  abstract = {{T}o conserve tropical forests, it is crucial to characterise the disturbance threshold beyond which populations of tropical trees are no longer resilient. {T}his approach is still not widely employed, especially with respect to the effects of moderate disturbances. {C}ompensation effects, such as positive interactions among plants, are addressed even more rarely. {W}e attempt to identify the extents to which the distribution of the keystone palm tree {C}eroxylon echinulatum is regulated by various regimes of deforestation in a threatened tropical montane cloud forest in the {N}orth-{W}est {A}ndes of {E}cuador. {T}he demographic structure of this palm tree was examined in three habitats: old-growth forest, forest disturbed by selective logging, and deforested pasture. {P}atterns were related to stand structure, microclimate, and soil composition. {S}eedling desiccation owing to severe aboveground water stress led to the absence of juvenile palms in pastures, and thus was predictive of a near extinction of the species in this habitat. {H}owever, shade provided by dominant bunchgrass in pastures considerably reduced above- and belowground water stress by diminishing light intensity. {S}elective logging resulted in a higher density of individuals in disturbed forests than in old-growth forests, but was associated with a spoiled spatial structure. {T}herefore, the protection of residual old-growth forests is a prerequisite for the conservation of {C}. echinulatum, although secondary forests might act as provisional refuges that promote its resilience. {T}he reduction of water stress by nurse grasses in pastures represents a promising approach to promote the resilience of tropical tree species and their associated communities after deforestation.},
