Conservation status
Vulnerable
Threats
The rainforests in the Lesser Antilles are usually quite well-protected, because they provide the island with drinking water.
Volcanic eruptions, landslides and logging for roads and other development pose a threat to this slow-growing species.
Trends
The populations are decreasing or stable, depending on the island.
