Sabal causiarum is being threatened by increasing development pressure on its suitable habitat and illegal harvest of the plants and seed for the horticulture trade. All known wild subpopulations have no more than 1,000 mature individuals each. The true impact of wild harvest across the species range needs to be established and urgent conservation measures should be established to alleviate wild harvest. The plant is classified as 'Vulnerable' in the IUCN Red List of Threatened Species(2018)[
