    Conservation
    Although virtually the entire population of Pseudophoenix ekmanii occurs in a national park, the palm is still harvested for its sweet sap which is fermented into alcohol. Decapitated juveniles attest to the activities of sap poachers. In addition, seed harvesting, if excessive, may threaten the reproductive health of the population.
    Biology
    Pseudophoenix ekmanii occurs at low elevations in the Parque Nacional Jaragua and Isla Beata. The vegetation in classified by Hager and Zanoni (1993) as Barahona Peninsula Dry Forest, and the substrate is limestone with little or no overlying soil. The region receives 630–800 mm of precipitation per year and has a distinct dry season from December to May (Hager & Zanoni 1993).
