Resumen: "Background: Understanding the effect of perturbation, be it natural or anthropogenic, on the demography and dynamics of the plant populations can help conservation management planning.Aims: We assessed the impacts of management of a shade coffee plantation on a population of Oncidium poikilostalix (Orchidaceae).Methods: We studied in a coffee (Coffea arabica) agroecosystem the impact of the current traditional management [T] and two hypothetical epiphyte control management scenarios (intense ‘desmusgue’ [ID] and moderate ‘desmusgue’ [MD]), on the only known Mexican population of O. poikilostalix. Based on 3 years of field demographics data, the population dynamics of the orchid were projected using T, ID and MD scenarios for 20 years into the future.Results: Under the current management T, the population of O. poikilostalix was projected to grow continuously (? = 1.102). Conversely, under management ID, the loss of individuals would lead to a sustained population decline (? = 0.843)"
