Additional Details (if available)

This species is the most commercially important of the mahoganies. The level of exploitation has led to the exhaustion of supplies particularly in the northern parts of its range. Regeneration of the species is stochastic, depending in nature on large-scale disturbance. This ecological strategy makes mahogany vulnerable to logging regimes. Harvesting and processing are generally only 50 percent efficient. There is, at present, little economic incentive to manage natural stands sustainably.

Name

Emma Hemmerlé

Scientific Name

Swietenia macrophylla

Common Name(s)

Big Leaf Mahogany

Type of Use

Extractive (i.e., the entire organism or parts of the organism are removed from its environment)

If extractive, for the target species, is this use

Lethal

Does this use involve take/extraction of

The whole entire organism

How is the primary use carried out?

Logging and/or Wood Harvesting

Are specific characteristics/traits being targeted?

Unknown/not recorded

Purpose of Use

Largescale commercial exploitation for trade

What is the main end use for any living organisms, parts or products taken/extracted?

Building/construction

What is the trend in the level of offtake within the period covered by this record?

Unknown/Not Recorded

Is there a regulatory or customary regime in place to govern this use?

Yes, formal but regular non compliance

Additional Details (if available)

Appendix II listing, the second-most stringent category of CITES protection, requires verification that internationally traded individuals or volumes of listed species have been harvested legally and in a manner that is not detrimental to their role in ecosystems where they naturally occur; however, legislation clearly mandating CITES implementation does not yet exist in some range nations; agencies responsible for evaluation and control of forest management often lack the the technical and enforcement resources to ensure legal compliance;
