Descripción :	This study aimed to assess biomass and nutrients from the litter in a conservation area in themunicipality of Alegre, ES. The study was conducted in three different forest covers included in theArea of Ecological Interest (ARIE) Laerth Paiva Gama, being a Native Forest (MN), a Reforestationof Eucalyptus and Acacia (REA) and Reforestation of several species (RED). The litter layer wasmeasured by the amount of biomass, the content and accumulation of nutrients in both harvests,the first in the late dry season and the second end of the rainy season. In all the coatings, thequantity of biomass was greater in the dry and followed values decreasing the amount of biomassin both forest cover: REA > RED> MN. The levels of potassium, magnesium and boron, present inthe litter were higher in the dry season, however the levels of nitrogen, phosphorus, calcium, sulfur,copper, iron, manganese and zinc, and organic carbon content did not differ between periods ofcollection, only being discrepant between forest cover, no seasonal variation. The type of forestcover has little influence on the levels of nutrients and in the dry season the accumulation of litter,potassium, magnesium and boron were also indifferent to this variable. Este estudo teve como objetivo avaliar a biomassa e os nutrientes da serapilheira acumuladaem uma Unidade de Conservação localizada no município de Alegre, ES. O estudo foi realizadoem três diferentes coberturas florestais inseridas na Área de Relevante Interesse Ecológico (ARIE)Laerth Paiva Gama, sendo uma Mata Nativa (MN), um Reflorestamento de Eucalipto e Acácia(REA) e um Reflorestamento de Espécies Diversas (RED). A serapilheira acumulada foi avaliadapela quantidade de biomassa, pelos teores e acúmulo de nutrientes em duas épocas de coleta,sendo a primeira no final da estação seca e a segunda no final da estação chuvosa. Em todas ascoberturas, a quantidade de biomassa foi maior na estação seca e os valores seguiram a ordemdecrescente na quantidade de biomassa em ambas as coberturas florestais: REA > RED > MN. Osteores de potássio, magnésio e boro presentes na serapilheira, foram mais elevados na estaçãoseca, entretanto os teores de nitrogênio, fósforo, cálcio, enxofre, cobre, ferro, manganês e zinco,e o teor de carbono orgânico não diferenciaram entre os períodos de coleta, sendo discrepantesapenas entre as coberturas florestais, não apresentando variação sazonal. O tipo de coberturaflorestal exerceu pouca influência nos teores dos nutrientes e na estação seca o acúmulo deserapilheira, potássio, magnésio e boro também foram indiferentes para essa variável. Biomass and nutrients of accumulated litter in different forest coversAbstractThis study aimed to assess biomass and nutrients from the litter in a conservation area in themunicipality of Alegre, ES.
