Primer registro de Pteridium caudatum (Dennstaedtiaceae) en la isla de Providencia, Colombia

Acta Biologica Colombiana 06/2011; 16(1):225-232.


We report for the first time the presence of the invasive fern Pteridium caudatum (L.) Maxon Old Providence Island, Colombia. The species was found as an ornamental plant in house backyards, as well as in the wild in the locality The Peak, the best preserved area of the island. We discuss the ecological implications associated to the presence of this species.

    • "The vegetation of the islands is classified as transitional forest, finding elements of both the dry forest and tropical rain forest (Gonzalez et al. 1992; Lowy 2000). The natural vegetation has been completely transformed on San Andres and on the island of Old Providence it is relatively well preserved (partially altered) in the higher parts of the island (Marquez 2006; Tobar and Gavio 2011). It has been estimated that 77% of the flora in the Archipelago is endemic and the remaining 23% are introduced species (Lowy 2000). "

    ABSTRACT: Fifty seven new records of vascular plants are reported for the Archipelago of San Andres and Old Providence, part of the International Biosphere Reserve Seaflower. Of these, about 81% have been introduced for agriculture or ornamental purpose. With these introductions, we report ten new families and 30 new genera for the Archipelago. The possible impacts of some of these introductions are discussed.
