Purpureum (elephant grass) is a traditional practice in Costa Rican dairy highlands (between 1300-2500 masl). People believe that the pasture grows greener under the trees [Combe, 1979]. Alder is not only advantageous for fodder production but also for fuelwood and timber. It produces an additional source of income to the small farmer. The potential area for this association was first estimated in 60,000 ha [Combe, 1979], but more recent estimations give figures of around 50,000 ha, including one third of this area in pastures already planted with alder [Canet, 1985]. The question of whether the species may have potential for use in agroforestry systems in countries other than Costa Rica and research needs for the species are also discussed.
