Ecological studies on Aerangis biloba (Lindl.) Schltr. (Orchidaceae) in NACGRAB field gene bank, southwestern Nigeria.


This study was conducted to estimate the population and distribution of Aerangis biloba in the field of National Centre for Genetic Resources and Biotechnology (NACGRAB), Ibadan, southwestern Nigeria. The study indicates that the species is abundant in the sampled area, as a result of good population of the selected phorophytes. A. biloba was observed only on nine trees among over 160 trees present in the sampling area, suggesting that these nine trees could act as phorophyte for A. biloba of which, Irvingia gabonensis and Irvingia wombulu harbored the highest number of orchids.


The paper gives a synopsis of the economic and ecological significance of orchids. It also recommends controlled harvesting, reduced deforestation and establishment of orchid gardens as some of the effective ways of enhancing orchid conservation in Nigeria.
