Bolson tortoise
Gopherus flavomarginatus
Bolson tortoise is a tortoise in the family Testudinidae — Gopherus flavomarginatus, recorded as Critically Endangered.
Appearance
The Bolson tortoise, also called the Mexican giant tortoise, Mexican gopher tortoise, yellow-bordered tortoise or yellow-margined tortoise, is a tortoise from North America.
Of the six North American tortoise species, it is the largest, having a carapace length of about 46 cm (18 in).
Range and habitat
In 2008, following the construction of federally subsidized ethanol plants, extensive corn farming operations began within the Mapimi Biosphere Reserve.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
In crisis
The most recent research, published in 1991 from data collected in 1983, estimates that fewer than 10,000 tortoises remain in the wild. Populations have declined mostly due to overcollecting for food and the pet trade. Even so, in the northeastern portion of its range, near La Sierra Mojada, populations of the tortoise are low.
This reclassification would move G. Flavomarginatus from Vulnerable (VU) to Critically Endangered (CR).
CITES lists this taxon on Appendix I. Confirm the current appendix on the CITES checklist.
