Threats This taxon is not recorded as being threatened or in decline, however there are a number of threats to the habitat. These include logging, conversion of land for agricultural uses and other anthropogenic developments such as road building and settlement expansion. These threats are leading to habitat loss and degradation.

Past Present Future 13 None  Conservation Measures This taxon is known to occur within a number of protected areas but seeds have yet to be collected and stored in a seed bank as a method of ex-situ conservation.

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 D. triloba is known from the central Amazon bason and its native distribution reches the north of Mato Grosso, Brazil and as such exceeds the threshold on 20,000km2 under criterion B. The taxon is considered to have be of a frequent distribution in central Amazon and observed less frequently out to the extremes of its distribution. The taxon is known to occur within the protected areas network and not considered to be experiencing and significant declines in population. It must be stressed however, that this species is ultised for its timber. The species is listed as Least Concern at present, however it is important to ensure that the utilization of this species for timber occurs at a level which may be sustained in the future.
