General Information Distribution Chaetocalyx scanden is has a large geographical distribution. According to Rudd (1958) the native range of this taxon includes northern Colombia and Venezuela, eastern Brazil, the Lesser Antilles (Caribbean) and Southern Mexico. This taxon since been collected from Nicaragua and Costa Rica and may possibly be found in Honduras and Guatemala.

Threats C. scandens is not known to be specifically threatened or in decline, there are however a number of threats to the habitats in which the taxon is found. Extensive clearence for cattle ranching and shifting cultivation, wildfires, timber extraction and tourism are just some of the threats leading to habitat loss and fragmentation within the species range.
Past Present Future 13 None Conservation Measures This taxon is known to occur within the protected areas network but seeds have yet to be collected and stored as a method of ex-situ conservation in a seed bank.

IUCN Red Listing Red List Assessment: (using 2001 IUCN system) Least Concern (LC)
Red List Criteria: Date Last Seen (only for EX, EW or Possibly EX species): Is the species Possibly Extinct? Possibly Extinct Candidate? Rationale for the Red List Assessment C. scandens has a large distribution in Central and South tropical America and is found within a number of protected areas. The taxon is not considered to be specifically threatened or in decline. C. scandens does not meet the threshold for a threatened category and is thus rated as Least Concern. Reason(s) for Change in Red List Category from the Previous Assessment: Genuine Change Nongenuine Change No Change Genuine (recent) New information Taxonomy Same category Genuine (since first assessment) Knowledge of Criteria Criteria Revisio and criteria Incorrect data used Other Same category but previously change in criteria Current Population Trend: Stable Date of Assessment: 10/08/2010 Name(s) of the Assessor(s): Groom, A.
