The prevalent belief is that clearing increases carrying capacity for livestock by increasing herbaceous vegetation, yet little empirical evidence exists to support or refute the contention. We investigated the implications to small ruminant nutrition of clearcutting in the semiarid tropics of northeast Brazil. We found that biomass of herbaceous species increased sixfold following cutting of trees, but much of this increase was in the form of poorly palatable stem. The large supply of leaf litter from woody species that was typical of uncleared areas during the dry season was replaced by persistent green foliage on coppicing trees the year following clearing. This green foliage may enhance the nutritional quality of the diets of sheep and goats foraging on cleared areas during the dry season.  aAnimal nutrition  aChemical composition  aClearcutting  aForage  aGoats  aPlant litter  aSemiarid soils  aSheep  aWoodland soils  aCaatinga  aCaprino  aComposição química  aFloresta  aForragem  aOvino  aPastejo  aProducao  aSerapilheira  aCoppice  aHerbage production  aLeaf litter production  aRegião Semiárida  aSemiarid woodlands  aSistema de talhadia1 aPROVENZA, E.
