We conclude that clearing can enhance seedling establishment in riparian abandoned tropical pastures, but other revegetation treatments intended to reduce soil drying and uprooting by flooding during early establishment should be evaluated to improve the cost-benefit of restoring riparian forest.Īndrews DM, Barton CD, Czapka SJ, Kolka RK, Sweeney BW (2010) Influence of tree shelters on seedling success in an afforested riparian zone. Both pre-existing and planted trees ameliorated microclimate to produce better conditions for establishment of new trees following natural regeneration. Tilling did not have any consistent effect on growth, but it appears to counteract the positive effects of clearing. Clearing also significantly increased seedling growth of some species, suggesting competition release. Clearing but not tilling enhanced seedling survival. Flooding events also produced high seedling mortality (80 % after the two first events). Survival was negatively correlated to vertical distance to water level, highlighting the importance of the short but severe dry season that may occur in the humid tropics, which reduced survival by >60 %. Seedling survival was low (19 ± 3 %), ranging between 3 ( Brosimum alicastrum, Moraceae) and 38 % ( Pachira aquatica, Bombacaceae). We tested the effects of grass clearing and soil tilling and analyzed seasonal variation of vertical distance to water level, and changes in tree performance, microclimate, and vegetation biomass after planting. We investigated whether grass competition and soil compaction together with seasonal drought and flooding limit the establishment of seven tree species experimentally planted in abandoned riparian pastures in Southern Mexico. In small-scale restoration projects revegetation is a common technique, but its success depends on the plant species used and some environmental filters. Anthropogenic disturbances frequently exceed resilience of riparian forests.
