According to a March 2023 extract of the Florida Plant Rescue Database, Fairchild Tropical Botanic Garden holds 1 accessions of Banara vanderbiltii totalling approximately 61 seeds representing 5 maternal lines.
Known from 2 natural sites with only 6 and 10 individuals respectively. Threatened by development and cattle grazing. Restricted to a specialized environment.
The primary threat to this species is deforestation and selective cutting for agriculture, grazing and production of charcoal (USFWS 1986 a, b, and c). Extensive coffee planting in the central hills iof Puerto Rico has further increased negative pressure
There are approximately 18 known individuals in the wild (USFWS 1991). A second population was found several years ago - a disjunct population original site was on limestone; new site is higher and on a different substrate a single group of plants in the limestone hills west of Bayamon with 2 mature trees and 4 saplings.
Banara vanderbiltii is being successfully grown at Fairchild Tropical Garden. Seeds produced from the Garden's Conservation Collection may become a viable seed source for reintroductions in Puerto Rico. Plants have also been distributed to Florida's horticulture community as an ornamental species. These additional individuals may also aid in creating a viable reintroduction population.
The Recovery for Banara vanderbiltii calls for further protection of remaining individuals by gaining protective status and eliminating military training in sensitive areas (USFWS 1991).
Population monitoring and general plant reproductive knowledge, such as pollination ecology, seed dispersal mechanisms and recruitment success need to be investigated.
