Mexican government agencies such as Semarnat Ministry for Environment and Natural ResourcesConabio National Commission for the Study of Biodiversity – a scientific authorityProfepa Federal Attorney for Environmental ProtectionInecc National Institute of Ecology and Climatic Change – a scientific authority and policy makerCNF National Commission of Forestryand DGVS General Directorate of Wildlife – part of Semarnat, and in charge of regulating wildlife management and game are in charge of listing threatened species, protecting the listed species, designing and developing conservation programs for native species, and removing introduced species Semarnat, Mexican desert tortoises, including Gopherus agassizii now restricted to the United Cinservacion, but with an isolated population in Baja California Sur Murphy et al.

The conservation status of the freshwater and terrestrial turtles of Mexico: In other words, conservation of species promack become a government problem rather than merely a biological issue. Finally, we thank J.

We tracked the NOM over the three past versions to the species level only because of the lack of subspecies availability data in the previous issues Sedesol, ; Semarnat,and the number of species included changed slightly from 23 into 28 inand to 29 in To sample and calculate the approximate species area of occupancy we used a grid of 1, hexagons with an area of km 2 each.

Around the world, the most important threats for turtle populations are habitat loss, habitat degradation, poaching, introduced species, and subsidized predators Klemens, Patrones de diversidad espacial en grupos selectos de especies. More research and data are needed on Kinosternon oaxacaeK. Due to the size, high biodiversity, and sociocultural complexity of Mexico, it is reasonable that Conabio, Semarnat, Profepa, INECC, and other government agencies do not have a comprehensive and trained staff to deal with all the conservation problems; however, this is not acceptable in the supposed 11th economy of the world.

To determine the area of occupancy categories, we sampled all of SNIB’s records in the following way: The answers to these questions should provide a clearer sense of whether including species on imperiled species lists i. Third, so far there are no quantitative results derived from the public policies on the conservation of non-marine turtles in Mexico.

Conservation biology of freshwater turtles and tortoises: A main goal should be to improve the prikack between the threatened categories of international and local lists, in order to meet obligations to focus research, funds, budgets, and other political efforts toward generating a benchmark of protection for such a diverse group of reptiles in the country.

Terrapene carolina yucatanawhich is very rare and difficult to find in the wild Jones et al. If not, 2 what are the main discrepancies between the lists, and why? They have a minimum level of protection; however, more data are needed in order to understand the conservation and demographic status of their populations. Discussion The lack consservacion concordance between the lists issued by the Mexican Government and those issued by international NGO’s and specialist groups such as the IUCN Tortoise and Freshwater Turtle Specialist Group is based on the disarticulation of the Mexican public administration, from the data available to the decision-making process.

The results generated in this paper expose several concerns about turtle conservation biology in Mexico and probably in other lineages. As a general trend, the NOM generally lacks the conservavion included in the Red List, meanwhile the Red List is also lacking taxa that should prinack included according to their status in the NOM and their distribution ranges Table 3. We reviewed each category and cluster them according to the definitions of threats for each category IUCN, b ; Semarnat, Since the Red List is not a regulatory apparatus, local lists such NOM should be strengthened empowered to become a comprehensive, systematic assessment that could interact with its counterparts, such as the Endangered Species Act in the case of the shared fauna between Mexico and re U.

The conservation of non-marine turtles in Mexico should be carefully revised and revisited. University of California Press; The world’s most biopogia tortoises and freshwater turtles. To gather and analyze geographic information in order to determine the geographic distribution of each taxon, we used the official records primsck from the government for all the turtles collected within Mexico.

Compared with other primaci such as crocodiles, sea turtles, raptors, parrots, and mammals, freshwater turtles and tortoises have been ignored by conservation efforts in Mexico Conabio, Revista Mexicana de Biodiversidad Supl. In other regions of the world such as the Americas, habitat loss plus habitat degradation are the main factors in turtle population reduction.

Land and freshwater forms. First, there is a lack of correspondence between Red List and NOM status; both lists should be concordant if the conservation policies followed by the Federal Government are to be in accord with international agreements and the conservation strategies and public policies on threatened species.

Most of the under recognition between lists is related to misunderstandings probably ignorance or lack of information and a very slow information update process between official lists issued by Mexican Government agencies and the international lists generally issued by specialist groups. We want to thank John Legler and Richard Vogt for inviting us to the Symposium on Mexican Turtles at the 11th Turtle Survival Alliance TSA meeting, at which the original ideas for this paper were presented and discussed in an early stage.

Threatened, endangered and vulnerable tree species: Also it has the second-richest turtle fauna in the world after the U. There is a group of species missing in the NOM for several reasons i.

Most of the time, conservation, taxonomic, and distributional data updates reach the people in charge of updating the lists and the decision makers with considerable delay. We also sum how many records fall in nature reserves federal, state, and municipal around the country.
