The conservation of ecosystems and associated services depends on an understanding of the ecological process. Research has centered on regulation services with little research in support services such as nursery habitat and provisioning of non-timber forest products (NTFP). We evaluate structural characteristics of 210 trees of ten species of ecological importance from a Colombian oak forest and their relation to Philodendron longirrhizum (Araceae) and its production of aerial roots to obtain fibers. This species was present in the majority of forest tree species, the structural characteristics of the trees were not distinguished between hosts and non-hosts and the rugosity of the bark and diameter of the trunk of the host species influenced the number of total and harvestable roots. The nursery habitat offered by the oak forest results from the mechanism that P. longirrhizum uses to climb over a wide variety of hosts, and the provisioning service is fostered by larger host trees that favor the production of roots. For the management of P. longirrhizum we suggest the establishment of individuals over the majority of trees if the aim is the enrichment and the establishment of individuals on larger trees if the aim is to increase the production of fiber.
