HERNANDEZ-R., JULIANA  y  RANGEL-CH., J. ORLANDO. Vegetation of the wetland Jaboque (Bogotá, D.C.). Caldasia [online]. 2009, vol.31, n.2, pp. 355-379. ISSN 0366-5232.

The aquatic, helophytic and pleustophytic vegetation of the wetland Jaboque, Bogotá, Colombia was studied following the sigmatista-Zurich Montpellier approach. The fourteen communities growing along a water ecological series included those dominated by Schoenoplectus californicus, by Juncus effusus and by Typha latifolia. On marsh near the borders or in the inner of shallow pan the communities dominated by Polypogon elongatum, Rumex conglomerates and Carex luridiformis were growing. In the transition zone-between aquatic and terrestrial environments the tapes ("camalotales") dominated by Bidens laevis, Ludwigia peploides, and Polygonum punctatum were established. On the scarce mirrors of water appear the floating tapes with Eichnornia crassipes, Limnobium laevigatum and Lemna gibba. The diversity and richness of species and plant communities were greater in the wider and better conserved zone, near the Florida Park, where the majority of the plant communities mentioned in this contribution were represented. In the zone very changed (zone with channels) a few of communities were established, specially the camalotales with Bidens laevis, Polygonum punctatum and prairies with Pennisetum clandestinum (kikuyo) and Polypogon elongatus. The plant communities recorded from the Jaboque have a wide geographical distribution, growing on Andean lakes and marshes, specially in the high-plain around Bogotá and places of Cundinamarca and Boyacá departments.
