Species Info

  • Cordia alliodora


  • This article presents the findings of a study evaluating the biomass and composition of understory plants in 1- and 5- year old plantations at the La Selva Biological Station in Costa Rica.
  • This study sampled plantations of Cordia alliodora in monoculture plots and in polyculture plots with trees interplanted with monocots (Euterpe macrospadix, Euterpe oleracea, and Heliconia imbricata).
  • In the first year, there were no significant differences in the understory biomass (above-ground) between the monoculture and polyculture plots.
  • After 5 years, the biomass in the monocultures was significantly higher than in the polyculture plots. In the 5 year old monoculture plots, understory diversity consisted of 20 species from 15 families.
  • The authors suggest that understory growth in the polyculture was slowed by the competition with the monocots.
  • The author suggests that the diversity in the monoculture plots of Cordia alliodora can support a comparable diversity of regenerating species than in naturally regenerating sites of the same age since abandonment.
