Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii,v)+2ab(iii,v) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Köhler, G.
Reviewer(s): Hudson, R. & Alberts, A. (Iguana Red List Authority)
Justification:
Ctenosaura flavidorsalis has an extent of occurrence less than 5,000 km² and an area of occupancy less than 500 km². The population is estimated at perhaps less than 2,500 mature individuals, probably occurring in around 20 isolated subpopulations. Habitat is severely fragmented and is declining in area and quality. The species is also hunted locally for its meat. The population has declined by at least 20% (perhaps even more than 50%) over the last 50 years. With current rate of habitat loss, the population is expected to decline by at least 30% over the next ten years.
