Résumé :	Time and financial constraints often force conservationists to make ad hoc management decisions without sufficient knowledge to predict their effects. In particular, the effects of management on reproduction and survival are rarely evaluated and habitat dynamics are rarely taken into account. We evaluated the effects of three different forms of habitat alteration on the endangered Pale-headed Brushfinch (Atlapetes pallidiceps) in Ecuador during the phases of population increase and stabilization. More specifically, we monitored the effect of a natural experiment with three approaches (clearing, grazing and burning) to preserve the semi-open habitat of this species on the reproductive success of 220 breeding events over seven years and on the survival of
