development of the country, is located there. Of the 510 species and 2 subspecies that were groups (percentage of threatened species over total Similarly, a heads up is important because for all species expected results. In addition to threats that are anthropic pressures since some species are captured for In 2002, the first extinction risk evaluation for reptiles evaluated, 9 % (43 species and one subspecies) were species in the group) are crocodilians (50 % of species habitat degradation, transformation, and loss is a constant particular to each species, all reptiles, especially consumption, held as pets, and seeked for the use of their was developed. In that time, crocodilians and turtles were categorized under a threat category: 2 % (11 species) are threatened), followed by turtles (37 %)1. threat1. those distributed in the regions of the Caribbean skin. In other cases, reptiles are also sacrificed because mostly evaluated since for snakes and lizards there was Critically Endangered, 3 % (16 species) are Endangered, Based on the information analyzed, it may be and Magdalena, are threatened in great part due to people fear them. To all of these threats are also added still no complete species list for Colombia. According to and 3 % (17 species) are Vulnerable. It is also worrisome concluded that it is essential to start generating CONSERVATION STRATEGIES habitat degradation, transformation, and loss. This the loss, transformation, and degradation of their habitat, the guidelines of the International Union for Conservation to know that 20 % of reptiles in Colombia do not have standardized population data, as well as evaluating and To appease threats, different strategies have been shows that there is not a rigorous implementation which especially affects those species in the Caribbean of Nature (IUCN), these evaluations must take place information of any kind, eluding proper evaluation. These quantifying the threats that affect different species. developed. Conservation plans (at species or group of environmental norms inside of the territory, nor is slopes and the basin of the Magdalena-Cauca Rivers every eight years; however, the second evaluation for the species are categorized as Data Deficient (DD)1. These aspects are the most relevant while applying IUCN scales) have been created, and the establishment of there an integrated management of ecosystems.
